The bandsaw is useless – and dangerous – if the blade keeps slipping off. If your blade slips off after you exert additional pressure, yet the blade isn’t dull, then your blade may be falling off of the rubber tires. The last possible reason why your bandsaw blade keeps coming off is from wheel wobble.
You have to get the blade tracking in the middle of the tires with the blade guides backed off and not touching the blade, just keep turning the top wheel by hand and adjust the tilt until it tracks in the middle of the tire, then turn it on and make sure it stays there, then after your satisfied with the tracking of the blade set up your guides. If your blade is damaged there is a good chance you won’t get it to track properly, you would be better off to throw your old blade away and start with a new blade right from the start of the set up. P.S. you never said anything about the blade if it is the original ,I would suggest getting a new 1/2″ 3TPI blade and trying that first, thats the size of blade I run on my 14″ Delta for 95% of my bandsawing.
This last winter I just gave up, and bought a cold cut saw from Northern tool. It does every thing I need, costs less, and takes up less room. I think that a lot of the problem was in me expecting the saw to make heavy duty cuts that it probable wasn’t intended to do.
I think the blade may come off if the blade stalls and the pulleys keep spinning. If the blade comes off when you try to cut, but stays on when not cutting, it sounds like the blade guides are not adjusted properly. If the blade grabs at all, the drive wheel slips, and oops, the blade comes off.

Why does my bandsaw blade keeps coming off?
Blade Tension Is Too Loose The most common reason why the blade is slipping off is that there isn’t enough tension to keep it on. Blades can slowly become loose after years of wear and tear, and eventually, you’ll need to tighten or replace them.
How tight should a metal bandsaw blade be?
The blade should deflect no more than 1/4 in. A good place to begin is to tension the blade until the meter reads proper tension for the next wider blade. For example, if you’re tensioning a 3/8-in.
What causes a bandsaw blade to drift?
Drift is cause because the blade buckles under the load. You can see that by stretching a ribbon between 2 points and applying a pressure to one of the edges, it will turn sideway easily. A sharp blade and high blade speed will help a lot with that.
How much tension should a bandsaw blade be?
For carbon steel toothed blades (cutting blades) this is typically 15,000 to 25,000 PSI. Slitting type blades typically are tensioned in the range of 12,000 to 20,000 PSI. In general bandsaw blades are never tensioned past 35,000 psi.
How long should a bandsaw blade last?
On average your bandsaw blade should last 6 months to as long as a few years depending on what your cutting with it. Make sure to match your blade strength and quality to the project and material your cutting.
Why does my bandsaw blade wobble?
The blade on a saw left idle for long periods of time can leave an impression in the rubber tire which might cause erratic tracking. Purchase and install aftermarket replacement tires. (Search for “bandsaw tire” at woodcraft.com.) If you still see a back-and-forth motion, the culprit is probably the wheel itself.
Are bandsaw blades worth sharpening?
Since a carbide-tipped bandsaw blade will cost well over $100, spending a third of the cost of the blade (or more) to get it sharp and working like new again can make financial sense. However the majority of bandsaw blades, the Wood Slicer included, are not worth spending money to have sharpened.
How many times can a bandsaw blade be sharpened?
It often makes sense to replace a dull blade with a new one, but you can sometimes get the best value out of merely sharpening an old blade instead of replacing it altogether. You should typically be able to get two to three sharpenings before you need to change your blade completely.
How many times can you sharpen a sawmill blade?
You should be able to sharpen your blade two or three times before needing to replace it, but sometimes breakage happens. Blade breakage can result from a range of situations. Common causes of blade breakage include: Dull teeth.
