I have a pair of ceramic tweesers I have used a couple of times.
They seem to work OK; I can’t say anything yet about how they hold
up to dropping or how long they last. I save them for very small
work where heat conduction could be a problem. I also purchased a
couple of pair of spare tips. The problem was the tips are secured
with an unusual cross tip screw that requires a special tool to
remove. I didn’t see the special tool listed in the Rio Grande
catalog from which I ordered the tweesers, so I made a screw driver
that would fit by grinding the end off of a small phillips head
Normally, I use titanium tweesers which can take quite a bit of heat
and don’t seem to poison my pickle.
When I solder jump rings, I hang them on a drafting pencil lead.
Some brands of lead (really graphite) can be seasoned with the
torch. Gently bring them to a red hot heat, allows a waxy material
to burn out. Staedtler Mars brand works for me. Some other brands
use some kind of polymer lubricant that explodes when you heat it.
The leads, available from my local art supply store fit a 3/32 inch
chuck and can be reduced in size at the tip by turning them against
an abrasive. I then place the end that was not reduced in size into
the mechanical drafting pencil and hold everthing in position using
Since I have completely changed the subject by now, I might as well
go on…with small jump rings, I am usually hanging them on the
graphit pencil lead to hold orient the solder joint away from other
delicate pieces: stones, lever-back springs, etc. I use the Rio
Grande “Cold Shield” gel to keep those things cool when I need to.
The gel comes a bit too thick to apply smoothly, so I thin it with
water, mix well, then put it into a glue syringe. This allows me to
easily get the gel precisely where I want it. I think the
additional water in the gel also allows me to apply more heat before
the gel dries out and quits dissapating heat as well.
Just a few thoughts…
