ST/BB
This is where it starts. Miter the ST to the BB and build on from there.
Seattube angle
I opted for the proven 71 degree ST angle.
Front triangle mockup
After some careful measuring and filing, the front triangle was mitered up and ready for tacking.
Junction
This was the trickiest tube junction to get right. I opted to raise the seat stays slightly to make then clear the top tube in order to avoid "sandwiching". Hopefully this results in a stronger joint.
Seatstays
Seatstays nicely mitered to fit on the seat tube.
Chainstays
Another tricky miter due to the external butting on the BB.
Chainstay Scallop
Scalloped out the CS where it meets the dropout.
More Scallops
Made a matching scallop on the seat stays.
Stay Caps
Caps made from recycled crumbly tubing brazed on and smoothed out.
Capped CS
Capping on the CS meeting the dropout.
First braze
BB/ST/DT brazed. This was a fun join to braze.
Dropout
Finished dropout after brazing. Still not 100% cleaned up.
Finished frame
The finished frame. Still no paint or surface protection applied.
Headtube fillets
It takes a long time to smooth out fillets.

Dropouts
My favourite feature on this frame - the caps on the stays.
