Twin opposed cylinder 1/2A engines?
I was thinking about those twin opposed engines I see here and there. Would it be possible to fuse two engines and just use the same pin for the two conrods? I realize that in an opposed twin this would cause some major vibration, and the firing would be...
gee, I just realized there would be a problem with the firing (guess it wouldn't suck air into the chambers). [
]
Ok then. So let's say we had an opposed cylinder design with a third bearing in the backplate to support it the second cam and pin, how hard would it be to make it work? Would I need to make a new crankcase or can I just buy another crankcase, carefully cut at the right places, and fuse them at the line where the mounting flanges touch the engine mount (on a single engine)?
What other problems might I run into, were I to undertake this sort of project?

Ok cub mentions on [link=http://okengines.com/news.shtml]their site[/link] that they are developing a reed-valve twin.
I wonder how that's coming along.

Who does their marketing? I would think a decent run (no pun...well, maybe pun) of their .049 and .075 diesels might be well accepted. They were light and ran well.
