Installing the Shaker Motor

 

First, pick a spot. On my ST:TNG, I decided to go with the space between the cashbox divider and the transformer support. Next, drop the template in place. It needs to be clear all around of wood, wiring and other obstructions. Drill a pilot hole in one of the corners, then drill the pilot hole out to take a #10 T-nut.
Push a T nut into the hole from underneath. Hammer it in: drawing it in with a screw will bend the prongs and cut little wood circles.   Put a #10 screw in through the top. Tighten it down to draw the T nut into the wood. Make sure that the template is where you want it, and drill the other three holes. Push the other T nuts in: tap them gently so that they don't fall out as soon as you touch them. Then, hammer them home. Remove the locating screw and the template.
Drop the shaker assembly in place. Fix it down with four #10 screws. Tighten them to draw the T nuts into the wood. The final installation will have finger guards.
