I have a rockwell/Delta wood lathe and I need help. I want to put a wooden wheel on the spindle end at the motor end. The spindle working end has a 1" x 8" spindle end. On the opposite end, where I want to add a wheel, nothing with a 1" x 8" will screw on the spindle. Does it have left hand threads? Any help would be appreciated. Thanks, zetuskid
