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.
