Before you throw out those old, broken, or dull bandsaw blades, go "Green". Take that old blade and make strips about a foot or so long. When you have a nice handful, tape the ends together and make a rasp. Alternate the teeth as you assemble the strip. You can make them as wide as you want, or just a few strips. If the blade is a course one, you have a rasp. If the blades are fine toothed, you now have a "rifler" file. A few strips, taped together, can get into those tight spots. One could even build a wood handle by cutting a groove for the strip to fit into. IF you have a way of brazing, or welding, you can use that instead of tape. Anyway, beats throwing the old blades out, doesn't it?
