Next issue in the PDM-30 saga. I finally decided to use it the way it is and just face a piece of scrap mild steel. I haven't bothered to tram it yet, just want to see how it cuts with the existing vibration.
Now I discover there is 0.030" backlash in the spindle (z axis). Holy crap that's a lot!! The owners manual has no information about adjusting that. Is this normal for these round column mill drills. I've read a few threads about people creating / having a fix which involves keeping down or up feed pressure on the quill to resolve this but can't find any posts indicating what amount of backlash they started with. If it's normal then I will just have to develop a method to deal with it or implement one of the solutions others have created.
