Convertible mbb to fbb part2

 

Bosses for V-brakes added.

Split in boom.

Adding 2 bracing tubes. There is a stick of aluminium shoved over the tyre as a heat shield.

After tacking support tubes into place.

Hi

Today I spent some time on this bike, and had done a bit of work previously, and now I am within striking distance of finishing the mbb part of this bike. The bottom bracket boom is now splittable and is braced from below. When I tacked up the bottom bracket bracing I was careful not to let the brazing interfere too much with the bottom bracket threads. 

With a bit of luck I will test ride tomorrow! Happy New Year!
