Well I plan on building a 9x7x6.5 oven but I was wondering if it would be possible to make it 110v? Also how many elements will I need? Anymore info about building something of this size that would be helpfull? I know, I have searched and things like that, mainly I’m just looking to see if something this size is able to be made with 110v power. I’m going to be using r-13 3.5 inch thick insulation. With a layer of 22g sheet metal covering that. Thanks!
