A friend showed me how to mod a metal coin mech to accept any coins. Works great and doesn't jam or fail.

Here's a Quarter mech I want to mod to accept .900 tokens.

Remove the cradle and arm. Just use pliers to remove the clips.

Don't need these parts anymore.

Now remove the bottom pieces by taking out the screw on the bottom left.

Bend the back piece on the top left so it closes the gap and the coin can't reject.

Now the hardest part of the mod is getting the screw back in. It takes some back and forth of adjusting the bends. A longer screw would probably make things easier. Of course the more you do this the easier it gets.

That's it! Coins now just fall straight down and you can coin up your machine with Quarters, tokens, pennies, slugs, ect...

I use a hot glue gun to create a ramp over the reject slot, guiding the coin to the accept slot. Usually I can create an adequate ramp without disassembly, though the plastic ones just snap together so disassembly is pretty trivial anyway.

I also leave the cradle in but bend it as needed for tokens. I'm really only targeting .984's though. I can see that if you want it to take anything, removing the cradle would be the way to go. I'm guessing it loses a bit of the normal coin insert series of sounds but if you want to accept any coins and/or you don't care about the authenticity of the sounds, your method is a little easier.

Bending the metal is another creative technique though! It's good to have multiple techniques since everyone will have different preferences. Nice writeup.

Good tip on hot glue. That would be the way to go with plastic mechs. The sound differences by taking out the cradle is barley noticeable.
