Building a Mixte
Since it's been a while since I built a frame and since my wife has been hinting about doing a little more riding I figured it's time to build her a new bike. It's my first shot at a mixte and it's
coming out pretty good.
Nova CroMo butted tubeset, Everest crankshell and LS lugs. (package deal for $127, not bad)
1/2 x .035 4130 for the twin top tubes. The intermediate stays are
14mm tapered seatstays joined to the 1/2" tubes abeam the seat tube.
Upper head lug and seatlug started out as normal diamond frame lugs, now with the TT sockets
cut away and steel plates brazed into the openings.
Next come bridges, cable stops, eyelets etc. Fork gets built next week.
Final setup will be 700C wheels, SA 3sp. hub, upright bars, a stainless rear rack and
a kick stand (another first).
A few pics to start;

Beautiful. How about an "aft" picture of the top head tube lug? I think the only things I would have changed would be a plate for the kickstand rather than the reinforcements, and full rack/water bottle mounts.
Nice work.

A beauty! Thanks for sharing.
Funny my *first* build (arrgh can't wait to start) will also be a woman's frame, although fillet-brazed (except BB) and with a slanted 1" TT.
What did you use to replace the cut off sockets of the upper head and seat lug? Love the sleeved joints for the middle stays, and the kickstand plate!

The kickstand plates are stainless. There are 3 3/16" stainless pins brazed through the chainstays with about 1/8" extended out the bottom. The kickstand itself contacts the pins, placing them in compression against the upper plates.
This isolates the stays from clamping forces, should work nicely.
Full bosses and eyelets are on the way, after the brake, seat stay and top tube bridges.

no, he had a bike built. I think he really wanted a set of mixte lugs, didn't want bilaminate construction or modified lugs

Brazed the bridges, cablestops and bottle bosses.
Built up the rear wheel on the Sturmey hub, next is the fork.

Awesome work! I've been thinking of building a similar frame for my wife with geometry optimized for 650B

Update;
Frame is finished, all brazing and facing complete.
Started the fork yesterday, bent the blades, brazed the tips, brazed crown to steerer.
Tonight I'll trim the blades, fixture everything and braze them to the crown.
Then on to the rear rack, before paint......

Finished the last items on the frame, bosses for the rear rack and
built the fork last night. Tonight I'll start the rack itself.

In the first set of photos (on my computer) the frame looks like it is a metallic teal color.
I think it looks really good and am going to suggest that as a color when you come to paint.

Well, you're not too far off. The current thinking is a very pale metallic blue with cream headtube, DT and ST panels and gold lug lining.
That green came from the camera auto white balanceing against the red tile background.
