Lionel Automatic Crossing Gate Cam

Mounts to the axle of the Lionel 252 Automatic Crossing Gate, so that the solenoid plunger actually pushes the gate down.

The original cam was lost long ago, so I had to base this model off a sketch in a repair manual. Seems to work okay. Please note that I added some sugru to the cam's curved surface, and the solenoid plunger head, to make it a bit quieter during operation. This makes the final cam a bit bigger than what's in this model.
