Well I don't have a very well tooled machine shop at all,
but my first soldering iron had a brass or bronze tip,
and other people have remarked about how new tips
don't last as long as rare or unobtainable brass ones
from times gone by.
I can't say how good this is yet since I just made it
and will compare it to the other tips as far as wearing
out goes. Brass is supposed to be copper and zinc,
but just about any other yellow alloy using copper
may also be called brass, and dark coppers bronze.
Another reason I want to make soldering tips is that
I plan to try to make a very tiny soldering iron for SMD's
that I will have to solder under a microscope for
interesting one-time projects. One such project
may be phonographic (sounds groovy!) in nature.
Step 1: What you need
Tools and Parts. Here are the ones I used:
1.A regular moderately cheap soldering iron.
(not the 99 cent ones that melt in your hand though)
2.A brass rod similar in diameter to the iron's non-brass tip.
3.A rotary motor tool kit like a dremel.
7.Something not very important to solder the first time.
