Dear David,
As Ecir38 mentioned, a lot of your answers are to be found in earlier postings where the arm-pods are shown in the 'raw' cast form with all the holes and cable entry points clearly visible but re-cap:-
1) Aluminium is too light and mild steel is magnetic. I needed to make sure that the arm-pods could not be easily moved once the geometry of each arm had been established. I investigated machining stainless steel, brass and bronze but they all need up costing about $2000 each, so I went for casting (either brass or bronze) and bronze is cast here in foundries on four out of five days of the week compared to limited casting of brass.
2) Arm-Pods are solid except for 55mm diam hole in the centre to accommodate all the arms I could think of?
3) See previous photos.
4) I just meant to make sure the table was level by using packers under one or more Tip-Toes.
5) Yes the shelf is 33mm thick laminated particle board.
6) Not practicable. Apart from all my running around to organize, the height of the pods are determined by the height of the turntable you are using.
SME recommends that the mounting height of the arm is 41mm below the level of the platter although most modern arm are mounted 30-35mm below the platter.
I found that with vintage arms, a height of 47-48mm below the platter allows for more flexibility in getting the arms level.
7) Screwed spikes were drilled and tapped into the bottom of each pod. The are chrome plated brass and are leveled by screwing in and out.
Sorry I can't be more helpful but you are really asking me for my 'intellectual property' which took me 3 months to design and have fabricated.
Good luck.
