Sure. Another thing that might not occur before the fact. 
Leaky hot boxes work best. Don't seal or line anything. Raw 
wood, and some provision for air exchange and circulation. 
Some of the stability and control of the system comes from the 
heated air drying both the panel(s), and the box at the same 
time. The box becomes the buffer/reservoir. As I recall, you 
already have a working practical MC gage.
