How to make a C.R.A.S.H. Space Store Front Music thwacker

Step 4: Assemble the shuttle

The shuttle is the part that I call that slides back and forth. It can be called a number of other things such as slider, the mover thingy, or the even the slider mover thingy. 

These technical terms are all OK to use.

The shuttle is assembled in the same way as the mount, note the order of the stack, but most importantly, the steel dowel pin and end of the solenoid will be encapsulated in between the first and third layers.

DO NOT OVER TIGHTEN THE SCREWS.  YOU WILL STRIP THE PLASTIC THREADS.

1) Tap all four (4) holes using the same method that worked for you on the thwacker mount. 
2) insert the pin in the solenoid pivot hole
3) align the three layers of the laminate together and ensure the pin is trapped inside.
4) Screw the parts together using four (4) of the 3/8" long screws
5) make sure the plates align and are tight

(this part is tricky, you will probably use some colorful language as you try to trap the pin in between the layers as you tighten the screws
