I’m going to do your suggestions on the all thread and the drill, cut smaller legs, and see how my rigidity is then. I also replaced a middle end today that had apparently developed some kind of wear (it used to have all 3 bearings firmly touching the pipe, but one of the 3 were just barely touching now – maybe it could also have to do with the temperature being in the 90s when I put it together but now in the 50s)
“I actually have a new mount for the dw660 that should make things even more rigid but At the moment requires modifications to the z rails.”
How extensive are the modifications? Is it just drilling some new holes or is it ‘take the middle assembly apart’?
