<p>[QUOTE=&quot;imrich, post: 1311398, member: 22331&quot;]<b>A GREAT Post!!</b></p><p><br /></p><p><br /></p><p><br /></p><p><b>Thanks for the enlightening link, as it appears that many have little understanding of the practical coinage and </b><b>equipment development </b><b>process.</b></p><p><b><br /></b></p><p><b>I believe one will find that a static hydraulic press capable of producing the ~300+ ton force imparted in normal coinage production would require an ~9 inch diameter cylinder when using an operating pressure of 10,000 pounds per square inch. The general operation would be relatively dangerous, slow, horsepower intensive, generating significant amounts of heat in power transmission. Complicated voluminous expensive power accumulators can optimize the utilization of the hydraulic operation. Those having used a large hydraulic press (e.g. 4 inch cylinder operated at 1500 P.S.I.), maybe splitting Elm, might realize the relative requirements of a press requiring ~35 times that power. </b></p><p><b><br /></b></p><p><b>It will probably be determined that the modern equipment was initially of European design/manufacture, as was partially documented in your referenced link. The process, relatively, is a low horsepower input, high kinetic energy stored mechanical impact operation. This operation allows considerably great number of cycles per unit time when using proper tooling components, lubrication, and pro-active maintenance.</b></p><p><b><br /></b></p><p><b>I believe the article properly defines the relative complexities in just remobilizing an existing piece of equipment.</b></p><p><b><br /></b></p><p><b>The subsequent post of the relatively more primitive mechanical process requiring specialized tooling/coin-materials, a hearth/foundry with energy&nbsp; source, and an agile assistant, might produce coins of the caliber shown when simplicity/economics dictate coinage technology. </b>:thumb:[/QUOTE]</p><p><br /></p>
