John, the nuts can still be had in the UK and US - google "Sturmey Archer left axle nut". But shipping to NZ might not fit with the low-cost aspects of your project. Would it not be simpler to screwcut a nut on the lathe than to screwcut, gash flutes and heat treat a tap? Andy |
| John Hill:
It would be easy Andy but I would have to first make a threading tool small enough for 13/32" :scratch: I am also a bit wary of making a nut that might mangle the axle threads. I will be calling in to the local bike shop today, we are not usually compromised regarding parts for things like bicycles and he even managed to produce two crank cotters for me last week, so fingers crossed. :coffee: |
