What you'll need:
- Appropriate molding (I forget what mine is called... but it has a wide round channel cut into it perfect for holding balls)
- Wood for the sides
- Wall anchor hardware
- Woodworking tools and wood glue
- Juggling balls! (For those curious, from bottom to top: bounce balls, contact & glow balls, stage balls, vinyl balls, homemade russian-style balls [play pit balls half-filled with salt])
Step 1: Design It!
I went through many iterations of possible designs, initially planning to include hooks/holes for clubs and rings, or explore some sort of weave-ish aesthetics where the shelves intersected in complicated ways.
In the end, I decided to keep it simple in order to maximize the available storage and let the balls shine through. It's important at this stage to use graph paper and actually draw to scale in order to take into account how much clearance you want for each shelf, as well as the amount of wood you'll need to produce a particular design.
Once you're happy with your design, go buy the wood (always get a bit more than you think you'll need) and do a bit more testing/figuring to determine the optimal parameters. I tested out the angle I had in mind and the rough size of the final product with the setups shown in the pictures. Everything looked stable and appropriately sized, time to start cutting!
