Vector also made a wire wrap tool that did not require stripping before wrapping: “Slit ‘n Wrap”. The tip of the tool had a knife edge that stripped the wire on the inside edge as you wrapped. They made a special wire that was sort of a cross between enamel and standard wire wrap wire. It was really quick because you could daisy chain from pin to pin without cutting/stripping individual wires. OK Machine Tool also made the “Just Wrap” which was a knock off of the same idea.

It uses insulated (_not_ enameled) #30 wire that must be stripped before wrapping. A motorized tool wraps around 0.25" square posts. The sharp edges cut into the wire to make a gas-tight connection. The connection is not soldered. Trust me -- Early in my career,I spent hundreds of hours making thousands of wirewrapped connections, and I even bought a Gardner-Denver AC powered tool for home use (vs. the battery-powered tools we used at work). I still have that tool, and a thousand feet of #30 wire, but I do little wrapping these days. The Vector tool is just a plastic "pencil" with a hollow metal tip through which the enameled wire feeds. You manually wrap the wire around a pin, move the pencil to the next pin, wrap that, and cut the wire. Then you solder both pins. The solder melts through the enamel to make a normal joint. -- 73, Mike N4CF Louisa County, VA USA Elecraft KX3 + KXPA100 @ 100W Elecraft PX3 panadapter Carolina Windom up 45' http://n4cf.mdodd.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
