Started off with a modified home oven but when it got busy the small oven and having to do parts one at a time started sucking and taking too much time. I have been building this custom oven for the last couple months and I am just about ready to fire it up. It is 3X3X3 I.D. Made from 2X2 steel tubing, Fire rated insulation between the 16gauge innder skin and 18 gauge Galvanized outer and a large dual layer of tempered glass.. Anyway, here she is.... I just have to mount the controller and elements!
