my bad luck

You guys all motivated me.

My son and I have a wall cabinet with a drop down front that forms a work table for our shop manuals and for working on small parts. In the down position it's still high enough to open over the front fender of a car parked in the garage. I've been eyeing the rear hinges suspiciously thinking that if the screws pulled out, the rear of the shelf would drop onto the fender. We don't often leave it open but it would be just my luck. I added safety chains on the back edge today after mulling this thread all day while working out in the garage.
