Was gonna make some polycarbonate Chambers, trying to decide thickness (1/2"?) and size (12"x24"x1"high). Cut them into stackable rectangles. Then I’d put these pads between each layer to provide infrared heat to the top and bottom. Was thinking each chamber would run me about 60-80$ and hold about 40g? The best part is I can just stack a near unlimited amount and the put valves on a ballast. The modular design would let me turn them on/off one by one as each was ready. Hoping it would be able to hit 28" mercury of vacuum, with etoh evap at around 30-40c.
Anyone built anything like that? I think it would be 1/2 the price of an oven setup.
