    Nowadays if you can't get what you need from B&Q or Wickes try ebay

    That sounds excellent. I went with these guys https://vinylnirvana.com/product-category/thorens-part they claim to do pretty much the same as yours from Denmark. I don't have the luxury of another TD160 to compare but I have heard several TD160's so have a rough idea of what to expect. I'm now looking into the effects of the mass of the rubber mats as it appears a specific weight may improve platter speed stability. My deck now runs at 33.5rpm initially it ran at 33.8 rpm (1.48% faster), now it's 0.6% faster. I think I can get this down further still with suspension tweaks. More later.....

    Speed control on these old decks is where i think the greatest improvements are to be had, relying on mains frequency to control your motor speed as we all know isn't the best plan, ProJect used to make a turntable PSU that could not only run a 230V ac motor but also output a variable frequency range so that fine tuning became possible as well as 33 to 45 electronic speed change, for some reason they aren't available anymore, a company called Heed make something similar but i don't think it has a display to show output frequency and i'm not sure if any fine adjustment of the generated frequency is possible

    Wickes is best for me. It's not only cheaper but the quality is better, others seem to be quite shoddy. I'm also experimenting with Bamboo.

    I've a power regenerator at home, it would be interesting to see if this helps out, I'm quite sceptical and don't think it'll make a jot of difference. Still, that's an experiment for tonight.

    The flywheel effect from the weight of the Thorens platter and its peripheral mass are sufficient to keep speed variation low, at six one thousandths of one percent.
    Repeat after me 'I must not look on ebay! I must not look on ebay! I must not look on ebay! I must not look on ebay!

    Wonderful turntable and project. Hope all goes well for you and the Thorens.

    Geoff, that's a really interesting statement. Can you show me the maths please.

    but it doesn't help with a motor that's running a little fast or slow and this is where the ability to adjust the frequency is a great help

    Pt 6 - Productive day.

    Hello friends. Another day another update. Today we received notification that the oil we commissioned for spindle and bearing lubrication has been formulated. I will also be offering this for sale from my Wakefield Turntables facebook page. And no it's not 3-in-1 oil badged up as something special! I've been researching baseboard materials and have found something that I'll be experimenting with over the next week or two and then I'll do further experiments with bitumen damping. I've ordered a bench polisher and enough polishing compounds to stock a small store. I'm hoping to have a nice polished platter and should be able to lightly polish the inner platter rim to remove old rubber belt residue and even the bearing spindle itself. I'll also be offering a platter polishing service if anyone is interested. More to follow....

    A bench polisher will certainly be quicker than Autosol

    I have used a number of oils on my VPI bearing Andy and found fully synthetic oil pretty good.
