My DIY spiffy looking speaker cable guide..

I posted this in audio theory but kensmith brought to my attention that we actually have a DIY subforum for things besides speakers and subs.... so here it is

final product:




My materials/supplies:
-Canare Canare 4S11 star quad
-tech flex 3/8th
-heat shrink 3:1: 1x 3/4, 1x 1/2, and 3x 3/8.
-wire stripper




heatshrink order:
http://www.partsexpress.com/webpage....&WebPage_ID=73

partsexpress has nice, clean, heatshrink in my experience. Be sure to order the amount specified in my supplies list

star quad order:
www.bluejeanscable.com has cheap Canare 4S11 star quad, and they ship pretty damn fast

this is also where i got my locking banana plugs

techflex order:
http://www.partsexpress.com/pe/showd...number=082-336

TECHFLEX CONSIDERATION:
Theres a crapload of stuff techflex makes.
If you go with the stuff i used, its cheap, and it still looks nice
im gonna experiment with nylon multifilament, and clean cut flame retardant however...

http://www.techflex.com/prod_CCF.asp

http://www.techflex.com/prod_NMN.asp

nylon multifilament = super soft, super professional looking
clean cut flame retardant = nice white tracers, EASY TO CUT, a little bit finer threading/softer than regular techflex.

its up to you to use these.

ANOTHER NOTE: If you plan on making 12' cables, 3/8th techflex will SHORTEN BY A LOT. One spool of 25' 3/8th DID NOT make two 12' cables! I had to buy two spools! I got some 1/2" techflex carbon to see how it fit over the star quad, and it did okay, its a hair bigger, so watch out for lumps and stuff though.

1) Take a ruler or something to measure with, then mark the cable with a black sharpie at 6.5".* Do this at BOTH ends.

*Note: 6.5" is about the MAXIMUM length you can do w/ 6" long heatshrink. You can also do shorter of course:



2) Do this to only one side of the cable for now. Theres about 1/16th to 1/8th of an inch of gray rubber around the cable that youll be cutting off. Take a box cutter or something sharp and precise and sort of saw into it at a very slow rate, if you feel it tearing into the tissue like paper around the cable then back off. You should feel it when you are through the gray rubber though, its not very difficult. Also, feel free to bend the cable to open the cuts and make it easier to follow the slice all around the cable. Try to make the cut straight around the whole circumference of the cable, if it isnt, no biggie, gonna be covered up a lot anyways.



3) Tug off the rubber outside



4) Cut all the string and junk, the smaller the scissors the better. We will braid em later...




Then cut the end off of each of the wires, an inch or so is good, anymore and it will be a hassle to fit it into banana plugs and crap:



5) Slide the techflex onto the end that you have NOT cut yet. (This step takes a while)



When youre done it will look like this:

7) Cutting the techflex.
This part is if you made a 6.5" measurement *AT THE BEGINNING*. If you did a 6.5" cut, move the techflex down to 7" if you want to be safe, i would recommend going for 7.5" or 8".



first, run your hand TIGHTLY along the whole length of the wire so you get out all the lumps and crap from the techflex and to make sure its pretty tight against the cable. Then youre gonna cut about here WITH A HEATKNIFE:


if you dont have a heatknife, get a SHARP pair of scissors, cut it at that point, then use a lighter or a torch lighter (ones to start a BBQ), and then burn the frayed edges of the cut techflex with the flame (i use the side of the flame.. if that makes sense). It will melt and bubble quick if you hold the flame there for too long. I would just do it for about half a second... if you need more, do it for another half a second. Your experience may vary.

Alright, now slide the techflex on in the middle so its leaving the ends bare
8) Twist the wires, real simple:



9) NOTE: I used two black pieces of heatshrink, if you want, use a black and a red. I would have, but i didnt think of it until after the first cable was made, and wasnt about to have mismatched cables :P. Slide two 6" long 3/8th heatshrink tubes on the red and white twisted pair of wires, now youre gonna pinch the wire and find out where it goes from the rubber outer wire to bare wire, and youre gonna cut it about 1/8th of an inch from the transition point. Of course after its on the wire just use a heat gun or the torch lighter pictured above to shrink this sucker.. this is what we're aiming for, a little bit of overhang so you cant see any bare wire once you put it in banana plugs or something (you might not care however..):


10) BEFORE YOU DO THIS STEP MAKE NOTE WHICH ONE IS RED AND WHICH ONE IS WHITE. At the Y split in the cables, youre gonna have some showing, you may or may not want to cut about a half an inch of the 1/2" heatshrink tube and cover it up.
o that side

11) Almost there... take the 3/4th heatshrink, and cut a 1.25"-2" long piece out of it, then put half on the techflex side, and half on the y split side, this is what it will probably look like. If the "skirt" of the y split is too short, you'll be seeing white and red wire underneath it, and this is what step 10 was for:


12) Now repeat most of these steps for the other end of your cable that should still be untouched...

13) Enjoy your spiffy lookin cabes

Excellent tutorial. Someday I would like try making my own cables and tutorials like yours make it more enticing.

Thanks,
Paul

KUDOS to you sir. That is an excellent tutorial and even better cables. You sure get a lot of bang for you buck with DIY. I did almost the same pair except I used dual runs of Belden cable for a bi-wire setup. I even used the same Techflex.

i use 12ga outdoor heavy duty extention cable for my speaker wiring. It is heavy, well made, and the coating is flexable rubber instead of the stiffer, plastic coating. I bought it from northern tool for fairly cheap.

Be really careful when using bare metal plugs or binding posts on speakers. A power amp can put out enough juice to shock you. This can be hazardous if you have little kids around the house.

I also don't like bare metal because it's much easier to cause a short across them and some power amps don't like a dead short at all.

I've yet to try it, but Kegger tells me that the Home Depot low voltage lighting cable is quite a bargain and worth checking out.

I used 12ga. outdoor low voltage lighting cable at the Fest. Nice heavy stuff. Hardware store liquidation, 12.00 for 100 ft. Made the cables real long because I was unsure of the set-up. Forgot to cut hem down at the show. Ran 30ft. plus speaker leads. Couldn't have been optimal.

Doesn't look anywhere near as nice as these cables. I need to make some. Nice tutorial, Thanks.

Excellent tech write-up, Excellent cables. The outer wrapping was a beautiful touch.
