Topic tags/keywords: bandsaw burning

Any ideas how to solve this problem? Bandsaw used to work well, but lately I get burning on one side of the cut only. Changing the blade does not help. The tires on the wheels are fairly new. Nothing seems to wobble or be particularly noisy. It is a pretty good quality Delta saw. Probably 15-20 years old.

Are the guide wheels/blocks out of alignment? They might be rubbing on that side of the blade. That doesn’t really make any sense but I thought I’d give it a shot. If mine were doing that, I’d assume I was doing something wrong.

I’d suggest looking at the tensioning system. If the tension spring is wearing out, you may be lacking enough blade tension, causing the blade to slightly bow during the cut, and thus burning only one side. See my fiasco with blade tension here.

highlandwoodworking.com has a replacement spring made by Iturra that should work for your saw.
I hope this helps!!

(Newbie here, watch out!) I am just stabbing at air here… Is it a new blade and does it cut straight? Perhaps the tooth set on one side is not correct causing the chips to become trapped on that side only? If it is an older blade do you have rust building up on one side only?

I would be interested to find out what is causing this in case I run into it in the future! =)

It also sounds like you might be fighting against the drift of the blade and the back of the blade is burning the wood.

Thanks for the tips. Been snowed this week so haven’t been able to test much. I did adjust the guide blocks some and did a cut on a small piece freehand and it seemed like it might be better. Real test will be to saw something substantial which I haven’t done yet!
