Picture: https://ift.tt/2A4SaAi; why does my saw burn the wood?I have a craftsman 12 inch sliding compound miter saw. It's using the original 12" blade. I haven't used it very much. Maybe a few dozen deck boards and some 2x4. Whenever I do a long cut like in the picture, I get a cloud of smoke and burn marks on the wood, usually more at the beginning and less later.(Sorry for being a noob) I also get burns if I set an angle either horizontally or vertically. I rarely get a burn on straight cuts.Is it just a dull blade? Can I sharpen it or is it not worth sharpening? Can you recommend a new 12" blade? I'll pay for quality if it's worth it, ie lasts longerMaybe I'm doing something wrong. It only burns on miter cuts, not straight cuts. I suspect the wood moved, but I've clamped it down in several places and have the same result. It also burns both sides. I go really slow at first to minimize the burn, but that doesn't help. On this cut I pulled the blade to full extension, plunged to limit and pushed backwards. The burning stopped after the blade made it to the bottom of the plywood.I propped open the guard to show the blade better. I don't cut with the guard open...Thanks! via /r/DIY https://ift.tt/2zX2cnn
