Nice sunset Warren,
I have spent the morning so far working on one of my sinks. Finally got the plastic nut off that holds the ball in which lifts the stopper without breaking it. It has been on there since 1976 and was stuck so I went to the hardware store to make sure that Jim had some new ones in stock in case I broke this one. Then I got a pair of pliers and very easily tried turning it and finally it moved just a little and once that happened the rest was was easy. And for 5 minutes work I saved myself a $90 dollar plumbing bill.
