Anybody have a suggestion for how I could make one of the boxes "locking" ....to meet state gun carry laws? Not sure it would meet the law, but gotta start with getting it locked first.

What if I drilled a hole in the lower part of front lid, and one in the base, maybe I could get a padlock or one of those circular padlocks.....
guess I need to check out some lock sites and see what shapes there are. Gotta be something more elegant than that....
