Would love to see a picture of your heat treating set-up.
Sorry, I don't takes pictures other than for photo IDs or insurance purposes. I might change that practice if I ever actually do any real worthy experiments in bow making.
It's just a 2x4 with some small curved blocks screwed on top. The bow is clamped on top of blocks, belly side up. Then I put on top the silicon heating strip, a thin silicon pad mat, than a heat pad neck wrap to weigh everything down a little. I also use the built-in thermostat of the heating strip and a push button digital timer with auto shut-off. I usually turn the heat on at 170°C for 20 or 30 minutes.
