Awl--

My compadre's new-er Kalamazoo horz'l band saw (I got the old one) is
dishing--ie, the mat'l in the vise, after a cut, has a low point in the
middle. On 3" diam alum, about .030; the bigger the diameter of the piece,
the more the dish.
What could be causing this? Aside from the dishing, the pieces are square,
the blade is tight (1", .030), he says the feed/speeds are right (proly
conservative), teeth count OK, plenty of coolant..

Iny idears?
