Thanks Guys,
Dean, sorry to say they need flats to fit in the block. Before I do that I have to de-burr the fins. The old eye balls didn't pick up on the burrs, the camera sure did. I'm going to use a triangle file and turn the cyl in the lathe to clean them up.
Jeff, I slowed a little. I bought another Kool Mist for the lathe. I liked it so much on the mill and it was a pain to move back and forth. So, I was bizzy running air over and hidding hoses behind walls. I got tired of tripping over them.
Tony
