With the head mounted back on the mill column, it's time to reinstall the motor and control boxes. The control boxes on these mills vary quite a bit and mine are modified so your installation will be different. My motor is 3 phase so if you have a 1 phase motor, your connections will be different.
Reinstall my speed, direction and tachometer control box.
Reinsert the motor key and carefully align it with the motor shaft on the top of the head.
Bolt the motor down and reconnect the wires. For three phase, they need to be in the same order as they came off otherwise the motor may turn in the wrong direction.
This is the control box for my Z Axis power feed.
After reinstalling my control boxes I was able to power up the mill and test the motor and gearbox. I sounds good, all speeds work, and no leaks. I am relieved.
