Help me with a Fidelity Research FR64 part

I have the original part you're looking for, along with the whole original tonearm base, feel free to make an offer 

I will repeat that i have the original part, ask if you need it. Mine has been replaced with N-60 nut on one tonearm and with B-60 base on another.

The original N-60 is in this FR catalog from the 80's.
The name of that part is "N-60 Arm Stabilizer NUT" - this is written on the sticker on my original N-60 that i am using with FR-64fx tonearm. The original N-60 cost at least $250-300  

This part is an upgrade over the stock nut the OP is asking for, i have two (one from 64s, another from 64fx). The nut from 64fx is bigger and better.   

google translate:
"thingamajig - used to refer to or address a person or thing whose name one has forgotten, does not know, or does not wish to mention."

Normally a nut is something that looks like a nut, i mean the shape of that metal part designed for use with conventional wrench to tight it up. And the FR nut from the stock armbase is exactly a nut.

But the "Arm Stabilizer Nut" (aka N-60) is something much bigger and completely different shape.

Something that often called Tonearm Stabilizer does not looks like a nut at all, it’s huge and superheavy, here is one original stabilizer for Luxman tonearm designed by Micro Seiki. I would not call it a nut. The mass, material and size specially designed/chosen to control resonance. 

Fidelity-Reseach B-60 is not just an arm stabilizer, but a VTA on the fly, here is one.

Most of the machinists i have met are not interested to make just one small part, it is not interesting for them and they are busy with some serious orders. Unfortunately we're not their customes with one nut or one screw or anything like that (cheap parts).  

@lewm 

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. 

@lewm regarding the FR B-60 replica:
I have solved the little play between the inner and outer parts of my B-60 base, i was very disappointed by fact that local machinists can’t make any parts like that because they don’t want to bother at all with indivitual orders for such a small part, too cheap for them, they all want money.

After chatting with Nikola i realized his screws are the same size (just different material) and also must be fixed to get rid of the little play between the parts.

A friend has fixed my screw yesterday for FREE by hammering the upper part of the steel screw to squash it a bit to expand the diameter of the "nose" of that screw which goes to the slot in the inner part to prevent the lateral movement. Now everything is solved and i have no play horizontal between the parts, the screw sits in the slot tightly and everything is just fine.

I recommend this simple method to anyone with the same problem with B-60!

Sure, we're talking about $500 B-60 replica, i have never owned the original but it's too expensive anyway. I must admit the price for the original B-60 is absolutely crazy, for the price of that original part alone i bought the whole NOW Lustre GST-801 tonearm with similar base with VTA on the fly!

The screw in B-60 replica is made of steel (just like the whole replica), the diameter of the "nose" of the screw is 1.9 mm but the slot in the inner part of the base is slightly bigger, anyway the difference is tiny. 

However, the horizontal play between the arm and the base is big when the arm is attached everything is tightened. It is not acceplable for me, because i owned many tonearms and none of them have any play between the arm and the base. This problem  with B-60 and 64s is easy to fix as i described. 

Hammering the screw "nose" from the top (this part does not have a thread on it) is easy, but must be proceed carefully. We're talking about a very tiny difference, so it's not a big deal. No need for the new screw. As i said the problem fixed and my FR64s in B-60 replica sits perfectly (no play between the parts anymore). 

Did anyone ever find a reliable source for this part? I have an FR-64s with the large base (B60). However, I would like to mount the arm on my Thorens TD-124. To allow the arm to fit the 124, I believe I will need to buy a smaller base. I see a base on eBay for the FR-64fx...not sure if it is what I need. Any suggestions would be much appreciated. All the best, Mark

@mcmprov
You can buy it from me if you want the orignal nut from FR-64fx (which is much better than a nut from 64s). I have upgraded both 64s and 64fx with IKEDA VTA BASE and FR N60 stabilizer, so I don’t need those small original nuts anymore.

On its way to America, here is the image (genuine FR-64fx nut and washer).
