1- What did you make? (Tell the story of what you made and how it works. Why did you use the tools and materials you selected?)
I created a wakeboard winch. A winch is a machine that reals in a long rope rapidly with enough power to drag someone across a body of water on a board. A lot of the materials we used were parts that we had laying around the house, and because of this we saved a lot of money. we bought the hose reel cart, chain, sprocket, and clutch. My friend Sean had the go cart engine and the Dollie and we had the sign and the rope. My friend Tyler had a welder and all the tools that we needed.
2- How did you make it? (Tell us where you got the idea for the project. Did you work with anyone else? Did your plans and ideas change as you worked on the project?)
Because I have spent my whole life in San Diego, CA, I have spent a lot of time in the water. I love to swim, surf, skate, and wakeboard. Last year I got really into wake-boarding but didn't have a ski boat. So I looked into other options. I saw some videos online of people getting towed by a large engine-powered machine called a winch. I loved the idea, and decided I would try to build one on my own.
3- Where did you make it? (Home, school, somewhere else? How did this connect to other activities in your life?)
We designed and built the machine at my house, my friend Tyler's house, and my friend sean's house. Building this winch gave me the ability to wakeboard whenever I wanted.
4- What did you learn? (Describe your biggest challenges and any surprises that arose during the build. What are you proudest of? If you had to do it again, what would you do differently?)
This Project was by far one of the most challenging things I have ever created. We went through many failed designs and dead ends. It took us six months to finish the project. Some of our biggest challenges included fixing the engines carburetor and oil leak, designing a kill switch, producing a solid base for the engine, attaching the sprocket to the spool. lining everything up correctly, adjusting the chain length, stabilizing the machine. If I had the chance to re-build this project, I would make sure that the sprocket and the clutch were aligned perfectly, and that the engine base would not budge.
Overall it was a fun project to think up and make and I couldn't be more happy with the result.
Step 1: Materials Needed
-Garden Hose Reel Cart
-6.5 hp Engine
-Centrifugal Clutch (8 tooth)
-Sprocket (54 tooth)
-Nuts, Bolts, and Washers
Step 2: The Frame
Step 3: The Sprocket
Step 4: Engine
Step 5: Chain
Step 6: Rope
Step 7: Testing and Riding
if you ride a boogie board or skim board push of the ground in shallow water to help the start. If you ride a skateboard or a surfboard, give a little push at the the beginning. On wakeboard, start on a slippery surface like a PVC pipe in shallow water.
Have Fun and Safety First!
