I am ripping poplar on my TS (old Craftsman ) with a Freud full kerf rip blade LM72. About 2 feet into the board the blade starts to wobble like it is loose. The blade is fairly sharp. I do not think it is the bearings in the saw has I have been cutting plywood with another blade with no trouble.
I sure would appreciate any trouble shooting suggestions (besides replacing the Craftsman, not in the budget )
