outamatches,
the oven plans i posted in the beginning of this discussion are similar to DDs, except the stove has wire hinges, similar to a spiral notebook.
I built one in a afternoon, using just tin snips and drill, a little easier than cuttiing tab slots if your not handy with your hands? Just drill a few holes and thread some wire.
I'm taking my flashing stove this year, but if that doesn't work as planned, next year it will be the reflector oven!
And, YES, the whole top folds back to get at or check the item baking.
Plans are $5, but that's cheap in the scheme of things ;)
