Also check you jig to make sure it isn't bowed. A Destaco clamp can
exert a lot of pressure and may be flexing the jig.


Good point ... "clamping pressure" on the jig may certainly be a
contributing factor that would be easy to overlook providing that the
clamping pressure, on subsequent taper cuts, is applied to the previously
cut taper on the leg.

However, if the clamp is on a part of the leg that remains square, and, if
the leg is indeed square, as the OP states he verified, then the pressure
exerted by any clamp on the jig should be the same for both the cuts that
work, and those that don't.


I think it could also be a matter of where the clamp sits on the stock
in relation to the centerline of the piece. Once the first taper is cut
and flipped over the clamp may be causing the stock to rotate slightly.
