I have an old, well over-used 4x6. The blade jumps more now than it

wear on my saw, if the blade is sharp and the feed rate is correct, it
cuts a straight line.

Mine never cut square when it was new out of the box, then I replaced the
cheap guide bearings with good ones (size 6200 2RS), and wow, this thing
cuts a 2.5 inch bar so square with a sharp blade, that the out-of-square
is
inside the "nap" of the cut.

Interesting fix; it's good to know of another mode to watch for these saws
to cut out of square. From the 4x6 group over on yahoo, some have noticed
that this can also be caused by the pivot rod (bed to bladewheel assembly
hinge) holes being improperly positioned.
