As well as dealing with the Sierra's I also ran in to a problem with my 9" band saw. It worked fine for about 15 minutes ( and has done since I bought it 2 months ago)and then made a sort of screech! Then immediately started to cut at an extreme right curved cut. I took the blade off, adjusted the guides a bit, cleaned out the dust, put it back together, checked the tracking.....and it is still cutting a sharp right curve. It doesn't even cut straight for 1/8" just enters the wood and does a right.

I really need to get wood cut for a trade tomorrow ---and I can't use my floor standing 14" because.......................because I was cutting a section of arbutus (Madrone) and the blade closed around it. I have tried everything possible to release the blade from the wood, even decided to sacrifice the blade but still can't get it out of the wood. So it sits there, laughing at me, still stuck but now with a chisel stuck in it!!! I thought I could use a chisel to open up the line of the cut and reduce pressure on the blade......no such luck.

But my main need right now is the 9".

Any ideas would be greatefully appreciated. And don't tell me to throw it out, that's not an option.

Thanks.

Ruth Have you tryed a new blade? Are your tire's on the wheel's right,one could have a bad place in the rubber. check for somthing under the tire. Hope you get your saw running. On the 14" just break the blade and replace it.
 
Ruth,
Do you have another blade to try?
If the blade hit something and took the set off of all the teeth on only one side of the blade it will do what you described. I have seen this happen when the blade gets funky in the guides and all the teeth on one side rub on the metal frame from the guides or somewhere else hitting metal. That would explain the screech also.

Another thought if this happened while you were cutting is that there could be a piece of metal in that wood. Check carefully.
 
Couple confusing things in your post.
e.g. You said, in part, " I took the blade off, adjusted the guides a bit..." How did you adjust the guides with the blade off?
And, "..the blade closed around it.." How did the blade close around the wood? I can't visualize that unless the blade came off the wheel or broke.
However, as others have said, a new blade seems in order, especially if the current one has been subjected extreme twists and bends.
 
IHMO, you hit the teeth against the blade guide. Are they roller or steel block? I did just this to a small blade when my Walker Turner saw has steel guides. Took all but a second without the thrust bearing moved up to ruin a 115" blade. That was when I went to Ligum Vitae for guides and I have never looked back.

A "sharp right turn after a screech" tells me that you hit steel and you blade is gone.
