I am finally finishing a too long project to add a second propane tank to my '90
Westy, and have a question for the metallurgists (or anyone who knows) on the list.
Yesterday I bought some 3/8" O.D. copper tubing to connect the two tanks, and while
the clerk was coiling it up very carefully, he said you don't want to work it too much
because it causes it to harden. He called it "work hardening". True or false??
Thanks,
Jerry
