I've recently noticed the blade that came with my TS2424 is slightly concave (dished) on the left side (pulley side when blade is installed). I became aware of the concavity when I started making cuts with it. Although the blade is set perpendicular to the table surface using a square against middle of the blade's protruding disk, the cut ends up off perpendicular by what I estimate to be 0.5 degrees. What is happening is the blade's teeth are not travelling in exactly the plane formed by the blade's protruding disk. The concavity is perceptible when a straight edge is placed across the middle of the blade. The maximum deviation looks to be about a 1/64". Can this problem be corrected with blade stiffeners or should this blade really be replaced? The blade is the 10" Ridgid 40-tooth carbide combination blade with the feed/chip limiting profile. Looks identical to the Sears C200 combination. In addition, the table saw was a demonstrator at Home Depot before I purchased it, could improper cutting by sales staff do this to the blade? Would this void the Ridgid warranty on the blade?
