Been 6 months since I bought a machine and although I have lots of projects, I bid blind on the matt black Monimat at NL auctions this week, always willing to take a chance for less than a ton and had fancied one since missing out on the one starting this thread


.......anyway I had only noticed that it was the same machine as posted above last year and forgot to check before bidding. Obviously the poster gave up trying to get working, it is funny how many new members on this site and many FB groups make one post asking questions and do not even acknowledge with a thank you or follow up or login again

Anyway picked up from this small auction house who had only 30% sales from the auction, very sad and an old school establishment. On getting home I was glad to see a mostly complete mechanism inside and cash box, but not working. Very quickly I could establish clock was not working and sure enough mainspring had exploded..


As BP had stated they are very similar to the Gunter Wulff versions, but sit differently and seem more robust (apart from spring) with race bearings on top of each pivot. So I nicked a clock from a Beromat and made a frame for the alternate mounting position and wonderful the machine works and pays out.


I have a timing issue to allow the reel stops to lock properly as the actuator trips before they engage. Pay disc needed adjustment as well. What a cute little machine and as BP stated nothing like the other German machines, very well constructed, even the case. I might change the Vauxhall Viva gear stick used as a handle, apart from anything else it does not actually fit Got a nice aluminium Gunter Wulff handle I will adapt.




Also whether to risk stripping the tarmac paintwork off the machine as no idea what it is hiding apart from the missing badge. It is just like that road surface you get just before a pedestrian crossing, a previous owner must have worked for the highway agency...anyway it started to come off the brass window frame, so may take a chance, also some kind of award plate.


One thing I forgot to mention, I had also just remembered I already have one of these machines in the square case, bought at auction 5 years ago and have never looked inside as was locked Might inspire me to take a look inside and may help with issues on other one

Well done Tom.

I was looking at it, but too far away, and I already have enough projects weighing heavily on my elbows.
As you'll know, but others may not, one of the most important parts is the cash box. Without one it can't pay out, as there is a tunnel that goes thorough it linking the bottom of the slides to the cup .... Weird!

I love the Viva gear change for a handle, does that mean you have to be in reverse to get a jack pot?
If you want any photos of the inside or the badge, just shout and I'll get it done.

Well I got out my other Monimat for comparison and managed to get inside taking the back off, fortunately a cash box existed in this one. Anyway I managed to work out how to adjust timing, there is a slide adjuster for the play actuator held by two hex nuts. Slid this down to allow a longer operating stroke and voila, works perfectly now.


So in the mood and started stripping the black goo from the cabinet and to my surprise came off easily and the main cabinet is in good condition.


So onto the front panel, which appeared to have a heavier layer of black stuff, think it might be that old car undersell stuff, anyway scrapped away top layer to find a layer of white crap, looks like plaster or maybe filler, who knows, but the paint stripper does not loosen it. Bugger knew I should have left alone....now to see what might loosen it up a bit as what wood I can see underneath looks good......I wonder if the person who did it was a car mechanic or painter and decorator

Are there any mechanisms you can not fix tom? Well done Succes with the wood work

Well done for saving another machine. Why would anyone paint it in black goo? Looking forward to seeing it finished.

Ha ha, I really need to read previous posts in more detail. I was always told off as a kid for starting a book at the back as I could not be bothered with the bit in the middle and beginning.....BP had already pointed out the same issue with timing and the adjustment plate on his machine, genuinely missed

...... had I? I forget.

Had enough today, still some cabinet work to do, but love the two types of wood used, sets off nicely. Out there somewhere there is a Vauxhall viva with a Monimat gear stick and badge on the back.

Might get new glass done with awards and trying to decided what to do about missing badge. That black and white crap was the hardest stuff I have had to remove from a machine, especially as you are trying to avoid damaging the wood. Reckon it had been on there a long time

Wow - what a transformation - and in record time!

That looks superb.
What a strange choice of chemicals to smother such beautiful wood in.
