TDK Dollar Casting Questions

[Indywan]

Hi. I want to make myself a replica of the Two Face dollar from the Dark Knight, But I was wondering How I can mold/cast it to preserve all of the "ridges" along the edge.

The replica that PTK made solved this dilemma by molding the "clean" side of the coin with the entire rim of the coin as well, so that part of the mold has all the ridges. Then he molded the scarred side as an almost-completely-flat thing. Does that make sense?

Hmmmmm. Thanks, But how do I cast and preserve the Ridges? On the mold making tutorials I have Seen, You have to have a "Hole" Where you pour in the resin. Could you post pics of a PTK dollar edge?

You make a three part mold. One part is one face and the rim. Second mold is the other face. Their part is a section of the rim which also acts as the pour hole. Once you pour in the resin you plug it up and that creats the last part of the rim plus trims the piece out. Note: you must put this into a pressure chamber while the resin is curing and pour the right amount into the mold with just a small amount of flash squeezeing out the sides. Pretty easy to do but molding is tricky.

Sounds simple...sort of. Any pics of that process. And I wanted to do it in metal(something like solder) What kind of mold would be best for that?

Find a high temperature RTV rubber that can handle liquid metal. Might have to go with lost wax for best result. That's a whole different animal. Just get the original one you have and send it out to a jewerly company that will cast it up for you. Make sure you get the mold they make from your original piece or else you will and I will be seeing tons of these out there.
