I am wondering the same thing about the head being bent, as I have used
shorter boards that were flat on
both sides and it still occurred. That is why I tried a longer board after
I had rechecked
the tables and waxed them.
I guess it will take a dial indicator to check the head or would you be able
to see it with a straight edge?

I'm having a problem with the cutters creating a low spot or dish in the
center of the boards.
I have rechecked the tables to be sure they are flat and level. Recently
I installed new knives,
they didn't help. Any ideas what is causing this?

Thanks in advance for your help,


Have you checked the cutting head relative to the table? In other words,
are the knives parallel with respect to the table? Did you tighten the
bolts consistently across the blades? A 1/4" torque wrench should help.
The cutter head maybe bend or the cutter head end bearings maybe out of
round.
