Bearings all finally removed and replaced. I took this opportunity to clean and paint the mill. looks great. I also wanted to replace the knobs on the quill feed. The original knobs had no insert and kept getting loose and falling off.
Has anyone replaced these and can tell me what size thread they are? Tried M12 x 1.75mm and 1/2"X 13
