OK - I got a few hours over the weekend to work on the mill. First job was to replace the bearings in the motor, which was a simple task. Whilst the motor was in bits, I clamped the base to the table of the shaper and made a flat where the motor lock fits. For some reason, this part was all mangled but the shaper made quick work of that. I borrowed a length of .750 brass hex from a friend and made a new bush for the locking mechanism. I also made a stopper to keep crap out of the oil port for the back gears.
I got the feed gears installed and the worm gear assembly. I put the quill back in, set the spring and then put the backgear assembly on. Next was the belt housing and finally the motor. This was followed by wiring the motor back up (yes, I just noticed the switch is on upside down!) and flicking the switch. Thankfully there was no bang, nor did any of the magic smoke escape.
So, having got the bare minimum done to get to this point, I pressed the start button and was greeted by a much nicer and much quieter sound that I had immediately prior to commencing the tear down. I then engaged the back gear and all was good.
Next to go on was the feed trip bracket and plunger, and then the clutch. I was all ready to test the quill feed when some interesting noises emerged from the contactors in the electronics box and the lights began to flicker. I was soon plunged into darkness and noticed that one of the three neon phase indicators had gone out, indicating that I had lost a phase. A quick check showed that it was the incoming power and nothing I had done. So there wasn't anything to do but power down and call it a day. We just got the third phase back a little while ago. Oh well, I'll have to wait until next weekend to progress any further.
