Had some time to work on the fork this week. The fit up on the crown was a bit on the gappy side, so I went with 50N silver instead of my customary 56%.
56% flows faster, melts at a slightly lower temperature, and I just generally love working with it.
50N is a bit thicker, and a bit more sluggish. It has a few advantages: it will fill larger gaps, it will form small fillets for strong joints on brake bridges/other high stress braze-ons, and I'm told that it wets out more easily on stainless steel than some other silver alloys.
The downside is that I just haven't gotten the hours in with it to feel totally confident when it's necessary. I ended up doing a second pass to make sure I had good penetration, and definitely crisped some flux near the end (should have let it cool down and re-fluxed it instead of heating it right back up).
That said, I think I'm going to stick with this one. I was able to draw the silver through to the pins, and I think it's unlikely that I have a bad fill.
Here's the crown all cleaned up. I love Henry James' crowns, they have this beautiful elegance to them. I can't wait to see it with some paint on it.
I also love hourglass spindles. I set these up to work with Nitto/Rivendell's Hub Area Rack. It's a gorgeous piece of gear. I can't imagine actually needing four bags for the kind of riding that I do... but WHAT IF?
Worth mentioning: I used 50N for these rack mounts too. Note the nice little fillet around the base of each of them.
Here's the whole thing. It needed a bit of a twist, but I've gotten it pretty straight.
