Agree shorter is better, I am going to shorten it. But that isn’t causing my problem at the moment only when I want to cut at full z reach. I’m running these at at less than 2 inch and there is no flea on the bit there. As for the middle, I did follow the instructions when I rebuilt 2 days ago and that seems to have caused my problem I’m having now. Squared it with the z assembly in place. Looks like I have a middle assembly rebuild in my future. Thanks for all the help. I’m gone for 9 days now, so will be done as soon as I’m home.
