1/4" copper tubing is 3/8" OD.... if you're going to use Ø 3/4" tubing for flue tubes, you had better bore a Ø 7/8" hole for it.

not disagreeing with you, just making an observation

Too many things going on to bother listing them.

The designation or use is the key to the whole thing, not to say that a plumber cannot use refrigeration tubing or vice-versa but it is certainly sad to order a few hundred dollars worth of 3/8" tubing and find that it is 1/2" OD. The two rolls of copper on the left in the HD photo are 1/2"OD.
I never spent too much time doing plumbing, only when I was forced into it but sizing what you're working with is down right important. It's also important to refrain from changing hard fast and obvious rules.

My local Ace Hardware sells the coils of heavy wall tube. A long time ago I bought one coil each of 1/4 and 5/16 and still have a lot remaining after piping two locomotives.
