MY team did this style shifter once. We were running it on an arm, so the torque was a lot higher. We used .375" diameter pins, which were just in a drilled .375" hole with retaining compound. The holes we had them mesh with were on the same size circle pattern, but 1/16" bigger. The shaft it ran on was a .625" keyed shaft. We just ran the power and the sliding through the keyway, it put up fine with it. Meshed very nicely, never had any problems. This was however, a low speed, high torque gearbox. Keep that in mind. Also keep in mind that this was a quick modification made in a day on a drill press and mill. Otherwise, these are a lot easier to make than a real dog-shifter. No cnc. A very ghetto solution when we used it, but it can be made very nicely into a drive train.
