Chambering reamer chatter - 12/20/09
I need helpful suggestions, answers would be even better.
I am chambering a barrel to 280 Rem. for a friend. (his barrel and his reamer)
I put it between centers, trued the chamber end and put it in a steady rest. All went well until about .o25 from the go gage fitting and the reamer developed a chatter. I was running the lathe in back gear, 50 RPMs using a heavy cutting oil. The reamer has 6 straight flutes and is held in a floating reamer holder in the tailstock. How do I remove the chatter marks so I can finish the chamber?
