Just wanted to show off this cylinder head I made. It is for a small V8 engine that I'm working on. It measures only 4-1/2 inches long. The "blank" was made on a manual mill and everything else was done using LazyCam and Mach3!! I made 5 pieces.

Certainly have something to show off. Keep posting as you go along.
Are you going to CC them? ??? :D

No CCing. LazyCam RICH, LazyCam!!! I love LazyCam!!

BEAUTIFUL Steve !
Using LC, the degree of precision is so good, there would be no need to CC them.
Maybe Cnm them instead. LOL
I want to see this thing RUN ! Be sure to keep us posted.
What fuel will it be running on ?
THANKS !

Hi Russ!
It will run on gas. I dont need to but i use 110 octane "Turbo Blue" because it smells so darn good.
-
That's awesome. I think your gonna have lotsa people following this thread, myself included.
I just posted here to show the head because it was 90% CNC. There was some recent "bad press" with LC lately and I thought it would be nice to see what it can do. I have a thread at a model engine site that I update regularly with pics as i go along.

Question, how are you porting the block for oil passages?
That's the one thing the guy that did the roules Royce airplane engine would not divulge.
Is a car in the planning? >:D

I am not running a pressurized oil system. It will be a splash system like a Briggs Stratton. Once in a while the valve covers will need to be removed to lube the rocker arms. If you look at the bottom of the 4 pockets, there is a slot milled about .200 deep in the center of the pocket. When the cam tunnel is bored, those slots will break thru and oil will reach the cam and lifters.
No car planned. I will spend the better part of a year building this thing. I would hate to smash the thing up in less than an hour.

I intend to do the crankshaft on the lathe from some 1 inch square bar. The cam will also be turned in the lathe in a fixture. I wrote an article on making camshafts in the lathe using a chart to keep track of when and when not to cut the lobes.
http://www.mikes-models.com/camarticle.html
-
That answers my questions. Excellent and time consuming. Can't wait to see more pics.
The crank is easier than doing a cam. Just need a couple well placed center holes. I've made a couple larger ones for a punch press years ago.
Thanks for sharing , an excellent project.
-
Steve do you have a 4th axis for your mill? Cranks and Cams are fairly easy with a 4th. You can turn the blanks in the lathe to rough out and do all the offset work with the 4th. In bigger stuf we used round for the blanks to save time then did all the work on the mill and 4th
-
Steve ,
if the cam lobes are individual pcs. soldered on a shaft , then why not do the lobe profiles on the mill. Bore the shaft hole first , and clamp thru the bore to hold , and machine the profile. Lot faster.
-
wow! cool project!

No 4th axis. I could probibly cut the one off piece in less time as it would take for me to figure out the Gcode. I'm getting by with Lcam and cant figure out cam bam or any of the other cam programs. I'm fresh out of 30 day trials.

Not faster if you want a radiused flank. I am not a fan of flat flank camshafts. With the curved flank i am able to run a flat bottom lifter. If i mill a flat flank, i have to make roller lifters. They are fine for low RPM engines with a ball nosed lofter.
-
Steve we have run flat lobed cams and flat lifters well over 11k rpms in race engines.
-
Steve we have run flat lobed cams and flat lifters well over 11k rpms in race engines.
How do you keep the edge of the lifter from digging into the cam lobe? something needs to be curved or the edge of the lifter will meet the cam lobe and gouge the surface.
-
(;-) The design prevents the lifter from digging in. Your lobe must be correctly designed to run with your lifter. The curve is the actual ramp of the lobe. You can run right up to the edge of the lifter with the ramp design without problems. Over at the Andrews cam software you can download a free simple design program to design the lobe to fit properly. Also the trick is to design a constant velocity lobe but that is another story. (;-)

My thoughts, Exactly.
-
Ed does have a good Idea to do the lobes and then silver soldered or braze them to the shaft them to the shaft. Without a 4th that would be a good option (;-)
-
I would definitely do the crank in a lathe. The cam lobe profile in a mill.
The tedious part is getting all the cam lobes in the correct orientation on the shaft.
How much valve lift will this engine be running? and what ratio rockers. Curious.

You are talking about a curved flank lobe. We are on the same page. I have milled a cam with a curved flank and i have made them on the lathe and the lathe is about 4 times faster doing it the way i do. I do make one piece cams, not the built up type. Nothing wrong with them, I just perfer the one piece design
Alot of guys just cut into a lobe, turn the lobe, and then cut there way out making a lobe with flat flanks. It is faster but the time spent making roller lifters or ball nose lifters needs to be added in.
This cam was made for a V4 i finished a few months ago. I get alot of positive comments on the sound.

