A friend of mine asked me to help her out with making these small “boxes” (loose interpretation, I know) for a conference coming up next week. The boxes will hold 13 nails each that are used for a teambuildibg activity. It’s an old brain teaser, where you try to balance as many nails as possible on the head of a single common nail. When balanced correctly, you can get all 12 nails to lay on top of the head of the main nail.
The actual build is fairly easy for these. I used some extra 2×8 pieces I had laying around, planed the top layers off and cut the blanks to 1-1/4”x3”x6”. Using a wood clamp, I fixtured the pieces on end and drilled the two 3/4” holes into the end grain using a long spade bit on the drill press. The hole depth is roughly 4”, long enough to fit the nails. The end cap is fastened with a 1-1/4” drywall screw right in the center so it can pivot to either hold or release the contents of the box. (Pic 1)
Pic 4 shows how the main nail should be placed in order for the participants to begin balancing the remaining nails.
Pic 5 shows the lot of boxes, with my original prototype showing the solved puzzled (middle, top).
I do have a couple pics of the solution, which I may post after I know some of you have tried this! Thanks for looking, dont forget to check back again for the solution. As always, comments welcome.
