I have the laser center finder from LittleMachineShop.com It has a 3/8" shank so I suppose you could hold it in the tailstock with a collet. It is not that accurate- the center dot is still pretty big- several thous at least. The concentric circles help a little but I think its just a 'very near' tool. If you are doing 4-jaw work of any accuracy a DTI is the best.
