I'm anticipating trouble. Any hints? PB Blaster a waste of time?

I figure that I'll need to some Scotch to get through this.

I've been through this, but only a 45 year old plug. I even tried an
air powered impact wrench without success.

Drill a hole in it and saw out to the edge without damaging the threads
on the socket side.

Don't try excessive force on it as you'll likely do more damage to other
old pipes and fittings.

Replace with a new plug.

Have a martini.
