Help me with a Fidelity Research FR64 part


I got a mint FR64 tonearm at a great price. Sadly there was a catch it did not have the nut that fastens the arm at the base. It is a really fine thread (25 threads per inch) in fact my machinist doesn't have tooling for this.

so I want to know if anyone out there knows where I can get the said nut, or if they have one they can sell me - thanks

As I mentioned at the top of the thread (I think), I DO know a machinist who most likely would make this single nut for the OP, if he is given the correct specifications to work from. That is Colby Lamb in Oregon, USA. I can provide contact info, if desired.


What if the OP is not in USA like myself ?

 Colby made me a new threaded retaining ring for my SP10 MK3 platter; without that part it is impossible to fix the platter in place.


 I think the price one can pay for an important part of the $8k turntable is another story.

I couldn't find any machinist who can make even one small screw for my B-60, they are all laughing at me, maybe if i will order 100 screws they can deal with it. With such a small nut it can be the same. They don't want to bother at all, at least in my town. Not every one is ready to work with such a small individual orders for cheap custom parts. 

The first Japanese engineers are educated in Germany so, as
Lew assumed, use(d) metric system. The stubborn and arrogant English and Americans thought that the rest of the world will follow them with their inscrutable measuring system (grin).        
One can’t help wondering if those German engineers were the same ones Russia sent back after the war.
Shipping for that one nut/bolt/stabilizer/whatever is around $100 ($89 for Asia)? That is some precious stuff.
