A lot of folks have bad shop habits. They may get away with something 1000 times, but it's that 1001st time that gets them. I see it all of the time (and I am guilty of a few of my own, as well).

Last year, a guy put his hand into a jointer pushing a board through in a very well known woodworker's class. People may get offended by correcting this kind of stuff, but the reality is that a pushblock is sacrificial. Everything behind the pushblock is not.

Unlike a jointer, a bandsaw has two basic rules: The workpiece needs support and you don't touch the sharp spinning thing. If you forget #1, you will kink a blade in that split second, and it becomes a very expensive lesson.

Rule #2 is really really easy. NEVER, EVER, have your hand moving towards the front of the blade. It's the only way it can cut you, so find a way to never get cut. I use a sled on my tablesaw so my hands are not near the blade.

All bandsaw injuries are user error. It is probably one of the most misused tools in the shop, but completely avoidable. Unlike the lathe, where natural issues can occur like a ring shake, I've listened to lots of excuses about what went wrong and it always boils down to moving one's hand into the thing that cuts wood.

Do beginner bandsaw classes exist? Not that I've seen...
