Step 4: Start of the splice

Whichever wire is on top (closest to you) bend away (or back) and then down, the wire will make a upside down L shape around the back wire
<p>Thanks for posting all this info. but I was unable to find info. within it with regards to my prpoblem. Am wondering if you would be able to tell me why a connection would fail - I wanted to run a plug from an existing live wire so made a &quot;tap splice&quot; into the existing live no matter what I done the plug remained dead while the original wire outlets were OK/Live. It was not a bad connection problem - am I missing something?</p><p>Any advice you can give me on this appreciated.</p><p>Thanks</p><p>Mike </p>
<p>My first post ever on here and I cant wait to post my first instructable. The prototype is done and works. Message me if you would like a teaser. I love this site. </p><p>Alrighty: First of all, does the right hand wire wrap around the left hand wire? I so have you tried pulling this before you solder it? I build wire harnesses and this method was actually disallowed at the factory even though we dip every splice in a solder pot and adhesive heat shrink them. They just didn't hold sometimes depending on the situation and the person doing the splice and or the soldering.</p><p>I actually come up with a similar version myself (although I cannot be the first person to do this). I twist both wires around once and wrap them back on themselves. When you pull on the splice it gets tighter.</p><p>Also: same length of the strip and twisting stranded wire, in my opinion, are essential for function, strength and looks.</p>
<p>My father taught me another inline splice in the 60's. He called it a Western Union Splice. He had worked for Western Union while he was in high school. Here is a link to that technique. It handles longitudinal stress well and can also be soldered.</p>

<p>Nice job. I will use this on my next soldering project, THANKS</p>
<p>really helpful!</p>
<p>A good example of the pigtail splice in use is a picture contained in the instructable:</p><p>http://www.instructables.com/id/Super-Basic-Solar-Lighting-under-75/</p>
<p>Very good description of an age old procedure.</p><p>You don't mention twisting the strands prior to. I have found that the splice can be slightly smaller. The downside is the the end of each wire can protrude from the intended splice &quot;envelope&quot;. Still pre-twisting the wire is probably better.</p><p>I like to twist the insulation as I remove it. It does a nice job twisting the strands.</p><p>Why not use the iron to shrink the tubing rather than adding another &quot;tool&quot;?</p><p>If the heat shrink is slipped over the joint while it is still quite warm some shrinkage can occur.</p><p>Nice instructable!</p>
<p>Worked great!</p>
<p>Nice tutorial! Thanks!</p><p>I just used it on a project and discovered one shortcut that may help some folks: I had several wires already stripped before realizing I wanted to go this route and looked up this instructable, so the strips were slightly different lengths. If you line up the two wires like you're going to use the &quot;pigtail&quot; approach and with their insulation lined up (just like the pigtail picture in the intro), you can then snip both the ends off at the same time and make them EXACTLY the same length. Then just continue from Step 3.</p>
<p>lol i hope youre just bein a smartass cuz if not u may need to go back and redo 2nd grade </p>
<p>Thanks for this information I used it last evening and the joints look pretty cool and I can feel a lot more confident about them. Cheers</p>
<p>Thanks for the well-explained wire splice. Just what I needed to fix an on-demand hot water heater.</p>
This is well executed work &amp; the instructions are clear. <br>Love the pros &amp; cons section. <br>Why have you not mentioned the alternative simple solderless solution of using a screw down in line connector. Each wire can be gripped by two screws &amp; there is probably no need to make the twisted splice. Please comment.
First off, great info and thanks for sharing! I have a question regarding soldering and the heat shrink...I work with a lot of weather equipment, generally located in the middle of agricultural fields and battery powered, and often have to make quick repairs thanks to mice, deer, and other charming wildlife chewing through various wires. Could a splice like this be done without soldering, and with just electrical tape in place of heat shrink? I realize it would be less than ideal, but field conditions are rarely ideal.
Unsoldered connections in the field will often (tempted to say always) become intermittent, unless they are made with a professional ($$$) crimping tool. Solder is foolproof and cheap. A good cordless iron will help you solder perfect joints in the field. Butane fired irons will shrink your HST after you solder your connection. I prefer soldering with a good cordless electric and using a cheapo mini-torch (or lighter, or match) for shrinking HST. Soldering will insure your repair doesn't become intermittent after exposure to humidity allows corrosion to begin.
This method of splicing has been around for many years, and is known as a Western Union splice.<br> <br> <a href="http://wiki.answers.com/Q/What_is_a_western-union_splice" rel="nofollow">http://wiki.answers.com/Q/What_is_a_western-union_splice</a><br> <br> As for lap soldering....yes, it works. But as the experts say, solder is not designed to make a mechanical connection - only an electrical one. Wires should be mechanically secured before soldering. A lap solder joint should not be used for heavy duty connections or heavy-duty use.
we have discussed this in other comments WU splice is generally accepeted around here as being |||x||| and this is more like xxxxxxx googling the term western union splice turns up both, but the first one more often :)
A Western Union splice is more like ---|||xxx|||--- so it is like the joint you are showing, but on each end the wire is wrapped 3 times around the other wire. Either that or my Radio Shack Dictionary of Electronics is wrong.
Just wondering what is wrong with simple lap soldering? When don't right they are very strong and quick to produce.
If for some strange reason your wire heats up so much the solder melts your joint could come apart without a mechanical connection to keep it together. Then there is the issue that in order to do a lap joint you might have to hold 2 wires, a soldering iron, and solder, which is more hands than most of us have. But I do lap joints myself.
