Thoughts On Turntable Clamps And Weights

Thanks for reporting back. I think you correctly assessed the info… light weight clamp. I know my TT would not do well with a heavy… perhaps even a light weight.

@pindac

I think you mean ’thrust bushing’. Only a very few commercial TT offer an air cushion in all three dimensions, as does a thrust bushing, and they are all well north of 100K.

Their 35mm thrust bushing can support up to 60kg, so safely 45, which is what I use. Supports 60kg and resets a radial force a hundred times more than we need. The perfect solution in one piece.

I have dealt with New Way for years, and they are very good to deal with. If I were doing it again, I would get them to make the spindle as well - expensive, but guaranteed to work to the highest specification.

You can afford it when you are saving 100k !

@terry9 Thank You again, the penny has completely dripped and I am a duck to water on this one.

I can not see any reason to avoid making this info known, to both of the individuals I spend time with who produce TA's and work on TT's, I see this info as something they may seriously consider adopting. There selected Bearings used on their TA's are extremely 'state of the art' and 'Rocking Horse Poo' to find a small in qty supply source. 

Such an idea as yours must surely stimulate their thoughts, as it has my own.  

Terry, no, I am not talking or thinking about a loss of high frequencies in the audible range. Suffice to say I prefer the L07D without its peripheral ring. Any adjective I choose is bound to give someone somewhere the wrong impression. Language fails us.

@lewm  Understood. Thanks.

@pindac  The factory will sell to you directly, at least, they sell directly to me. Also, they give free advice. I find it easiest to buy everything from them: air fittings, shafting, end blocks to support shafting, etc. I also use their 20mm air bushing for my LT tonearm - there's a picture of it in the DIY audio thread on air bearing LT's.

IF you go air on your TT, it's natural to go with air for the TA. You'll need a good compressor - I use a stainless steel commercial unit from Werther (Italy), model CWF100 TC INOX. Only disadvantage is that it's noisy and has to go in it's own shed, outside the house. If noise is a consideration, consider the Val-air series, also by Werther.

Good luck!