Steve the way we do it here is generate the lobe profile. Load the blank into the 4th between centers. Rotate to a start point on the blank. Cut the profile onto the first lobe. Move over in X to the next lobe rotate the cam to orientate the next lobe center and cut that lobe then on to the next. Once you start it is very easy to index the separate lobes at the proper lobe centers. IF you want a split profile just substitute the intake profile for intakes and exhaust for exhaust.
I am sure your process works for you but 47 cuts per lobe?? that is a lot of setup(;-)
Keep us up to date on your project. Mini's look cool but I will stick with the big boys

The Cam in the posted picture was made start to finish in 5 hours. Even if i had a 4th I'm not sure i could create the Gcode in 5 hours. I'm still real new to all this "drink beer while the machine does it all" stuff. This is just one of those times where it is faster to do it manually.
-
Doesn't matter how you do it Steve, It looks really good. And 5 hours is fast for a cam project.
Keep it up.
-
Heck the Gcode is the easy part you only have to do it once then use that on every lobe.
Ed is right it doesn't matter how you do it as long as "you do it" and enjoy it. AND you are doing a FINE JOB.
But if you ever get the chance to play with a 4th axis in CNC you may throw rocks at the lathe method(;-) It can do all the work on the crank or cam in one setup while you sit back and watch and drink iced tea (or beer). It might seem like MORE work at first but IF you have to build a second one. HUM load blank, load program push start button, drink iced tea.
(;-)
-

Dont get me wrong, I am open minded to it. If I had a 4th I might try it just to learn something new. I also want to make some blower rotors in a rotary axis but i have none.

Got a bit more done on the block. I went down both sides of the block with a 5/8 ball nose to give the block it's final profile.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN2223s.jpg)
Then with the block upside down, finished the profile.

I think for now the block is done. I still need to drill the hole for the distributor but i'm going to wait and drill thru the manifold and block at the same time. It just hit me how small this thing is.

I made the timing cover today. The cover was cut using the CNC machine then the counterbores were made manually in the drill press. I now have to chuck it up in the lathe and bore the inside to recieve the front crank seal. I think the cover will be polished and buffed to a high gloss.

For Cad I use Alibre. I have been with it for about 2 years and find it incredibly easy. For Cam I use LazyCam for everything. I was looking for a 3d cam program for things like the blower case and found CamBam but I cant figure it out. I must have tried meshcam because when I downloaded it to try it my 30 day trial period is up.

There is going to be a slight delay in the program. I have the Gcode for the intake 80% done and that part will be made shortly. After that I will be switching to CamBam for all my Gcode. If I don't jump into it fully, I will never learn it so that is what I will do. There wont be much happening while the learning curve is kicking my a$$ but in time it will be worth it. I will start out with the most simple parts that need pocketing and drilling and work my way from there. Bear with me and this thing will get back on track soon (I hope).

Hello everybody!
Finally managed some progress this week. I spent the weekend at the Detroit Maker Faire so today I almost finished the intake manifold. I drilled all the holes for mounting and fuel and water passages.Bolted it on the block to be sure it fits. The only thing left is to drill the distributor hole and finish threading a few holes and it should be a keeper.

The valve corvers took forever but all went well. I put a piece of sawed off stock in the mill and drilled the mounting holes and did all the machine work for the bottom side. All was done CNC. All 6 of them.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN2278s.jpg)
The block was rotated around holes were drilled to create the counter bore for the screw heads.

The top of the valve cover was brought to size
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN2281s.jpg)
Then the edges of the counterbore were rounded off with a itty bitty endmill.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN2284s.jpg)
Last the corner rounding endmill was used to finish off the top and create the top protrusion.

Hello all!
Had the chance to start on a 4 piece crankshaft. The plan is to make 4 pieces that lock together with a square end and socket. The square will allow me to index the crank arms in 90 degree increments. The design will also allow all the main bearings to be ball bearings.
The 2 center sections and the rear section all have one of the ends the same. So i spent the day turning the same end on 9 pieces. I made enough pieces for 3 shafts hoping for enough to make 2 when i'm done. The tip of this end will be milled square.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DSCN0523s.jpg)
The front piece is different so I turned the front shaft. All 3 have a real tight slip fit. I'm real happy with the fit of the bearing.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DSCN0528s.jpg)
Then the front pieces were rotated around and chucked into a collet. The rear of the piece was then finished. The rear of this piece will have a square milled into it to accept the piece behind it.

This should all become a little clearer as the pieces progress.

Hello All!
Made a bit more progress today. Chucked up the rear pieces and started to finish them up. I used my "bat wings" (brass inserts) on the jaws so i wouldn't damage the finish. Indicated to less than .001
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0534s.jpg)
I turned the shaft down to about .010 over size and then got the tail shaft ready for threads.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0536s.jpg)
Ran the threads on.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0538s.jpg)
Finished the shaft to .0005 - .001 oversize and then i like to bring the shaft to size using some 320 sand paper. This way I can work the taper out if there is any and i can usually hit my number within a few tenths.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0540s.jpg)
Then I put the taper on last.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0541s.jpg)
Thats about all until I get my hands on a 5/16 collet.

