I've been using a 1/4", 6 TPI blade on my bandsaw trying to cut what would seem like not too tight a radius circles (4" - 5") and the blade is burning the wood pretty badly. It seems to do it on any hardwood (haven't tried it on pine). I don't feel like I need to go to a smaller blade because I could have sworn I've seen this done with a 1/4" before. I'm not using a very high quality blade. Is that the cause? I've read that rounding the back of the blade is helpful. Is the burning just a normal effect of cutting tight circles? Thanks.
