[Shop-talk] Is this a shutoff?

Wait...you did your air lines in copper?

This is the part where I tell you no matter whether you're using type L or
M, eventually it will fatigue and explode. Copper shrapnel everywhere.

Yes, you *can* use copper. You can use Sch. 80, too, and you can use
soldered copper on gas lines (I've got a house full of it now, in fact).

(The benefit of black iron for air to me has always been the thermal
capacity of the pipe. But then again, I worked two feel from a Sch. 40 air
line for a few years in college. I'd never suggest anyone do that, but it
always does temper my panic about things somewhat.
