I have a Bridgeport Series 1 mill which I purchased new in 1974? (#172.064).? I later swapped the head for a 2J (#39231).? It has been inactive and in climate controlled storage for the past 20 years.? I am retired now and am re-activating this hobby machine.? LPS rust preventative was effective but challenging to remove.? All appears to be functioning as intended with the exception of the quill.? The quill is stuck in the up position.? It is possible that the previous quill lubricant has dried out causing the problem. About ?¡± of quill is exposed and lubricant had turned to a varnish like coating which I removed by applying solvent.
?
I took out the quill clockspring to expose the pinion but that was not enough.? How should I proceed to resolve this?? Will removal of the motor and head expose the quill and rack and pinion such that some loosening solvent can be applied?
