The blade popped off my bandsaw today while I was using it. At first I thought I had broken the blade, but when I opened up the saw it was simply come off the wheels. I am pretty sure the problem was that I had too much tension on the blade. I find it hard to determine which way is looser and which is tighter on the adjustment screw on this Rockwell/Beaver saw, manufactured in 1981. Before the blade popped off, I had tried to reduce the tension on the blade, and probably turned it the wrong way. Anyhow, it is now, after a few minutes fussing with it, at a good tension and running fine.
The wheels on this saw are not coplanar, and I know that the know wazos say that doesn't matter, but the blade runs at the front of the lower wheel to such an extent that when using wider blades the teeth are over the edge of the blade. I would like to know how to adjust this, just for my peace of mind. On the upper wheel the blade runs at the centre of the crown, and it cuts perfectly straight.
Also, the lower blade guide sometimes does not engage the blade. I took a photo, but it was hard to focus and I didn't get a good shot, and I'm not going to take the damn thing apart again just to photograph it. So, at present the guides engage the back half of the blade, but I cannot move the guide any farther forward, and the blade is sitting about 3/16" from the circular guide thingy. Sometimes it has not engaged the blade at all. I have considered taking a round file and elongating the bolt hole for the guide in order to move it farther forward. Does this sound like a bad idea, or am I missing some fundamental point about installing a blade in a Rockwell/Beaver (now Delta) 10" bandsaw?
