Thanks for the post, Dave. I just purchased a used 8" jointer, and
removed the infeed table for transport (and weight reduction). I'll be
cleaning up the ways and gibs before reattaching (may or may not remove
the outfeed table ...)

I was doing some edge jointing on my router table a month or so ago was
getting this same behaviour - wedge shape forming. Turns out the two
faces of my fence weren't perfectly coplaner because there was the
slightest bit of schmutz (sp?) on the shim stock for the outfeed fence
face.

Regards,
Chris
