Help me with a Fidelity Research FR64 part
Parrotbee, I hope there is no blame at all attached to helping with this problem. Certainly none aimed at you or your machinist. Where are you located? Has any further progress been made?

This is "seat of the pants" thinking, but it seems to me that horizontal movement, if it is only evident when one applies considerable force in the horizontal plane, is not a deal killer.  If the tonearm is loose and flopping left to right or etc ...

Chakster, Until now, I did not know where the OP is located.  Obviously, his capacity to interact with a machinist in Oregon is limited by geography.  However, if a competent machinist knows the parameters (possibly M30X1.0), then the OP may be ab...

Parrotbee, Metric pitch is not measured in "threads per inch".  The inch is not a unit of distance in the metric system.  However, one inch = 25.4 mm.  The millimeter, etc, IS a unit of distance in metric. If you count 25 threads per inch, that wo...

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 I had to dial-in VTA and azimuth for every LP that I want to play, I would not be into vinyl at all. True, there are some anal individuals who feel compelled to do fiddly  things like that. I don’t. And I have wonderful sound from vinyl using ... 
Stylus not tracking and sounds terrible
 Most modern automobiles can go at least 10,000 miles between oil changes. Just so, it is no stretch of the imagination to think of a phonograph cartridge as a motor. It converts mechanical energy of the cantilever into an electrical signal. As in...

 Based on my prior experience with re-tooling for Fidelity research and technics products, I guessed earlier that it is metric. 25 threads per inch is just about one thread per millimeter, which is a standard for metric. The thread pitch is 1.0. O...

Ummm... Chak, I was just trying to be funny.  And I partially disagree with that definition of "thingamajig", having heard and used the term since the 1950s.  It refers to an object the correct term for which one either cannot recall at that momen... 
How many turntable’s have you owned?
Hold it, Dave. Turntables only. 
Need RCA loading plugs
Steve, Does your Einstein provide two pairs of phono inputs that are in parallel with each other, electrically?  That's the only case for which the simple solution offered here would work, simply.  Otherwise, you would have to piggy back one RCA p...

I am becoming unstable just reading this thread. Or maybe the correct term is "de-stabilized". But then, I am not a "stable genius".Having spent a great deal of time in Tokyo, owing to the fact that our dear son has chosen to make Japan his home, ... 
KD 500 w/ Grace 707 arm. Stylus type.
Guys, the tonearm the OP is going to use does not afford azimuth adjustment. That is what he is talking about. So he therefore believes he should select a stylus shape that is relatively tolerant of inaccurate azimuth adjustment. He could do two t...

That's a very kind offer from Chakster. 
Roadrunner reapearance
For the record, I thought Mantis was talking about driving a wall wart and controlling the motor with the wall wart on the output side of the PE-sourced gear.  This was based on my initial misunderstanding of the verbal diagram posted by Mantis. T...
