I was ripping some 1 1/4" thick hardwood (from a pallet--oak and elm, I
think) on the bandsaw and noticed the blade doing something odd. Instead
of cutting straight like it usually does, the blade still maintained a
straight-ish line but seemed to fishtail through that section. The blade
would wobble back and forth through that section. Increasing the feed rate
seemed to help a little, but it would go away on its own.
The guides were a little high, about 1 1/2" above the wood (I had cut
taller pieces just before that and didn't want to adjust the guide, make
sure the blocks were set etc) but I wouldn't think that would be tall
enough to make a difference.
I'm using a 1/2" woodslicer blade.
Why would the blade start to fishtail in some piece of wood? Is it a sign
of too little tension, the blade dulling, or just something inherent in the
