The blade on my Wadkin BZB20 band saw runs with no for and aft movement, and stays in one place on both wheels. However, it is closer to the back of the top wheel and closer to the front of the bottom wheel. The bottom wheel is fixed to the motor shaft (no belts). I’m wondering if I should move the motor/bottom wheel assembly to correct this, or if I should be happy that there is no for and aft movement and just leave well enough alone. Your advice is welcome.
