Yeah, I kinda resigned myself to making most of it new and ordered all the parts (I think!) from McMaster and VXB bearings. Then I was watching the phase 2 videos and find the first thing he says on the X-axis video is that the phase 2 parts would work, and the phase 1 motor mount I made is the same in phase 2. After looking at lots of prints, I think I'm going to make new phase 3 hardware. But if you're a hobby machinist, there's nothing bad that can come from machining extra parts. I just won't have the Griz done and running quite as soon as I wanted.
