ST/BB

ST/BB

This is where it starts. Miter the ST to the BB and build on from there.

Seattube angle

Seattube angle

I opted for the proven 71 degree ST angle.

Front triangle mockup

Front triangle mockup

After some careful measuring and filing, the front triangle was mitered up and ready for tacking.

Junction

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

Seatstays nicely mitered to fit on the seat tube.

Chainstays

Chainstays

Another tricky miter due to the external butting on the BB.

Chainstay Scallop

Chainstay Scallop

Scalloped out the CS where it meets the dropout.

Made a matching scallop on the seat stays.

Stay Caps

Stay Caps

Caps made from recycled crumbly tubing brazed on and smoothed out.

Capped CS

Capped CS

Capping on the CS meeting the dropout.

First braze

First braze

BB/ST/DT brazed. This was a fun join to braze.

Dropout

Dropout

Finished dropout after brazing. Still not 100% cleaned up.

Finished frame

Finished frame

The finished frame. Still no paint or surface protection applied.

Headtube fillets

Headtube fillets

It takes a long time to smooth out fillets.

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