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

Dear dover, Lew is my English teacher so I agree with him and
consequently disagree with you, ''NUT'' and ''STABILIZER'' are
different ''animals'' despite the right picture on your reference. 
The name by your picture should be ''NUT'' and not STABILIZER.
The later are much bigger and heavier. One can see the difference
by comparing the original FR-64 NUT with B-60 stabilizer. 


Dear chakster, I also bought replica B-60 so don't need the original
shaft (or ''base'') with mention NUT. However this (whole) part is
also offered for sell on different sites. You can't sell this part
without the nut or get the same price as with the nut included. 
I am surprised that you need such advise (grin). 

Dear dover, this is the most strange argument against my proposition
I have ever heard; that primary language in Japan is not English.
If you read whatever translation from Japanese in English you can
hardly understand what they mean (grin). However our discussion is
in English and in this language one discriminate between NUT and
STABILIZER. The function of an name is to refer to some object in
the so called ''reality''. In this reality one can see the difference 
between an nut and an stabilizer. If ''form follows function''  then
the function of both objects is different: nut is to fasten something to
something else , stabilizer to , uh, stabilize with weight the involved
construction. 
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).        
Dear geofkait, Your question ''if those German ingineers were
the same which Russian send back after the war?'' is interesting.
Russian obsession with secrecy is the reason that much is
unknown about German-Russian military cooperation. To avoid
limitations prescribed by ''Versailles treaty'' Germans organized
their military development in Russia. What both parties learned
from each other is not known but in 1950 about 170 German
''scientist'' were sent back to Germany. According to Korolev
(Russian rocket scientist and  leader of ditto program) they were
useless to Russia. This means that Russians were further in
technological development in rocket- as well nuclear science.
Rockets are already used in the war as the so called ''Stalin 
organs'' .  Japan was in its development first dependant from
Holland which was the only state allowed in Japan. Their
expression for ''science'' is translation of ''Dutch''. But Holland
was to small for so many Japanese students. So they were sent
to Germany to study mechanical engineering. Before or around
the first WW.

Dear chakster, ''the nose'' of the screw should not be hammered
for obvious reason of damaging the thread. I used vice instead
assuming that the screw is not made from steel but some other,
softer material. For this reason one should not apply to much
force but proceed gradual.  
The difference between ''genuine'' and replica B-60 is $2000.
The genuine cost $2500 the replica $500. However this difference
is ''academic'' because the replica is not available anymore.
The only problem by the replica is the screw which connect the
outer and inner side of the VTA adjuster. As chakster and I discovered this can be easily corrected. One need to mark the
center position of the screw and then squeeze the opposite sides
with the vice in order to ''widen'' the ''nose'' of the screw, The screw
is easily reachable by unscrewing of the, uh, ''stabilizer''. Then 
check for the horizontal movement and try again if not satisfy. 
But one need to proceed careful because the most own just one
of those screws. So don't ''screw the screw''.
