I cut a lot of flitches from small logs as well as do a fair amount of cutting smaller turning blanks from longer/larger boards. After going through countless Timberwolf 3tpi blades (mostly 3/4") I finally upgraded to a carbide tipped Laguna Resaw King band saw blade. $149 plus shipping.
Last night I mounted it in my 14" Powermatic saw, got it tuned up, tensioned and running slick and smooth. I jointed a smooth face on a small 8" diameter log, and with the smooth face on the table I went to resaw the log in half. 10 seconds after starting the cut BOOM! Huge violent catch, like nothing I've ever experienced. I stopped the saw and looked everything over and couldn't find anything out of place with the saw or the log (not pinching, etc.). So I grabbed a 4" board of mahogany and cut a perfect 1/16" veneer off the face of it. Next I grabbed a 4" board of cocobolo and attempted to do the same thing. BOOM. Another huge catch. Tried it again and got it on video doing it a 2nd time.
Guys I'm stumped. The roller guides are set just behind the teeth. I don't see any irregular teeth. Not touting myself as an expert by any means, but I have set up many dozens of blades on bandsaws and have not experienced anything like this before.
Here's the video of the catch on the cocobolo. Turn your sound up. I normally run a table insert but removed it for the purposes of trying to get this figured out.

I'd appreciate any help any of you can offer! Barring any revelations, I'll be on the phone with Laguna on Monday.
