It was definitely “humble beginnings“ for me to learn how to make cook pots. I had never brazed or welded before and most of my building experience is with wood. Below are 20+ of my unsuccessful attempts when I was still learning. To make things even more difficult I was experimenting with all kinds of different designs. The first ones I made make me laugh out loud at myself and hopefully can give a few of you a laugh as well Finally I asked a friend for guidance on how to braze and presto - they are pretty easy once I learned the correct process.Unfortunately the answer is no to both questions.
This is why this thread is so long and people are discussing so many aspects to creating these devices.
The controller is actually not that hard to wire up.
The challenging part, at least for me, was creating the bowl and nozzle.
Then the next challenging part is just getting all of the right sizes of various things and making everything come together correctly. I have several wrong size band heaters sitting around and several wrong size cook pot/bowls as well. Wrong size is maybe not the right way to think about it. Lets say they were all part of my learning mode experiments.
So it is not really a "plug and play" type of project.
