i'm building racks for some of my gear, and i'm considering just making the rails of wood. I've seen this done before, even on commercial products. Is there a good reason to go with metal rack rails?
I was trying to figure out the hole spacing to use for my patchbay and I kept getting different measurements off of different racks. To save you the trouble of trying to figure out the hole spacing use anywhere from 18 1/4" to 18 9/16". I used 18 1/2 to keep it simple and it works great.
