Here this past summer I cut 16 foot 4x6 white oak and laided them down on 16 inch centers then layed 2x12x16 foot on top looks good but did shrink and every now and then I drop a wrench between them. So I made me a magnet on a stick and pull them out, and before anyone ask its nothing like soap on a rope
But ruff sawed lumber is hard to slide on so thats where the tin comes in
But as I look back on my life , life is good now it use to be tin in the open. Wind blowing so hard you had to wear goggles to keep your eyes from watering so bad. See what you southern guys are missing
This morning 7 degrees under the truck adjusting the brakes no gloves 7/16 inch wrench you got to love it
