Wiring Pencil

"Wiring pencil" sounds like you want to *draw* conductors. Maybe someone else has heard what you want called that. I assume you mean these:

Any tool distributor will have them. Parts houses too. Looked on flea-baby?

a wire wrap tool and accessories?

Farnells does 'em. Surely they've some presence in the US?. The spooling wire is really good for fine repairs.

might

They should be available in the US (providing they don't give them some esoteric name over there).

If all else fails then it won't be too expensive to get one from the Old Dart

Never heard of Farnells or wiring pencils, but a Roadrunner is either an automobile or a leggy bird.

Perhaps the Vector Slit-N-Wrap tool, P/N P-184? Carried by the usual suspects, Digikey etc.

AIIIIEEEEE!!! NO NO NO NO NO NO NO!!!! I got stuck having to use one of those once, and they're a nightmare. For one thing, all they're good for is daisy-chaining, and the resulting daisy chain is all wrong if you ever have to unwrap just one or two connections. And you need a special chisel to cut the wire at the end of a run, and you have to waste a few inches of wire when you start a thing, etc, etc, etc...

No. Avoid "Slit-n-Wrap" like the plague.

No special chisel required although I think that you're right, the tool did come with a flat-bladed cutter back in the dark ages when I got it. Haven't seen that gizmo for years. A good set of wire cutters works just as well (better, perhaps).

But it is Da Bomb for daisy-chaining. I rarely use it (or any wire wrap) nowadays but I do have a "duty" CPLD on a break-out board with

spooling

Of course, it must have been an automobile then cos these RoadRunners have a brake as optional. I haven't seen any "leggy birds" with that provision.....

I've done some daisy-chaining in my day, but I soldered wire-wrap wire point-to-point. I filed the rivet off the blade of a WSU-30, and clamped the blade in an X-Acto handle. I'd strip a few inches of insulation, solder the end to the first pin, then loop the wire around and lay the insulated part of the wire along the path I intended to take. I'd grab the wire there with the tweezers, slide it into the stripper blade, and slide that chunk of insulation right up to the joint. Then, of course, the insulation was exactly the right length for the next joint. If I needed to daisy-chain them, I'd just keep doing the same thing. These sockets are all already tacked on Vector Pad-Per-Hole, of course. :-)

in the US called "Newark-In-One" or some such.
