Design update - Using 4 in. Flat Blank Square Electrical Box Cover (.50 each at HD) and plex for the box. Pics below.
Using Pinsider RacerRik shaker design I decided to build one for my Star Trek. First up was shopping for the motor, eBay was the place. I bought 3 for a discount (13 each with shipping). Next up was the motor holder, I used 3 Hillman 3-in x 1/4-in Metal Slotted Square Plate from Lowes ($3 each = $9). The design was pretty simple using my vice I bent over each side to form a base that I could bolt the sides to. After that I drilled a couple of holes for the motor to rest in. Finally, I used 2 bolts to tighten the top of the motor mount to ensure the motor didn’t move.
For the wire harness I purchased 2 and 3 pin connectors from Vetco ($10 with shipping).
For the counter weights I purchased a 12 inch Steel bar from Amazon. Enough for 3 shakers ($5 with shipping) Using a Sawzall I cut 2 inch pieces. ¼ inch drill blade and my drill press for the shaft holes and the off center taps.
The control board, I cheated and purchased it from Pinball Life. ($30)
Finally, my favorite part the safety case a 4x6 index card holder. $.50
Total cost per shaker = $70
Next up I hoping install a shaker in my Congo. Anyone know if the flasher might be able to power the shaker using the Pinball Life board?
