Today I finally got to build a rocket forge that did not end up working. This was towards the end of the schedule and uncle mud seemed to be juggling too many projects, so for several days I helped him to get a chance to play with a forge. Uncle mud is fantastic to work with by the way, I enjoyed joking around while getting stuff done.
I ended up taking a fire brick core with a metal feed tube and placed it into a cut off end of a 55 gallon drum and filled it with sand. I then took insulated fire bricks and stacked a heat riser with a window at the bottom to stick the metal in. I then wrapped the heat riser in ceramic blanket. The hottest it got in the window was around 1100 °F, it was hotter in the coals at the bottom of the feed tube (1250 °F). As I was burning, Paul walks by and says 'want me to shit on your design', so I have that to look forward to as a dinner discussion. It is not my design, but it was quick to build and I have learned quite a bit in this experiment.
