Hello everyone, I have a 1200lb 120cm modular oven arriving in two weeks and I need to design a mobile base for it. Ideally, I would make the base out of steel, we do have a welder at the farm but the only one who was really gifted with it, passed away last year. I don't trust the welds of anyone else to hold my precious oven (except a professional welder of course, but that gets very pricey). If the style of welds for a pizza cart can be made so that they are extremely easy, let me know, I would prefer that way.
My other option to consider would be a wood cart, I know wood is no where near as rigid as welded steel but I have some wood-working experience and I think it is possible. In some ways, I am more comfortable working with wood because it is a medium I understand. I could make the base out of 6x6's and set the oven on 2x6 joists with 2x4 cross bracing to strengthen it from lateral loads.
I have picked out some 10" pneumatic tires on casters rated for 500lbs each to wheel it around the property.
My next issue to tackle is insulation, I want to do this as cheaply as possible, I do not have hundreds of dollars to throw at several ceramic blankets and insulated bricks for the hearth. I would just do a vermiculite/portland base using a 5:1 ratio but I am concerned about the strength of this in a mobile application. Do you have any input for a cost effective insulated base for a mobile oven?
For the dome, I was thinking of just getting a single ceramic blanket and covering it with 6-8" of rock wool. I heard that rock wool can stand up to more heat than fiberglass insulation, with the ceramic blanket taking the brunt of the heat, the rock wool wouldn't be exposed to nearly as high of temps. It is my hope that this would be a superior insulation to vermiculite/portland and weigh much less as well.
My last item is the exterior housing, I see most people using steel frame to build the roof and sides, is there a reason that I couldn't use wood after all of the insulation I will be putting in there? I know there are clearances that must be maintained depending on the situation, I am open to input here though. I have never worked with metal studs so I have no idea what is involved with that.
Thanks in advance.
