Because they require much more power than hand-driven lathes, the introduction of milling machines had to wait for the invention of industrial water and steam power.

I called the Lubriplate folks quite some time back for clarification. As soon as I mentioned 107, the guy said "you must have a Bridgeport mill". Turns out the 107 was a misprint on the lubrication plate on Bridgeport mills as #107 never existed. 105 is sold as motor assembly lube. You can just squirt it in through the hole with the big tube.Web

Assuming it's a 3-phase motor, just swapping any two power wires to the motor will reverse the rotation. The spindle can run in both directions. Choosing high or low switch accomplishes that. Since this is a 3 phase device, swapping 2 wires will change direction. This is important because when tapping G84 (with a floating tap holder) the ...Web

IIRC, it threads into the brake band ...Web

The Bridgeport leadscrew has a pitch of 1/5" so someone better at maths than me would have to work out all the gear ratios required to to give the required helix angle.
