Last week I made some drive rods for the locomotive project and installed them. I cut them on the laser from two layers of 0.025 inch laser board. Then I glued the layers together. They fit very nicely on the crank pins that come with the Slaters Wheels. This short video shows the trucks rolling on the track.
