Can ya imagine just how stoked we would have been to have youtube
the first time we openend up a Sturmey-Archer Hum or a gear
cluster . A lot less lost ball bearings that are still lost today

I machined a custom Sturmey-Archer Hub Shell back
in the day! I also produced for a local hardware store custom
axle nuts for S-A hub Axles!

Back in the day if yer bike came with Mafac brakes it
also came with a little tool set maybe the size of a pack
of regular cigs . That little tool kit & Crescent
wrench were the only tools some bikes ever saw during
their lifetime after getting bucked in the bike shop . A
lot has changed in the bike world since I left it .

I have NEVER heard of anyone usimng machine tools to

Back when I was still into bikes &
Campagnolo ruled everyone had to use different
threads in their bottom brackets & pedals
. I had/have a Set of TA cranks & chain
wheels & the threads were different
between? TA , to Stronglite , &? Campy
crank sets . I was so pissed when my new to me
Campy blacktop pedals wouldn't fit the cranks
. It's actually probably good that I didn't
have a mini lathe or any lathe & mill for
that mater back then. I'm sure I would have
ruined a lot of expensive parts by fixing them

The
thing about bicycle parts is that they use
a lot of non-common threads and gear
profiles and screws with custom head
shapes, not to mention exotic metals and
tempering. ? for example, you can look at
a standard bottom bracket and find?34.92mm
diameter threads.? Not a hardware store
size.? You might measure and?think
¡°35mm¡± and be wrong. ??
I don't know the specs on
the gear you need but, there is a good
chance is it a custom-size or profile.
