Bandsaw question

(1/2) > >>

DC:
My bandsaw leaves these marks/grooves across a cut. I thought it was one tooth out of set but I've now noticed that it's every blade. I get my blades from a guy down island that cuts and welds them from bulk. I thought that maybe his welder was knocking a tooth out of line or something but I examined all the teeth in the area of the weld and can't see anything wrong. If it is a bent tooth how do I find it? It's only a 64 1/2" blade so it's not hard to examine but I can't see anything. Could something be wrong with the saw itself? Any help would be appreciated.

Pat B:
Bent teeth?

osage outlaw:
Do you have the blade guides set correctly?  It looks like it has too much play.  Maybe the tension isn't high enough?

DC:
It sure looks like it would be bent teeth,Pat, but it's happened with many blades. The saw is a metal bandsaw that I stood up and added a small table to. I'm not sure how adjustable the blade guides are. I'll try more tension, that's an easy one.

PS more tension helped a lot but I had to make it scary tight.

Del the cat:
Could be something on one of the wheels or tyres. Take the blade off and spin the wheels with a bit of sandpaper to clean 'em off and to feel if there is a high spot etc.
Waggle the wheels while you have the blade off to check the bearings.
Failing that, give it all a good strip down and clean ... works for most things.  ;D
