Homebrew PCBs

I just had an idea, how about instead of the cloths iron use a couple of
fairly thick (0.25-0.5) steel plates, and put it on the stove top. With
the paper and board sandwiched to provide the pressure, this could be
set up as you want it, then 'cooked'. After a little experimentation you
could accurately see how much pressure is needed (by varying the weight
of the top plate) I think it would eliminate a lot of the guess work
inherent with the iron.

Would this work?
