I have maybe ten 3 x 10 x 8' beams I got from a construction site that read at 17% moisture content.
I want to dry them further, and also kill any bugs.

Can I sticker them inside a plywood box that I paint black and place that in the sun?
With a hole at each end for venting?

I don't think I need to make a solar kiln, but I want to run it by you guys who know more than I do about this.

Thank you, Mark
