Years ago, I bought a small bandsaw from Warco. The idea was that it could be stored undewr the bench. It would break a blade almost before it had cut through a piece of 1 1/2" angle iron. Cost me a fortune in blades, no matter how it was adjusted.
The replacement arrived, with paint in a crack in the casting!
I suspect that the problem was that the pulley centres being so close, the blade was twisted too much for it to be durable.
It was replaced by the 4 1/2" version, which once set up has worked very well.
With the blade tension set with a Jacques Maurel tension gauge it cuts well, accurately, and the blades wear out rather than breaking.
