My bandsaw has taken on a strange issue. As it runs, the blade periodically jumps forward in the direction of the teeth. I'd say about every half second or so. Apart from making a raket it also is really hard to cut with, and I'm concerned there are only about five teeth actually doing any cutting.
What's weird is I really don't see anything out of alignment. All the guide bearings look rightt, blade is tracking on the wheels straight. Don't feel excessive crud build-up on the wheels.
I just don't know what else to try. Everything seems according to the book, but the problem remains.
Sounds like the blade was not welded correctly. The two ends of the blade at the joint are not aligned. If it is indeed the blade, it will cause damage to the guides.
OP didn't say what size blade he was using. I think some of the wider blades are designed to do exactly what he is describing (e.g. I experience it when I use a 3/4" blade for resawing). I think the goal is to widen the kerf and give a little longer life to the blade. For finer work, I switch to a 3/8" or 1/4" blade and I don't notice it there at all. I'm not a bandsaw expert at all, just relating my personal observations.
Several people nailed it though. I took the blade off and inspected it closer. There was a crack about 2/3 the way through. No doubt it would've popped soon.
teejk If you are experiencing the same problem you either have a bad or poor weld. the set in the teeth is there to give a wider kerf and clearance for the rest of the blade. With a good blade and proper weld you might here a little tick when the blade goes by the guides but that is all.
