I wanted to do something a little unique to secure the drawer in place, without using traditional latches, so I came up with some retractable pins. I bent over some 1/4" brass round stock to make two canes, and fitted them into the rear wall of the drawer in a dado. There are holes on each side to allow the rods to protrude, and a spring in the middle to provide tension. Eventually, I would cut down the pins to fit and would cover most of the dado with a cap to keep the rods inline with the holes as they're squeezed together, otherwise they want to slide up into the top of the dado near the middle.
If your first cut is too short... Take the second cut from the longer end... LBD
