So against my better judgement, I was convinced by a buddy to build him a new road bike with a bb86 shell. Main reason being he wanted uber oversize tubing (38mm dt/31.8 st/tt, 44mm ht) and wanted the bb to be in proportion. I did my best to keep the heat down while welding the bb, but alas either warping or just the undersized nature of the shell has left me with a bike I can't get a bb into. I've searched the internet and haven't had much luck finding an off the shelf reamer/facer. Anyone have any insight as to an alternate method of reaming the bb shell or where I could find a tool?
