When I built this rack, it was perfectly square, the saddles were all tight, and it didn’t move at all. 3 months later, I guess the pressure-treated wood has shrunk and it’s sagging.
So what’s the right way to build something like this? Just let the lumber sit for several months to dry out? Don’t buy from Home Depot? Is there a way to tell when the wood is “ready”?
Thanks. The plan to fix it was to basically put shims into the joints as a temporary method to square it, and then add some additional braces.
I designed this assuming specifically that the square cut joints would be strong enough, which was obviously wrong. But it does seem like the joints have expanded, or the beams have shrunk. Or both. Because each joint was a tight fit when I built it.
