i just ordered this so i can test if a spoke is in fact 1/8"x40 tpi at a 55' angle.
Did you receive it? Any results?
Thanks

ok.  so i put a BSW (Whitworth) thread gauge to the threads of the spoke and there is no fit, as i suspected all along, the thread pitches are unique to spokes and nipples.  i'm pretty much convinced the fellow on sohc.4 knows exactly what he is talking about, the pitches major and minor thread diameters are different as well as the pitch count which is on account of the threads being rolled and not cut.

i would suggest getting a sacrificial spoke or more as needed, some thread cutting fluid and a Rowe spoke wrench, put the sacrificial spoke in a vise and see how a nipple responds to the test.  then test the "cleaned" nipple on a non-sacrificial spoke.  unless the zinc is really globbed in the threads, i think you'll have success without too much effort.  i've used this method with good results in the past.

 In the DimDarks in Merry old England there was a thread used on Bikes both push and motor called Cycle Thread, Which the closest thing to it is BA . The reason they had different threads on there motor cycles was so you had to purchase spare bolts etc from them. Maybe the spoke thread size is a result of this . It is only a thought .

I do not understand because there are too many technical terms... Huh Huh
What is the problem on the spoke? The thickness of the zinc plating?

Yes. I have had some plated that were a bit tight.

Anyway, I have given up on trying to find a tap for the spoke nipples. My plan is to first soak the nipples in a rust remover. Then I found some small brushes that fit in the nipple. I tried it out on a couple by running the brush in and out with a reversible drill. It cleaned them out real nice. When I can finally get around to doing them I’ll send them out for plating. If any are a little tight I have some “spare” spokes that I can run in them try to clean them out. Not sure what else I can do at this point. Funny thing is I got steel and brass brushes. The steel one disintegrated on the first one. I don’t know if it was defective or the bristles were too stiff. But it looks like the brass one will work just fine. Here’s a pic of the brush.

Hi I have just had two sets of spokes and nipples re-plated  and the rear wheel dressed up perfect but when it came to dressing the front wheel all the spokes would not even try to enter the thread in the nipple after a lot off head scratching and phone calls and enquiries on thread sizes etc I was approached by a retired motorcycle mechanic who told me to clean up every single spoke threads using my bench grinder with a wire wheel attached.The result was perfect. Which I assumed was just slightly removing some of the plating thickness.
Hope this works for all out there.

Mark, i assume you are using nipple grease before threading nipples to spokes.  fwiw, Buchanan's sells the grease specific to threading nipples to spokes.

Hello Mark, Wink Have you fixed this over-thickness problem?

Sorry to say that I have been too busy to do much of anything. I haven't gotten my nipples replated yet. When I do I will post my results.
