Thanks for that tip Tom! It's brilliant. A ball wouldn't require strict alignment.
I might even give it and the tinning a try on Chris's '15 Harley.

Rick: For the seats I have soldered a bearing ball to a rod, coated the ball with grinding compound and lapped the seats by hand. Tom

Well I thought I might have a solution to the leaking part. I spun up a fixture in the lathe to hold the valve by the threads and took .001" cuts at 45 degrees until any nicks or grooves were gone. Looked really pretty but when I put it back together it still leaked. Must be some flaw in the seat..... I'm thinking maybe I can make another fixture, that will screw to the valve body and hold a small Dremel tool burr or stone in alignment to dress the seat inside.

The handles on mine are different. One is like a clock key handle and the other is just a piece of sheet metal brazed to the valve. Obviously a past repair.
