Life Test of Pawl and Ratchet

To find better materials for the ratchet and pawl, I made this test fixture from a 25 rpm gearmotor. Initially the ratchet is 642 bronze and the pawl is 6061T6 aluminum. I expect the aluminum to wear quickly. May try bronze pawl next.

    fascinating test engine. wanted to make an observation regarding bronze
    ratchet: i field tested a bronze ratchet vs a mild steel pawl and found wear on it
    that was visible to the naked eye after just a few minutes of twisting both in- and outbound.

    have switched to a stainless steel ratchet and so far have found no wear.
