My 2nd running engine.

Its much better looking then my first. It will almost run on breath.

no plans, I just started cutting and drilling till it was done.

It runs fine.

Great job! I especially like the finish you put on it. The engine turned finish is something that you don't very often these days. How did you do it?

 

[tattoomike68]

I jeweled it with a stick I turned and staple gunned a peice of emeory cloth to the stick then just did it freehand in the drillpress.

I like a hand crafted look.

Looks good. Bet that was fun running it in the shop.

Yea, thats my brothers shop I dont have an air compresser. I have free run of that shop anytime I need it. It has most everything but a tig and cnc machines.

Mike,
Nice engine you have got there. Thats a big size for a wobbler, bet you wouldn't be able to puff that for long.
Isn't it a great feeling designing and making something, then it comes to life when you put a breath of wind into it.
Well done.

It does eat some air its .3125" bore .750" stroke. Its been done for weeks Im just now posting the pictures.

Looks great Mike.
That is one of the biggest home brew
wobblers I've ever seen running.
Nice work!

Damned fine work, Mike. That is one gigargantuous oscillator.

Well I guess it is a bit large.

I want my next one to be in the scale closer to "The Tiny" I want one that runs on breath. Im guessing good size ports and bore and a shorter stroke.

I have to design around the size of my tooling. My smallest drill is 1/16", I have no small taps and dies. (I can borrow some from my brother)

My next one will be very small.

FWIW, Tiny might be a little small for a breath-operated engine. Mine takes quite a bit of air to buzz along. Dave Goodfellow has some lung engines that are kinda midway in size.

I agree with shred. My tiny takes more air then the mine eng.
