I bought an older craftsman 12” bandsaw the other day for $90 off craigslist. I watched a bunch of videos and read stuff about tuning it up and yesterday that’s what I did. It came with a 1/4” blade. Who knows when it was last used or how it was abused. It didn’t come from a woodworker, but rather a craigslist trader. I kind of bought it on a whim because it was inexpensive and i’d like to do some projects with it this summer after the rest of my project queue is finished. It has a 1/2 HP motor. I’m a novice woodworker in general and I have never used a bandsaw except maybe once in junior high shop class.
Anyway, I think I tuned it up pretty well. I got the blade to track properly and adjusted the guide blocks and thrust bearings to the dollar bill test. I have a couple of issues that I need advice on.
The belt tension is almost non existent. I adjusted the motor mount to try to tension the belt but there is still very little tension. Is it supposed to be like that? When I did a test cut after all my tuning I noticed that there was some slippage when the blade got bogged down.
Speaking of getting bogged down, that’s precisely what happened. Like all the time. I assume at least part of that is due to the old blade. My test cuts were done on a piece of 2×3 so the thickness was 1-1/2”. It bogged down and burned the wood and took what seemed like a long time to cut. After that I tried a cut off edge of a 2×4 that was maybe 1/4 thick. It even bogged down on that but less so and still left burn marks.
Also, while I was pushing the wood through the blade there were sometimes sparks coming from the guide blocks. I assume that’s because the guide blocks were set too far forward. Not a big deal for this blade but I don’t want that to happen with a new blade! Or maybe that’s normal? I don’t know but I doubt it would be.
And lastly, how the heck to I change the blade? The tensioner doesn’t seem to move far enough to simply pull the blade off. Do I have to intentionally misalign the wheels to roll the blade off? I haven’t tried yet. Thanks in advance for any help you can give.
