<DIV><FONT face=Arial>I'm pretty sure its blade alignment - or at =
least that is
contributing to the problem. The alignment dohickeys provided with the =
machine
are total junk - they don't want to sit in any particular spot, thus =
allowing
the blade to wonder anywhere it wants. I know that is a problem, so I =
figure fix
that first and then see how it works - if I need to pursue other items =
at that
point, so be it. Thanks for the thoughts though.</FONT></DIV>
