I got this off of the usenet. It was suggested that one gets
some old nail polish bottles and clean them out thoroughly with
acetone or nail polish remover. Don't forget to clean the
brush!!! Once you let this stuff evaporate, you can put liquid
flux into the bottle (like batterns) and then there you have a
bottle with an included brush that if you knock over will not
spill if you have the top on.
try the applicator bottles for platics adhesives. they have a
long needle like metal tip that lets you apply flux one drop at
a time. they don't spill and you can apply to hot metal without
melting the brush.
Good idea! I use batterns flux in a syringe (with the point
blunted). If I remove all the air I can dispense very small
amounts. They are good for applying flux to hot metal. If the
flux dries in the tip a little heat or warm water will let it
flow again. You can pick one up at a drugstore for under a
It's amazing how so basic a task can have so many variations.
Here's mine for what it's worth.
One of the many neat tricks I learned from GIA was that of
dipping my solder into flux before placing it on a preheated
piece. I almost never have to add more flux to the piece. I also
found a 2" round piece of flat plastic material, translucent
white color, (at the recycle store in the Boston Children's
Museum) which I marked on the back with a sharpie to divide it
into 4 quadrants. The quadrants are marked "S", "E", "M" and "H"
for super easy, easy, medium and hard. I put a drop of flux in
the center of the circle and my solder chips in the appropriate
quadrants. If I need more flux on the heated piece, I dip the
side of my tweezers into the puddle in the middle and use them to
carry the flux to the piece. Heat doesn't bother the tweezers
and their rigidity gives you control over where you put it. Added
benefit: an 8oz. bottle of flux lasts 4ever.