You do realize that you've now put the "build an engine" on some of our "to-do" list, don't you? I don't know if I should thank you or be disgruntled, because my list isn't getting any shorter. :) Thanks for sharing your build with us.

Finally made some progress with the crankshaft. Over the last day or two I managed to make the fixture to hold the pieces for turning. It's an ugly bugger but I did make a test piece and it works very well.
The first thing I did was to mill the square ends on the pieces that require them.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0609s.jpg)
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0606s.jpg)
The pieces are then put into the fixture and the turning begins.

Cross valve cages off the list. HOLY CRAP!! there are alot of them!!
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0736s.jpg)

Hello All!
Spent the afternoon pressing in all the valve cages. I made s simple drive dool slightly smaller than the ID og the cage and pressed them in a drill press. I like the fact that the press fit does not need to be very tight because the cage cant be shot out by the compression of the cylinder.
I also started to make some valves. These wont go as fast as the cages.
Stand By!

Hello all!
All 40 of the valve blanks are completed. They take forever but it will someday be worth it.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0762s.jpg)
To cut the slots I used my ER11 collets. I was able to put the valves in backward and slot the stem for the E-clips. I have an insert holder and a .020 slotting tool. Makes it easy to have a nice sharp tool because I stink at grinding tool bits.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0748s.jpg)
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0749s.jpg)
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0760s.jpg)
Then I made a few test pieces. I chose not to reduce the size of the stem at the head so I could hold the valve real close for rigidity. I took a light cut accross the face. I want the valves flush in the head and the hole for the valve cage is .250 so I reduced the OD of the valve down to .245.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0766s.jpg)
Then I cut the valve angle into the back surface.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0768s.jpg)
So now you all know what I'll be doing tomorrow!!

Hello All!
I finished all the bottoms and all that is left is to mill the hex on the shaft so they can be installed. For that I just used the rotory table in the mill with a collet holder in the center of the table. I have made 120 pieces in the last 2 weeks and now I have to make the valve spring retainers, 40 of them.

Hello All!
I made a few valve spring retainers this morning.
I turned the OD on a piece of 1/4 inch brass about an inch long and faced the end.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0797s.jpg)
Then spot drilled and drilled the ID about an inch deep.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0799s.jpg)
Then I used an endmill to make the flat bottom pocket for the spring clip.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0801s.jpg)
Then I cut a groove deep enough to create the step in the bottom that will insert into the spring.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0804s.jpg)
Then just move over the length of the step and part off the piece. Then starting with the step of making the pocket with the endmill, I continued until the inch of turned material was gone. It took 4 cycles of 1 inch of rod to make 43 pieces with 2 boo boo's.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0815s.jpg)

Hello All!
Well, I'm one step closer to having the rockers done. I managed to mill the slot in the nose of the rocker. I had some boo boo's along the way that I managed to fix sorta. Good thing these are hidden under valve covers!! I have three things to do still. I need to cut some clearance in the nose for the spring retainer. The rocker will pop the retainer off if i don't. Then the tail will get counterbored and threaded to accept a 2-56 screw. This will allow the pushrod to push on the screw instead of the aluminum rocker.
I am doing all this because I wanted to make some cool rockers. A much simpler rocker could be made in 1/4 the time. What the h7!! was I thinking.

You could send the photo if you want to. I'm sure they would get a kick out of it. Love there products. Everything between my cam and valves was Comp on my big Chevy.
Does Comp have a product that looks like these?

I've never came across one, with the offset, Not to say they don't make one. Though they do use a lot of pressed-in inserts that are offset.
Yep, Overloaded that looks close to the ones I programmed (though they look like the ole style). Hard to tell, they do make a lot of them, I programmed about 26 variations, (So far) parametric program, same basic shapes just a variation each. Small block, Big block Chevy/Ford/Racing of each style.
-
I'd post the program but it is all done in macro B with a rotating turn around station I created. Cycle time under 2.5 minutes each, complete. Uses a gantry robot and 14 station pallet loader. It looks like they sell so well I need to create a new center.
Some Fanuc ladder (Fapladder) additions to integrate the SMC hardware

Hello All!
Decided to do something easy tonight. I made the rollers for the rockers and the pins to pin the rollers. The rollers were a case of drilling the center and then parting them off a piece of 1/8 inch droll rod. The pins were just parted off a piece of 1/16 drill rod.

Hello All!
Made some progress in the way of the rocker pivots. They were a little trickier than i thought they would be. These things are only .156 round and .250 long. Made all the barrels first. Just used .156 drill rod and parted off the pieces and used a file to break the corners.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0869s.jpg)
I was able to set the barrel down on a parallel. I had one that is just smaller than the height of the vise jaw.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0871s.jpg)
I started using a center drill to spot the hole but the drill kept wandering anyway. I did'nt know this but found that if i used the center drill to drill as deep as it took to make a starter hole that was just smaller than the drill, It would follow the spotted area and worked much better.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0873s.jpg)
Then Just a drill bit to get the hole in it.

