drain is leaking where tail piece screws into drain receiver - pipe is 20 gauge, and has fine threads. joint was made with Teflon tape. Slip joint at intersection of tail piece and overflow tee.
I believe that Teflon tape should not be used on fine threads; copper pipe to brass fitting.
It may also be leaking because the receiver was not backed with a wrench when the strainer was screwed in - I've broken the 24 gage tail piece at the threads before - the reason for using 20 ga.
So the questions: should Teflon be used on brass to copper pipe - fine thread connections?
And: what do you do when you cannot put a strap wrench on the receiver and you have to tighten the strainer?

When fine threads (or any threads) are for mechanical attachment only - not actual sealing of any joint - IMO this would be a good place to use "Plumbers Grease".

Never thought of using plumbers grease on threads, only used on moen and other o rings.

I always put a light smear of dope on the threads(no tape). The strainer shouldn't have to be tightened so tight, that the drain body needs anything more than to be handheld.

I am not really understanding your question. It is NOT copper to brass, but rather brass tubing into a brass fitting. IF this is the tubing out of the tub drain, why is it separate? That is a connection usually made by the manufacturer. When I DO have to seal a fine thread, I use the same pipe compound that I use on pipe threads.
