I need some advice. I bought a J-head bridgeport a few weeks ago. It had been used in a plastics company previously for a dedicated operation. They had a rotary table on it and just put the part on the table, cranked the knee up and took their cuts by rotating the rotary table. The X,Y, and Quill were all locked in place. I obviously want to use it as a normal mill. I was able to free up the X and Y axis by cleaning out all of the junk accumulated on the lead screws and ways but am having a problem with the quill. It is stiff to move up and down almost like the quill lock is engaged. It gets stiffer as the quill travels down. I loosened the quill lock and tapped on it with a drift but it didn't seem to make a difference. I'm not sure where to go from here as I have never disassembled a j-head before. Is there a way to pump oil through the quill to try and flush it out? What is involved with removing the quill?
