I picked these up a year and a month ago and just realized I do not have a build thread in here. I spent the last year trying to find parts for this thing, finally gave up last month and just started making parts that would work.
the bottom bracket is the problem, it is not remotely close to any standard. I started with a stronglight type chain wheel and cut this to use as a crashring. I found an odd size set of cups in a German bike that were small enough to fit in here
then i filed a couple of adapter rings to fit in the bottom bracket
polished these up and i finally had a starting point to make it a rider
