That cut joint doesn't have to be perfect.

amuller wrote:Interesting discussion. I'd say you want a little "crush" on the OD of the inserts to keep them in place and encourage them to stay round. is your lathe big enough that you could bore the rods with the inserts in place and the caps torqued down? Or do you have access to a Sunnen rod hone or an expansion reamer?
