Secure stacking storage for stops

To keep my drill-bit stop collars organized, I drilled two ⁵⁄₃₂ " holes in a ³⁄₄ "-thick scrap wood block, one of them only ¹⁄₂ " deep. Into the through hole, I drove a 16-penny finishing nail from the bottom up, then rounded its point with a file.

To store the collars, I slip them over the nail starting with the largest, and secure them using the set screw on the top collar. The hex key stores in the stopped hole.
