Folding chairs are very convenient to have around the house, in your RV, or even in the boot of your car. There are plenty of different materials that folding chairs can be made of, including wood, aluminium, even plastic. As convenient as these folding chairs are, they aren't the most attractive pieces of furniture. To find out how you can make your own wooden folding chair, and one that is more attractive than most folding chairs, follow the instructions below.
Use your handsaw to cut the board into two pieces--a longer piece that is 51 inches long and a shorter piece that is 40 inches long.
Trim 2 inches from each side of the longer board starting 15 inches from one end and extending all the way to the other end. The result should be a board that is 15 by 11 inches and then 7 by 36 inches. This piece will make the seat and the back leg, or support, for the folding chair.
Trace the thinned end of the longer board in the centre of the shorter board 15 1/2 inches from one end. Find the centre of the board that will be traced onto and the centre of the board to be traced and line up these two points before tracing.
Drill a hole inside the area that you just traced so that your jigsaw can fit inside this area to cut it out.
Cut out the slot that you just traced using your jigsaw, making sure to cut away enough so you can slide the thinned end of the longer board through at an angle.
Slide the two boards together and try your chair out.
Redefine the angle of the seat plank. Since the boards won't intersect at a right angle, you need to trim the back part of the seat where it rests against the other board so the two boards can rest flush against one another. To achieve this, draw a line from the upper corner of the side edge of the seat downward. The line should run parallel with the back of the chair.
Trim this small wedge of wood from each side of the back of your chair's seat so that the seat can now rest flush again the back of your chair.
