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.




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. 



Looks mean as he!!

WOW!!!!!!
That has got to be one of the coolest things I have seen in a while!!
Did you make that with JUST your Mill and Lathe? if other machines what?
would you sell or give your CAD files?  Now I want to make one

Thanks Poppa for the kind words.

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.

Made a few more pieces.

Made the rear cover, front cover, and the gear case for the blower.

I really enjoy watching your progress. Thanks again for sharing with us.

I just found this forum and this particular thread is like crack!

Thanks Sam for the kind words.

Stoner, I laughed like hell when I read that one. Glad you like it!!

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.




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.




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.






That was my day!

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.

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.

Steve,

Really great work.

Is that a 10 cylinder, 2 stroke rotary engine I see in your in tray ?

Tweakie.

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.

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!!
