I moved my Bridgeport to my new shop a couple months back. The new shop had to be completely re-wired and I didn't get the machine back under power until a few days ago. This morning, I tried to tram it in and use it and hit a problem:
The quill is stuck.
Actually, that is an over-simplification. It moves just fine the first inch of its travel, then it stops. It doesn't jam, per se, it is just like it hits a stop. The power downfeed works properly in that first inch, but, when it hits the stop, it won't go any further (this is turning it by hand; obviously I'm not going to do it under power...).
When I moved the mill, I inverted the head to lower the center of gravity and moved it back to its normal position a day or two after the move.
I tried listening to the head in various places with a mechanic's stethescope, but I couldn't here any sharp, metallic sounds when it hit whatever is stopping it.
Anyone else been through this or has anyone overhauled a BP 2J head and can suggest what happened?
