3/4" that would do it ! :fing32:would like to learn any tips on how to secure it.
heavy chain, through the frame, and anchored to a 12" diameter, 4' deep concrete pillar embedded in the ground. When I mean heavy chain, I mean 3/4" link-rod diameter.
they could always torch it off, or hacksaw it, but when they see chain this heavy, they'll just walk away.... most thieves are lazy.
