Re: [Elecraft] stripping insulation from enamel wires
I have also used an electric solder sucker like this one: https://www.ebay.com/itm/362348659918 You plug the end with the bulb and remove the nozzle. Prop it with the opening for the nozzle pointing up and fill with fresh solder. There you have a mini solder pot. I bought mine for $10 or $15 back in the day and it works too. I still like my Knipex tweezers best but this is fast if you are doing g a bunch of toroids. I would still use the Knipex tweezers to scrape the ash off if any is left. Change the solder in the pot frequently. The wire comes out tinned too, an added benefit. Dave K8WPE David J.

Re: [Elecraft] stripping insulation from enamel wires
Ummm ... solder pot not required. All of the Elecraft kits I've built, including my K2, used heat-strippable wire for the toroids.

End of wire is not only stripped, it's now tinned too.

Re: [Elecraft] stripping insulation from enamel wires
Stripper machines actually sand/ grind off the insulation. Less chance of nicks. Burning it off is for the low temp insulation (think is called soldex) and works for commercial applications as the insulation acts like a flux. Most insulation (enamel, Formvar or polyamides) are high temp, 150-200C rating so much higher temps needed to burn it away. 200C wire can be almost white hot and still survive. Either careful scrap, don’t nick or use fine sand paper. Tin the bare copper after stripped.

Re: [Elecraft] stripping insulation from enamel wires
I have used the solder blob method with success. However, when I was building my K2 about 19 years ago, I used an old bullet shell casing for a solder pot. Secured it with vice grip pliers to hold it verticle, laid the soldering iron to side of the casing to melt the solder inside, then dipped the wire into the casing. It worked well. 73, George NC5G -- Sent from: http://elecraft.365791.n2.nabble.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] stripping insulation from enamel wires
It depends on whether your wire has "enamel" or "Ny-Clad" insulation. The darker enamel can be removed with a "paint-remover" like stuff that was sold in in little square bottles by CG and others. A quick search failed to locate any here, but I've got some somewhere (??) The lighter color stuff is probably Ny-Clad and will have to be sanded, or scrapped off as the enamel remover won't cut it. I find that some 400 grit paper with take off most insulation without damaging the wire as can happen by scrapping. 73, Charlie k3ICH -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Robert G Strickland via Elecraft Sent: Friday, June 12, 2020 10:03 AM To: elecraft@mailman.qth.net Subject: [Elecraft] stripping insulation from enamel wires Here's an old problem that I've never solved: how to strip the enamel insulation from wires for winding toroids.

Re: [Elecraft] stripping insulation from enamel wires
I've used four methods: - melt with a soldering iron - burn off with a small butane torch - scrape off with some very fine grit sandpaper - scrape off with a single edge razor blade All work, but I typically use the sandpaper or the razor blade. With sandpaper, I just double over the sandpaper over the end of the wire, squeeze, and pull the wire out. Sometimes takes 2-3 times to get it clean. With the razor method, I hold the wire down on the workbench and carefully scrape off the insulation, scraping toward the end of the wire. I find this gives me the best control of exactly how much insulation I remove. I just reposition the wire a couple times to get it all off. takes seconds, and is not hard on the wire (provided you have a light touch). Have wound many toroids successfully with all methods.

Re: [Elecraft] stripping insulation from enamel wires
Note that there is enameled wire that can't be stripped this way. The enamel is heat-resistant. Of course if you are using the wire that comes with Elecraft kits, you shouldn't have this problem. What I do is put a blob of solder on the tip of the iron. Then, I hole the END of the wire, which of course has no enamel on it, against the tip. That transmits heat into the copper, starting the process. Then I pass the wire through the blob slowly and watch the enamel boil off. Afterwards I scrape lightly with a knife to remove flux and burned enamel. This works fine with the iron set to 750 degrees f. If you aren't succeeding with an iron even hotter, I would suspect that you have the wrong kind of enameled wire. Incidentally, I use a second iron with an old tip for this. Having the blob of solder with flux boiling on it for a long time tends to erode the tip. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ On 12/06/2020 17:02, Robert G Strickland via Elecraft wrote: Here's an old problem that I've never solved: how to strip the enamel insulation from wires for winding toroids.