(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0881s.jpg)
I don't have the nuts done yet but I could not resist putting 8 rockers together just to see what it looks like. Of course the valves would need to be put in also. Everything looks ok so far. I have also used some JB weld to patch up the water jacket fiasco and hope to complete the heads by the end of next week?

Forgive me, but I worry slightly about the strength of the rockers. There's a fairly solid bit of metal above the pivot, but it does nothing. The load is all on the thin strip of aluminium under the rocker, and having some experience of aluminium I worry that this thin strip may stretch a little and possibly even break after a period of engine operation.
I may be wrong of course, but I wonder whether any calculations have been done on the expected strength of the strip?
Cheers
-
Would not hurt to put a small oil hole in the center of the rocker arm, from the roller side to the rocker pin hole. Include a small chamfer on the both sides to let oil collect and get distributed. Might even add one for the cup. There are more forces there than you might imagine. Then again, I can't imagine you running it for hours. Damn thing is cute. ;D

I am not worried at all. The springs are light and I will lube often. The spring pressure is some 5 Lbs or so. I also have the ability to make all I want.
-
I finally did it!!
I finally had some time to get the rocker arms done. I put a few together and tested the amount of actual rocking motion and of course, Not enough. I started the day re-cutting the slot by just a few thou. I might have gotten away with what I had but the pushrod length would have had to be exact so why fight it.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0892s.jpg)
Then the counterbore was done. I had a club member regrind a #2 counter bore bit so the pilot was a few thou smaller than the tap drill instead of the clearance hole. I was able to then counter bore the bottom for a caphead screw.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0893s.jpg)
Then all that was left was the tapping of the holes in the tail. Thru hole with 1/16 of material, what the heck. I used the "speed tap wrench" to get the job done.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0897s.jpg)
After that I started to make the adjusting nuts but after 2 I didn't feel like doing them. I wanted to have some fun instead of the production line stuff that has been going on lately. I decided to make the air cleaner lid after looking at JPeter's V8. He has a cool air cleaner on his and I was thinking "I want one of those". So I spent the rest of the session watching the mill make me one.
Sorry about the crappy picture.

Today I decided to finish the air cleaner lower pan. I found a piece of scrap large enough and faced it and turned the OD.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0908s.jpg)
The air hole and mounting hole were both drilled from the bottom side.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0910s.jpg)
The ID of the mount was bored with the boring bar
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0912s.jpg)
Then by some miracle, the part was parted off.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0915s.jpg)
Then the front was cut to shape and that is where the camera battery died.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN0918s.jpg)
It was finished off in the CNC mill. I think it is a close replica of a 14 inch Edelbrock. Only without the Edelbrock.

To make things worse, I'm building 2 with a spare head. Things that I would need 16 of, I am making 40 and in most cases 44-46 pieces. I think the worst is over now. I have all the parts for the heads done. Now I need to assemble all the rockers and recut the water jackets and the heads will be ready 100%. I even have the head gaskets done.
I would like to see the edwards. Any pics online anywhere?

Not of mine but there are a few on youtube and other photo sites, just search for Edwards Radial, it should come up with a few hits.
Plans are available on the yahoo groups Radial group. Very simple engine and nothing out of the ordinary.

Scratch carburetor off the list. Thanks to Mr. Bob Farr I was able to get a piece of brass to make the barrels. Everything is made except the throttle lever and the gaskets. I think I'm just going to wait until everything is done and make gaskets for everything all at one time.
The screw to the right adjusts the fuel and is adjusted at full throttle. The screw in the center will adjust the air bleed to lean out at idle.

Nuthin' but COOL !
Awsome don't even come close.
Ok, so now you need 2 carbs. And what are you going to use for a belt ?
Just put it on as a dummy, no rotors necessary (unless you got plans for em')
Way to go Steve !
Gotta see this thing blow some smoke.
Wicked !

I made 3 carbs a few weeks ago. It will use a 1/2 inch wide MXL belt. I have 3 lobe rotors planned. It will be no dummy.
-
Any reason why you decided to make your carbs rather than to use something like a walbro off the shelf?

Walbro would be way!!!!!! to big. Alot of the real small RC carbs are made to flow nitro. Also couldn't find one that looked like a holley.

Not alot of progress but progress none the less. The oil pan is offically done. I drilled the holes for the motor mounts. I also added a hole with a pipe plug to allow for checking the oil level. Now both of the boys are standing proudly on there legs. I mocked one up just to get a feel for how big they will be. SMALL!!

That's a 9 cylinder radial that I made from Cox .049 cylinders. Cox .049 were real popular single cylinder engines when I was a kid.

