I can not possibly take credit for these instructions but they are fairly clear and easy to follow. I did build a vaguely similar flexy though it was only five shelves, gloss black, and used brass look casters for ease of moving and cost me roughly $125 to make.For making flexy type equipment racks the instructions on the following thread are fantastic as a guideline for you can customize them without a problem.
