There is not a Link as such, the design is Bespoke Made.
If you do look across the years of SME Designs since their 30xx Models were released.
The insertable removeable Headshells used on the 30xx range, (the design mimicked by many Brands), as a design, are inserted into an additional connected fastened into the Wand. Once seated the removable part is tightened in place by a Threaded Ferrule. I won't say too much on this as a design for a role where two parts are connected to the end of the Wand, especially where a rigid coupling being in place is the ideal.
This earlier design from SME was not transferred over to the Companies M2 xx Design. This design used for M2 xx, is robust and has a mounting method that has the Wand as the internal, with the Headshell clamping down onto the sleeve that is concealing the Wand and serving as a means to increase the OD over a proportion of the length of the Wand. This still remains a Two Part Connection for the Headshell, but has the design incorporated to enable a rigid clamping of the Headshell to the Sleeve. I am giving the benefit of any doubt to the Sleeve and suggest it is a very tightly coupled part, and an adequately tight clamp fastening will finish the connection nicely.
The later of the SME Removable Headshell Designs was with a increased substance and designed to directly couple onto a Tapered Wand.
I don't see the Headshell Connection used for the SME 309, IV and V having any potential to not be rigidly coupled, as long as the Clamp Fastening is adequately tightened.
For the two later designs of removable Headshell, my gut has always been toward using a Torque Setting at the time of securing the Headshell, as this would give a consistency to the mechanical interface.
In relation to my earlier post. I was given demo's from the same TA. Encountering it evolve from a version of the SME Bayonet Headshell, to a Bespoke Interference Fit Design. I made the impression this made known earlier and it was very impressive.
An additional experience I had at a later date, was when the same TA, was using PC Triple C Wand Wire. This Wire Type is the same Wire used by SAEC in their TORT TA.
I am a advocate of a particular wire type, which is PC Triple C.
It has been experienced in use in my own system and others over time.
I was always looking for a diameter to suit Wand Wire but finding it with a sheath was not easy.
I learnt the PC Triple C Wire is in use in a SAEC TA, and this was very encouraging.
In the end after many investigations a suitable sheathed wire was discovered, with an ideal OD.
I was demo'd this Wire, used on the very familiar to myself TA and System. The experience proved to be something very special. SAEC has got it correct I am sure, and my encouraging a friend to investigate and produce a version was the best call I have been instrumental in encouraging to be realised for a very long time.
