Very quick increase in required feed force
I know what you think: the blade is dull! However, this happened rather quickly. I was cross cutting wood with no problem. The moment I switched to ripping, the feed became more and more difficult with every rip. I had to apply more pressure, but the blade (Dewalt 20 tooth universal blade) was not burning wood, and the quality of cut was fine. After the fifth cut I decided the blade is just dull and it is not safe. I switched to another blade: Haussmann 200 tooth plywood blade. I know, it is not even close to ideal for ripping, but that was the only sharp blade I had left. This time it started burning wood right away, making a lot of smoke and I stopped half way through. Here is the picture. Any ideas what is wrong?
