have any of you ever built a wood drier using black poly and 2x/s?
I had a "Handy Man Club of America book/mag (yes member herer) ) it detailed how to build a solar powerd one. which used heat gains and airflow from the solar heat gain to dry the wood at a rather quick pace compaired to standard air driing!. If anyone is very interested I think I maybe able to pull a link to it or post a scanned photo of the unit .
basically it is made using dimensional lumber frame around the wood pile, slanted black poly for roof and sides, with air space at lower front (South side) and upper rear (north side) with sides closed to near ground level. wood up off dirt is a given. keep the poly tight by bending the 2x2 frames slightly UP and stapeling the bent up edges similar to installing a window screen. bend them slightly (use weight and blocks so that the frame forms a U shape (the U is more of a dish shape and staple the sides that are the uprights. lay down blocks say 1" across two sides then weight the center so it dishes up then attach poly to the sides where the blocks are and remove the weight. when the weight is removed from the frame center the poly is pulled tight. twist the frame 90 degrees and repeat to make very tight... add center braces only if needed... errect the frame over wiht air spacea ll around the ploy covered frames. leave frames in contact with the ground all way around EXCEPT for the 2" gap at south side bottom and 2" gap at north top side. angle the roof so HOT air rising form south runs up and along twards north side opening. 20~30 degree roof angle is best if i remeber right so you will have ot make a longer north wall than south wall by that distance. north wall can be covered in clear if you want. others said the clear sun on wood was better for roof and south wall, BUT the mag said black absorbs the heat better and creats more air flow
anyhow hope that was awaste of no ones time.
