I've been lucky enough to find a large quantity of 14 gauge stainless steel plain spokes in 305mm length at a very reasonable cost, with nipples included. Don't you love e-bay sometimes?

I'll be using some so I can rebuild an old pair of wheels - perfect size. There are enough spokes left to rebuild my other wheels that are awaiting a refurb, but the spokes are too long - I need about 290mm. If I could extend the threading up the spokes I could use them and cut off the excess after building the wheels. I know that professional spoke threading machines roll the threads onto the spokes from outside.

My question is - is it feasible to use a tiny die to cut this thread,in the same way as you use a tap and die set to thread nuts and bolts? I have some small dies but nothing that small. Does anyone know what the thread size and pitch is on this gauge spoke and if it's possible to buy a die in this size (maybe a model-maker's tool??)

I'm trying to do this as cheaply as possible so although it would be easier to a) buy the right length spokes or b) pay my LBS to extend the threading and cut the spokes or c) buy a spoke rolling machine and do it myself, all of these options are not feasible in my current pecuniary situation.

All positive replies gratefully received!

Thanks,
