Took a break from the ‘32 to try something different.
This was an experiment to see if I could wrap the steel house numbers I built last year with copper; I want the natural green verdigris finish so they pop out instead of blending in. When I first built the marker I intended to get the steel copper plated but couldn’t find a shop interested in doing them. So, this was a $20 experiment that I can fix with a flap disc if it didn’t work out.
First order of business was to pull the numbers off the monument and clean them up. The 1/4 “ all-thread standoffs are just friction fit into 1/4” holes so they were easy to remove. A coarse Scotchbrite disc in the M12 grinder took all the rust and scale right off.
I did the first number (6) with dead soft 28 gauge copper sheet just as it came from the vendor. ( ~$5 each for a 6” x 6 “ sheet delivered from Amazon)
Got it done but had quite a bit of spring back, so I annealed the rest of the sheets before cutting and forming.
Used a propane torch and a quick quench in a bucket of water- what a difference, it really made it a lot more pliable. Marked and cut the pieces out with snips.
Worked the copper sheet around the steel numbers with a little Stanley 2 ounce ball pein hammer and an old flat head screwdriver blade . Even with annealing I did get a few small tears on the edges but I was able to solder them shut. Also had to put a couple of soldered tabs on the 8 because there wasn’t any way to close the inside of the curve without snipping through the edge. Had to use the same repair technique somewhere on every number because the copper wanted to tear on inside corners.
Ended up with some solder on the edges, but none on the faces after a quick pass with the Scotchbrite disc.
I sealed the back sides of these with a skim coat of Big Stretch Urethane caulk to prevent moisture getting in between the bare steel and the copper wrap.
Gave them a quick polish with 00 steel wool and put them back on the monument marker to weather out.
Time will tell how these are going to hold up.
