I’ve been RCing and soldering for years and the single most useful tool I have in my solder kit is a home-made solder holder. Now I won’t pretend this is my own idea as I’d read it in some RC magazine years back but it’s easily worth the few minutes it takes to make your own.
What you’ll need:
1) A ball point pen barrel with the ink/pen part, cap, and stopper removed.
2) A roll of solder
Step 1:
Starting at the writing end (or where that end used to be), wrap the solder around the outside of the pen barrel all the way along and leave a long tail.
Step 2:
Insert tail down and through the centre of the pen barrel until it comes out of the other end.
Step 3:
Once the solder is out of the other end you now have a easy pen-style solder holder. When you need more solder just pull from the tip and it will unravel from the outside.
As always, comments are appreciated.
