HI,I am making a few boxed circuit. I am thinking of using a telephonejack so I can communicate between two boxes ( I need 4 wires) Untilnow it was good, telephone jacks are popular so they are fairly cheap.The problem is that I do not have any square bits that fits on mydrills ;)I mean puncturing a square on the side of a plastic box is timeconsuming. Especially if you are about to do 50+.Anybody have a trick to make fast and almost perfect square. Or evena round connector would be better, but I could not find any under 2$,Its only for communication purposes,Thanksken
