I too am always looking for ideas as I get older and know downsizing is
sooner rather than later forcing me to move and shed my M2 rotatable pair.
I've been slowly working on building double Moxon's for 440 and 2 meters
both using #6 copper wire and trying to measure very carefully. Another list
Sand it to shiny copper and lay on some paste flux.
Even then, you'll need a lot of heat. Make sure the solder flows on,
and not just globs on.
I have not built a Moxon but I have dealt with soldering heavy wire.
Let us know how they work out for you, after they're up.
