My Recycled Chair
Transcript of My Recycled Chair
Why My Chair Is Stable
If you haven't already noticed, within my seat and backrest there are warren trusses. I decided to use this because the triangle shape distributes weight when under the force of compression.
For the base I cut up an old project board. Then, with my box cutter I cut a shape in accordance to the length and width of the seat. I folded and glued the shape then put in extra strips in the corners for support. Every piece I (except the back rest) connects to the base so it plays a key roll in this structure. This is the result:
cardboard (pizza boxes, appliance boxes etc.)
I used pizza boxes to construct my seat. First I cut off all the flaps on the sides then using a template I cut the widths that would be used to create each triangular section. I folded and stapled them to stay in place.
My chair is able to withstand the force of gravity and my weight so I know it's a stable structure. here is the final product:
As well as the triangular flap connecting the back and the rest of the chair. It acts as a gusset, resisting tension and compression forces.
Other factors contributing to the stablility are the legs. Short in length so the chair is low to the ground therefore having a low center of gravity.
heavy duty scissors
large metal ruler
twine and darning needle
Once I had enough I cut 1 inch slits at the ends of each of the pieces. Then I cut rectangular joining pieces also with slits, and used them to connect the triangles. once I had two layers I used the hole punch with the twine and needle to thread them together. This is the result:
For each leg I used three triangles (one slightly smaller than the others) and fastened them together with the wood glue. Next I held them together with rubber bands. Once they were dry I cut flaps at the top to attach to the base. once the base and the legs were together it looked like this:
Using the same method as I did for the seat I made the back rest. Then I made the back from a large cardboard sheet. It was designed to fold onto it's self and in between the seat and the base.The back rest would be tucked under a flap from the top. This is the back once it was finished:
Attaching the Pieces
Once all the pieces were made I attached them using ample amounts of wood glue. First the legs to the base, next the backrest to the back, then the back to the base, then the seat to the back. This was the result:
*taking the time to ensure the legs are the the same is important to ensure the load will be distributed equally
black electrical tape and stamp
For the decoration I used long strips of electrical tape and layed them diagonally from each of the corners. Between the gaps I placed a fleur de lis stamp. I did this for both the seat and the backrest.
