some arm boards on the Cain and Cain version for example are actually not attached to the plinth on which the table is found but to what i gues you could call the sub plinth. also i have seen people who have drilled a hole (in both slate and wood examples i might add) right through the plinth and then put there tonearm on a tower which at first glance appears to be part of the plinth but is actually seperate. also some arms like the dobbins plinth are at the back and i'm actually unsure if they are attached or not.
as to what to make the plinths of that is an interesting issue as the science behind it seems fairly dodgey. i am in the process of building mine and this is a brief synopsis of what i know.
a) mdf should be avoided
b) marine/ birch ply should be ok
c) solid wood is also ok maybe think mix and match (ebony high density with maple med density)
d) slate alos works but be careful to over damp
e) avoid lead shot etc
the last idea is from a web site that re does electric guitars they reckon the secret to good tone is proper laquer/ french polish finishes as per old gibsons (i gues that is what piano's are all about too). these guys re laquered copy/knock off gibson's and said the tone improved remarkebly.
