One other thing. All the parts are being drawn as shown in the original plans, with as little deviation as possible. But, some of them (the flywheel comes to mind) are rather plain. I'd really like to see some personal touches added, as long as they won't affect the fits or operation.
Anyone making stuff that would like to add some minor flourishes should probably ask if they aren't certain, but this engine is quite plain as made, and there are lots of possibilities to dress it up a bit. Personally, I intend to do some further machining on some of the parts just to add visual appeal.
