Try turning the stove upside down, wire the pan to the burner and stick a steak up there.Brazen wrote:Interesting. I've always cooked with the heat UNDER the pan...and I'll be darned but the food was warm all the way through. I guess it must just be kinetic excitation at the molecular level...anyway, I guess I have to turn the pan upside down now and find out for myself. (I don't care, I think I'm hilarious).
It should fall down when its cooked.
So don't stand underneath it.
Probably won't work for french fries.

You don't even have a legit signature, nothing to reveal who you are and what you do...
Best of luck to you. (uneva)

I did my second pair yesterday. Flat mold, bottom heat, ramped up fast and took out hot. They came out with 16 mm of camber.
The first pair was ramped up over time and then stayed in the press overnight to cool - and ended up with +1-2 mm of camber. So it seems that the slow version is working better for me.
My press is buildt of wood with a wooden cattrack so everything gets more or less the same temperatur after a while. I baked the first pair for 4 hours on 80 c from the bottom and the top veneer got up to 70c during that.
I don't have the money to buy another blanket, nor the time (right now) to build my own, but do you think it would work to heat up the bottom to max temp (in my case 80c, I work with west system) and then take the casett out, put the blanket on top, into the press again and heat the top up until it raches 80c to get a more precis result? or does the whole package have to have the same temperatur at the same time, so to speak?
in other words. Is it peak setting temps that has an influence on the contraction of the fibers, or temperatur difference when you cool them down?

I would try heating from the top on your next pair. The epoxy will "pull" in the direction of the heat, so if it's a flat mold you may get a small reverse camber...16mm on the bottom is more than I have ever experienced from one-side heating. Wow. Also, I've never had good luck leaving things in the press under pressure to cool, but that's just me.
