Lenco plinth? How big is too big?

I have an L78, upgraded Origin Live One arm, Empire MC-5 moving coil cartidge, and access to a sawmill with lots of prime cherry wood. I was thinking of a cherry plinth, 17 inches wide, 24 inches long, and six inches tall of cross layered one inch cherry. Then cut off the rear corner where the tone arm is mounted, in a sweeping arc of about 10 inch radius, and mount the tone arm on that detached corner. Use 1 inch thick isomolded graphite disks of 2 inch diameter topped by one 3/8" tungsten carbide ball, and resting on three such balls. Use three of these ball/disk combinations for each of the main plinth and the corner with the tone arm. What do y'all think? I would appreciate any suggestions before actually putting it all together. Thanks. Ralph

Win, I probably overstated the case for tonearm coupling. As you know, there ARE those who do advocate firm coupling to the bearing. However, your opinion carries a lot of weight with me (at least 200 lbs of slate). Anyway, I think we both agree that mounting the tonearm completely outboard of the plinth is not optimal. Like Pryso, I am also building an SP-10 plinth, so these considerations are very much on my mind, too. Ralph, I hope you get the picture.

Ralph, I am not sure I can properly visualize your method of mounting the tonearm, that involves cutting off a corner of your plinth. It sounds as though you intend to de-couple the tonearm mount from the major part of the plinth. There are differing opinions on this, but lots of smart guys think that the tonearm mount should be tightly coupled to the plinth and hence to the main bearing of the table. This sounds like a good idea to me. If my perception of your design is correct, you might want to re-think the mounting of the tonearm. Maybe Win and Jean can chime in on this topic.

I must have a particularly nice wife. Either that or she has a diminished esthetic sense. I've got three turntables sitting on the floor of our living room aka listening room, not to mention the one I use which is on the equipment shelf. And at the far end are the enormous Sound Lab ESLs flanked by huge and rather ugly OTL monoblocks. She never says a word, but she may be planning to kill me. No, in fact she's just a good egg.

Last spring I went a bit off the deep end, for me, as one who always wondered why on earth anyone would want more than one turntable at a time. I already had the Lenco and a Garrard 301 in a box in the basement. Then I saw a Denon DP80 in mint condition on eBay, at a price I could not refuse. Then I thought I'd better get an SP10 MkII, before they are all gone... And the beat goes on. I also bought an extra Lenco, because it was so nice and so cheap. Now I'm thinking I will have to sell at least one in order to afford to get the others up and running, but I cannot decide which one.
