Default Cogsy's Rupnow Vertical

I'm finally calling my Rupnow Vertical finished so I thought I'd make a rare post (for me) in the Finished projects area. I abandoned the idea of mounting a fan for now and I still have to attach some rubber feet to the base but otherwise it's complete.

Here's some pictures of how it turned out, plus a video of it running pretty well now. At about the 1:45 mark I hand start it for the first time ever and it idles super slowly for me. As I suspected it is quite a well balanced engine and the vibration you can hear is mainly because of the 1/4" table top with virtually no supports flapping about. With some rubber feet and a sturdy table I think it'll happily sit in one place and run all day long.










Now for a big long wait til I can get back to my shed

The moving around on table can be almost eliminated and engine more interesting to watch by a simple modification .I think Brian Rupnows design leaves room enough to do it.
If interested give me mass and dimension of piston and conrod or a link to where I can see the plans.

I don't have the mass of the piston or conrod. The conrod would be reasonably close to the plan size but the piston is made from aluminium rather than cast iron that the plans state, plus the grooves are completely different to plan as I used cast iron rings rather than the single o-ring as designed. Really though, it takes very little to hold the engine in place, even on this flimsy table (it's a weird folding table with the top folding in half and has massive overhang of the legs when set up, plus on 1/4" pine to boot). I'll source some rubber feet and then I'd guess it'll stop moving entirely.

The plans can be found in Brians' build thread, post #136 LINK.
