Rethreading a bottom bracket

viscount + sheldon + google = http://www.sheldonbrown.com/lambert.html

There were some other oddities, such as press-fit cartridge bearing bottom brackets (the spindles have a tendency to snap at the circlip groove), and what appeared to be a TA pattern crankset with a Lambert/Viscount-specific large chainring (an aluminum plate with large round holes cut out of it; distinctive and quite attractive in a way). It was unusual to find cotterless cranks on bikes in this price range at the time. Most of them, unfortunately, used a badly designed crank/axle fitting with a non-tapered square fitting, rather than the normal tapered square.
