I have wanted to work with molten metal for quite a while, It is one of the myriad hobbies I have always wished to pursue. I had a taste of it when in High School, we were able to melt aluminum and then machine our pieces in the lathe.
I stumbled down the rabbit hole on youtube a few months ago watching people melt aluminum and other metals in home foundries with propane or waste oil and was mesmerized. It seemed like anyone could make a cheap one and use it, but the more I watched and learned the more I realized most of these were just falling apart after a few melts. I wanted something that would last for many pours. Then I found a set of videos that a fella had put together outlining his build and documenting the steps. I chose to model my foundry after his.
