Long story short I've gone through my RF-45 head to toe and now that it's all back together I'm still having the same issue with my quill. It has a spot about 1/3rd of the way down (extending toward the table) where it gets so tight I really have to put some muscle on the handle to get it past. I blued the quill itself and I can tell where it's rubbing (or worse grinding) and for the life of me I can't tell what is causing the rub. Does anybody know of any machinery repair company's around the Dallas area? Or someone who is experienced with milling machines and/or mill drills (preferably local and can come see it in person). I'm about to pull my hair out, any help is very much appreciated!!
