I'm just starting to plan the cnc conversion of my mill (Myford VMC)
I made some static measurements on the torque needed to move the X axis
feedscrew and this comes out to about 1.25NM (or 176 oz-in).
It seems that motors are specified by their holding current on the data

Can anyone point me to an illustration of a MEC BROWN cut off saw
fitted with the left hand bar support. It's missing on mine, there

Real tech or April 1?

I've got a chunk of round aluminium bar of 60mm diameter, 100mm long.
I want to bore this out to make a cup shape with 5mm walls (so
removing a cylinder 95mm long by 50mm diameter). I have bought a
Glanze indexable boring bar (from RDGTools or Chronos, can't remember

A mate of mine has asked me to take a look at a manual bridgeport mill
(I don't know which model) because neither the X or Y feed motors seem
to be working. I'm guessing that it is unlikely that both motors will
have packed up and it is possibly a supply problem. Spindle motor ...
