I have gone down a similar route to Pete and agree with the principles.  What sort of noise the new Peco  TT Controller / Motor makes is unknown, but largely irrelevant as the price is on a par with kits available already and it operates by pushing buttons.  It doesn't have indexing, as was originally intended.  I would rather have the better speed control of a controller, DC or DCC and it works very well for me.

That said, I haven't experienced any noise with the wheels, either the original Peco or replacement Alloy ones made to the same designs but tighter spec, to eliminate the slight, unsightly wobble of the plastic ones.  Timing videos of full size turntables revealed times of 1.20 - 1.40 per 180 rotation and at speeds well above that I can still hear nothing from the wheels.  That said, should the problem occur on a model, Pete's solutions may cure the noise, as would painting a rubber solution on the rims of the wheels.

The depth of rubber is consistent using traction tyres, whereas a rubber solution would not be so even.
Bear in mind that l was chasing noise sources as an engineering exercise, not working to the principle of near enough is good enough, nor RAF's ILAR or ISAR standards.😉

The Mech is noisy because its of thin material with loose relationships between mating gears AND gears and their axles or bearings.

Add mass to the mechanism itself (sides etc) to reduce amplification
Mount the mech using only bathroom silicone and not huts and screws etc (start with both then remove the screws is OK as long as a good layer of silicone remains between mech and turntable)
Add mass to the turntable base (randomly placed and uneven in placement) to reduce amplification
Add a thick high viscosity oil (chainsaw chain oil is a good example)

Or... just use a higher quality mech such as a gear-head motor

Morning, Ahjay
Done all that.
It's silent until notch 12.
Mind, l may use the base as an amplifier when l fit a sound decoder.😉 ðŸ˜
The 360 degree slip-rings work well with no loco sound interruption anywhere in a full rotation.
Anyway, it amused me for a few hours, and that is what the hobby is about, surely?

I have made holes between the bars on one of the grates on the Well floor and opened them up, with the speaker behind.  I have yet to fix the speaker and sound box behind it, but the sound comes through very nicely already.

The grate cuts through easily enough, just requiring a little patience and ligh-ish strokes with a very sharp blade.  The view from the top is an improvement too, I wish I had done it earlier and built them all from scratch.  Hey ho, now I know...

The indexing arrangement of motorising a Peco turntable is not difficult but requires consideration. In this forum there is an article on motorising a Peco turntable for use with DCC control. Any member who requires information please contact me off forum as I have written several articles in various magazines outlining how this can be done . Whilst I have not used the Peco motorising kit for using with their turntable kits , I have read and viewed the documentation of how to achieve a successful indexing arrangement. I motorised a Peco N gauge turntable successfully and 98% of the time aligns perfectly . I used a stepper motor and an a Hall sensor to align the exits again contact me off the forum if you want further information. A word of caution the Peco N gauge turntable kit being plastic has a lot of inbuilt faults due the moulding techniques and the limitations of plastic mouldings. I am not entirely sure if these are due to the age of the moulds used by Peco  or by the original design however it is possible to motorise one , I can only speak from my experience in N Gauge , I can see no reason why the indexing arrangement can not be used with the Peco motor, however to just rely on eyeballing the alignment in N guage especally is a not entity. As I have stated if you want further information contact me and I am happy to assist .

I have just taken delivery of this from ADM turntables..

( I am not even smart enough to rotate this though 90 degrees in this post!) because it works beautifully looks amazing and I don't have the technical skills to match this.  I am surprised DCC Concepts don't team up with ADM to mass produce this and maybe halve the cost but maybe most of the members here have the skills to do their own indexing malarkey

Superb Andrew.  I have an idea of where I would like to install one at some point and I am convinced that the ADM unit is the best there is but it requires a lot of space below it and that is where I might struggle.  I would have to get creative I guess.  Do you mind me asking how much it cost?  I checked up on them at a show a couple of years ago and left the stall a little shocked.

I didn't realise it came finished and weathered and it looks like they have done a nice job on it as well.  I have just sold a motorcycle and put some funds in the kitty so perhaps now is a good time?

so I can tell you it wasn't cheap (north of £500!) as I went for the Zen edition (it's one with everything😂), but not sure Alistair would want me to share publicly so ping me direct or message me ( I am easy to find except on Facebook). Clearance needed below is 125mm. so I did have to move the odd support about and I did plan for a turntable originally.  I also swapped out the cat 5 cable to the controller for a 4 metre cable to where I control everything - my pc workstation.  Click image for larger version - Name: 20200522_150438.jpg, Views: 20, Size: 242.41 KB

We have been working towards getting the ADM turntable, to work using push buttons digitally from a Mimic control Panel.
This can be done in a couple of ways.
One is to use our AEU connected to push buttons one for the head end and one for the tail, this in turn sends the digital address set into the ADM system, and moves the Table Bridge to the correct route.
This works extremely well if you dont want to use the supplied separate controller and like just buttons on the roads.
This also works with any Turntable that has a digital road address option.
The second is a bit more involved, and again is for a Mimic control panel, but this one has led indication for the road set as in green, and all other roads show red.
So far i have only got this one working if you have a NCE Pro system, as it requires a lot of macro Commands for the led indication, these are stored in the system itself.
The push button on the panel sends a simple macro command via a NCE mini-panel, one part sends the command to the Turntable and the other parts to the system for the leds,

This is the simple version, just using the Push buttons, it can be used on any system via Alpha Power and Box.

The second option using NCE and Alpha Mimic.
Take Care Guys.

@platelayer I use RailMaster on a 23" touchscreen all in one PC.  I am always looking at the market as Hornby don't seem to have invested in RailMaster at all recently and I can only imagine the fun and games getting something advanced like this turntable to integrate fully into that.  They have outsourced it and it does not run securely on Windows 10 and the user experience is very dated.
