Hope all is well as the new year approaches. I have been reading posts of oven builds lately and decided to go ahead and build one for powder coating since I have been doing a lot of that lately using a tabletop convection oven. The oven I would like to build is not very large since I wont be baking anything larger than maybe a car rim (huge maybe). I am looking to throw something together with the dimensions of 3' L x 18" W x 2' H.
The question is will I need a blower in this oven to make it convection? I opened my convection oven the other day and I never did notice a fan built into the board. Even when you press the convection button you cannot hear a fan turn on or anything, I still wonder why they call it a convection oven. I really would like mine to circulate the air all throughout the oven when its turned on, but since you folks are the experts I am asking for ideas.
In a regular kitchen oven you have burners on the top and bottom of the oven. In my little convection oven for powder coating there is also a burner at the top and bottom. The oven I want to build I don't know if the burners should be at the top and bottom or just place them on the sides at the bottom.
