At about $25 for ten feet of 3/4" copper pipe, plus lots of time to put
it together, why bother? I have made short sections for matching and
the like, but wouldn't consider trying to make a long run of it. I do
still have some scraps of 1" thick Teflon from when I helped make a
quarter-wave length of 22 ohm 6-1/8" flanged line to go from 50 ohms to
10 ohms (five 50-ohm ports in parallel). Wow, that was a long time ago
now.

Cheers,
Tom

Hardline is good stuff, right? Does anyone make their own out of
copper water pipe?

Seems doable, but have never heard of anyone doing it.

This is what happens when I have too much time on my hands. :-)
