I was looking for a small, inexpensive audio rack for my system at work. The system is comprised of:
Proton 930 Receiver
Micromega Leader CD player
NHT SuperOne speakers
Goertz M1 1 Meter Micropurl interconnect
QED Silver Anniversary flat silver speaker cables
Couldn't find anything that met my criteria for stability, relative size required for a system that sits on my desk, appearence, and cost. This DIY project took bits and pieces of a weekend. The rack itself is 19" wide by 14" deep by 19" high. Cost was around $100:
Three butcher block shelves from Ikea @ $20 each
(2) six foot 5/8" #11 threaded rods at $5 each. Cut in half to make a 18" high rack.
24 5/8" nuts @ .30 each
20 5/8" washers @ .20 each
Three "tip toes "
One can of Tremclad Black HighGloss Spray paint @ $3
It looks as though you have built yourself one nice rack. During the past summer I was involved in a similar project and decided on Pennsylvania slate that I picked up at the local stone center as the shelf material. The slate pieces are approximately 23 X 19 inches and anywhere from one to 3/4 inches thick. I used rubber washers between the stone and the metal washers for cushioning. Drilling the holes for the rods was not as dificult as it might seem. In fact the stone center gave me one piece of stone to experiment drilling for free and the other stones were only about $12 each. The weight of the stones provides plenty of stability but make it difficult to move the stand.
