Technics SP-10 Tonearm Pod instead of Plinth/Base

Trawling through the Audiogon forums for information on a suitable Plinth for a Technics SP-10, I came across a post by Raul.
Instead of putting the SP-10 in a plinth, he just put the TT on three feet and then had constructed a separate base that only housed the tonearm. (I haven't seen a pic of this BTW)
Following on from Raul's 'Thinking outside the square' approach, I thought I might be able to buy, or have made, a stand-alone 'pod' or rectangular tonearm plinth that could sit along side the SP-10. Has anyone seen something like this that I could buy 'off-the-shelf'?
The advantage of this is that the tonearm is decoupled from the TT and therefore distanced from any vibrations generated by the TT.
A down side is getting the right geometry for the tonearm in relation to the distance from the spindle; and then keeping the pod in the right spot.
If this is all too hard, I might still go with a plinth. I notice an E-Bay seller in Taiwan is offering a Teak plinth cut for the SP-10. Anyone bought one of those?
All comments welcomed!

Hi Lewm,
That is interesting info on the L07D. As for my budget concrete plinth- I suppose I would have to make sure that the 'slab' I buy is able to be cut without crumbling. I regularly see workmen cutting driveways and the like with a water protected circular saw arrangement. The tonearm hole would be easy, the space for the SP10 could be tricky.
What about a material like they use in kitchen benchtops? Nice colours too!

You mean Corian? The scuttlebutt on Corian is that it does not sound so good as a plinth. This is only word of mouth information. I think Jean Nantais is one person who tried Corian as did some others with Lenco tts. Don't give up on concrete, IMO. Maybe you can make a mold and cast a piece with a square opening for the SP10 chassis.

Hi Lewm,
No, Corian. I read up on that- it's really some sort of polymer (Ie plastic). I also saw that people had tried it and it made a poor plinth- plastic is very unsuitable.
Think terrazzo. That's a sort of fancy concrete with pieces of marble through it- looks great! Other aggregates might be good too.

Someone has suggested perspex with a layer of another material, like aluminum or wood. Not sure about perspex- reviews of turntables plinthed with the material don't read well.

I make slate plinths, under the OMA name, so obviously I am not unbiased. And I HAVE listened to an SP10 with no plinth. Which is why it strikes me as rather absurd to go that route. Same with people who like a skeletal or box plinth with decks like the Garrards. I started making slate plinths first for my own SP10, and at that time you virtually could not mention that you used that deck, as it was so out of fashion.

In any event, I found the difference between using slate, and the wooden plinths I had made, or one of the Obsidian stock plinths which I also own, was so impressive that I began making slate plinths for other decks as well.

Running an SP10 without a proper plinth, and with a separate armboard, is a very bad idea.
