I tried to find shelving at several stores that I could use and modify to fit my equipment. After many years of not quite satisfied I decided to build my own. I like boat anchors so I needed strength due to the weight and space around the equipment for cooling. My operating desk has 4X4'f for legs and frame.
Or... knowing someone that is a journeyman carpenter, experienced furniture maker and also a ham that understands what goes on the shelves can be helpful...
Newly constructed "vintage" operating position. All of the sets are restored, except for the SX-28. There are two of those in the cue. There is a ton of interfacing to be done between the equipment! But, it is moving along slowly. Other shots are of the main operating position--ARC-5 rigs awaiting restoration and the Hallicrafters and Navigator which are restored and operable.
The latest iteration farther replacing a small desk and a fold out table with a single table. Not my first choice in colors but the price was right....
