Maybe it is not just the heat impact to the wood, but also the conduction through the glues that bind the plys that leads to the plywood conforming to mould? The RF makes the wood more pliable through heat. The glue then heats to a more malleable state and it actually acts as a lubricant between sheets allowing the individual plys to confirm to the mould. Then when the RF is removed, the wood cools, the glue cools and the ply re-solidifies in the newly assumed form. So it's not really just the wood that's conforming; it's the glue that facilitates it. Interesting to see the impacts to just wood alone. Time to get a bigger microwave.

Just a thought . . .

: Hi Dean;

: About the only thing RF could do to wood is heat it, which would correspond
: to my experiences with heating and locking strips and panels in place. An
: RF chamber that found the wood as a lossy dielectric could probably do a
: far better job of heating the wood uniformly and to a sustained higher
: temp than my hot-air gun . . . ;-)
