So you took the measurements of your lift and transferred it to a piece of steel, traced the bottom plate on the steel, then drilled the holes where it would mount, then placed it where you wanted it, drove the allthread in, removed your jig, poured the concrete, cut the excess allthread when the concrete cured, then placed your posts directly on the protruding bolts which lined up perfectly?
That is awesome. Wish I would have thought about that.... I planned my pad to include thicker concrete where the lift is going, but you did it right. I commend you on that one. Never have to worry about it pulling out of the concrete. You did put a nut/washer on there that was embedded in the concrete to keep it from pulling out didn't you?
