well alot of folks say
they're in, but few commit...
I did all the leg work for this for a bearing and platter to no avail, last year (part of a commercial design project as well). Part because I couldn't secure good manufacture (I relied on someone else), and part because of lack of commitment. I req'd the commitment to lock down a price and to secure supply. Only 2 folks or 30 that said "I'm in" provided deposits (which were refunded in full including Paypal premiums...). Neil Kaye and another that slips my mind if my memory is correct...
I still have the information. The platters can be provided in whatever dimensions one would want, within reason (43-46 mm thick seems a reasonable compromise X 305 mm, but 2.75 " or more are possible...), drilled with a small pilot hole, and a label recess area. Unpolished. The end user could have the finished bore machined locally, or if finished bearings were settled upon machined to that particular bearing as a group buy. My aim was to provide the end user with a finished bearing/platter in the $500-$600 range if my design, or a little more (10-20% depending on landed costs and shipping to the end users) if the high-end manufacturer's.
As I continued doing work on this after the GB "failed", one of the forum members suggested that he could access aerospace level machining. I provided finished drawings--he hasn't responded back to me in over 3 months...
If it seems that I am a little bitter, I'm not, just very pragmatic now. And I had even lined up a platter/bearing setup from a well known turntable manufacturer as well.
If any are interested (seriously), get serious and I'll restart my previous efforts. But some $$ commitment is required to fuel this along upfront. Also please note that I am personally known to more than a few moderators here at diyAudio.
Presently my "fixed bearing" has less than .0025" of play, uses a stainless steel shaft , grade 8 ball, Dupont Teflon thrust plate and Oilite oil impregnated bushing.
In fact I may be able to procure 30 tables (complete) and provide the recipe to fix the bearing to be done via the end user...

Bill Hi
Thanks for your efforts!
I think the price quoted is fair and reasonable,obviously Chris is doing us a favor here,for the love of the hobby and not for financial gains.Any word on the platter?
What the rest of the people here think,should we form a GB for the bearing only and worry about a suitable platter later?
Regards to all
George
