Cool Bottlehead! Maybe some day I'll be skilled enough to try a build like that.

 

So I got some equipment delivered to the house yesterday. A new Weller wtcpt (old hand me down was shot), a panavise, star quad and a few different connectors. I'm excited to try my new equipment and create my new cables.  A few quick questions though...what is the best tip and solder for the project? Is it necessary to use flux on cables? I keep reading conflicting advice online. Thanks!

@Allanmarcus,  Do you have any experience with the BTG Audio 26ga wire?  It's only 30 strands, but I'm not sure if the polyethylene coating is any more flexible than teflon.  Most of the cable that I've stripped down from my local suppliers is 17 strand, so I'm going to have to go online for my IEMs.

Nope, sorry.

On the Weller tips the last number on them indicates temperature. PTM8 is 800 degree, PTP7 is 700, personally I prefer 800 but 700 will work for you. If you are doing large connectors like quarter inch, I prefer PTM8s, that is a medium width tip, for finer work something like a PTP7 or so would be good. You want to buy rosin core solder something like Kester .031 diameter SN60PB60. This is 60/40 tin to lead ration and has been a standard in the industry for many years. A good solder to start with. If you cannot locate the solder tips by those numbers I will look at some this weekend and get you better numbers. They change every now and then, Allied Electronics is a good source for some of these parts but Markertek should have them as well.

 

Occasionally you might need a little additional rosin flux but for most soldering, what is in the center of the solder should be sufficient. Remember to head the joint then apply the solder, this keeps you from burning off the rosin before it cleans the solder joint.

I read somewhere its a good idea to use some flux when twisting together some wire, then tinning the twisted wire before tinning. it. For example, I create headphone cables with 8 or 16 strands. That means I have to twist together 2 or 4 wires before soldering them to the connectors. I will twist the wires together, dip then in a little flux, then tin the wires (learn about tinning, if you don't know already - lot's of YouTube on tinning). I'm not sure if this use of flux makes anything better, but I'd like to think so.

Hey,Thanks Again Tom! Great info! Ill add that stuff to my order.

Thank you Allanmarcus! I don't know much about this end of our hobby, so I appreciate all the info. I'll ck out some Youtube vids.

I am sure there are some very good YouTube videos out there as well as some good forum advice. You need to consider the source on some things and be a little cautious. I have seen some scary YouTube videos and some very bad advice dished out by well meaning people.

PTM8 and PTK7 . I have used the PTM8 for many years but occasionally for really fine soldering I will go with something really pointed like the PTK7.

 

My setup is probably different than most, I will have as many as three irons going with different tips so i do not have to stop and change tips. I recently built several hundred 4 pin mini xlrs to quarter inch cpnnectors so i wanted at least two tip sizes. There is very little lost motion when I solder and being a bit ambidextrous with tools does not hurt as well. You can buy extra sponges for the Weller, new barrels, and entire new hand held irons that you just plug into the base. If you know what you are doing you can even change the heater element and switch inside the iron but that is not a job for beginners.

Pardon me if the numbers are slightly off, the actual solder has size on it in hundredths of inches, when you go to buy it the seller might describe it differently. If you have any trouble I will be working in my shop at home this weekend and I can better look some of the things up then. Generally I rarely use additional flux unless the surface is hard to clean with the flux inside the solder and that is exceptionally rare. Its use with a solder pot is another matter but you need to get some basics down before jumping into something like that.

If you have an old cheap soldering iron you're not using, but you don't yet have a hot knife to cleanly cut paracord and Tech-Flex, check this out:

Great idea, there are all kinds of hot knives out there, some for cutting Styrofoam or trimming feathers when fletching. This one is not expensive and would certainly do the job:

^^^^^

Hey guys. Thanks for all the great Ideas, tips, and suggestions. I picked up some of the suggested solder and a few different tips this past weekend while I was out of town. Im going to play around with making a few basic cables this weekend. 

Tom...thanks again!

Ill also keep the old soldering iron for the paracord. Thats a great Idea Musicfan!

 

Speaking of paracord...any suggestions on size?/ or any good sources? Can I just paracord over the rubber cover on the star quad or will I have better results braiding?

You can paracord over star quad or use smaller paracord for individual wires. 550 should be large enough for star quad but it can vary in size between suppliers. 275 is generally the size I use with 24 awg with jacket.

 

Better results...hmmm. It is probably more eye appealing to do a braid but are the results actually better than if you left the star quad in tact. I have used a lot of both and if you skillfully braid paracord, I doubt you would diminish the sound much compared to the original star quad. You cannot make music sound better than the original recording but you can try to not diminish what you start with. My suggestion would be to braid one using the wires from inside star quad, and then listen to it against the original. If you are equally happy with both results, do whichever one you prefer.

 

How you perceive sound is fairly subjective after a certain point. I have built headphone cables where I am happier with the result than the original cable and some where I could not tell a difference. Get some star quad, look up four wire braiding, and play around. 

 

Generally speaking if I do a braid, I try to use three wires if going trs to trs, four wires for balanced cables. Generally I use ofc wire but have experimented with Litz, OCC copper and silver, etc.

Does anyone know where I can get a decent stereo 1/4" female connector?

 

I need to make a decent 2' extension cable for my LCD-2 custom cable since it's a little to short for my desk. 

 

I need to make a 1/4" female to 3.5mm angled male cable.

Markertek carries Neutrik (Rean), that is what I use. If you need stereo I will put up a link soon. I also use Switchcraft, here are links for both brands, TRS and TS.