I guess I need to brush up on Lazycam...I can't even engrave with it yet, course I don't have the mill yet. Hope I can learn on the fly.

I switched to CamBam about a year ago or so. I have nothing bad to say about Lazycam but i wouldn't have been able to do the blower pattern with it so I needed something a little more powerful. Very happy with CB so far.

Finished the rods today. I used the CNC machine to cut the rod's profile while fixtured.
The rod plate was put on the fixture. The bushings extend thru the rod and into the fixture so the screws are not relied upon to hold the rods in place.

Today was fun time in the garage. Did nothing I was supposed to do and everything I wanted to do. I made an adapter plate that will go onto the intake manifold for the blower. The stock intake manifold will not work for this so I will eventually make another one.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1326s.jpg)
Then I made this. It's a long way from being done. Took 7-1/2 hours to make this from a 2-1/2 X 3 inch block.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1315s.jpg)
Then I made the adapter for the duel carb. Screwed up the ears on the flange that the carb sits on. Should have been rotated 90 degrees. I originally had a single carb facing forward. When I went duel carb I forgot they only fit side saddle. Should be fixed in the plans.

I have a Bridgeport, Bench top CNC mill that I built, and a manual lathe.
I do plan to sell the plans to build this thing. I have a mountian of work into the project as a whole so I can't give them away.

I had my pulley stock show up in the mail yesterday so there went my day off. The new day off is tomorrow.
I made this little fixture to hold the pulley on center. The tail section is exactly 3/4 so it can be chucked in a collet. The bore is snug as a bug. I put a 4-40 screw in the side to hold the stock from spinning. Not sure if i even needed it. I had a real wrestling match going when I tried to get the finished gear out.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1364s.jpg)
After the slug of pulley was in the holder, the stock was drilled and reamed. Then the inside was bored out to diameter. Then the entire fixture was taken over to the rotary table for drilling. Then the piece was removed and deburred. Easy enough. The most important thing i think would be to hit the center of the pulley OD. I would think the belt will have a hard time staying on in the pulleys were wobbling.

I could. I have the block and crankshaft drawn already. It would be easy to finish the drawings.

Steve, nice work, as a fellow engine builder, but newbie CNC I have enjoyed following your progress. Some of the club members with blown engines are achieving 4 to 6 lbs of boost. You had mentioned making a pattern for the blower, but since it lends itself to simple draft it might as well be done CNC.
This is not meant to Hijack the thread, but for those interested:
Clem will be at the GoodGuys Nationals in Pleasanton in August with the Deltec, Lou Chenot will show his 1/6th Duesenburg and I will show my V8. The word is that Jim Moyer will also show his 1/6th scale chevy.

If that is a photo of your engine in your avitar, that would make you Eugene. If this is you, you would never remember me but we met at NAMES 2007. I was just getting into the hobby and starting to build simple wobblers and air engines. Are you A BAEM'er? I have talked to Rhemus many times about the blower and he gave me 2 or 3 email addresses of guy's in your group. Never recieved a response from any of them. I guess they must have thought I was just another crack pot with big dreams. I have huge respect for that group and Rhemus and Mr. Moyer personally. Both real gentelmen and top notch craftsmanship from that entire group.

Steve, will you be showing off this masterpiece at NAMES?

I made some more stuff today. I made the balancer/fan belt pulley. I would have liked to make it look more real but I had to fit the clutch bearing in the piece.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1366s.jpg)
Then I made a special one. The only difference is the nose is turned down to a much smaller diameter and the hole pattern is drilled into the piece to hold the crank pulley on.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1368s.jpg)
Then I made the fan belt pulleys. They also recieve the fan and I will make the fancy cover like all the hot rod guy's have. The long one gets the fan out in front of the blower belt.

Yes Steve, I'm a long time BAEM member.
At one time I thought Coles sold castings of an OHV head and a blower for the Challenger. I loaned one of my V8 heads to a builder in Southern California and he machined two from the solid to convert the challenger to OHV. Since that called for a new intake manifold, it was easier to make a blower plenum, and then top it off with a the real thing. These same builders changed to a 360 deg crank instead of the 180 supplied with the kit.
The Black Widow which is a kit some of the members are putting together has a cast blower, but it is roughly 1/3 scale.
You're well beyond needing help with the housing, but IIRC they cored the castings for the rotors to keep them light.

I also have a 360 degree crank. I used the Chevy design and firing order tho i might do a 4-7 swap.
1/3 scale is huge. I am at about 1/5. It is all my current equipment will allow. Here is a picture with a pop can for scale.
Are you currently working on something else? Mr. Moyer told me he has started a 409 Chevy but I have not seen any photo's yet.

