I'll be using T-slot extrusions for the frame and wood/Corian for surfaces. Work is in progress, the frame should ship from Bombay this week and should have a table in another fifteen days.
This is the frame being built at the moment:
The vertical uprights are the beginnings of stands for studio monitors. 8 uprights for two stands, and screen will be at eye level in the middle of the table (not raised platform).
Top will have a keyboard drawer suspended from it (not computer keyboard, MIDI keyboard) and that's pretty much it. Space underneath required to tuck in the PC and a couple of amplifiers and subwoofers.
Completed table has load-bearing capacity of 800kg, it would be twice that if the forward center strut had one more supporting member. Even this is overkill, but the best part about using these sections is that the whole thing disassembles into a set of bars = a tiny package, and is also infinitely customisable by adding more members and units. I plan on a top shelf above the monitors, and maybe angled extensions at a future date for soundproof panel mounting. Also, it saves me quite a bit on dedicated monitor stands - the table is lightweight and rigid, exactly what is needed for good sonics.
For reference, the bars are 30mmx30mm, so most of the structure and visible connectors will be hidden once populated with electronics and cables.
