So I noticed my fly cutter wasn't leaving trailing marks in a work piece today (left to right), and decided to tram it up. No problem, straight now. It's common enough in the HF mill to have to do that periodically.
But what I couldn't take out was the 9 thou high in the front. This was using a dial indicator with .001 graduations held in a collet in the quill, with about a 2.5" radius sweep. I can't tell you 100% that it was ever straight front to back, because I never had a flat plate big enough to sweep it until recently... I think I had just been checking the side-to-side up til now. So I started by taking the Head off, down to the 90 degree bracket that holds the base to the Y axis, and stoning those mating surfaces. Re-assembled and.... still 9 thou out.
So from what I'm reading, the two things I need to do are:
1) Ensure the quill is in line with the Y axis, which I have NO idea how to do effectively, except that it has something to do with a drill rod. Tips/links anyone?
2) Add shim stock or aluminum foil repeatedly between the L bracket and the base until my dial indicator smiles, which could involve taking the entire Y axis loose many times.
Dear God someone please offer tips, other than buying a Bridgeport, as this little X2 is all I can swing for my hobbying. Thanks in advance.
