I like my towels to be completely dry when I need them, but I'm not a fan of traditional towel bars. So, I sat down with a pile of towels and a bundle of copper plumbing pipes and came up with this design. There's enough space to fully hang-dry two regular-sized bath towels, a couple of hand towels, and a shelf for what-have-you.
To cut each piece of copper pipe, measure and mark a cut line on the pipe, using a pencil or marker.
Slide the tubing cutter over the pipe, aligning the blade with the cut line. Tighten the knob on the bottom until it is snug—enough to hold it in place but not so much that the cutter can't be rotated around the pipe.
Turn the pipe and, with each revolution, tighten the knob a half turn. Each time this is done, the scoring mark should become clearer.
After a few revolutions, the copper should come apart easily.
Shine the copper with steel wool.
To join the pipe segments to the fittings, apply the glue in a thick ring on the inside of the fittings.
When joining the pipe with the fittings, give the pipe a few turns to more evenly disperse the glue.
Join together six pieces at 2 inches, two pieces at 30 inches, and four T-fittings, as shown.
Add two 90° elbow fittings to the front and two T-fittings to the back, as shown.
Add to the back two pieces of pipe at 7 3/8 inches, one piece at 30 inches, and two T-fittings.
Add to the front two pieces at 7 3/8 inches, one piece at 30 inches, and two T-fittings.
Add to the top four pieces at 2 inches, four 90° elbow fittings, and two pieces at 7 3/8 inches.
For the legs, attach two pieces at 12 inches, two end caps, two T-fittings, and one piece at 30 inches.
Add two pieces at 26 inches.
Set aside the copper to let the glue dry.
Sand the 1 x 8 with an orbital sander.
Use a piece of sandpaper to "break" or slightly soften the sharp edges.
Wipe away all sawdust.
Apply one coat of polycrylic finish.
Once the polycrylic finish is completely dry, center the copper assembly on the board.
Attach the copper assembly to the board using four copper tube straps and 1/2-inch screws.
Flip the rack over and attach to the legs. Bask in the glory of your accomplishment.
You can attach this rack to your bathroom wall with 8 to 12 1/2-inch copper tube straps.
