Aside from it needing an oil change anyway, I think the clue to the knocking is right here in your original post:

Anyway, moved it around a little for some work.

My guess is that it just needs to be set up again, level, everything aligned etc, just as you would if you were taking it out of the box for the first time.
I'm certain there is nothing wrong with that bearing - that's just old oil. These Notts turntables are built like WWII military equipment.
Oh, and I was charged not a penny when they sorted the wiring on my arm. They're better even than Naim service was back in the peak years.
 
Hiya all.

Sorry for the low quality images. I should have used the ''good'' camera.

The oil is so old I would be embarrased to say. I will order some more pronto.

The nosie is definately the motor - when belt is removed it is completely silent.

Jonathan - yup, this Mentor used the same bearing as the Dais and the Anna-Log.. so I would have been dissapointed if it had been knackered.

I will try the tapping thing and see what happens.

I will call Notts today for a chat about it too.

Thanks all :)

PS
I reccomend listening to the below band on Spotify, then buying the vinyl if you like the music. It's an ace slab of vinyl, sounds great.

Spoken to them, and it just needs an oil change.

I had a quick google of ''tunrtable oil'' and have opened a real lions-den.

There are people using a specialist motor oil, there are others on Ebay decanting such oil into little bottles and selling them for large sums.

There are claims made about this oil (red) that oil (black)...

I know it's audiophilia, but am sad to see it effecting something like this.

I don't suffer from foo-ey-itus, and my heart tells me that some kind of hi-tec oil that is good enough for tolerances inside a high performance engine will be good enough for my platter.

What are your thoughts?

*edit* I know the safe thing to do is use Nott Analogue oil, but I'm sure they don't manufacture oil ..

I may well just buy the Notts stuff, but its an interesting topic I've not seen discussed on PFM.

Well a bit interesting.

A little maybe.

If you decide to use a motor oil make sure it's a GL4 type, not GL5 as the latter is not safe for use on bronze or brass parts. I've used and 80-90w GL4 oil on various types of deck for decades, though I used the Nottongham Analogue oil when I had a Spacedeck as it came with it and it seemed rude not to. I'm using Loricraft's oil now, as that came with my 301 when it came back from the service. Both seem thinner than my old bottle of GL4 motor oil. I can't remember what I've got in the 124, probably the Loricraft stuff with a dab of grease across the gasket.

Tony.
 
Just buy the Notts oil. There is enough to do several changes so it will last a very long time.
As far as other oils goes - isn't there a better way of using life's precious hours? Tom Fletcher knew what he was doing, so trust his judgement and enjoy the summer instead.
 
100 % with rasher here for the price of a few packs of fags a crate of stella or nice red wine whats the point in messing about just get the Notts oil. It may be just standard bearing oil who knows but at least you know its the correct spec for the TT. Your motor will most likely quiet down after a run of a few days.
 
Hi

Yup, am going to do exactly that.

I do think that it is expensive for what it is, but lets face it - this is audio, and that's the way it is.

At least I'll know I have the right oil, which is worth the extra.


I know one day I'll discover it's Castrol GTX or something and laugh :D, but there we go.

NB
Just want to say how much I love my NAS deck. I have zero desire to change it, absolutely none, zip, nada, not at all.
It just purposefully and completely does it's job, like a door opens and closes, sure, there are Star Trek doors that go whoooshhhh and make a cool noise, but I am perfectly happy with the normal opening and closing type :)
 
I loved my old mentor too and wouldn't have changed it save for a really good deal on the dais at just the right time. The dais does get more out from the grooves giving a more texture to instruments etc but the major plus is being easily able to run two arms. Id still be very very happy and proud with my old Mentor though. NAS decks just make music no faf minimal set up required pretty happy about support provided its sturdy and bullet proof build quality. Changing the oil once a year and the belt every 10 or so is all it needs. Tom Fletcher = Genius sadly missed.
 
I love mine too (AceSpace)
There is something honest and wholesome about them, sort of modern old-skool.

I've got a carpenter making me some oak windows at the moment and I can go visit him at his workshop and smell the freshly cut oak. NAS to me is still like that, among a sea of white UPVC. I wouldn't change mine.
 
Having missed out on a (rather expensive) Raven A C recently, I'm re-evaluating the Dais, preferring its accessible British manufacturing base and value for money aspect.

However, There are three things I can't quite get my head around.

Its somewhat top-heavy and rudimentary (agricultural?) appearance, being mostly platter and little plinth,

its enormous mass of steel in close proximity to high quality moving coil magnets (Tom F only played with moving magnets, I gather), and

that you have to start (and presumably stop) the platter by hand; if you're right-handed, as I am, this tempts fate with the stylus, I feel.

Any owners out there care to pour scorn on the above caveats, please go ahead; I'm listening.
 
coool will try - but there is no scorn here , just user experience. . and I have a mentor (above), but its pretty similar.

Yes, all the weight is in the platter. It weighs a ton. the silicone band though takes the vibration from the motor to this platter, and vibration has to go through something massive and heavy before it hits the needle which you dont want it to do, or as little as possible.

Above the steel there is a good inch of I think it is carbon fibre. Its a good inch of something like that on mine, its not metal for the top inch anyway.

you do have to give it a really hard shove. I'm right handed, but you can use your left hand to shove it. I do. I have 2 arms :D

Main criticism would be the sound is slightly ''fat and heavy''. I like that myself, its like beef wellington. Look elsewhere for the ballet dancer though.
 
It's graphite. The top inch is a graphite platter.
I'm right handed but have never used my right hand to spin it up. I seem to have one hand going for the arm to cue up and the left hand somehow is automatically giving the platter a spin. It's second nature.

Heavy sounding? Is it? It has solidity where it's needed, but mine has a lightness of touch that leaves me spellbound. It's an all round good package to me. I have the heavy kit and Wave Mechanic power supply, and it's this power supply that can make the quiet stuff go even quieter - to the point where sometimes I think it's only me that's ever heard these brushed notes and resonances. It's magical in a way.
 
I spin my Notts deck with my right hand but in a sort of googly action - on the left side of the platter. Heh I just got cricket and Notts deck into a sentence. I am ace.
