on the subject of drying pecan, i too have had less than desirable results. years ago when i had an ind. saw for me i told him to saw some pecan in 1/2 thicks boards. i buried them in my drying shed and they promptly rolled up into i am not sure what. since i have sarted sawing i have sawn all pecan extra thick, and also sycamore too. those are my two worst wood to dry.
