Handmade track dropouts.

Replaced the skyward-facing dropouts with new ones. The base is ст3пс steel, the overlays are stainless steel. Everything was brazed with 40% silver.

Technically, they’re called “track ends” - nice work though.

[u/atepernetuzh_ → u/Maybemmaybenot]

Yes. Thank you

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.

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

[u/atepernetuzh_ → u/shaaruken]

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

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

[u/atepernetuzh_ → u/bulgie]

Yes, I don't have a milling machine.

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

[u/atepernetuzh_ → u/produitbrut]

Thanks. I desoldered the old dropouts.
