After checking the pressure of the Oxy and Acetylene, time to play with fire! Uniformly heating the area concentrating more on the BB as this was thicker than the seat tube, once the tubing was glowing a cherry red brass was fed into the joint and manipulated throughout.
Unfortunately at this point we rang out of time and I had to stop for the evening, within the BB there is 360deg of brass but significantly more is required at the top surface

Lots of cleaning of the joint required this week to remove the excess burnt flux and brass!
