I was looking into buying a rack for a new audio system I'm putting together for my home office, but the cost of 'audiophile' racks made me choke. I was looking for a nice looking, decent rack without breaking the bank, and decided to build one. My total cost to build was probably about $250. If you don't go the spendy route I took buying stainless steel hardware, you can probably make one for about $75-100.
I had to buy more MDF than I needed, because my lumberyard only stocks 4' x 8' sheets, so I actually have extra material. Also, the great people at the fastening supply store I bought the hardware at gave me 6' all-thread rods instead of 3', which means I can build a second equally sized rack for the same amount of money.
You have probably seen Flexy Racks all around the web. My inspiration was a dual rack found at http://www.tnt-audio.com/clinica/flexye.html
. Full credit to the folks at TNT Audio for the great idea.
I decided to post clear instructions for a dual rack with measurements, since it's mostly a guessing game, and I love clear instructions.
