Anyone have any knowledge?

I've been doing some virtual carding for a few months, and it's going ok, but I've decided to go into real carding. I have AN MSR reader/writer and cards to use, I was just wondering if anyone could give me some technical info on ATM's. Where I'm located in the US, most machines are 5-10+ years old, and mostly diebold or hyosung. I was looking into forks, and I understand the concept of them, I just don't understand how they work in practice. If all you're doing is wedging the cash door open, then why not just use a solid piece of metal? And why are they hinged? Probably noob questions, but I don't know the particulars of internals of these machines. I was also wondering if anyone had any sort of schematic for a insert card skimmer or the type that plugs into the inside of a gas pump. I can easily fabricate metal and electronic parts, so I should easily be able to manufacture myself. Of course I'd be willing to pay (with escrow) for any schematics anyone has of these devices, and if anyone has any for sale at reasonable prices I'd also be interested. Thanks in advance guys.
