If the motor can be rewired for 220, that info will be on the motor
somewhere. If you can't find it, don't do it. :-)
But I'm on board with Tom. Sure seems like that saw should be able to
rip right through a couple inches of maple. It's the blade or the
breaker. (Without watching the cut, I also wonder if maybe you got no
splitter on that thing and the wood is pinching the blade. But that
should also squeal and make burn marks.)
I had to replace a breaker after it blew out once, then just kept
breaking every time I turned on the saw. The new one don't blow when
the saw turns on.
Then again, never let it be said I stopped somebody from gittin a new
toy. I'd want the bandsaw before I got a new TS, but maybe you really
want a new TS. Therefore, gopher it.
