Yeah jon I found it- oct 99 page 40.

It seems the tester had problems with chatter and excessive vibration.
Also the push in force was 50 lb.

The unit worked ok only for very small short bits.

As far as a turning spindle for the mill bed I was thinking of building one
up from some taper roller bearings. Mabye a spindle bore of 2" or something
like that. It's rotation could be open loop. Even with only 3 axes you could
put a single point tool horizontal, another pointing opposite and upside down,
and a third pointing down. So you could get at least 3 turning tools on
the Z with very little fuss. Just move x,y,and z to get the selected tool in
position. Get it?
