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.





Turned the hub down to the correct thickness. This will put the correct distance between the gear and the bearing.




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.




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.




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.






Loaded 27 rings into the fixture and they are ready for some heat.

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.





Then I put the light pistons with the heavy rods and weigh everything again.





Then I put the heavy pins with the light sets and re weigh.




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.






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.

Very nice work.  Thanks for posting the photo's.

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.

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 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.




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.




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.

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


Yes I will be there. I will be with my metal club. Not sure where we will be yet. I heard we will be out on the main isle.

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.

258
Can you make a V16? That would be superly powerful for a kit car of some kind..

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

259
If somebody wants a real challenge then one of these engines in miniature would be the one  >:D

Nice, where's the pics of the rotors that fits in that sucker?

Haven't made them yet.
