This is my version of the Large Modern Porch Swing. I did a couple of things different. I wanted a nice finish so I cut everything to length then did 3 coats of high gloss exterior paint. It feels pretty indestructible and I know it's covering all the surfaces well.
Since I painted everything ahead of time and I liked the finish I thought about the screws and nails and was able to assemble it using only screws and having none of them visible. I pocket drilled most of them, although without a jig so they're actually toenailed. The seat slats are screwed down with angle brackets underneath and the back slats screwed from the back side. That way there is no need for finishing nails or wood filler.
Other than that's it's pretty much to plan. The structure we have may have been for a swing at some point so I had a pipe to attach to. To be extra safe I doubled up the rope and used a pedigree cow hitch. It's very sturdy and if and one line breaks there is another piece as a backup.
I'm really happy with how it turned out. Out of all the porch swings I've seen this one best suits our style and taste.
