arcadus Posted June 6, 2017 Share Posted June 6, 2017 Another one I picked up a few years ago. Rare but probably not valuable, made by London Coin Machines Pty Ltd. No info on machine or manufacture on the Internet. Big machine standing at 2 metres. All 240VAC motors and relays. The control relays and sound unit are in the head behind the marquee requiring a ladder or milk crate to service... I started this a couple of years ago until I found all the motors were badly worn and had to be replaced. They operate continously when the machine is on- attract mode. Unable to buy any with the all the right specifications, I bought 10 microwave motors in a package. The original shafts are 4mm, the new ones are 7mm requiring the cam plate to be bored. There is still just enough thickness. Link to comment Share on other sites More sharing options...
arcadus Posted June 8, 2017 Author Share Posted June 8, 2017 The cam plates have been drilled. The hole in the shaft lines up with the one through the sleeve. The relay unit. Bear in mind this is all 240V. Perhaps the unit is up in the head for safety reasons. Link to comment Share on other sites More sharing options...
arcadus Posted June 20, 2017 Author Share Posted June 20, 2017 (edited) For random target operation, the targets are wired in series to this spinner. When all the targets are in home position, this spinner spins pulsing the targets until one eventually moves off home position. The target opens the circuit to the other targets and spinner until it homes. The original motors were onedirectional, the new motors are randomly bidirectional. If the motor starts backwards, the cam plate travels backwards until it hits the backof the microswitch blade then reverses. This means the target appears twice. Doesn't really affect gameplay other than occasionally the target appears twice in a row. The sound unit has had a few mods, caps added, component leads cut. It was faulty with blown o/p stage and speaker. Replaced the O/P transistor and driver, now ok. The white noise generator failed while testing. Transistor ME4102 was faulty. Not easy to find , I will try a 2SC3329, when it arrives. It has a really loud 50Hz hum isolated to its own P/S. P/S is basic halfwave rectified. Tried adding caps (not the caps in pic1, they are trigger timers) but not making much difference. Replacing diode made some difference. I was thinking of fitting a regulated supply but that takes away fron originality. Perhaps the hum adds some 'ambience'. The cabinet is made from strips of light pine sandwiched between thin ply. It is lighter than plywood. The damaged ply peels off easily making this reasonably easy to repair. Edited June 20, 2017 by arcadus ummm Link to comment Share on other sites More sharing options...
arcadus Posted June 28, 2017 Author Share Posted June 28, 2017 Reclad the easy bit, the back and top. Spent some time tracing the artwork. The green blob is a tank..still haven't worked that out properly. Might take a break from this for a little while. It's freezing in the shed . I could warm up over a couple of W.G. monitors sitting in the workshop. Link to comment Share on other sites More sharing options...
