The saw is a horizontal band saw using a 3/4 blade. The problem is new
and is not related to blade pitch or to a particular blade. When
sawing 5" diameter aluminum the cut is square for about a third of the
cut and then the cut becomes concave for a little more than a third,
and finally the cut straightens out. The roller saw guides are
adjusted properly and the saw cuts square otherwise. The concavity is
about 1/16 inch. Anybody seen this before?
Thanks,
Eric
