My welding and fabrication skills are minimal, and I was able bust out this bad boy out of scrap, donated springs and lead, and some industrial surplus. It has completely changed what I can do in the forge.
When I’m not using it, I disconnect the treadle chain and the springs pull the head up and out of the way of my ~1835 Mousehole, allowing me to switch back and forth from hand work to treadle work almost effortlessly.
