Slipping MT2 tailstock

[pontiac428]

I think that when reaming a taper, the use of the center and crescent wrench is the better approach than the collet, but care must be taken th be assured that the center is aligned in a true manner to the other taper.

You're probably right, but on the other hand, there is nothing more self-guiding than a taper. The steel may not be 65 on the Rockwell C, but it ain't butter, either.
