Title: 1/5th Scale V8 Blown
Post by: stevehuck on September 04, 2011, 06:11:57 PM: I was going to call this thread "Blown cylinder heads".

(http://i770.photobucket.com/albums/xx349/stevehuckss396/Misc/untitled.jpg)

This is the official kickoff of the blown Demon V8. I’m going to start a new thread so there will be no confusion to someone who starts reading the other thread.

I looked over the parts in the garage. I did make a lot of stuff for the second engine but when we started getting to the end a lot of the “I’ll make two” went out the window.

Among the big parts is the block. The block and oil pan are 100% complete. The liners and lifter bushings are pressed in and the bores are finished and ready for pistons. That will save at least a week and maybe two. The bell housing adapter and bell housing are also done.

(http://i770.photobucket.com/albums/xx349/stevehuckss396/Blown%20Demon%20V8/DSCN2181s.jpg)

The heads are done 100% and the valve cages are pressed in. One head has the valves installed. Both heads will need the rockers installed. All the pieces for the heads are made and tucked away for the later process.

(http://i770.photobucket.com/albums/xx349/stevehuckss396/Blown%20Demon%20V8/DSCN2182s.jpg)

The intake is nowhere. I made the blank but still need to do everything. This manifold will be completely different than the carbureted unit.

(http://i770.photobucket.com/albums/xx349/stevehuckss396/Blown%20Demon%20V8/DSCN2187s.jpg)

The valve covers are done but will need some kind of work to fancy them up a bit.

(http://i770.photobucket.com/albums/xx349/stevehuckss396/Blown%20Demon%20V8/DSCN2185s.jpg)

The camshaft is cut and assembled. I still need to do all the hand work to smooth out the cam lobes.

(http://i770.photobucket.com/albums/xx349/stevehuckss396/Blown%20Demon%20V8/DSCN2188s.jpg)

I also have the Timing cover done as well as the balancer and blower pulley.

(http://i770.photobucket.com/albums/xx349/stevehuckss396/Blown%20Demon%20V8/DSCN2191s.jpg)

I’m thinking the place to start is with the block. I’ll get it trimmed out with crankshaft, rods, pistons and so fourth and just roll from there. It will be a slow start because of the holiday ending and I have a lot going on in the next 2 weeks.

HERE WE GO AGAIN!!

Still using MeshCam and Cambam?

RICH

I was using LazyCam and CamBam but now CamBam only. Cambam can do all my parts but the 3D and lathe ops made the blower and sparkplug insulators possible. CB does it all for the kind of hobby I'm into.

I was making the insulators by hand. I have to cut so light that I was getting maybe 2 an hour if I didn't break them. Corian is very fragile. I found the lathe module in CamBam and created some Gcode. Then I borrowed a friends sherline lathe and spit them out every 6 minutes.

Off thread here somewhat, but think it's worth a few postings about what is being used to assist you in creating the Gcode for the parts you need to machine.
At the hobby level it is very hard to justify spending a lot of money to make life easy.
CamBam is certainly worth the purchase and was an easy transition for me to use. Has some nice features in it. Haven't tried the 3D part of it as i am still fooling with MeshCam.
I went to 3D training from work for 3 weeks, after that didn't want to even look at a pc at home. The worst part is between all the software used is that i find myself cursing all of them on the use of different keys to manipulate the graphics display.

I don't know about off thread. The reason I post this stuff is because #1 I think people will think it's cool to see but #2 If someone sees how it got done it might help them to do a similar thing. It's about learning from each other. I have learned so much from this board and others, I am trying to give a little back. I think it's great when people ask questions because they want to learn how something is done.

Graham

The plugs are not 1/5th scale. There are some things that you cant scale down too much. I have never measured them against a real plug but they do look awful big in the engine. They have a #8-40 thread. I do have insulators made for #6-56 plugs. I have seen smaller but never tried to make smaller.

I have had corian plugs in my V4 for 3 years now and it still runs as good as new.

Title: Re: 1/5th Scale V8 Blown
Post by: stevehuck on September 19, 2011, 02:18:28 PM: I got rained out at work today so I took a few hours in the garage. I guess this would be the official kickoff of the Version 2, Small V8. It is the same engine with a roots blower. I would guess this one will go a bit faster than the first but the way work is I don't know if I'll get back in the garage this month, or next month.

My friend Ron wants to bend the tubing in his new bender for the zoomies so i made the flanges today. The last time I made them I drilled and reamed the holes for the pipes. That didn't work well in .063 thick plate so this time I milled the holes .010 smaller and then reamed them to 5/16. Still not perfect bit I am alot happier doing them this way.

Title: Re: 1/5th Scale V8 Blown
Post by: stevehuck on December 15, 2011, 06:20:05 PM: I finally have something to report. My friend Ron fired up the tubing bender and I made the flanges and then he came over to silver solder the pipes together. Unfortunately this will be about all for a while. Still working too much but I hear it might end after the holidays.

Crankshaft, rods, pistons, and rings. I think I have about everything else made and stashed somewhere. I know for sure I have all the parts to complete the heads. I get those 4 items done and I'll be real close.

(http://i770.photobucket.com/albums/xx349/stevehuckss396/V8Demon/DSCN0944s.jpg~original)

I am going to try the George Britnell method so I started making a fixture to hold the crank for milling operations. Once complete I can pre-mill the throws so there will be alot less to remove on the lathe. The fixture looks big but I made it work for a future project.

No I cast it myself. I made the pattern a while ago. I poured it a week before the NAMES show and them poured a few more at the show. My pal Rick does casting demonstrations and that was the pour. Rick does the spiel and answers questions and I melted the metal and then poured.

If you look at this picture you can see the castings out front and the pattern peeking out from behind the engine.

(http://i770.photobucket.com/albums/xx349/stevehuckss396/Misc/b_73241.jpg~original)

This is me pouring the blower housings at NAMES. The flask is the blower and the bucket is a list foam pattern. I thought the foam went bad because it wouldn't take metal but it looked good when we pulled it out.

Drill all 5 centers in both ends. Then I rough out the ends and centers. Mill down the crank arms and then finish them. Then the last thing I do is finish all the mains last in the same setup.
