It looks really great. When all is done,you have to make a movie with & without the blower for looking how the perfomance change.
Is that possible??

I could run them side by side i guess. I already have one running on the carb.

Pretty darn close!

This is just unreal!

The engine would look good in a slingshot dragster

Awesome work, Steve!!! It was great to see it at the MDMC meeting.

I have started on the linkage for the carbs. 2 small brackets, a shaft, and a couple of retainers to maintain position of the rod. This rod will rotate to open and close the carbs.

When you cad this stuff up it's real easy to loose track of just how small the parts can get. On the computer you can just zoom in a little more. Cant do that in the garage.

Especially as the eyes get older.
McMaster has rod ends down to 6-32 size. Sometimes I keep one on the desk and import the cad file from them to check sizings. Still, there has been plenty of parts I have drawn and end up saying "how the heck am I supposed to hold that to cut it"?
That blower is looking sweet!

These are #2-56 and the balls are 0-80

Dubro model airplane stuff at those sizes. I am deathly afraid of taps that small.

It's not that bad. Just go up a drill size from spec and your gold. In steel go up 2 sizes.

Got my pivot arms done. I think i'm going to spend the rest of the day making spark plug boots. Makes for a nice easy day.

Blower belts came in the mail today. The fit is perfect. With any luck I should be back at it early next week.

Vroom vroom.
Tried just motoring the blower yet?

If you mean, did I remove the gear and chuck the shaft in a drill motor and let'er rip, well that would be childish don't you think?

Of course i did! I didn't do it for very long and never tried to plug the bottom because I was getting some touching of the lobes. I still need to figure out a way to get the rotors indexed but of course I have a plan. Haven't had much time this week. Getting ready to show at the Maker Faire this weekend.

KICK ASS, Steve !!!

Freaking really nice work!!!

Wow, so realistic! Maybe I missed it, but what is involved in making the pully teeth profile to match belts like that? Like a numbered gear cutter, or..?

I purchased gear stock and cut it down to what I needed.
