'Just a quick note. After two years of use, I am very happy with the upgrades I made, especially the drawbar. While inarguably the simplest upgrade, it has made a huge difference in how easy the mill is to use on a constant basis. The hardened cinch nut still looks almost new, while the old cinch nut was so soft its edges rolled over, rounding off the nut. As I mentioned previously, the roll pin actually fell out of the top nut, but since I welded the top nut in place, there is now zero concern of it coming loose. It seems very unlikely I would ever need to replace the cinch nut, but if for some reason I do, cutting off the top nut won't be a big issue. The taller cinch nut makes tightening and loosening the tools in the quill so much easier, it's almost silly.
