This tandem came in for a dust off and lube up last week. It was purchased at a local auction years ago, and then traded so it seems unlikely to ever trace the origin, which is too bad because this is not your ordinary custom tandem.
The builder cut the back end off a bike and the fork off another bike and welded them together here, leaving the headset and steerer tube in there to hold the stoker handlebar.
Welded a tube between the cut off chainstay nubs.
And secured that tube to the bottom of the back bike with a proper big fat old weld. The back end of the tandem was pretty low, but no problem, just cut a piece of the Ashtabula out and re-weld the crank arms back together, they measured about 155. The timing chainring was the existing on the rear crank, but a drive chainring was added by welding another chainring onto spacers. Rickety? You bet. Kick ass? You bet! The owners want it to roll around the neighborhood and it will continue to do that for sure, this was fun to work on. Mostly :)
