After watching tubalcaine's U tube video. I decided to make a lathe test bar , I followed his method to the letter ,buying a 400mm length of ground 3/4" stainless bar . After checking the bar on the carbatec granite plate, I accurately centred the bar each end and it turned out quite OK .
using the Verdict dti along the 400 bar between centres , The initial test on my old Sheraton showed the tailstock off set ( I did this adjustment some time ago) to be spot on :2tsup:
Moving the dti along the top of the bar 400mm , the bar drops .015" down to the tailstock :o
Bringing the tailstock up the the headstock where a centre is held in the 4 jaw chuck, I can see the tailstock centre is noticeably lower . Shims needed I think MIKE
