A small feat!

I got an 81B mech from a customer who owns a retro gaming shop in Houston.
He wanted his coin mech to work on tokens that he would sell for a dollar.
I switched out the nickel/dime rejector for a quarter rejector...made a few modifications and it works like a champ. Pennines, nickels and dimes fall straight through to the coin return cup, quarters get stuck and are scavenged out by the crank and tokens go straight into the mech.
Something to think about if you want to use your machine to make money!  

Same modification would work on any SD mech - ie. V-39, V-81 A or B, C-51 as long as a quarter fit into the coin bezel - they do on a cast bezel, but not sure about the stamped bezel.

Excellent idea!  I had thought about something like that for a friend of mine who has a chocolate and sweet shop and would like to put an old Coke machine in.  I will have to tell her that it could be done.  Where the tokens like the ones used in pinball arcades?

For the young guys, a pinball arcade is where us older guys used to go to spend all of our money!

They measured just under the quarter size and that is best because I have to fab an new larger oversize post to replace the quarter oversize post - one that will block the quarter, but still allow the token to get by. A couple of other minor adjustments too.
It can be restored to look new and nothing on the mech itself is altered, so to go back to original just requires installing the nickel/dime rejector again.
