i thought of that, but only have the phil lockring and don't really want to cut those threads.

i called a good machinist, he told me what tool supplier to call. they told me they could have it made for a couple hundred dollars. anyone else have some hubs they want to chase the threads on??? lol.

i'll just use my triangular file some more then grease it and go for it i guess. there is one section of threading that is rolled over a bit that might be the culprit of all the friction.
