Handywork? All he did was take the fitting that connects a TA chainring to the crankset, grind it down to fit the freewheel, then affix a few extra chainrings to it.

Something tells me that the overhang would likely not go over too well on a 27" wheel or on a wheel built with reasonably narrow-spaced spoke flanges - chances are he was running with a 559mm/26" rim that had some reasonably significant dishing to it.
