I think you may be having a BLADE problem. If the blade is tracking to one side it may have lost it's set on one side. Did you accidently hit a nail or something hard that took the set off one side? Did you run the blade blocks into the blade itself. If the blade is tracking on the wheels and all else is adjusted Ok, it is usually the blade itself. Before you give up, check the set on the blade, it should be equal on each side of the blade. Also be sure the tension is correct on the wheels.
If all fails - send it ton Numbskull - he can use it for his awsome curves......
