I am curious about the Epoxied anchor bolts. Do the instructions have you
drill the holes for the bolts and epoxy in a way that the hole in the
concrete, is lined up in the direction of the pull? Or is the axis of the
user drilled hole, NOT collinear with the force exerted? Can the bond of
the epoxy and its smooth walled hole in the concrete withstand the stress?
Actually, I think the bolts themselves have some sort of a sliding wedge
expansion feature too, which would also share a piece (maybe most?) of the
force exerted... Just curious...
