Hello all, I installed a Byrd Shelix head on my 15 inch Powermatic planer this weekend. When I run a board through the planer makes a squeeling noise like a belt slipping. It does this intermittantly and only when actually planing, not at all when just running. I replaced the belts with a matched set of three and adjusted to Powermatic specs of 1/4 inch deflection. I am 99% sure I have the gearbox together correctly. Infeed outfeed and chip breaker are set at .040 below cutting circle. Has anyone else had this problem or any ideas of what might be wrong. Would appreciate any advice. Thanks
