Quite a while ago, woodcanuck did a Child's Lock Box with different hardware all over it.
He was my inspiration for this model for my two-yr. old grand daughter. I found out I hate doing hinges by hand! It has a key-inserted lock on one end, a hook and eye, a luggage latch, a padlock with keys dangling, a bolt slider, and two ring-lift trap doors at the top, plus a handle for her little fist. I was trying to use what I had or could scavange, but still spent $25 on hardware, then found I didn’t have the proper screws for many hinges, so it looks a bit strange, but she should love it. It’s 18”x 8”x 6”. Quite the little birthday gift, and I Thank You, Woodcanuck!
