it is not decoupled as the rest of the bearing housing still touches the black bowl. its more to seal rather than couple or damp imo.
this dreaded black washer really is the weak link in the chain.
This is in keeping with the Good News being made known within this Thread.
There will be opportunities to share in the experience where the New Materials are incorporated as the Bushes, and if all goes to the plan, the excessive Sideways Spindle Movement will no longer be raising a concern.
I am in Line for Two Sets, so there is a GB of Three already in place.
In the earlier conversation with the Engineer, they were of the View the Thrust Pad if seen not to be showing any signs of a Wear is OK to be continued to be used as a Thrust Pad.
It will need to be treated with a Thread Seal that is compatible with a Plastic Material.
Through my years of learning about producing a Mechanical Interface for a Bearing Housing on a Chassis.
I have settled with the idea that a flexion is best minimised and if possible, the interface of the Two Materials is best designed so that it is not able to have any flexion detected.
Hence a Chassis with a Suspended Bearing Housing is best given the maximum support for the Chassis so that the Bearing Housing has been coupled with a rigid interface.
In the case of the TTS 8000 the Factory Interface does not appear to offer a rigid interface, there does appear to methods for the fastening of the parts used in the overall assembly that can yield.
Most Important, once the excessive movements within the Spindle > Bush Interface is resolved, the TTS 8000 will be offering a change to the performance.
The users assessment of the TT with Torlon Bushes now in use suggests there is a decrease in the Noise being produced.
If the changes are seen to be a improvement across the wider group of users, there will be a time to consider if any other methods to create a change to the Bearing Housing Mechanical Interfaces are deemed as necessary.
In the SP10 Thread within this forum, the most recent contributor who is supplying information that is receiving a following has identified a flexion in the SP 10 Bearing Assembly that is measurable and is stated as being 0.1mm.
Measures are being investigated to reduce the measured flexion.
Even though the TTS 8000 and SP10 MK II have a Bowl that is a Interface for the Bearing Housing.
I have not had my hands on a SP10 Bearing Assemblies Parts.
The images I have seen of the SP10 Mk II Bowl, show it as being a Lower Profile and what seems to be a Substantially Thicker Material, when compared to the TTS 8000.
This design for the materials would suggest the entirety of the assembly has the potential to be of a increased rigidity.

If you take two sets, should that not be four sets already?.....😉 but seriously, thanks John for starting this thread.
If the additional inquiry that was made from an earlier interest prior to this thread commencing is added, then the Count quickly makes 5.
From the discussion I have had and knowing the Costs of Torlon, I am sure the asking price for the GB of 10 will be very appealing.
The Thread has been very well received and is in its early days, I am sure a few will come on board and show even better ideas outside of the Bearing Bushes that are worthy to be considered.
I will off course be showing my project as it comes to fruition.
The works on this depends on the Engineers Schedule and I am not applying any Pressure, as we are involved in another TT Project as well, where I have supplied some Donor Parts and encouraged the project to be considered.
In my Drawings for the TTS 8000 Bearing Assembly, I have attempted in the Design to keep all the OEM parts as a retro fit, and this is achieved.

having spoken to 'our engineer friend' today i also have a plan to reduce flex in the bowl which is something a long with an uprated thrust pad i can do myself. id like to explore lignum vitae as a start.

Hi Jamie
referring to the 'uprated thrust pad'.
Is this to be a version of the existing design and be able to be used in the Pressed Bowl ?
I only ask as there may be contributors to this Thread that might express an interest in acquiring one.

Being out for a few days, I discovered that a lot is going on here.
Please put me on the list for the GB with 2 pairs (4 pcs.) of bushings for both of my TTS-8000.

Audiomusica was the inquiry I referred to.
With the request now made for Two Sets that now brings us to a GB of Six Sets.
If we can make a GB of 7, I will incur the cost of the last three, this will get the Order Started of prematurely.
I'm sure a further interest will be made known and I will be able to help with the inquiry.

If it is just one pair that's missing, put it on my bill too. I'm sure I'll find a guy in a german forum I can pass it through.
This really seem to get going - 
- I am definitely in - and of course good question about TORLON 😀.
- I am definitely in - and of course good question about TORLON 😀.
With the knowledge now acquired there is a requirement to use a Lubrication with the Torlon.
It would be further beneficial to look into a Method to Produce a Oil Tight Sump that will retain the Lubrication.
As previously said a Thread Seal that is not detrimental for a Plastic Material can be considered to be used on the OEM Thrust Pad / Sump Plug is this is wanted to be continued with as the Thrust Pad.
The Bearing Housing will be removed to enable the removal of the OEM Bushes and Insert the Replacement Torlon Parts.
In the mean time, while the Bushes are to be produced.
It would be very reassuring if a opportunity develops, be ne able to have discovered a method that is simplistic and only requires the replacement of the Square Walled O Ring to use as an alternative Part and become a effective Oil Tight Side Wall to the Sump.
This will allow for various Volumes of lubricant to be worked with.
I am not sure if there is a Minimum Volume, or where a cut off point is for a fill of a Lubrication.
As a layman's guide to Torlon, it is a Material that is one of the most dependable Thermoplastics and finds itself selected for Numerous Purposes as it functions to very high performance level throughout a range of Temperatures.
It is produced in various grades as there are various additives to the Polymer.
PTFE and Graphite are commonly used to produce a Low Coefficient of Friction.
It is a Material Identified to be used within a Bearing Assembly, and Torlon can be selected to be used as a Lubritared or Non Lubricated Bearing Part.
Fortunately as a Material it is relatively easy to source in a Quantity that suits small run projects.
It quite popular with Hobbyist Machinists for this reason.

Does this Wonderful Silence mean the Contributors are Designing a New Sump Side Wall Part ?
There is always a simple solution, the Method will reveal itself.
As always it the 'When', but when is does manifest it will be very welcome.
As some of the other Methods that can be incorporated outside of the Pressed Bowl can be achieved with a relative ease.

Yes Jamie I would query that -
Sump=repository at the bottom of a car (automobile ) engine to hold the oil--or-- sewage drainage on land not connected to the local council,s main system --- or "biblical "-- water storage etc etc.
As the bottom of the bearing is directly part of the bearing containing oil to lubricate then it would correctly be called the Bearing Sump . Making a completely separated sump presents its own problems in engineering due to pressure /oil containment/cost etc.
