In the world of production Open Die and Step Down Shaft Forging, blacksmiths will take a piece of metal, heat this metal for a set time and temperature until it is red hot, before it is rotated, hammered and carefully elongated in unison to reach a specific shape or size.
The starting piece of metal, sometimes called a "Blank" or "Mult", can be tricky or time-
Use this Reverse Forging Calculator to save your blacksmithing operation time and money.
For example: If a "Blank" is cut too short, all the heating and hammering time will be wasted when the final part cannot make its finished size. Having said this, if the starting piece of metal is too long, then everything left over gets cut off and scrapped, including the extra labor and heating time. All that energy usage, labor and furnace real estate can be vary costly to throw away and, again, this is why this program was engineered.
Easily use this software to help calculate the starting length of the piece of metal to achieve your forging goal with minimal waste. Once you calculate your "Blank" size, click the E-
