I don’t know quite how to explain this, but I’ll try with the help of a photo.
I posted earlier about had a problem I had with the deck screws breaking in my trellis and I’m now wondering if it was actually an expansion problem. I cut a 3/8” deep dado in my redwood frame to allow for expansion, but I did not think about contraction during the winter months at 18°F.
I was just working on reinforcing it when it occurred to me that it is possible for one side to pop out if it were cold enough and expand enough in the hot sun to break the screws.
So I was thinking about centering the plastic lattice inside the frame with a couple of screws in the center to keep it centered and still allow for expansion. I’ll need two screws so that the lattice will not rotate and I’m concerned that the expansion might be too much for the screws when the surface temperature from the sun goes over 130˚F. I’ve never measured the temperature, but I know that I can’t pick up anything metal in the summer sun without burning myself.
Any other ideas to keep the lattice panel centered without the screws?