I just finished building a Helicycle, certified it airworthy in November, and flew it for the first time on 1-28. that has been a 3 year project.
As far as models, I probably had the 1/3 scale "F" head Harley Davidson at the 2007 NAMES show and while the crankcase is cast, I need to machine wax to invest in order to cast the cylinders. That is what brought me into the CNC arena. I made wood patterns and silicon molds to inject the wax into, but the fins are so deep and thin that it tore the silicon and ruined the mold.
I'll start a thread with a description so it doesn't clutter up yours ;D.

I don't know why I do this but I "cant not" do it. After making rod bearings and wrist pins I lay out the parts to be used and weigh them in grams.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1403s.jpg)
Then I put the light pistons with the heavy rods and weigh everything again.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1404s.jpg)
Then I put the heavy pins with the light sets and re weigh.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1406s.jpg)
Now I know I'm as close as I can get to balanced. I am real happy with that.
Then came time to press the sets together. The pins slip into the pistons and press into the rods.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1409s.jpg)
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1410s.jpg)
I put the assembly into the lathe and oiled it up real good. Let it run until everything was turning real nice. Took about 10 minutes.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1414s.jpg)
-
Steve, with your bore and stroke, 15000 rpm is not out of the question, so good dynamic balance will give a tabletop runner that sits still at high rpm and revs quickly.
The formula to determine the bob weights for the balance of a 90 degree V engine with big ends matched in weight and piston wrist pin and small end matched is 100% of the rotating mass plus 50% of the reciprocating mass per journal. I cast the bob weights in lead and then built a balancer to spin the crank. As it turned out the lightening holes were a scale match of the full size.
I realize you are past that point now, but I understand your "can't not" comment. Been there, did it. Looking Good.
Eugene
-
Sandcrab... how are you "catching" or viewing the heavy side with that pendulum style balancer?
-
The quick answer is I touch it with a marking pen, add clay until it spins true, weigh the clay and drill opposite from where I removed the clay until the chips caught on a magnet weigh the same as the clay. Then spin it again to check and repeat as needed.
-
Hi guy's!
Made some progress on a few things today. I'm trying to get everything ready so the next time the crankshaft comes out, I will have everything ready to put it back in for the last time. I made a couple more collets to hold gears for modification. I made one for the idler gears and this one to modify the crankshaft gear.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1421s.jpg)
Turned the hub down to the correct thickness. This will put the correct distance between the gear and the bearing.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1418s.jpg)
Then the OD was modified to work with the bearing. The bore was opened up to a press fit onto the crankshaft. This finished up the crank gear.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1419s.jpg)
I also made one for the idler gears. The idler just needed the hub removed. I also made the idler mounts. Only one of the idler gears is needed but I wanted to make mine like a Pete Jackson gear drive so i'm going to run 2 idlers.

After that I made my fixture for heat treating my rings. This fixture is made the George Trimble way. I included the fixture in the drawings but it is only good for 5/8 rings.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1423s.jpg)
Turned and bored the cast iron for the rings. Finished with 180, 320, and then 600 grit paper. Real happy with the finish and hit my number inside of .0002.

awsome work, there are no words good enough :-* - not u the part :)
-
The rings have cooled. I had to boil them to remove the anti-scale powder. I made them .001 thicker than needed so I will polish them with some 600 grit before installing them onto the pistons.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1447s.jpg)

I knew that!!
-
yup, not only is this fun to watch is informative. I've assembled a few hundred engines and thousends of transmissions but had no idea how sealing rings were made.
thanks again
-
Photo bucket isn't showing your fixture for these rings, but I got away from the anti scale compound by covering the heat treat fixture with this cover. I still added a little bit of paper bag to take up any excess oxygen. The center bolt holds it in place, and the extra collars are so I can treat shorter stacks of rings.
I developed this ring spreader after breaking 24 oil rings through the oil hole opposite the gap during installation. A ring is placed in the holder and followed with the small aluminum ring to keep things square. When the tapered plug is pushed through the ring is opened up evenly and the sheet metal wedge is placed in the gap. The small ring may be removed, and when the fixture is placed over the ring groove the wedge is removed and the ring snaps into place. One of the cylinders is the wet sleeve, the other is a tapered ring compressor.

One question I have concerning your cast iron piston rings - The bore and OD were turned, they were parted off then they were placed on a mandrel and heat treated but how did you make the split in the rings (O into a C) please ?

Wire cutters. They dont cut the cast they crack it. Get lined up real square and squeeze to crack them. At the size I made them, it's real easy.

"Wire cutters."
Nifty ! Never thought of that.
The only ones I made were a bit bigger, 1.6" or so.
The instructions I had said to gently force them over a slightly tapered mandrel until they crack.
Worked pretty good. I was surprised .... as usual. lol
Nice work Steve,
Russ
-
George Trimble also included a design for a ring cutter in his SIC article. It had opposing cutting tool blades ground like Steves wire cutters. The critical point is that the break is perpendicular, so that when the ring is mounted in the heat treat fixture the annealed diameter is not changed.

