Hi I've had a PM66 for a couple months now and it has a tendency to be 'grabby' when ripping stock, more so with thicker HWs. I've done all the blade, miter slot, rip fence and run out alignments and checked and rechecked. Tried different rip fence toe out settings etc get better results but still not real smooth. Last nite I noticed I could grab and lift the bearing arm a little. With the raising wheel lock not tightened I could raise the arm assembly ~40 thousandths, with the lock tightened then I could raise it 'only' 20 thousandths. Seams like this could explain the grabby cut if the blade is vibrating up and down. Does this sound like a problem. BTW no play in the tilting mechanism I could detect
I talked to their tech support and he went from saying they will always be a little play to umm I think that could be adjusted with a collar on the raising shaft .. then to call me and let me know what you find out
Does the tightening knob just lock the adjustment wheel in place or should it cause the worm gear and lift gear threads to pull together? Seams like there shouldn't be any vertical movement when tightened I'm going to try and adjust so they pull together if that doesn't do it I'll take another run at the tech support Any opinions or insight to this? Thanks for reading Joe
