So today I was thinking about how to solder a stainless steel ball to a guide piece, without getting silver solder on the working valve portion of the ball. We're talking about a 5/32" diameter ball (4mm). I didn't have much faith that I could manage a strong butt joint to thin wire, or keep the solder masked properly. Then I thought of a possible way to do it with strip brass, so had to try an experiment: Spotting with 1/8" drill -- new valve seat also shown: |

The ball in place. The real question was whether I could solder something this small without getting solder in the wrong place. |
vtsteam:
The setup for soldering. Flux paste and a tiny sliver of silver solder. I decided to heat from the bottom, as I was sure my torch would blow these bits right off the brass strip: |
vtsteam:
It worked! :ddb: I did have to steer the silver with a tiny bit of wire because the flux boiled and moved it away from the ball. But it did work. Here's a close-up outside in stronger light: |
