Our team, Team T.A.L.K., made a bench with recycled snowboards for the "Rectangle of Doom" at Zane Middle School (Eureka, Ca). It was designed and built from February 2021 to April 2021. Our motivation to solve the problem was to create something that looks good and is useful that could sit in front of the school. The intended users of our snowboard bench are the students at the school, as well as the teachers, faculty, and even parents.
Background[edit | edit source]
Catherine L. Zane Middle School located in Eureka, California, caters to a large and diverse population of students. Humboldt State's Environmental Resources Engineering Department and Zane Middle School have worked together to tackle different projects on Zane's campus. As of Spring 2021, the "Rectangle of Doom" is a large space located in front of the gym and other academic buildings, where students get dropped off and picked up before and after school. The students will walk through the space and track mud and dirt throughout the rest of the campus. Zane Middle School wants this space to become an aesthetic and safe place for their students. Trevor Hammons is a counselor at Zane Middle School with an interest in solving this problem. He has worked with a number of teams who have tried to come up with solutions but few have been successful so far. Previous teams tried using planters and benches, but students continued to walk through the plants and the benches had sharp edges, so both were deemed unaesthetic or unsafe, and removed. Only a few previous projects worked out, the Human Sundial being one of them. It is still present in the "Rectangle of Doom" today. The other projects that succeeded only take up a small portion of the Rectangle, so there is still a lot of space to fill. The Rectangle has recently been paved.
Problem statement[edit | edit source]
The objective of this project is to make a bench out of recycled and up-cycled materials that will be safe for students and adults to sit on. It is also to change the aesthetic of the "Rectangle of Doom" and to make it nicer and prettier.
The criteria listed in the table below provides the standards Team T.A.L.K. needed to meet in order for the project to be considered a success. These criterion were talked about with the client. Some criterion are more important than others, like safety and aesthetics. Team T.A.L.K. worked to incorporate all of the criterion, but some had more weight than others. These criterion helped steer the team in the right direction to make something that will last a long time at Zane Middle School.
|Safety||How unlikely it would be for students to be injured by the project, use the project as a weapon, or block the line of sight of staff members.||10|
|Aesthetics||How appealing the project is to look at.||10|
|Durability||The amount the project resists destruction and the length of time the project retains its original quality.||10|
|Low maintnence||The amount of time and energy spent by maintenance staff on the upkeep of the project for the lifetime of the project.||10|
|Cost||The total amount of money spent on the building and implementation of the project at the middle school.||9|
|Ease of implementation||The level of skill required to build the project, the cost of shipping or otherwise transporting the components, and the number of people needed on site to implement the project.||9|
|Not difficult to remove||How much time, energy, and money would need to be spent to remove the project from Zane in the case of project failure.||7|
Prototyping[edit | edit source]
Our first round of prototyping included many different ideas for what could be put into the "Rectangle of Doom," but that was before we knew our objective on what we were building changed. Our prototypes for benches are the following images. Before we started prototyping, we drew up what we thought a backless bench could look like (shown in the image below). We learned from this drawing that we didn't quite like the slabs in the middle. We would have rather had them on top, or not there at all.
In this first-round prototype, we learned that a bench looked good in the "Rectangle of Doom."
The image below is from our second-round of prototyping. One of Team T.A.L.K.'s members made a life size bench to test out function. We learned that we liked a backless bench.
The image below shows another of our second-round prototyping. A cardboard model of a backless bench was made to test function as well. We learned that we had to proportion everything right, otherwise the bench wouldn't look good.
After building these prototypes, we honed in on what we wanted our bench to look like. We hadn't exactly designed the bench with snowboards until this point, but we were still able to mess with the position of them. The image below shows our AutoCAD drawing for the front view design of our bench. The curve at the top represents the snowboards. We learned that the snowboards look good upside down.
Final product[edit | edit source]
The final bench was named The Not A Bench Bench. It is a simple wooden bench with two upside down snowboards bolted on top. We used a total of 13 wood pieces to build it: 4 legs, 4 planks for a top structure, 3 planks for a bottom structure, and 2 small boards for in between the top structure. The two snowboards used are old reused snowboards. The snowboards were spray painted the school colors of red and gold. We also spray painted a falcon design on one of the snowboards by using a stencil.
An image of the final product is below. It shows the bench at Zane Middle School sitting on the "Rectangle of Doom."
The image below shows the underside of the bench. It can be used to identify which planks are being referred to in the Instructions.
The spray painted falcon design stencil was made by one of Team T.A.L.K.'s members, Alice de Lescure. Zane's school mascot is a falcon, so we wanted to include that in our final product. We spray painted this stencil onto the gold snowboard because we thought it gave a nice contrast to the solid colors.

Operation[edit | edit source]
This project is very simple to operate, there is really only one thing to do. Sit! See Troubleshooting for any quick questions about the state of the bench.
As shown in the image below, the place to sit on the bench is on top of the two snowboards.
In the image below, Mr. Hammons, the client, is showing what to do with the bench by sitting on the bench.
In the image below, two of Team T.A.L.K.'s members are showing what not to do with the bench by standing on the wood structure.
Maintenance[edit | edit source]
The only maintenance for this snowboard bench would be to reapply Spar Urethane finish to the wood every 2-3 years and possibly remove stickers or other forms of defacing every year.
Schedule[edit | edit source]
When and how to maintain the bench.
- taking time to remove stickers or other forms of defacing.
- Every 2-3 years
- reapply Helmsman Spar Urethane Clear Satin finish to the wood structure of the bench.
Instructions for Maintenance[edit | edit source]
This is a plan to maintain the project. The brief step by step instructions and images detail how to take care of the wood structure of the bench:
Conclusion[edit | edit source]
Testing results[edit | edit source]
After testing the bench by standing, sitting, and even jumping on it, Team T.A.L.K. is pleased with how the bench came out. By standing on the bench structure, the team proved the bench is sturdy. We were worried about how the gap between the snowboards would feel, but after sitting on the bench, we found the bench is very comfortable.
Discussion[edit | edit source]
Team T.A.L.K. is confident that the bench is safe for middle school students to use. Even though we don't want them standing on or jumping off the bench, the bench is sturdy and strong enough that it will not fall along with the students.
Lessons learned[edit | edit source]
Some lessons that were learned were that snowboards have funky shapes. Next time we would plan for a gap between the snowboards when they were joined at the ends. We would also consider getting two different sized boards, or offsetting the snowboards so there are no gaps.
We also learned that we need to take more pictures. Next time we make an Appropedia page we want to be prepared with photos.
Next steps[edit | edit source]
The next step for this project is to wait for the concrete to be poured into the "Rectangle of Doom." Once the concrete has cured, the bench will be installed atop it. Some of Team T.A.L.K.'s members have discussed visiting the bench once it has been put in to see if it looks good and meets certain criteria.
Troubleshooting[edit | edit source]
|Wood starts to chip or splinter?||Get a 120 grit sanding block to buff it out.|
|Snowboards loosen from bench frame? (very unlikely)||Tighten the eight screws that attach the snowboards to the two middle wood cross-pieces underneath the bench. These screws will be found in pairs in circular depressions on the underside of the seat area.|
|The spray paint chips?||Let it be. It will make it look more like a recycled snowboard.
Could also get Rust-oleum Painter's Touch 2x Ultra Cover Clear Gloss to protect the remaining paint.
|Whole bench falls apart?||Call a cleaning crew to get it removed from the premises.|
