Title: Heat Guns for cable building
Post by: ThePiedPiper on August 27, 2019, 12:11:21 PM
I have a quick question for the cable builders on here. I purchased my son a heat gun to build/repair guitar cables, and hopefully to help me with some mic repairs as well.

The heat gun I purchased is this one:

Is that overkill for cables?  Should I get something like a heat pen (smaller) instead, something like this ...

If not either of these, what is recommended?

Follow-up (bonus) questions:

1- Is there a shield or heat deflector that is commonly used when heat shrink tubing near capsules to keep the capsules from getting too much heat?
2- On a separate topic I discussed TechFlex sleeves, which I like a lot, but they do hinder with the flexibility of the cable. Is there something that is a little thinner and a lot more flexible available for cable protection? I was wondering about the actual clothe braided cables that you sometimes see on headphones ... is that an option?

THANKS FOR ALL THE HELP!

I use a big, heavy-duty Wagner gun for my cable projects, but very carefully on the LOW setting.  I recommend that whatever you get, it have a dual-temp control just in case the one fixed temp is too high.  You can very quickly go from shrunk tubing to burnt tubing and wire insulation.

I don't have a recommendation for a thinner Techflex, but can tell you that it also will melt easily if you leave a heat gun on it too long.  I find the thinner diameters of it to be quite flexible.

Thank you for the knowledge!
