I had 2 pieces of steel cut and bent.
I welded the sides and added bracing to the bottom.
It weighs over 100 pounds, so I had to support it while I mounted it to the wall.
I made sure to mount the cabinet to the studs behind the wall.
I used Hammertone paint for the finish.
All hooked up. Vertical turntable with 70s Zenith Circle of Sound speakers and Bose 901 tulip bases.
