the first lever that pound coin passes through 9 times out of 10 has to be rounded off on the end or you will find it wont accept the old pound coin as lever catches on edge of coin plate as new one is bigger it lifts lever no prob but old one is smaller and dont lift it as high after grinding. on some ive even filed edge of rhs of coin carrioer to allow it to pass with old pound coin.
also retention spring needs to not have to much tension on it or again old pound coin wont go through.
coin plate change is only half of the job

What Ade says is spot on.
In Truth, No two mechs are EXACTLY THE SAME!
Many of us operators have Chinese machines which all have mechs that were reverse engineered, most all of dubious quality, some have tighter tolerances than others.
This is not a one plate fits all project!
If you can modify your own as you go round like Ade is doing, all credit to you.
The next best option is to post them to the Engineer I have used whom will stand by his work with no Quibbles.
See the technical forums for full details!
