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. The instruction say: -dip in a solder pot which I don't have -use a soldering iron to, presumably, burn the insulation off which has never worked for me. Leaving soldering pots aside, the hot iron approach has never burned off any insulation even with tip temp's hovering around 1000F. Just doesn't happen. Maybe it's the soldering iron, maybe my method, but whichever, the enamel insulation just sits there. I end up using a file to scrape off the insulation which is tough on the wires and hard to predict when enough is enough. Any insightful hints? Thanks much. ...robert -- Robert G Strickland, PhD ABPH - KE2WY [hidden email] Syracuse, New York, USA ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

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. > > The instruction say: > -dip in a solder pot which I don't have > -use a soldering iron to, presumably, burn the insulation off which has > never worked for me. > > Leaving soldering pots aside, the hot iron approach has never burned off > any insulation even with tip temp's hovering around 1000F.

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.

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: [hidden email] <[hidden email]> On Behalf Of Robert G Strickland via Elecraft Sent: Friday, June 12, 2020 10:03 AM To: [hidden email] 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.

Robert,
Those instructions are for heat-strippable wire. If you have enamel or formvar covered wire, that must be mechanically stripped. 73, Don W3FPR On 6/12/2020 10:02 AM, 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. > > The instruction say: > -dip in a solder pot which I don't have > -use a soldering iron to, presumably, burn the insulation off which has > never worked for me. > > Leaving soldering pots aside, the hot iron approach has never burned off > any insulation even with tip temp's hovering around 1000F.

The old tried and true method is to use an X-acto knife to scrape the

Yes, that always works, BUT if you nick the wire, it will break,
especially on smaller gauge wire. For #20 and larger it is likely OK. 73, Don W3FPR On 6/12/2020 12:24 PM, [hidden email] wrote: > The old tried and true method is to use an X-acto knife to scrape the > insulation off with.

Thanks for the many replies. I should have mentioned that the wire to be
stripped comes from Elecraft in the K2 antenna tuner kit. Elecraft recommends the solder pot or the solder iron; they discourage using a lighter/flame. ...robert On 6/12/2020 02:02 PM, 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. > > The instruction say: > -dip in a solder pot which I don't have > -use a soldering iron to, presumably, burn the insulation off which has > never worked for me. > > Leaving soldering pots aside, the hot iron approach has never burned off > any insulation even with tip temp's hovering around 1000F.

A better way is to use an enamelled wire stripping tool! They are cheap and work much better than the other methods, which honestly were poorly effective for me for years. For my last project I bought the tool, it was a joy to use.

<The instruction say: -dip in a solder pot which I don't have> 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:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

I have suffered through the painful process of removing the enamel on the wire on just about all of the Elecraft kits..K2, K1, KX1, tuner’s etc.. I think I have made them all...just reading the comments here I was wondering why I never bought a solder pot as recommended...I checked out eBay and found several at around $30 USD,,why didn’t I do that 10 -15 elecraftyears ago and save all that frustration?? Chinese made, some 120 volt..perhaps will work for several kits...If I had it to do again..

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.

Ummm ... solder pot not required. All of the Elecraft kits I've built,
including my K2, used heat-strippable wire for the toroids. Small blob of solder on the iron, stick end of wire into it, wait a few seconds, when insulation bubbles and smokes, insert wire into blob slowly as far as you need to. End of wire is not only stripped, it's now tinned too. I used a separate larger iron I had that happened to have a flat-ish end which held a good solder blob but occasionally did it with my Weller Solder Station I was using for the actual soldering. I wiped it off every now and then when the insulation and rosin had accumulated. I did not find it frustrating at all. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 6/12/2020 2:01 PM, William Hammond via Elecraft wrote: > I have suffered through the painful process of removing the enamel on the wire on just about all of the Elecraft kits..K2, K1, KX1, tuner’s etc..

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.
