I've got this silly idea for a design using bicycle spokes. I can't measure this
thread and I don't know metric threads very well at all. I do have a real cheapo
shadowgraph style optical comparator, and was able to get what I believe is a
usable picture. The scale shown is millimeters, and it appears there are either
20 or 21 threads per 10mm, don't know which to count as #1. The spoke threads
mic at .078" which is real close to 2mm. Not that I have a die this size, but
can anyone ID this thread and explain how to do it? See the image:
