[QUOTE="NeonBlurb, post: 2198525, member: 74855"]...On second thought... Again, all this hinges on weather I correctly understand what the OP wants to do. Get yourself a used rolling mill that can handle the thickness of metal that the coin you want to squish is made out of. This takes care of item number 2 I listed above: the strong thrust bearings and it also takes care of the frame. Then all you need is a machinist who can do the engraving in a hardened roller for the design you wish to impress into the surface of the coin. <--NOT CHEAP Things to consider: The typical penny press takes a single pass to reduce a penny's thickness by more than half. Rolling mills usually take many passes to squish metal that much. You may have to have two sets of rollers--the first set rolls your starter coin thinner and thinner over a few passes. Then the second set of rollers has the design that you want to impress. Also, rolling mills typically roll out long bars. You are starting out with a coin (not a long bar). You may have to design a carrier/holder to get the coin started in the rollers. On thing you DON'T want to do is get your hands anywhere near the rollers. This is probably a costly undertaking and a bit odd but that doesn't mean it shouldn't be done :-)[/QUOTE]
