I bought a Delta 6" open stand jointer 2nd hand last year, and i just recently was trying to use it and was'nt getting the results i wanted. After evening up the infeed and outfed tables,and putting a straight edge on it, it turns out the infeed slopes down toward the cutter(not parallel):thumbup:. The infeed adjusts on a dove tailed track and i don't see any way of raising the cutter head end of the table. It just slides up and down hill on the guides. Any tips from the veteran shop owners would be Fantastic!
