I've had this problem for the year and a half that I've had my PM-1000 saw and am interested in seeing if others experience it as well, and if so, how you deal with it... Seeing as powermatic uses the same UHMW material on all of their fences, I cannot be the only one?
Basically, the plastic warps pretty significantly not only where the t-bolts hold it to the fence, but especially on the front and back ends. I've included some pictures that are hopefully good enough to see what is going on. When holding a straight edge to the fence, there is an easy 1/16" gap in the middle. This ends up causing lots of problems first of all when measuring, as its hard to adjust the fence and accurately measure from the blade when the plastic wobbles in and out across its entire length, but also when pushing longer stock through the saw as the end of the fence pushes the material into the riving knife and blade. It does seem to be more prevalent in the colder months (unheated shop, 40-50 degrees F).
for a high-end saw, I am finding this very frustrating and pretty unacceptable. Does anyone else experience this? Have you found a solution? Yes, I've tried adjusting the t-nut tension.. No help there.
