This is my version of a classic way to “roll” the die for a board game. The key to making this special die agitator is the clear plastic capsule. I found the right size, 2″ diameter and 1-7/8″ tall, in a vending machine — it’s the kind that holds inexpensive toys or trinkets.

You will need:

  • Plastic capsule, 2″ diameter
  • Die
  • Compression spring, 3/8″ diameter, 2″-long, .035″ wire diameter
  • Wood, 1/4″-thick and 3/4″-thick
  • Flathead wood screws, #8×3/4″ (4)
  • Finishing nails, 1-3/4″-long, small (4)
  • Electric drill and drill bits
  • Hole saw
  • Saw
  • Hammer
  • Screwdriver

Project Steps

Cut the wood and drill the holes.

Parts A, C, and E are cut of 1/4″-thick wood, while parts B and D are 3/4″ thick. Cut all 5 pieces to 3-1/2″×3-1/2″.

Holes have to be drilled in all pieces except part E.

For part A, cut a large hole in the center, anywhere from 1-7/8″ to 2″ in diameter, depending on the size of the domed half of your capsule. Then drill 4 countersink holes about 1/2″ in from each corner, for the wood screws.

For parts B and C, cut a 2-1/8″-diameter hole in each center. These holes will house the bottom part of the capsule. For part D, drill a 3/8″-diameter hole in the center, which provides a guide for the spring.


Nail together parts B through E with the finishing nails, avoiding the corners where the screws will go. After this bottom block is assembled, insert the spring. Place a die into the capsule, snap it, and lower it into the wood block. Part A will cap everything. It requires a slight push to keep it in place as you screw in the wood screws.

After that, you’re ready to go. Good luck!
