I've got a couple bandsaws, the one in question being a 14" Delta. It is exactly as it was when it left the factory, except it's on it's 10th or so blade, and has new cool blocks. I use it for the odd job saw, so it gets used often. I was using it tonight, and I got to thinking, the last time I remembered to release the tension was probably when the last blade went on. That was a while back, maybe a year? Come to think of it, I haven't religiously released the tension since I bought it used, many years ago. There is no vibration, and the saw works just as it did when we first met.
Am I missing something, or is the conventional wisdom on releasing the tension a little overblown? Opinions?
