A few dozen years ago, I went to an auction with some friends of mine. They were looking for political memorabilia but I was just looking. The auction came up for a tomato bushel basket filled with these doorknobs and locks with the section of the door still attached. So I bid and I got them.
The first thing I made with them is this hanging shelf above my claw-foot tub in the downstairs bathroom. I put this together in the same way as I will describe in the next few photos. The board came off the front porch when I replaced a few damaged sections. The paint was there. I sealed it with 2 coats clear exterior poly to keep the paint there, and to protect the board from wet hanging towels.
First I took the door knobs apart and away from the lock sets. They just unscrewed under the ceramic knob with a small flat head screw.
I found a wooden dowel that fit into the base of the doorknob. Then I drilled a hole into the wood where I wanted the knob to go.
Cut a short piece of dowel rod and pound it into the hole with a hammer.
Add a drop of wood glue and slip the knob onto the dowel.
Hang finished panels. This is the corner of my back porch. I needed a spot to hang longer coats.
Instant coat hanger.
Assembly time - 10 minutes. Drying time - 2 hours. Hanging time - 5 minutes.