Rhemus told me that there is a better method that makes better rings than trimble's method. It will be in MEB shortly.

Well it has been an exhausting week. I had some trouble with the CNC mill. The Z axis would work fine for hours and all of a sudden it would skip steps. I think I narrowed it down to the drive. I rebuilt the control panel to include 3 Gecko drives and new 570oz motors. The machine now moves around so fast it's scary.
Now I should be able to get back to building engines!!!

Went ahead and put some valves in 2 of the heads. I found that about half of the valves had the groove cut to big and the clip would not seat into the retainer. I chucked them back into the collet and cut the grooves .002 deeper and they went together like they should.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1873s.jpg)
Then I decided to install the rocker studs more perminent. They had been screwed in finger tight forever.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1874s.jpg)
With the heads being done I nailed down my finished push rod length. I only had enough rod to make 12 rods but that will be fixed tomorrow.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1879s.jpg)
Then a set of rockers were assembled and put into place. Nothing is adjusted with the camshaft not properly timed yet.

(;-) TP
Nope! In the time it would take me to write the code I could make 2 by hand.
-
I have been working on a CNC Cam and Crank grinder function for MACH3 AND SheetCam. iF you had the lift points for the cam lobes it would take about 15 minutes or less to complete the Gcode.
You can collect the lift data by probing A cam in the grinder. Then transfer those lift points A/Z into a DXF drawing then Use SheetCam to translate the drawing into a A/Z plane gcode program that is compensated for the Grinder Wheel radius.
Once you have a Gcode program it is ALL about making as many as you want. Load the blank press the GO button and go about your business. When the cam is complete remove from machine.
It will even do CROSSOVER grinding of PAIRS (int/exh) of lobes alternating between lobes for each pass to help control THERMAL buildup.
IT WILL ALSO do the offset grinding for the Crank pin journals as well as the main journals. SAME basic procees right down to COPYING a crankshaft. Probe the rod journals in the grinder then transfer the data out to a DXF drawing. Into SC and back to mach3 for ginding. IT can even grind a crank from billet if you chose to. Best to rough it out first to save grinding time.
Just a thought, (;-)TP

Steve about how long does it take to produce a camshaft ? Crankshaft?
Just curious,(;-) TP

1 hour to make the fixture
1/2 hour to machine the blank
3 hours to machine all the lobes
Crankshaft was about 6 hours start to finish.

That's what I designed and it looks alot like my model. Maybe the flank radius is throwing you a curve ball.

Well I have had 2 people tell me they have completely modeled the engine and one more who has only a few pieces to go. They have reported the same missing dimension on the head. Other than that I think I'm out of the woods on the drawings. I don't see them changing much after this one update. The fact that it could be drawn by 3 people makes me believe there is enough info to build to completion. The plans have been updated to version 1.01. I'm going to wait a few weeks to see if anything else pops up and send out a fresh set to those who have purchased already.
Other than that i'm going to stick to the original plan of finishing the V8 project and then finishing the blower conversion. Hopefully I'll get back at it next week!!!
If interested, plans can be purchased for this engine.
-
Such a wonderful job you have made of this project Steve I hope you have many takers for the plans. (shame you can't sell the ability as well as the plans).

Scratch fuel tank off the list!
Work was cancelled for the day so i made the 2 end caps for the fuel tank. They are just 2 slugs of brass but if you want to increase the capacity of the tank the ends could be bored out.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1936s.jpg)
After polishing the tubing the holes were drilled for the filler neck and outlet fitting. I didn't call out the holes in the drawings because I felt everybody has a personal preference as to where the fittings go. The fittings were then soldered in from the inside.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1938s.jpg)
I cant remember where i saw this but the inside wall gets fluxed and a piece of solder is wrapped around the inside of the tank. The end cap is fluxed and installed. The prepared end is set on the table and a torch heats until the solder melts and bonds that end.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN1944s.jpg)
The same process is used on the other end and then the tank gets soldered to the mount bar. I rubbed it a little on the buffer. There is alot more buffing to do but you get the idea.

Hi Steve,
I think Sam and I both agree that everything aluminium should be anodized. ;D
(For those who have not done it before you can purchase complete kits of chemicals and dyes together with easy to follow instructions and stunning colours and effects are possible. Obviously care is needed handling and storing the chemicals so you really need a working area secure from children, pets etc).

even number work on dc/aux setups but many are odd too.
is that a torsional front hub/balancer?

When you build your V8 you can have as many blades as you want. Haahah!! The 8 blades actually came from a member of another board. Said something like "if I made one it would have 8 blades because" so I was making a new one anyway. I made it to his spec and posted it mounted on the engine the same day. Now he is making a 9 blade. I already have a design for a 13 blade if the hint of a challenge is made.
That is a mock balancer/pulley. It houses a clutch bearing so I can start the engine.
Have you seen the guy at CNC Zone who is building this engine at 1.5:1 scale? I think he will finish before me.