FYI, if you use heatshrink tubing that contains an adhesive, then using this method will yield a neat <b>and</b> waterproof join.
+1 to that, adhesive lined heatshrink is pretty much the best stuff ever.
Until you want to take it off.
Only every time you have enough wire to do it that is.
Nicely done! Thanks.
My friends used have me wire thier amp because i never burnt one up simply because i insulated the wires and sldered where necessary these joints as i like call them twist up like a boobie lets call them wire joints western u8nion is so yesterday and RCA what have they done for me lately
This is &quot;yesterday&quot; technology. &quot;Western union&quot; describes the method rather than the splice itself. &quot;Wire joints&quot; sound vaguely &quot;chronic&quot;.
I love the &quot;Your electronics enabled buddies will nod to you&quot; bit! <br> <br>LOL
I'm always using the &quot;pigtail&quot; connedction when wiring most things as it's easier to work with. I just overcome the &quot;ugly&quot; insulation by folding the connection over after soldering, and taping the connection to part of it's own length of wire. In fact, (seeing i hate working with heatshrink) i find taping &quot;inline&quot; connections more messy and prone to tape &quot;sliding&quot; along the wire and exposing the connection. It's just personal preference i guess, and when you're doing it all the time, you will develop your own quick method
Also, when soldering in line, or even in general, if you've got time, it does help to &quot;tin&quot; the ends and just solder them together rather than twisting them - as that degrades the integrity of the actual wire. It's good for proper professional connections - if you ever find yourself in such a situation.
Thank you so much for posting this. I was tired of all my connections coming apart easily and looking bad. With this method, the results look professional. In the photo, I had to add a LED inline with a fan to indicate when it was on. If I had tried to pigtail it, the results would have been bad. ~thanks~
Great information in the instructable! It might be helpful to add any notes about the soldering itself. Is soldering this splice any different then any other splice? A link that might be helpful to add, http://www.instructables.com/id/How-to-solder/ thanks for the great work!
Personally the improvements that this can make in a install or project far outweigh the time consuming part. Sure the pigtail/wire nut/soldered/twisted joint is easy, but it looks bad. I have been doing these joints (WU and just inline wrap RCA) for years while others wimped out. I try to spread the word and show them. Good job showing others how to do it right and make some projects cleaner and less tape gooeyness to go around.
nice trick and i think clean work is totally awesome... own heart satisfy when work to be done very well..
hey thanks for making me feel like an idiot, J/K...well a little, I much cleaner than my usual method Thanks
This is great! I've done my share of electrical repairs over the years, and I've ALWAYS pigtailed. This seems like simple, common sense but it's hard to let go of habits. I did this once purely because I didn't have a wire nut and remember thinking how much more sense it made, but once properly supplied I went right back to pt without even thinking about it! Beats the hell out of those cheap inline &quot;bullet&quot; style connectors especially!
From my experience: or you can use a &quot;ENVIRONMENTAL BUTT SPLICE&quot; its what we use in the aviation field works very well and weather proof might cost a bit more but a good investment. (quick google and might find a site like ...http://www.edmo.com/index.php?module=products&amp;func=display&amp;prod_id=18887 ... never bought or delt with them but its what im talking about)
Nice,thanks. I didn't know there was a name for this method. I just instinctively used this method to save on wire and tape!
Useful tutorial. Thanks.
So simple! Everyone needs to know this. Thank you for sharing!
I have been searching for days now, and came upon this in a google search. I am hoping you could help solve this issue: I'm trying to redesign my home stereo system so that I can mount my new speakers. My problem is that I don't have enough inputs, so I am splicing a few wires here and there to make what is basically a patch panel for all my stuff. Normally, this isnt a problem for me, but it became one when I went to splice some of my spare cables, and realized some of them had 2 wires inside, and some had three... And no matter which way I would join them to their own kinds, somewhere along the line I would need to join some 2-wire to some 3-wire... Anyone got advice on this? The 2-wire ones have the inner coated wire surrounded by the first wire, and the 3-wire ones are just 3 separately coated wires covered by the outer coat... Any help would be greatly appreciated!
**UPDATE**<br/><br/>Ok... I went and took a slight nap. After I woke up, I started a bit of testing with some of this. Its not like the spare cable wasn't replaceable...<br/><br/>Anyways, this is what I found out after some testing:<br/><br/>The 3 wires in the one cable were colored Red, Yellow, and Black. The other cables, and previously mentioned, were one wire coated and surrounded by the 2nd. I scrolled through google a bit more and saw that black was pretty much the same as the wire surrounding the first one in the 2-wire cable.<br/><br/>So I twisted red and yellow together, and twisted that pair to the single inner wire on the other cable.<br/><br/>That worked, and pretty well. The only down side is that it is mono by default. Thats not a big issue for me, seeing as im going to mostly use this &quot;patch panel&quot; for linking more speakers to different places easily. I am pretty sure most of the speakers I have are one channel each... ('Course, if they are multi-channel by whatever freak chance, that'd be cool =D )<br/><br/>Anyways. Now I guess the bigger question to ask would be if its possible to make it a stereo splice... I have several ideas, but they dont make complete sense...<br/><br/>If you have any info, please let me know. I hope this little bit of info helps someone else, too!<br/><br/>(If you want me to take some pictures with detailed instructions on any findings I make, including this one, feel free to contact me... Not like I got much of anything else to do for a few weeks...)<br/>
