I believe there is much confusion about Raul's table, possibly due to his non-English native language, although I think he communicates quite well.
I attempted to include a link to a photo of his SP-10 but cannot figure out how to do so. It is a wood frame which surrounds the motor unit and extends to one side to provide a mounting area for the arm. In answer to the OP, this is a secured fixture between the mounting for the motor/platter casing and the arm base. It is NOT a separate arm pod so that is not what he is recommending as an alternative. His solution is only this minimal frame (possibly 3/4" thick) to hold and position the arm, plus three suspension feet underneath the motor pan, and not a more massive plinth as most others have constructed.
If I may be allowed to continue speaking for Raul, his position is that a high mass plinth is not necessary for good performance with an SP-10 Mk 2. I have been using a similar mounting for my Mk 2A for over a year with pleasing results. Whether this is inferior, as good as, or better than a more massive plinth I cannot say -- I haven't tried one yet.
But two discussions have developed within this thread: comments on separate arm pods as ask in the OP, and the question of desirable plinth mass, now with an even further diversion by Weisselk in suggesting the removal of the controls and electronics outboard with only the motor/platter attached to the plinth (whereby I assume he eliminates the cast mounting frame for the motor, electronics, and switches). Hopefully all this discussion may be useful to the OP and he/she is still reading after all this time. ;-)
