I have been searching for a good media storage solution. I currently have about 200 DVDs and many more VHS cassettes, and plan on collecting more DVDs in the future. I think building a Flexy Rack is the best solution so far. My question is, do I need to use a 5/8" threaded rod if I'm only going to be putting DVDs and tapes on the shelves? It seems as though I won't be supporting as much weight and could get away with a smaller rod. Similarly, I don't care about "damping" the rack - I'm just storing things on it. As such, I don't think I'll be using neoprene washers. I'd like to make this as tall as possible, as I have a small apartment. There are 72" rods at my local hardware store that I could use. I also think I'll make the shelves 6-8" deep (If I make it 6", I can buy one 12" pre-made shelf and cut it down the middle, saving a bit of money). The shelves are 48" long. Do you think I'll have stability problems at that height? Does anyone have any opinions or advice on this? Many thanks!
