Unfortunately, the best source of information regarding these machines was lost when the expert Harold English passed away, RIP Harold. I often wonder what I will do when both my machines I got from him decide to pack up. Good luck with the Rotamint, I really like them and find them fascinating to play and often wonder how their mechanics work. They are certainly a niche area of penny machines collecting, not to everybody's liking but personally I love em.

Hi! I need a new frame motor for my Duett.
A couple of photos for you.

Rotamints

Topic moved & merged - Site Admin.

I picked up the Rotamint at the Coventry auction. It was pretty cheap so I wasn't expecting much from it. To my surprise it worked (sort of) and obviously has had some restoration work done inside. Messing about with these things is new to me so if anyone here can help I would appreciate it. All the wheels spin, although judging by a Youtube video of another machine, they may not be running at full speed. They stop in sequence and the payout works. The stop pushbuttons however don't appear to work so it's not possible to manually stop the wheels. All the pushbutton microswitches have been replaced with new ones. The note below was inside the machine so may be a clue.

I can see the yellow/red wire it refers to but can't identify its connection point. Perhaps the previous owner gave up trying to get it work 100%. If the seller reads this I would appreciate some feedback. You can PM me if you prefer. I would like to restore it cosmetically but it may not be worth it if it isn't going to work properly. Having done a bit of internet digging I think it may have been sold previously on eBay as it looks identical to the one in a listing from June this year (seller in Mablethorpe).

My experience of them is that if they run slow, but the motor seems up to speed then it's the spring bands/belts slipping.
Either oil has dripped onto them or they've stretched.

Also the skill stops aren't immediate and I seem to remember they each operate within different time periods of the cycle .... or am I thinking of the later model that has a lion on the front that winks?

Thanks, here's a pic of the top block of switches and the disconnected wire poking up from the back. If you can see where it's supposed to go I would be a happy chappy. I have to wonder though why it was disconnected in the first place. Better get the fire extinguisher ready! Bottom pic shows the new stop button microswitches which I have to assume at the moment are connected correctly.

Jonesthegarage, are you still able to help me locate the correct fixing for this yellow/red wire. Here's a pic from the other side of the bank of switches. The loose wire is the one with the tape on it. Many thanks.

Hi Hiflyer, sorry for the delay but it looks like they will be no use to you anyway. Mike

First check it doesn't go to earth.
Is it live?
Use a continuity tester and trace that wire backwards until you identify what it serves.

If there is a problem with the skill stop on a reel, and you have a loose wire, could it be related?

Edited, because I've just remembered back in the 80s I had one of these that was showing an intermittent skill stop issue. It turned out to be one of those weird combinations of circumstances at first that defies explanation.
It originally worked fine whilst some of the bulbs in the buttons were out.
After the bulbs were renewed it started going odd. I think power was shorting from the bulb connector possibly to the micro switch which allowed power to continue to the reel stop solenoid allowing it to stay out, consequently the reel doesn't stop.

Seems it could be a common issue, incidentally if I'm right it could make the metal chassis live, probably to the tune 115 volts.
So make sure you stand in a bucket of water ........ I might be wrong there, as I can't be trusted.

Good luck BP

OK, thanks guys. I'll just have to keep investigating. It would be so much easier if I could find a wiring diagram. I have traced the yellow/red wire to the back of the coil which controls the centre wheel. It is connected to the top terminal of the contact switch. You can see it in the pic below showing the bank of three coils removed and turned around for viewing. Just need to know where the other end is supposed to be connected.

I have cured the slow wheel problem by the way. The bank of metal pulleys on the back of the motor shaft were slipping too much on the shaft so I took them off and cleaned all the excess oil of the shaft and bearings. Problem solved.
