I was introduced to a car welder who loved projects, and handed him the design. We my basic drawing which i had interpreted from the reading of some interenet documents and a large amount of confidence.
The metal box that returned, was not glamerous. It was industrial! but did this industrial beast get hot?
Yes it did, so much so that the 3mm steel sheet that had been rolled to form the rocket, was glowing red hot. That is an impressive 550 degree plus!
when this heat was direct onto the floor of the steel box oven, did the bricks get hot?!
