My kids had some how knocked the top of my coffee table off, and I had the idea to put a secret compartment on it before I put it back together, I just needed the right bracket system. I went to my local Habitat for Humanity Restore to look around for materials and found this awesome locking swinging latch for $3!! It had a bracket to mount it to something and another to mount to it. It also locked in it's open position and in it's closed position. I had another system in mind but once I had the swing arm I knew what I was going to do with it.
Since I don't have a garage or shed to work in and this is Canada with -25 weather, I didn't get a chance to sand and re-stain the top for this instruckable(but I will be come spring).
For this design I used: 1 coffee table, double locking swinging latch, hacksaw, 1" narrow hinges, glue gun & glue, drill bits(1/16, 3/32, 1/8), drill, small wooden box, pencil, Phillips screwdrivers(2 sizes), small ratchet with 9/32 bit, 3 nuts & bolts, 3 locking washers, 6-1.5" wood screws, 6 1/4"wood screws, 6 washers.
Step 1: Fitting Everything Together
Once I had the the top and side support off, I made sure the swing arm would fit and work properly without any restrictions. The wooden support bar was 1/2" and rubbed on the swing arm, so that had to be cut down to an acceptable thickness. I traced out the perfect spot and the screw holes to brace it to the bottom of the top part of the coffee table. I also used a small cardboard box to get the dimensions for the actual box I would be using.
Step 2: Making the Cuts & Drilling the Holes
Step 3: Time to Build
I used the nuts and bolts to attach the box to the swing arm with locking washers. All that was left was to attach the top and stash my goods! You can see my hand on the locking latch.
