Yes I am thinking I want a larger oven at some point.. and I have not even started PCing yet. IF I wanted a larger one and wanted to build it cheap what am I limited to? The only 220 outlet I have right now it 30A, so I assume that would limit the size/number of elements? Would this also limit the size of the oven? I was thinking of something that at least matched the size of the booth I made…. 4’x4’x4′. What are the basics of building an oven and what things do I need to consider? I don’t even know where to begin.
