Got things trammed in and managed to make my first cuts, taking the keys for the t-slots down on my Shars 5" vise. The tramming issue turned out to be insufficient deburring, of both my and Grizzly's work. I'd gotten a new deburring tool since I put the mill together last, so it was a good chance to use it and clean up my ball screw hole and the column bolt holes, with a bit of paint scrapping for good measure. Tramming was still fiddly, but it seemed more consistent this go around. I found that the gib, and or locks on the gibs tension was important to get the alignment just right.
