If you want precision and balance, then Al is going to be much better than wood, and pretty much any decent shop can make it for you to tolerances that begin where the wood cutters stop.
I am not sure if that is required or not, and the wood might make for a "fun" platter.
In any event, mass is just one way to manage wow and flutter, you really need a feedback loop. Even my sub $ 200 turntable from the 80s came with some kind of light source on the side that was part of a frequency lock loop arrangement.
BTW - thin layered veneers of quality wood bonded and vacuum bagged together are pretty impressive.
I think it is going to be touch to find a commercial shop to take on the project for less than the product you linked to. If your goal is to achieve it for perhaps 1/2 of that, then it might be useful to consider posting on craigslist. |
