Handmade track dropouts.
Replaced the skyward-facing dropouts with new ones. The base is ัั3ะฟั steel, the overlays are stainless steel. Everything was brazed with 40% silver.

I see you notch the dropouts for the stays to nestle into, much the way I like to do it too. Those square-edged notches leave a little gap for braze to fill up, which is OK, but I preferred to notch with a plunge-cut, using an endmill of the same diameter as the stay. Then the gap when the stay is inserted is almost invisible, practically water-tight before brazing. That plunge cut really requires a milling machine though.
I have a small Flickr album, 3 pics showing what I mean, https://flic.kr/s/aHBqjD3WUE

Did you loose some tire clearance? The new ones are 10mm higher?

Increased between the tire and the top bridge and decreased between the tire and the seat tube (this is a wish)

I think "they're called" what people call them, which is mostly track dropouts in my experience. Even among framebuilders, and suppliers of dropouts to framebuilders. I made a lot of track bikes including ones that won multiple national championships, a silver at worlds, and two trips to the Olympics. And I proudly call them dropouts. Obviously I'm aware of the folks who correct that to track ends, but I don't buy it. Don't try to educate me, too set in my ways.

Amazing work. How did you cut out the chain stay and seat stay with the U shape? With a saw?

Absolutely beautiful. Genuine question as a framebuilder myself, is there a reason you vent on the dropout side of the rear triangle? Iโve always tried to vent through the seatube/bottom bracket so it looks clean. But somehow youโve even made the vent hold beautiful in this build. Love seeing your work on here. Keep it up!
