The updated parts are a bit different. 1 piece in the middle vs 2, so far. Printing up the new design tonight.
I hoped there would not be a stack up error. The rollers should lock the conduit in square. Then the middle assembly should actually be tightened down while the rollers hold it all square. The machine I built last week has been running on hand tightened parts in the middle assembly and it is actually the most square machine I have put together yet. I am getting the feeling people are severely over tightening this thing. I am using large bolt because they fit the bearing diameters. Most people are seeing these big bolts and getting out there ratchets and cracking parts, miss-aligning things by actually crushing them out of square.