Give it a try! Start out with a simple steam engine. If that goes well build a milti cylinder steamer. If that goes well build a 2 stroke gas engine. Work your way up from the basics. That's the way 90% of the engine builders do it. Start small.

Getting closer!
I broke a sparkplug so I need to make a few more then it on to the exhaust pipes.

Yeah!! That sounds simple. I have a better idea. You build the dyno and i'll borrow it when I need it!! Haahahahha!!!!!!

(;-) I already built one for a micro motor ( RC airplanes). All it is is a disc mounted on an axle. 1 sensor to look at rpms and software to calcultate how fast the engine can accellerate the wheel up to a set rpm level.
Just a thought, (;-) TP

On second thought dyno testing can be very hard on race engines . The fact that it will run and SOUND sweet is enough satisfaction.

Just a mini update. The throttle lever is done and installed. I used a RC linkage kit for the ball and socket. Now the exhaust pipes are of the highest priority.

I have started on the sparkplug boot project. I am going to attempt to make a mold of some sort and cast rubber into the mold. I haven't decided weather to cast the boots onto the wires or make a boot to slip on the wire. I like the thought of reuseable boots but assembly would be alot easier with the wires molded in.
I have never done anything like this, Never seen anybody do it, or have any idea of how to go about it. Other than that it should be easy!
Here are a few pix of the master. From these the mold should be able to be made. I am not sure if I'm going to gate it side to side or front to back so I have not done anything with that yet.

Yesterday I made the second half of the boot mold. After being sent home from work because of a small fire and power failure in the refinery, I made the core pins and made a test run.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN2133s.jpg)
I could have mixed the material better. The color is not good. I think I pressed a little harder than I should have also. The result was great. I have made 5 boots now and they look better. I tried to color one with black pigment but after 1/2 hour in the mold it was still soft. Grey will look just fine.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN2128s.jpg)
They look a little big but so do the plugs so it is something i will learn to accept. I don't think I want to go any smaller.

It's a 2 part epoxy silicon rubber. Mix both parts in equal quantity and press it into the mold.

I had planned to make some kind of brass cap like the peewee project. I was searching the scrap box for some 1/8 inch brass and there was a piece of tubing in the box. I tried the id on a plug and it was a pretty good fit so i parted off 8 of them. I slipped the boot over the wire (harder than it sounds) and stripped the wire and tinned the end.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN2135s.jpg)
Then I tinned the piece of tubing. The drill bit was necessary to keep the tubing from sticking to the tip of the soldering iron.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN2137s-2.jpg)
Then the wire was soldered to the tubing as close to center as I could eyeball.
(http://i770.photobucket.com/albums/xx349/stevehuckss396/DemonV8/DSCN2138s-2.jpg)
Then I made a small tool to insert into the tubing to help coax the end into the boot as the boot was pushed back to the end of the wire.

Well using the method described in the earlier thread I got everything set. Installed the electronics and gave it a crank. It started to pop right away so i asked the wife to go get the video camera.
This is the actual first run of the Little Demon. The timing has not been set. The carb is about 1.5 turns out with 1 turn out on the air bleed screw. The rings are not seated the valves are not seated. Other than that it went pretty good. I'll have better video as soon as I get it running better.
14 months, 11 days.

Thanks Jeff! Yesterday was a very good day.
It's starting to get better. The smoke is starting to clear up. The engine is starting to respond to the throttle. I had to make the linkage today so I could set some kind of idle. I still need to get an Oring so i can get the water pump going and extend my run time so i can do some serious tuning.

Well fellows it's the day we all knew would come eventually. The Little Demon V8 project is offically done. After hanging in there with me for almost 15 months there photographic and video proof that this was not a waste of time. I am more than happy with the result and don't panic, I do plan to carry on to finish the blower motor but I need to take a few days off and relax.
I would like to thank all those who hung in there with me offering some kind words and sometimes a laugh and a half.
Many thanks!

I'm looking for a guy named John Tober, Tasman@
I have an update for the V8 plans and blower plans and your email address in my records will not allow me to send you the updates. Minor changes but I would like everyone to have the latest copy.

Things are loosening up and breaking in.
http://www.youtube.com/watch?v=FnbwsLysqGk

I just sent out an update and had about 10 "undeliverable" due to email addresses not existing anymore and other things. If you have purchased the plans and have not received an update, PM me your name and email address you used when you bought the plans. If I find you on the list I will update your information and get you the latest set.
I found out a few weeks ago that the distributor gear set I used was supplied by Berg who now has a $200 minimum order on online orders. I found new sources for the gears and seals. The drawings were updated to work with the new gears and over all should save you about $90 in material costs.
