So I’ve got a wierd situation. Sometimes I get burning on my table saw, and sometimes I don’t. My setup is a G1023RL with an Infinity Super General blade.
Cross cuts seem ok, not the greatest, but ok. I think any burning from the cross cuts have been cleared up by a good blade cleaning I did.
For rips, it is a mixed bag. To cure the burning, I followed the usual steps:
The plywood would burn occasionally, and sometimes it became harder to feed the stock into the blade. So that left me thinking my fence wasn’t accurate and was pinching. But I can’t seem to find any evidence that is the problem. On long rips, I have to pause and regrip the wood, which is sometimes the culprit (but I still notice burns on short rips with even feed rate).
The poplar and maple I ripped the other day was burning so much it was starting to smoke. But some areas aren’t burned at all. It is almost like it happens at random times during the rip.
I should say that I’ve tried to take myself out of the equation as much as possible. I have the yellow magnetic featherboard that I use to ensure constant equal pressure against the fence.
Is it possible that the blade is the culprit? I’ve only ever used the Infinity Super General. It leaves an amazing smooth surface on the cuts, but could the high ATB be causing some burning? Could the blade actually be dull and I don’t realize it? When do you know it is dull? It still is leaving a mirror smooth finish on the cuts (aside from the burns).
Should I put the stock 40tooth blade from Grizzly that came with the saw and try some rips to see if the flat tooth style is any better?
