Skeletal vs Plinth style turntables

Hi Dgarreston,

Your idea for damping the SP-10 frame is similar to what a friend (physicist) suggested to me some time ago to damp unwanted vibrations. He suggested using Devcon Flexane 60 to the underside of a surface to be damped. The listed properties include "absorb noise and machine vibrations". http://www.itw-devcon.co.uk/index.php?/devcon_mro/flexible_urethane_maintenance_and_repair_systems/devcon_flexane_60_80_94/

It would seem a simple matter to apply. It would not have the mass of your ingredients but if I understand the product, as an elastic material (does not fully harden) it would server more as an absorber for vibrational energy.

Comments?

A further point following Viridian and Ct. When I first became interested in DD tables Corian was often mentioned as a recommended plinth material. But then I read more than one negative comment on that. Further reading disclosed that Corian includes some amount of aluminum flake in its composition. Apparently that varies among samples and that quantity can have a sonic impact. Bottom line, simply choosing Corian may not allow prediction for how it will sound.

Unfortunately it seems to me the best answer is to follow Ct's path and experiment with alternatives.

Halcro, do you have any idea how that tower plinth builder now has access to bolt/unbolt the motor unit or change wire with the tonearm if necessary?

Form does not seem to follow function?!?
