Help IN the Sept issue of the RMC(pages87-88) they talk about a wire wrapping tool. The one they talk about is the Radio Shack Number 276-1570. I looked this up on the R?S site and they do not say how it is used. It looks like a jewelers screwdriver. How is this used with wires

The end of the tool will have 2 holes in it. A larger hole in the center that will accept the “post” that you will attach the wire to, and a smaller hole that will accept the end of the wire. Carefully strip about 1/2" or so of WIRE-WRAP wire. You must use the wire-wrap wire intended for this purpose. Regular hook-up wire won’t work. Insert the bare end of the wire into the smaller hole and place the wire and tool over the “post” that you will be attaching to. Holding the wire gently, spin the tool clockwise. The wire should wrap around the post, making a good connection. Note that the “post” is generally a square post in a circuit board or on a socket intended for wire-wrapping. Used as such, a properly made connection does not require soldering. However, you can spin a wire onto a stiff component lead and solder the connection. This works OK for hobby work and rigging up a quick circuit. It sounds more difficult than it is. Once you get the hang of it, you’ll have no problem. With perforated circuit board material, wire-wrap posts and wire-wrap IC sockets, you can build a whole circuit board for a project without the need to solder the connections. Wire-wrapped connections are easy to undo for troubleshooting or circuit changes. Hope this helps.
I did a real quick search on “dogpile”. The site below has some helpful sketches and tips for wire-wrapping.

I’m sure that you’ll find other sites as well, depending on on much you want to know about the subject. Haven’t been to the “Shack” for awhile but they may even have a little pamphlet on wire-wrapping. At least they used to have such things back in “the old days.” Don’t be afraid of it, I’ve built lots of circuit boards using just such a hand tool and wrire-wrap materials.

Chuck That is just what I wanted. I had never heard of this tool before. It looks like that might be a tool I could use,quick and simple(just like Me)
