Default Can anyone explain this?!

Yeah, right . . . . a brand new fence is warped . . . . (as I run out
to the garage to check).

Well, the fence is flat . . . unless the height adjustment butterfly
knobs are snugged up . . . then the fence deflects at the knob
locations . . . . about the same offset I am seeing on the boards. The
Dewalt 746 has 3 knobs to lock down the height of the fence (1 at each
end and 1 in the middle). Each of the knobs exhibits the deflection
behavoir. If the knobs are just barely snug, no problem . . . another
half turn and deflection occurs. Apparently I had the center knob
tightened more than the outer ones.

Can't wait to rip some wood to see if this is the root cause.

Great suggestion.

Let us know ASAP if this was the problem. I wanna make sure physics and
geometry still work OK, or if we need to turn in a problem report.
