Hello,

looks fine.

How will you lubricate them? What about 2RS ball bearings?

Hi Dietrich, thanks for commenting!

The inner bearing here is inside the crankcase (oiled). The outer bearing, not yet installed, will be a 2RS. Next step is shortening the tubular part of the housing to finished length, and then boring the outer bearing recess. The tubular part was left long for easy chucking up to this point.

I like your engine very much!
