After a couple weeks of reading about the flexy rack, I've gathered materials and finished drilling and cutting the all thread. I was wondering before I put together the rack if there is any advice anyone can give. Couple of things I couldn't find at the local hardware store included acorn nuts but I was just going to substitute with a regular nut. I found neoprene washers but at 59 cents a piece, that would come out to be like 25 bux for the whole rack. Any substitutes I could use instead of neoprene? Is it necessary for neoprene washers? Also the materials I am using is 3/4" birch plywood, 5/8" all thread, and of course nuts and washers. The main thing it'll be supporting is a 160 lb 30" Sony widescreen. So are neoprene washers necessary? And also, any advice on painting the all thread, I finished painting that and the nuts using primer black Rustoleum spray. Should I add a clear coat or something to keep from striping the paint when I tighten everything?
