Hi -
I have a 14" closed-base Jet bs (bought a few years ago), cool blocks, no riser. Pulley belt is properly tensioned. I have a 1/2" (6 tpi I think) Suffolk blade. I have no idea how much wood I've cut with the blade but haven't used the saw for a number of months and don't remember if this has been a problem before - very strong burnt wood smell when cutting. Doesn't matter if it's 3" maple, 1" walnut, 3/4" birch ply. I could be wrong but I think I have to be cutting something for at least an inch or so before the burning wood smell starts.
I thought maybe the blade needed a good cleaning so gave it a couple apps of cleaning spray (the stuff you'd use on router bits). Still smell burning wood. I cut no slower than I ever have; tried speeding up some but doesn't seem to help.
So I took it off and put on the blade Jet includes with the saw which I've only used a couple times. Same problem. So I'm guessing it's a feed rate problem but AFAICT I'm cutting no more slowly than I ever have. The Jet blade's tips definitely feel sharper than the Suffolk's (so I don't know if that means it's time to replace the Suffolk). Besides feeding too slow, what else would cause the burning wood smell? Just a dull blade? Or could there be some sort of adjustment problem? Also, is there some visual test for a blade that's worn out (besides no teeth)?
