Anvil calculator for TerraFirmaCraft and TerraFirmaGreg
The forging calculator solves TerraFirmaCraft’s anvil. Pick a recipe and it finds the shortest sequence of hits, draws, punches, bends, upsets and shrinks that lands the work exactly on the target and ends with the strikes the recipe’s rules ask for.
The calculator runs in your browser and needs JavaScript.

How the anvil works
Every anvil recipe has a target between 40 and 113 on the work bar, picked from the world seed. Each action moves the work by a fixed amount, and the item is finished by the strike that lands exactly on the target while the last three strikes follow the recipe’s finishing rules.
The actions: Light hit −3, Medium hit −6, Hard hit −9, Draw −15, Punch +2, Bend +7, Upset +13 and Shrink +16.
Going below 0 or above 150 destroys the item, so the finishing strikes have to be planned before the first one. That is what the calculator above does. The anvil guide explains the rules with a worked example and lists the rules of every TerraFirmaCraft item; more guides cover ores, rocks and structures.
