I’ve used band saw blades on my Craftsman (Rikon Clone) 14” band saw as small as 3/16” up to 3/4” depending on what I’m sawing but I wanted to make some tighter curves is a few plaques I’m making. So I bought a 1/8” Carter band saw blade to accomplish this. I set things up the same way I have set up every other blade but for some reason, I can’t keep the 1/8” blade on the wheels. When I get the blade where it’s supposed to be on the top wheel, it sits at the very front of the bottom wheel and when I am sawing, it comes off. I can get it to stay on for a short time if I’m very careful and saw very slow but if I put any kind of pressure on the blade or begin cutting the curve, it pops off. I thought it was something I was doing wrong and I was having a brain cramp so I put a 1/4” blade on and cut out some circles on some scrap. No problems at all. So then I did the same with a 3/16” blade. No problems with that blade either. So I set up the 1/8” blade again and it almost immediately popped off the wheel when I began cutting. Eventually I gave up and used my scroll saw to cut out my plaques. It was very time consuming but the job got done. I was just wondering if anyone has an idea on what I’m doing or not doing to cause this issue. Thanks!

It could be a number of things; the band tension could be too lax for the blade dims, the side bearings top and bottom or cool blocks could be spread too far. the upper and or lower thrust bearings could be back or forward too far.

If you haven’t done so as of yet see if your BS manufacturer has any guidelines for tensioning. Look up flutter test for BS bands.

How old is the BS, what condition are the tires in?
How high is the guard set?
Is the table square to the band?
Are you pushing too hard and causing the band to deflect?

Take note of the thickness of the materials your cutting and fiber densities. What a 1/4 and 3/16” band can mow through and 1/8” band might snap on.

All the above can effect the tracking
