My peel is 14" wide, I generally get skins stretched to 11 or 12". Maximum 2 at once, always finish by 4 minutes, usually 2.5 minutes. (caputo only) Portable in the sense that I would like to build it in the shop and move it to the backyard and put it on a stand. Some finish work could be done at that point if necessary. But not portable like put it in the back of a vehicle and go cook somewhere. As far as cheap, I don't know. Cheap in the sense that it isn't an all brick wfo, but otherwise not. I already have everything to build a copy of his oven, except for the fibrex blanket, and may need a few more firebricks. I'd like the general shape to be similar, with the exception of the exhaust and front fascade. I could even firebrick in the end opposite of the front door if needed. Thanks.
