First, I want to be sure I am not breaking the brand rule as posted in the stickies! My Jefferson mill is older and probably rare. I know of only 3 but I am sure there are more. To continue I have a vertical unit that has been modified by a previous owner that I would like to use on the Jefferson if I am able to complete a modification. Also please Identify the spindle if possible. It uses an MT2 collet. If I get the photo uploaded the overarm support is not part of the conglomeration.
