Black Lego pieces have carbon in them, which is why they don't bleach (see
colour debate elsewhere). I wonder if this makes any difference to friction?
I don't think there's any difference when I cut up grey or black parts - they
all make a powdery mess! I make axles of length 1, 1.5 and 2.5 studs and
shorten the grey connector pegs with axle, for steam engine rods.
I do find that not curving the ends of my cut axles gives more surface area
inside the wheel and therefore more friction to stop wheels coming off. The
grey connector pegs with axle that I cut are the oldest ones with the most
friction - newer pegs with axle in grey, blue and tan all have less friction
than the old ones from the late '70s.
