  2. Pass the 12" long, 1" threaded rods through p24 then through the tubes (not shown), through p23 and thread them through the nuts welded to the far side of P4. Attach the 4 further nuts to clamp the motor to the tubes, and the tubes against p23, in a sandwich Attach the 4 further nuts to clamp the motor to the tubes, and the tubes against p23, in a sandwich
