Saturday and let ya hit it WB. Takes about 120 PSI to break a 1"x12"x10" pine board, bet you can do 3 of them all at once, Specially when I've hit 9 at one time before. heck, I hit 11, 8" x 16" x 2 1/4 " concrete patio blocks all at one time and broke them. Got a nice twitch in my shoulder now though. LOL Tore something
