A Heavy 10 in the same category as a Monarch, give me a break. You can do excellent chambering work on them with the sleeved headstock bushings adjusted properly. Tell me what bed wear has to do with chambering accuracy? When you turn a tenon you are only using about 1" of travel and the same in threading? 99% of folks use the tailstock to push a floating or pusher style reamer holder and bed wear has no effect on this.
Butch, stop making so much sense, buddy.
Hope you're doing well, my friend.
