The detail that grabbed me straight away is the long foot pedal lever of rectangular steel tubing running along the workshop floor. UrsaMajor has built a hands-free, foot-activated door for a gas-fired forge: press the pedal and the sliding door plate rises, step off and it settles shut again. No hand is needed at any point in the cycle.
The structure around it looks properly thought through. There is a welded steel frame carrying a hearth of pale refractory firebricks, with the burner assembly and fuel tank sitting on the floor to the left. The door travels vertically along guide channels, hung on steel cables that pass over top-mounted pulleys to counterweights. Bent linkage arms and steel handles fill out the frame, and the upper housing is dark steel with a heat-tinted finish that suits the whole setup.
The circular refractory inserts set into the door plate are a nice touch, and lifting the door to reveal the active glowing orange flame inside is the payoff. A bright yellow painted support rack on the right and insulated wall panels with tensioned cables on the left give the rig a proper workshop-built character.
One open question for me: since letting go of the pedal lowers the counterbalanced door, the opening seems to stay clear only while a foot stays down. For long heats that could ask a lot of one leg, and I would be curious whether a hold-open position might come later. Even so, the cable-and-counterweight action alone makes this a very tidy piece of smithing.
