Leon Borre Converting Quarter Mechs to Euro

Adaption of coin mechanisms to euro

Michael Bertling of Berlin Germany was so kind to send a translation of this article ...!

Small models as in pinballs.

I started off with coin mechanisms suited for Belgian 5Bfr. coins. The following pictures show two of these mechanisms as used in my pinballs. These mechanisms are quite average and used all over Europe, though always adapted to the local coin specs. Hopefully the pictures can guide you in finding a solution to adapt them to your own needs.

The first model is an American 'Coin Mech', it is the least complicated mechanism. Adjusting goes as follows: pull the balancing part open until 1 EUR coin fits in loosely and 0.20 EUR falls right through. ...

The balance...............................................the 20 eurocent falls right through.

On the upper side of the mechanism where the coin gets in, there is an adjustable slider to tune the opening. You should adjust it so that the 1 EUR coin still easily gets through, but the older 5 Belgian francs (a tad larger) and the 50 EURocent not. ..

Here you see the adjustment bolt of the slider.

On the second example, there is unfortunately no adjustment on the slider possible. ...

You can however drill a tiny hole near the entry and put in a small screw so that again 1 EUR gets through but 5 Bfr. not.

. Here you see the hole and the screw. ... The balance part also needs to be adjusted the same way as explained above. On the backside of both mechanisms there is a small adjustable lathe for guiding the coin to its further destination.

I found that the correct setting of this lathe is about half way. Just try out a few positions, you'll soon find the right one.

Good Luck!
