bamboo platter for a Turntable?

jorsan · 28th December 2011, 08:40 PM

Searching in the web found a very nice and beautifull finished 12" round 2" thick cutting board made out of bamboo that should be used as a platter for a DIY TT. Would like to here from experienced people what they think about this option ... maybe could be combined with other materials (aluminum, steel or acrylic) to make it more suitable for that use?. thanks and happy holidays!

Interesting idea. Bamboo plywood is rather stiff and dense. It works very well for speaker cabinets. Waiting to hear what some of the TT guys think.

I would be concerned that you could machine and balance it well enough. Not knowing your proposed drive method, understanding the mass so your servo Q would be a bit of trial and error. It would be unique.

Thanks for the responses. I think there is no need to machine. is already cut, perfectly rounded and all that is need it is to insert the bearing if no other material will be used. Do a search under " miu bamboo round cutting board " there is one of 12" and another of 15", you will see what Im talking about.

Looks great. It'll work at least as well as the acrylic platters you see. The glue between the layers and the pith between the hard fibers will absorb vibratory energy. You just have to find the center perfectly.

Thanks. Yes, I know that find the center is critical and will contact a friend who works with steel sluminum and that stuff to help me with that. About e bearing and the top spindle, any recomendations? The idea is to keep the expenses in a contolled budget.

another one, do you consider a plus to use another material in the platter? for example glue to the bottom an addicional platter made out of acrylic or aluminum or steel?

Just thought I'd compare price/availability between US & UK:

US (Amazon) $34.62
UK (sjh-row.com) £102.86 (158.530 USD!)

Looks like another bargain for UK shoppers

Maybe they swim with them across the English Channel (La Manche)..

US (Amazon) $34,62 and ..... free shipping ! looks like they are not selling much of those and want to get rid of the stock that they have but anyway, where can you find a piece of this quality for this price? I bought one and the photos dont do justice.
I also bought a 24" x 18" X 2" rectangular cutting board same material and finish for my garrard 401 new plinth, Im sure will do the job perfectly.

I was thinking about use 2 of them with a 1/4" of aluminum disc in the middle where the drive belt can run, will look very nice but dont know if this would be too much ... what do you think?
