[Bill C]

Hello,

Sure was hoping for more activity here towards IC engines. I would enjoy seeing other's accomplishments since mine are at an all time low after starting on a mill-NC conversion. I had limited myself to one and two cylinder engines due to my total anguish of any sort of production part making; the NC should help with that!

I've attached (attempted) a photo of my favorite engine. This engine turned out so well that I use it as a test bed for carburators for other engines. This is before it was installed on a stand.

Thanks,
Bill C.

Wow:

Fantastic!!
I am at the limits of my ability keeping my lawn mower B&S running, never mind building a working IC engine from scratch.
I, too, am disappointed in the volume of activity here. I would like to see other peoples work as motivation and inspiration for my own feeble attempts.

robotic regards,

Tom

Not many in the I.C comunity know about the site, thanks for your support.

Here is a photo of an engine I started making this winter. Its called the MAVERICK ENGINE. Has a .750 bore and a 1 inch stroke. Still need to make the busy side of the engine. Valves, carb, ect..

Here is a picture of some of the parts. Crank, bushings, cyclinder, sleeve, etc..

THe peice of steel on the middle is what I start with. and the end results is the crank at the bottom of the page. Its pretty neat watching it take shape.

I think it's cool what you guys are doing. I have a question for you Bill, Do you not need a counterweight on that crank to reduce engine vibration like full size engines?

I hope this forum picks up. It's a very interesting subject.

Balsaman,

The picture of the crankshaft is not mine. That type engine is slow turning so the flywheels usually carry the counterweights for engine balance.

I'm happy with what I see; I'm eager to keep some interest going here among us for these interesting engines. Please let me know if I can be of assistance to any of you - glad to help.

I have other engines that I will send photos for... The 'hit and miss' engine that I'm working toward is a Red Wing and have a photo or two to send along. I keep buying engine casting sets hoping that some day I can take the time to complete them...

Bill, sorry, yes, I think Woodnack's name is "William"...?? That's who I was asking anyways..

Balsaman,
Ya what Bill. C said. The engine should only be turning around 400 or 500 rpm. I am going to drill holes in my fly wheel too. Its still kind of heavy. Its made out Nickle Copper. More Nickle then Copper. Really sucky stuff to machine, Very hard! This is my first IC engine. And what I am learning is that it takes a very long time to machine each part! I guesss thats what makes it fun. I have put the project up till next winter when I have more time to spend on it...

Look at Balsamans pictures.....

Nice Engine!

This really isn't the place for 'MICE" as its called. Most of us like to do it all by hand, so the CNC forum isn't that much of a fit. As time progresses, I'm sure making this stuff with CNC will be ever more popular if a little less romantic. There are several other Yahoo forums (4) that all have good stuff already, though not CNC focused. If we posted and shared our 3d models and CNC stuff here, it would be a useful addition, but otherwise the other forums are already available... Just my .02
