View Full Version : My Version of Elmer's Mine Engine

Been a busy spring and this model took me awhile, but it turned out OK
Elmer Verburg's plans are to credit for that.
It's a great slow speed runner! A short video of it running can be seen here:

Nice work! Also, it's always interesting for we engine folks to see an unusual species now and then.

Keep up the good work,

On that video the flywheel appears to be pausing with each stroke. Is that just an optical illusion?

Actually it runs pretty smooth even at slow speed.
I'm having a tough time getting a video that shows that.
I have this one, Mine Engine Slow (http://www.rake60.com/photogallery/Mine_Engine_Slow.mpeg), but I'm not sure it shows it any better.
Maybe my wife should get a better camera for her birthday this year.
Of course it would be just for HER! ;)

Rick, looks like very nice work. I think the second video does show it off better. How long did it take? Yeah, I know, its just a hobby and no one keeps track! :)

I have noticed all of my projects take exactly 850 percent of the time I estimated when I started. :D

I think I had about two weeks in it all together.
A few of the parts were, well, made more than once.
The cylinder bore for instance is offset .030 from center of the 1" square stock that it's made from. I noticed that little line on the print about 3/4 of the way through making it the first time. The pins in the valve levers are .060" with .040" holes through them for lacing wire. A couple of them were done twice. But when you don't have a cranky inspector standing there saying "What Were You Thinking?", it doesn't matter!
