The OP seems to be unaware of the radial loading involved. I have a drill
press and a milling machine among other bits and pieces and the the
difference in the bearings between the two is staggering. Whilst I could
easily clasp the drill press bearings in the palm of one hand, I couldn't
even get both hands around the mill bearings; they're *massive* ****ers.


I, the OP, am unaware of many things hence the thread. But is the radial loading that bad with a scissors knurler? It would obviously be ridiculous to use a side knurler and push it onto the piece - the radial pressure would be far too much as above. But a scissors knurler, if the piece were held top and bottom?
