Topic tags/keywords: bandsaw question

I feel stupid writing this but my bandsaw has eaten 2 blades in the past month and I’m trying to find a solution.

I have a Laguna 14/12. It’s eaten two 3/4 in resaw blades in the last month. I installed a new 5/8 in blade tonight and noticed that the blade is running nicely on the crown of the top wheel but on the bottom wheel it rides forward on the wheel about 1/16 in from where it runs on the top wheel. Is my problem co-planer wheels or am I chasing ghosts? If it is a co-planer problem how do I fix it? Please help, this is getting expensive to chase down.

What does “eaten” mean? What kind of blades were they. Is this a new problem that you didn’t have before? Have you ask Laguna Tools for ideas? Good details will help you get good answers.

When I had a 14’’ band saw any blades over 1/2’’ didn’t seem to work as well as 1/2 and under.

By eaten I mean the blade comes off the wheel when making a very ordinary cut and works itself into the upper wheel compartment. My blade tension is good to go, my blades guides are set just behind the blade gullets and roughly .001 away from the blade. I’ve only had this problem with larger blades but the 14-12 should be able to handle them without issue.

Oh, and they were Timberwolf blades. I switched to a cheaper Starret blade hoping the different manufacturer might help. I’m trying to get some guidance before I wreck this blade as well.

Don’t worry about coplanar unless it rubs on something it’s not supposed to.

When you make a cut it should force it into the guides? I’m confused about how it is coming off.

I don’t know either. It happens very quickly, the blade jumps and gets hemmed up in the upper wheel compartment.

Of course, you cannot have a bandsaw thread without mentioning the Alex Snodgrass video. I do not have the link but should be easy to find and the best video for aligning bandsaw blades.

There is a tracking adjustment on the bandsaws, based on your projects i am sure you have adjusted it. However it may have some ‘play’ in it. Try moving the wheel ( like you would to test automotive ball joints) to see if there is some play. Just dont test it as hard as you would a ball joint.
Just my thought, based on the description

Not that I have the answer but….is this a new problem or have you always had this problem? Is this a new saw or used one. Have you asked the seller of the saw what they might know about the problem?

The Wood Whisper Channel has a new video he did for Marc, it’s worth a look as it’s really well done.

I’ve seen a few people mention this around the internet, so it may be a known issue.

My guess is the tires are rolling up and tossing the blade off the wheel. I had this problem once with my 14 pm bandsaw. It has the tires that are not glued down.
I kinda remember trying to use a .035 blade with too much tension

From what I just read on the internet I’d say there a good chance that could be the problem

It would be interesting to know if this is a new problem or a long on going problem but I guess he not willing to answer that question.

This is a new problem, the bandsaw is only about 1 1/2 years old. I’ve inspected the tires and there’s no issue.

Have you talked to Laguna. I have found them very helpful – once they got done laughing at my predicament. I deserved it.

Just a thought…on the Delta’s there seems to be tendency for the lower pulley to loosen and start walking off the shaft (your co-planar question).
