Yo.
I've recently got this (pictured) milling machine going, it's a Bridgeport industrial mill... very big and powerful... used to make
these:

anyway, I wanted to possibly covert this thing to CNC... It already has a Servo-powered X asis (you push a lever in one direction or another)... doing the Z axis is gonna be hard though.. it sticks out diagonally below the Y axis handle...
Anyway, what equipment would I need for it? (how big of motors, etC)
