Axle suggestions?

Based on your findings I wonder if a 23 or 30 rpm 6v would work... I've started ordering more 6v motors.
12v running on 7.2v cuts speed and torque almost in half... but a 6v running 7.2 give you almost 20% more of both... and a 6v motor should easily handle 7.2v
I wana see how well these fit on your wooldridge bottom dump and see if they hold up cause if they work I want to use them on my tournarocker and tournadozer
