Yes since it will not be a Spring Loaded design, Mass Loading will equal Mass Dampening. Make sure your rack is just as robust to handle this beast!

if you haven't already you should check out the forums on http://www.diyaudio.com/. There's one whole forum dedicated to Analog projects, and many DIY tables. |
Hi Pedrillo, Have you read the original correspondance between the primary architects of a DIY effort to clone Thomas Scheu's high mass Premier tunrtable. Their efforts later became the high-end turntable companies Teres Audio, Galibier Design, and Red Point Audio. The original builders have kindly saved all their discussions for anyone interested in DIY turntable design and made them available on the Teres Audio website. The entire archive of all the their analysis and research into: Bearing and Platter Base and Subchassis Motor and Controller Drive Belts Bearing Oil Arms and Cartridges Cartridge Alignment Record Clamping There is a detailed discussion and explanation of absolutely everything needed to design a reference level high mass table. More importantly, if you read the entire discussion in order(it's is humungous), you see all the wrong assumptions they make and later figure out. Also, all the obvious assumptions that later turnout to be less than optimal. It can save you months or years of effort and an untold amount of money on wrong turns. Also, you can save yourself a lot of effort by buying precision bearings, platters, and motors specifically for high mass tables directly from Teres or Scheu Analogue. Not cheap, but what you get is of the highest quality. There are also several long discussions/projects on every part of a turntable in the archives of DIY Audio's Analogue forum(examples 1, 2, 3, 4, 5, 6). Anyway, I hope this provides a good start for your project. |
