Last night for part of the program on jigs and tips at TWA, I took in my band saw blade. It's a 1/4", 0.025, 6 TPI, hook pattern, bi-metal blade. It has been on my saw since 1999. I've cut hundreds of little cars for Toys for Tots program, in addition to everyday use. Car bodies are cut from 2 X 4 stock. The cars are "Volkswagon style, and in that vain, I use lumber imported from Germany. I buy the lumber from Lowes. Before I took it in, I cleaned the blade just as you would a TS blade. Tonight, I reinstalled it and started cutting car bodies ( about 100.) The blade cut a lot better than last time I used it. A good cleaning was as good as a sharpening, IMHO.
