Description of final project
The final design for the Upcycled Benches consisted of aluminum street signs attached to a metal frame. The main materials used (street signs and plumbing pipe) were chosen to demonstrate the repurposing of materials through “upcycling”. The metal frame for both benches was made from ¾” galvanized plumbing pipe. The pipes were custom cut to fit the length and width of the street signs. The pipes were connected using “T” and “90” connectors and flanges were attached to each leg to enable them to be bolted into their permanent location. Each joint was tightened fully except for the middle bars that made the seat of the benches. In the case of the middle bars, each side was tightened only half way due to the fact that you can not make a closed loop unless special connectors or backwards threading is used. To improve the strength of the bench and the half tightened bars, each joint was then welded on either side. The signs are attached in multiple ways. The signs that make up the seats are attached using pipe straps for the back 2 bars of the frame and bolted through the pipe on the front bar. The seat signs are recessed to create a smoother edge for the user to hang their legs over. The signs that make up the back of the bench are bolted through the pipe frame in multiple spots instead of using pipe straps.
Prototyping
Figure 1 shows our first prototype. This prototype helped us to figure out the layout of the signs and that the Bike Lane signs needed to be raised to create a more comfortable back support. Figure 2 shows a small scale of the Bike Lane Bench. This prototype helped us to roughly figure out how the frame of the bench would fit with the signs. Figure 3 shows our Autocad of the frames of the benches. This prototype took into account actual lengths of the pipes. Figure 4 shows our last prototype before building. This prototype was originally supposed to be the beginning of the final product but in building we learned that when making a closed loop with piping, a special connector or backwards threads are needed. This lead us to our decision to weld the joints.

Testing Results
The upcycled benches can support a number of individuals and can withstand the punishement of middle schoolers. It is currently placed at Zane Middle School.

Schedule
- Every 2 years
- Welded joints must be sprayed with Cold Galvanizing Compound Spray to prevent rusting.
Instructions
This is how to maintain. The step by step how to template {{How to}} is most likely best for this part.
