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

Machinging the bearing case
I used 2" square aluminum for the bearing case to prevent waste, so it came out about .1" undersize, but it's not critical

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!

Boring the crank case
My boring head doesn't give enough clearance to finish the holes, to 5/8", so I made this 4-flute countersink-like tool. It cut down a bit before stopping. I think I'll use it on all five, and open up the clearance for the piston rods with a small endmill

Boring the 5/8" cylinder holes
I only have fixed tools up to 1/2". Due to clearance problems, I am finishing the hole to .500 with my shortened ball end mill. Not the best way!
