The Abacus Bracelet

Picture of The Abacus Bracelet
Want to go retro with your calculator watch? No, not the 1980s. How about two millennia before that? We're going to make a bent wood bracelet with a miniature, working abacus built into it! 

These instructions are for a traditional Chinese Suanpan style abacus with a 5+2 bead configuration, but you could easily adapt them to a Japanase Soroban style with a 4+1 bead configuration.

Step 1: Tools and Materials

Picture of Tools and Materials
  • Wood veneer
    You'll need five pieces approximately 1.5" wide by 8" long. The wood I used is bubinga from Rockler.
  • Wood glue
    I used Titebond III wood glue.
  • Superglue
  • Seed beads - size 8/0 (approximately 2.5mm diameter)
  • Head pins - 21 gauge silver, 2" long
  • Aluminum sheet cut from a soda can
  • Baking parchment
  • Clear gloss polyurethane wood finish
  • 2x4 lumber - 3" long
  • 2 hose clamps (minimum 2" diameter)
  • Screwdriver (to tighten the hose clamps)
  • Coping saw
  • Sandpaper, assorted grits
  • Metal ruler
  • Scissors
  • X-Acto knife
  • Tweezers
  • Wire cutters
  • Small brush to spread glue
  • Pin vise and a bit the same diameter as your head pins
  • Power drill and a bit wide enough for your coping saw blade to pass through
If you've got access to a band saw or jigsaw it'll make step 2 go a lot faster, but it isn't required.

This is great, I love it's quirkiness. This would be perfect for my Grandaughter who has Aspergers Syndrome and needs to fiddle with her fingers all the time, it helps her stay grounded. I couldn't make it but I admire the skill.
