Ironworker/Manufacturing Instructions

Introduction
See Ironworkers for introduction.

Sketchup of prototype 1: 

Note: Prototype 1 Capacity is actually 45 Tons, because the main arm was too thin to withstand warping from pressure. The holes for the main pin, and linkage pins egged from punching holes above this rated capacity. If this arm, and the linkage attaching it to the punch were 1.5" thick, the capacity would jump to 60 tons.

Build
We start the build of the open source ironworker with a 120 ton hole puncher for poking up to 1.5 inch holes in 1" steel (figure based on Edwards ironworkers) plate.
