The picture (below) shows our model, with pencil to scale. The lever arm on the right side of the press moves up and down, which in turn moves the horizontal beam downward to press the briquettes, which will be plunged inside a 3" PVC pipe in the full-scale press. The model even has the full range of motion that our full-scale design will have (see video).
With this proof-of-concept design under our belt, we will be building the first full-scale press in the upcoming days after Spring Break. Stay tuned!
