So here's a pic of my HT Rack. All DIY build. 3 Legs per stand. Wood is rough sawn old Ironbark hardwood from an old building in Murchison (country Victoria, Australia). Would have been originally cut and installed in 1850 as it was from the floor of the undertaker's business in the town. They are roughly 2.5" x 5". The wood still has the hand made by a blacksmith, square nails. Three legs, so always stable.
Shelves are 500mm x 500mm, Jarrah for the two left and right, and Bloodwood (ex Queensland utility poles) for the centre.
Each shelf is fixed directly to the legs via 2 x 150mm screws (countersunk into the legs and painted matt black so they disappear.
Don't know how heavy, but the middle rack needs a hand-truck to move.
I am still working on cable management but am heading to a system from networking, and just screw it onto the back of the rear leg, cables run up and down, and break out for each device.
Can send some better photos if you want them, but will have to be a few weeks away as I am currently travelling with work.
Need to get something better for the speakers to sit on too!
No Schiit on this rack yet, my Schitt is on a shelf in the office. But maybe some Vidars might find their way here!
Good luck with your search!
Cheers
Tim
