Nottingham Space Deck and Space Arm question?

My advice is to get in contact directly with Nottingham Analogue. I had some serious issues with my Spacedeck and Penny Jones from NA gave me all the support needed - including shipping me some parts. 
Amazing people at Nottingham Analogue, taking care of customers. 

OK, thanks for the kind responses.....

I am just a bit confused at this point......everything I have researched tells me that this lift was made by Rega, and countless comparisons from images along with the maintenance info on VinylEngine confirms this as accurate.  When I contacted NAS, Penny Jones sent me a reply that contradicts all this:

"Hello Andreas
Thank you for your enquiry.
The lift/lower device will need replacing.
You must not use any grease / oil and there is no way to 'tighten' up the movement.
Sometimes heat / cold can effect these devices.
Please contact our distributor for the US, they should be able to help you.
Contact: Audio Encounter Solutions (aka Hollywood Sound, Florida).

I hope the above is of help to you.
With kind regards
Penny
Nottingham Analogue Studio"

So, where does this leave me?  Rega even spells out that there IS a grease:  "Re-grease using only Rega supplied lift-lower grease..."  More digging reveals that this is actually pure silicon oil 300K cst.  Maybe my old, original lift would indeed have been salvageable had I known this.....

After disassembling the new one, I found.....you guessed it, that sticky silicon stuff in the piston/cylinder.  While Rega directs one to "completely fill the groove in the piston," there was only a very, very tiny amount of it in the groove.  I carefully removed what was in the groove and applied it to the piston before re-assembling and the lift now drops somewhat slower, so that should be an indicator that there was too little applied from the manufacturer to begin with?

I am still waiting on the aforementioned return call from Hollywood Sounds, although they told me originally that they did not believe these could be fixed and that a new one was the only way to remedy the situation.  I would have been plenty happy to spring for a new one provided it worked correctly, but getting one that drops faster than it should kind of sours me on this "deal." I'm in hopes that a small amount of the  300K cst will be all that is required to get it to drop in the fashion one might expect, slowly and accurately.  Will keep everyone posted as I see this has been an issue for more than just myself.

As a 294 owner I'm Interested in seeing how this gets resolved. Thanks for keeping us posted. 

Thanks, Joegator81......so am I and I will report back as to what I find.  

Update, sorry it's taken so long but I just yesterday received what I thought would be the fix......not so, not even close!  The tech at Hollywood Sound sent me some 3,000cst silicone oil, and I expect he thought it was 300,000cst.  In any case, I did not look carefully at the vial he sent, thinking he had understood it needed 300,000cst and just coated the piston and groove, turned it about in the cylinder to coat each surface and re-installed only to see it drop like a rock!  THEN I looked at the vial and noticed it was 3,000cst!  Will send the vial back to him and start sourcing some of the 300,000cst myself.  Keep you posted as to the eventual outcome......
