Hi Gang, A little follow up on my note yesterday...
My new Jump Ringer blades arrived as expected from Rio yesterday,
and I set out to knock out a few more chains for a show next weekend
(yikes!). By the way, I'm using #12 half round sterling wire, wrapped
around a ~6mm mandrel.
Yesterday I emphasized the need to use plenty of lubricant, in my
case Burr Life. What I didn't mention is that I have been using the
blue, solid (waxy) form. Even with shorter coils, it occurred to me
that this lubricant, even liberally applied, could become spent by
the time I got halfway through the coil.
I decided to get out my bottle of liquid Burr Life and run a "bead"
down the slot of the cutting jig with the coil in place. The thought
was by applying the lubricant to the full length of the coil, the
effect would be sustained for the duration of the cut. It was a big
improvement, but then I encountered the inevitable drawback.
Of course, the cutting process produces a significant volume of
silver dust, or filings. The liquid Burr Life causes all the
jumprings and tools to become oily, and the filings to stick to
everything! Putting on my "thinking cap", I decided to place the
links in a kitchen strainer and leave them in the ultrasonic for a
while. A little help, but now I've got silver filings floating on the
surface, and I'm sure at the bottom of my ultrasonic, and I'll have
to clean it out... trying somehow to recover the filings.
I ended up taking the links, strainer and all, and spraying down
with household cleaner and running under hot water in the kitchen
sink. Didn't recover the filings, but the rings were clean enough to
use... but still had some filings on them! After finishing the chains
I run them for a few hours in a vibrating tumbler with stainless
steel shot and burnishing liquid, which cleaned and polished them
well. Someday I'll have to clean out the tumbler and try to figure
out how to recover all the precious metals (and a peridot gemstone
lost in there if there's anything left of it) from the burnishing
In conclusion... finally... I found the use of liquid Burr Life,
applied directly to the coil, to do a much better job than solid Burr
Life applied to the blade, but the clean up is a nuisance. If anyone
else has any thoughts/experience on this quandary, and recovering
silver filings from bearing liquids, I'd love to hear about it!
