Projectile Launcher - Photogate Mount

This is a simple mount that allows you to position either a Vernier Go Direct Photogate or the Arbor Scientific BeeSpi Photogate timer at the correct position to catch the launch speed of the projectile launcher.

It does require a square nut and a 1/4-20 thumb screw to attach to the bottom of the projectile launcher.
