All but brake cables are made from DIY lengths from a friend
who restores bikes professionally. The brake cables I make from
inner and outer I bought a long time ago from a place in Sheffield.
It is slightly larger than standard, enough so that standard ferrules
don't fit the abutments on brake and handlebar. I have a number of
ferrules made up to accept the cable at one end and to fit into the
abutment at the other although I've modified some of the handlebar
controls to take the bigger ferrules. The outer has a wire winding
which is much finer than modern outers and the inner is a much closer
fit too which means that nipples have to be modified as well.
All are soldered with a soft solder and an electric iron and I take a
lot of care with opening the inner wire end out to ensure it can't pull
The brake cables don't seem to wear anywhere nearly as quickly as the
modern cable - the handlebar nipple will wear before the inner.
On my wish-list: a solder pot and a tool to open out the end of the
inner - these have been described in other posts.
OK time to get the soldering kit out.
It may also be possible to buy nipples/terminals that have a grub screw or even 2 g screws that will fit the lever or pedal gear.
