I've noticed that the instruction sheets for my bandsaw blades recommend loosening the tension after I finish using the saw. However, I often forget to do it, and I don't see any noticeable issues. What's the reason behind this practice? Do you guys loosen your bandsaw blades? What could happen if I don't?

I've heard that keeping tension can actually cause the steel to stretch over time, which might lead to issues like an oval shape and increased vibration. But honestly, it doesn’t worry me much; if I forget to release the tension, it's not the end of the world. I do it when I think about it, but I wouldn't sweat it too much if I forget!
I never loosen my bandsaw blades either, and honestly, I haven't run into problems. I feel like it's one of those myths floating around online. I mean, look at guitar and piano strings—they’re constantly under tension, and nothing bad happens to them. Seems like bandsaw blades might be in the same boat!
From what I've gathered, keeping the blades under tension for extended periods can put stress on both the blade and the wheels. This could lead to fatigue and possibly even affect the weld on the blade, which is its weak point. It's usually a good idea to re-tension before each use to maintain accuracy, especially since these parts expand and contract with environmental changes. But if you're using the bandsaw regularly, it might not be as critical.
Exactly! I think it's really more about the longevity of the blade. If you’re using it regularly, it’s probably fine just to leave it as is. Just keep an eye on it!
