Without it, your round deck is not going to be as good looking as you'd like it to be.
So while you're still in the planning phase of your deck, including curved rails to the layout will make a huge difference. Here is how to go about making round deck rails.
Install the Headers
Headers are the very outside edge of your round deck rail. They are sometimes produced from bits of deck wood and need to be laid out between each exterior joist, making sure the headers protrude somewhat. Use 3-inch screws and fasten the lay out with your screw gun or drill.
Drill a Hole in the Center Joist
This is going to be the core point for your trammel. A trammel is a part of wood using a hole on both ends. One end gets anchored fromthe hole using a nail, but it must be freely able to turn. The other side has a hole for a pencil. It's basically a strong compass, and by rotating your trammel, it is easy to size up the roundness you would like for your deck, just as a compass would do on a sheet of paper.
Arching the Wooden Railing
Laminating together four strips of 1 1/2“ x 3/4“thick cedar plywood with a heavy duty outdoor adhesive is one way that wooden, round railings are made. Other options involve soaking the wood and holding it to the proper curve as it dries or simply mounting it when it is wet. Both options can be done by you with the help of clamps or screws that hold them in place while slightly curving them to form the round shape.
