This was a pair of driveway gates. They swing just fine without the springloaded wheels that I bought for them. 3” thick, with 3/4” thick free floating boards. Solid backer board in the groove in the sides to allow the panels to expand and contract. I dried the boards in my shop for several months knowing that PT boards shrink a lot. They still shrank a little. The fence rattles a little with the wind as the panels are not nailed in, just set in tracks. Polyurethane construction adhesive with stainless steel screws. I’m going to run copper flashing across the top to help it last, especially since some of this is end grain. The side gates were mortise and tennon, but I didn’t want to bother on these. They are half lap in a way -You can see the different direction the frame boards are going in from the front as opposed to back view. The handles are square tube steel painted black, offset from the face using round tube steel.
When I hung them, I ran ratcheted straps across the tops of the posts to put tension on the posts, then hung the gates. That was just in case there was differnt flex between the posts. My theory is that if you just hang them expecting a 1/4 drop or something, one post may flex more than the other. It has been 6 months now, and the difference between the tops at the center joint is about 1/8”, so I count that a big success considering the material.
All horizontal surfaces have a 5 degree slope to shed water, and between the middle and bottom rails, there are channels cut in the center to allow for drainage for any water that hits the face and runs down into the grooves cut for the panels. Several hundred pounds each. It was a real trick hanging them by myself, but I like the challenge. Lots of wedges, clamps, and straps. 16’ across, and 6’6” in the center. Half of the ellipse was drawn on the floor at Home Depot. I used the concrete lines in the floor to assist me. Drew it out, then took the sheet with my arch drawn on it and checked out. Check out my router lathe if you want to see an even crazier challenge.
