Above, you can see my final sketches, measurements and plans for my Yo-Yo. I need to use the lathe in the FABLAB to create the round shape of a Yo-Yo and the saw if I can’t find rounded pieces of scrap wood.
Materials needed:
- preferably 4 circular pieces of scrap wood
- 50cm of string
- 3mm wood cylinder
- wood glue
Plan
Day one:
- Draw sketches
- get measurements
- saw wood to correct sizes
- glue wood pieces together
- prepare the rest of the needed materials
Day two:
- sand down wood pieces so the edges are all even
- drill hole through the middle of each piece
- measure the 3mm wood in the hole
- begin using lathe to round out the wood pieces
Day 3:
- finish rounding the edges
- sand until same weight
- once both pieces weigh the same amount, push the 3mm wood cylinder in one side
- tie the 50cm string to the side with the cylinder
- push the pieces together
Success criteria:
For the Yo-Yo to work, both sides of the wood need to be equal amounts of weight on either side. So, as long as both sides weigh the same and look even the Yo-Yo will work. This is what I will base my success off of.
