I have been wanting to make my own soldering iron tips for as long as I have known how to solder.
There is always an odd shape that I can think of that is not available.
For instance, how about a tip that is forked, the distance between the forks being "just right" to enable you to heat up both ends of an SMD resistor at the same time.
Now I have been trying to find out what exactly is the magic plated substance at the end of a solder tip that works so nicely.
Has anyone done this? Did you make your tip form bass/copper steel? did you plate then end of the tip?
