Step 20: Measure and Cut the Chair Back Slats
You'll need (7) chair back slats. These are tapered cuts. I made a simple (yet dangerous) taper jig out a sheet of masonite and a few smaller pieces of wood.
You can simply mark the board from the measurements below and use a circular saw to rip the taper.
I marked the length approximately; this is a good place to use some of your less than perfect boards. Anywhere from 34"-36" should do fine. As you'll see later, we're going to trim the tops to make the fan shape at the top of the chair.
