My Spook reverses direction by way of a toggle switch. I ran this in series with the coil of my reversing relay. I used "S4" plug with was the limit switch. I only have side to side motion, so I do not need to stop motion at the front.
Coils for them are non-existent. I rewound one of mine that was melted. A complete machine will just take time to clean and fine tune it. How much do you like this guy?
I bought one for $100 and was happy to sell if for $300. I do not know your market. If you are trying to make money, run away. As a passion/friend project, get it cheap and enjoy the ride.
The Gremlin is more complex than an earlier Midway version. The Styrofoam focuses the light beam and did not originally stick to the lid. My history is on the Midway version buy I can help where I can.
I'm not an artist. I purchased that off of eBay. Also, I want the outer cabinet to look stock. The port hole is quite small and this poster will fill up the back drop.
