Step 3The Spool
Drill a pilot hole in the middle of the spool. This is vital as it keeps from splitting the spool, and works best on a drill press. You can make sure you're centering properly by placing the spool in a v-shaped holder. Make sure you are using a drill bit that is a size smaller than the nail.
Draw the rubber band through making sure it will be straddling the nail. I drive the nail in first just until I can see the point.
Drive the nail in leaving 1/16" or so above the surface, but make sure the spool rolls without the nail touching the ground. The nail performs two jobs. It holds the sides rubber band apart so it will wind, and it provides an anchor for the pull string.
Cut ~40 inches of thread. Tie a loop in the end of the thread and cinch it down on the nail. Use a spot of super glue to fix it in place. After the glue is dried, wind the thread onto the spool. While you're waiting for the glue to dry, move onto step 4.
