Hi, got a new band saw blade. when I installed it it won’t stay on the wheel, guess I messed with the wheel adjustment to much. But it is doing something I don’t understand, I get the blade centered on the wheel as close as I can. Then I slowly turn the top wheel and watch the blade, the blade on the right side of the wheel will stay put or come forward a little while the blade on the left side of the wheel runs off the back of the wheel. I have tried adjusting the wheel but the blade wants to run off the back here is a pic. Note in the upper corner of the wheel you can see the blade on the right but on the left there is no blade because it has run off the wheel at that point any ideas what I can do thanks Mike

The relationship between the tracking adjustment
and the blade tension can be fussy. I’d start
at low tension and fiddle with the tracking
knob while rotating by hand. If you can’t
find the sweet spot with the tracking knob,
get close and add some tension, then try
the tracking knob again.

They are independent of one another. The tracking adjusts the tilt of the top wheel, while the tension affects its height and therefore the tension of the blade.

I adjusted the position of the blade on the top tire (tracking) according to the Snodgrass video a couple of years ago and haven’t had to touch it since. I do deal with the tension pretty often though, changing blades and the like.

What you describe makes no sense unless 1) something is interfering with the blade and pushing it forward/backward somewhere, 2) the wheels are way out of spec and one is seriously out of whack, or 3) the blade is defective. Does the same thing happen with your other (old) blade? If not, then I’d suspect the new blade and start by laying it flat on the ground or similar to make sure it’s not warped.

Cheers,
Brad

Brad you are right it don’t make sense, when i try to get the blade in the blade guide to go back som I can move the blade back on the wheel i can’t get them to line up, I loosened the thrust bearing up and moved them back but it don’t make any difference. tomorrow I ‘ll check the blade for warps thanks Mike

I am going to post the Alex Snodgrass video, and he will tell you at exactly the 6 minute mark NOT to adjust the wheels on a bandsaw, because the manufacturer put them where they wanted them to be. Moving or changing them will mess you up.

So look at the video, and when you are satisfied this guy who travels the country, and will walk up to the bandsaw you brought in, and use it after only a minute of fiddling. That bandsaw will be said to cut as well as the best bandsaw on the planet. He’s got the chops. Only question is will you believe him, and call the manufacturer for instructions of setting your wheels, which is what needs to be done.

6 minute mark. The entire video will help you a lot, but not until you get the angle of your wheels fixed.

Good luck.

Not to be insulting, but have you moved BOTH thrust bearings back; upper and lower? You mention one bearing, so I just thought I’d throw it out. If the lower is too far forward it could be pushing the blade off.

I second Brad’s suggestion; try an old blade and make sure the problem isn’t with the new blade. If the welded ends were cut at angles, you’ve got a cone instead of a band, and I can’t imagine that would work well.

Check the wheel mount shaft it may be bent.

No offense intended to those who already
have woodworking completely figured out,
but sometimes my experience has yielded
different views.

I’ve had a few saw with fussy tracking where
I was never able to just crank on the tension
and adjust the tracking after. I never made
a scientific study of the issue but I have
read on a book on band saws before. There
are lots of things that can be a little off on
a band saw and even saws in apparently good
condition, particularly smaller ones, can have
little quirks.

Creeping up on the tension while tweaking the
tilt knob has worked for me in some of these
tracking situations.

I’m getting tired of being anitpicked here by for
having an opinion that differs from some
expert-du-jour with YouTube channel.

I’m sorry to see the forum go this way, but that’s
what I see and I’m probably going to stop
participating much.

You can’t handle someone disagreeing with you, so you insult them? Expert du jour with youtube… Ouch! LOL

My first comment about their independence was based on my knowledge of mechanics that I learned in engineering school at the University of Wisconsin. My second comment about my saw and how it has not required tracking adjustment even with multiple tension changes was based on personal experience with a saw that I’ve owned and used for over fifty years. Finally, the Snodgrass video is the de facto standard on LJ for band saw setup. It was even mentioned in this thread after my post and, in fact, seems to be linked to in most threads about band saw issues.

You’re right that there are many things that can be off on a band saw, and you’ve obviously run into some of them that you were unable to understand.

Well, at least you’re going to be mature about it. I don’t get the part about the forum going this way though. Can’t you handle your ideas being challenged? Don’t you want to have to support your statements? I know I do. I like to be questioned about things I say — it keeps me honest. There have been plenty of times I’ve realized I missed the mark and wound up learning something new. I like that. Rather than making me want to go sulk, it makes me want more because I want to learn all I can. LJ has certainly taught me a great deal, and I look forward to much more in the future.

My first question would be; did you have the problem before you put on the new blade? If not, the new blade would be suspect.

Experience is a lot like a certain body part. Everybody has one. It’s my opinion that you are an easily bruised fruit.

Now I learn some by reading, much by actually doing, but when teaching you can ask a real teacher, and the best medium to present for the best COMPREHENSION, and LEARNING is TV, Video, something with a wide visual acceptance that speech, and or writing cannot convey as completely. A hint to you, it’s why magazines about woodworking are folding at the rate they are, there is a new Sheriff is in town, and his name is VIDEO.

Because I will post a link to a You Tube doesn’t mean if I was standing right there I couldn’t SHOW you how to do it correctly. You will also see where I type detailed instructions. Maybe you haven’t noticed, but I have, that my instructions, and yours are very similar. I really don’t GARA if you are offended by me, think I don’t know anything, whatever makes you happy.

Now, going forward you can do one of many things. It appears some would miss you if you did take your toys and go away, and that’s also not being very BIG now, is it. So why don’t you open your head to the FACT that there are always different ways to do anything.

If I knew how to make a video, I would, but I wonder if you would be an happier. So I go to the video library for woodworking, and find one that conveys to whomever I am attempting to tell, show, reach, what I think they need to know, and present that. Again, you don’t like that (shrugs shoulders) I don’t GARA.

See above the snip of OP’s initial statement, and why like a LUMMOX I don’t think it has skinny to do with the blade. He changed the tilt of the wheels, also why I posted Alex’s video, and specifically directed the OP to the section at minute 6, where a guy who knows a LOT about bandsaws says very emphatically leave the angles alone.

Like Loren would suggest, I don’t know anything, but I once slept in a Motel 6 :-)

Children quit bickering, My take on knowledge is #1 I am stupid therefore must ask questions and #2 no matter how expert you are there is always somebody that know something different. I appreciate everybody’s input it is a great help. I have watched the snodgrass video several times, once before I presented the question here. Yes he says not to adjust the wheels but that is irrelevant the wheels are already messed up. I haven’t tried loosening the tension but that may be it. I saw a clip snodgess did the mentioned deflection and found I was a little loose. therealSteveN I have always had a little tracking problem Thanks Mike
