Clamp Type Knurling Tool

[TomG]

Rob,

I just run the knurls against the work finger tight, snug up the lock screws and add about 1/8 turn additional pressure (less for finer knurls). It works so well that adding the extra complexity of a self centering feature wouldn't really be worthwhile. Besides, there is enough backlash in the cross slide screw to allow the tool to float, so it already self centers.
