I put the knarp at the caliper and use a standard brake cable in the original Raleigh cable housing and threaded adjuster (Although you could replace the housing with new material at this point since you are using a single-ended cable and it all is apart).
A spoke nipple above the knarp keeps the assembly from falling apart randomly on you leaving you with no brakes and replicates the Raleigh-branded lower "knob." If you shorten the nipple a little you can still pull it out of the caliper when you loosen the cable adjuster so that you can remove the wheel without moving the knarp.
