Week 3 - BB & Seat Tube
We received our frame kit this week, unfortunately I wasn't able to photograph the whole kit together as most components were still parceled up. Would have been pretty cool to have all components together on one picture, but oh well!

The BB lug has been manufactured via a cast and therefor required some slight alteration to allow the seat tube to fit nicely, it would fit with a good amount of manipulation but this tight of a fit wouldn't help when it came to brazing.

Filing, checking, filing, checking.... 10mins later

Next job was to profile the other openings within the BB onto the tube, quite simply with a permanent marker. The BB threads are going to be re tapped at a later time due to all of the Flux and brass that will cover them.

Over to the welding/brazing area of the workshop. Lots of flux added to remove all of the offending grease/general shite on the lug and tube!
