:>-Jim :I bought one of these saws, a JET one, 23 years ago. They are all the :same though. Mine did the same as yours. I took it back and was told :it was the blade. Well, the blade was ruined because the saw wasn't :cutting correctly. With the blade set 90 degrees to the base, as it :should be, the blade would move in as the saw went down. So, the :problem on mine was the pivot pin holes were not bored parallel to the :saw base. You can check yours for this problem. Clamp a square to the :saw base. With the saw all the way down measure from the blade to the :square. Then raise the saw two inches and check again. This will show :if the pivot is wrong. You should get about the same error as the cuts :are turning out.
I had that same problem with my Harbor Freight model. I had to bore out the pivot hole on one side of the base and insert a sleeve to bring the properly aligned, but oversized, hole down to size. That saw base looked pretty ridiculous clamped to the table of my little Clausing 8520 mill.
