I recently acquired a Bridgeport mill just like a bazillion other guys out there have and it needs lots of work.

It was appealing because:
- Price was right
- Chrome ways
- CNC servos and mechanisms on all 3 axes
- Ball screws on all 3 axes (yes, including the Z)
- I was naive enough to think I could slap a little paint on it, update the electronics and be running inside a month

CNC stuff had been removed (but I have it) intend to reattach it with new electronics, etc. Whether I stay with the old servos or change to steppers is still up in the air. For me, there are pros and cons of each and I will decide later.

Hurco converted this Bridgeport Series I, 2J mill to CNC back in 1978.

Here are some early photos of the machine before I purchased it

Yes, it is ugly and needs some real cleaning, priming and painting.....but first, getting the mechanicals in order.

This is AFTER we took it to the car wash and spent $20 on quarters getting the years of "neglect" washed off of it.
