I bought this Rigid band saw new. I wanted to do some resawing and bought the appropriate blade. When I tried to do this cuting black walnut the blade would almost stop.I checked with the maker of the blade and he says I need at least a 1h.p. motor to do this.I also tried to cut some mohagany and had the same problem. I had to cut it dowm into 2" strips so I could resaw it.Is this normal? Why does Rigid sell the spacer block to raise the upper wheel to cut bigger pieces if I can't cut what I have now.Do I need to buy a better band saw?
