Same thing happened to mine. Found two things: it was imperative to use the best quality cabinet quality blade possible. Something that's thin, heat controlled and SHARP. THe second was to square away the saw blade angles. Found the kerf was fuzzy to one side. THat got me to thinkin'...Tape helped, but only to a point. Found the blade was not exactly parallel with the arm. It was almost to the micro adjustment stage, but kept at it to align and square the arm with the fence, the table perpendicular to the post travel, and most importantly to keep the blade parallel with the arm travel. Finally got it dialed in and was pleased with it. Also had to use a VERY slow feed rate when cutting bevels as the blade had a tendancy to climb and consequently alter the otherwise straight line. This was using a vintage Ward's 10" from about the late 60's.
