I usually work on such oddball stuff, kind of given up on finding a source for patch panels and such and just make most of my own... Amazing what you can do with a piece of 20 ga., a shot bag, plastic mallet, couple pieces of round tubing for dies, and a couple body hammers!!!!!! Used to be a sheetmetal shop in town, they were a great source for cutoffs and weird shaped pieces....too bad they went belly up! Probably cuz they threw away too much stuff!!!!
