I understood just fine. Scratchy said do it on a lathe. I'm a huge fan of tap an dies but good luck trying to do that with a split die in wood never mind the non split die that was shown.Let me clarify my statement, I think the picture does show what appears to be a typical 60 degree V thread, but it is not a common size. Standard sizes are generally either 1/2-13 or 1/2-20. A 1/2-10 would likely be listed as a Special thread in a Machinists handbook. There are at least taps available for that size but not typically found in general hardware or automotive supply houses. Since there are taps, I would assume dies are available as well, but like someone above said, better to single point that in wood.
