Crank case, with tapped cylinder mounting holes
I was able to bore the cylinder holes with the tool I made. It cut very well after a little more grinding, and dropping the spindle down to the slowest speed!

Center drilling bearing case attachment holes
Note the use of a center drill in a collet. There was not enough clearance to do this with a drill chuck
