I use this contraption for bushings, among other things. I use KWM bushings and tools. The reamers fit the adapter somewhat loosely and self-center, so drill press run out is not an issue if you’re careful. The holder for the clock plates is commercially available. I’ve attached a steering wheel spinner to the forward pulley using a section of v belting and a modified clamp, so I can do delicate work slowly, by hand, for more control. The spinner can easily be removed to run the drill press with the motor.
