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

Lewm, I had the same impression from Ralph's arm mount description and the same sense of caution.

In ongoing design for my SP-10 plinth, I'm intending to bolt down the armboards (2) with brass machine screws. Each armboard will be 3/4" thick and replace that section of the top 3/4" layer of birch ply. The idea of cutting off the end of the plinth then reattaching the arm somehow sounds questionable to me.

Ralph, concerning how big, you might want to read some of Jonnantais' experiments with various plinth materials and size.
