Tim,

OD is the usual.  Sounds like we are in the same line of work.  BTW, the
sign-off at bottom is generated by my work email system and not an attempt
to sound pompous or all-knowing.  I should have removed it prior to sending
the previous message.  As I did this time....

Hi Steve,
Thanks for the response. I understand what you're telling me. What I need
to know is - when someone on the Tesla list says "use 3/8" tubing for the
primary", do they mean the industry standard 3/8" tube size (that has an OD

of 1/2"), or do they mean "use tubing that measures 3/8" OD" (which would
actually be industry standard 1/4" tubing).

(Not trying to be a smart***, just letting you know that I -do- know about
copper tubing...)
;-)
Thanks for any info/assistance,
Tim
