I’ve been reading all the posts about how to safely use a polishing
wheel with interest, since I don’t use one and have always been
curious about them. I know that they require careful use. I’m
wondering if such a machine would be useful to me (or whether
different use of my flexshaft would help).
Here is what I would use it for (at this point). I make mixed metal
pendants, and I always start with a back of either copper or brass
and mainly rivet (but also solder) components onto it. Two years ago
I designed three basic shapes and had them cut out of 18 g. copper
and brass by a local water jet place - it was not cheap but I have
never regretted it because it gave me many, many more pieces than I
could have gotten sawing them out - there was virtually no waste -
and I can make small but meaningful changes to these versatile and
basic shapes using files and saw. The time saved not having to cut
out every pendant back is huge, and it gives me a perfect,
symmetrically shaped piece to start with.
I use my flexshaft tool to finish the edges. All I use is sandpaper
in successively higher grit, starting with 220, then 400, then 600.
It gives a nice enough finish to the edge - it looks okay - but I
wonder if there is a way to get a more professional look, maybe even
using the flexshaft. Someone’s comment about the split lap producing
a “heavier” look to a ring edge piqued my interest and inspired me
to post this question.
By the way, many thanks for all the jump ring soldering suggestions.
I have read them all and have some good tips to try. But the most
important thing I got from all your posts is that my big problem
does not lie in what flux or solder or soldering surface or
soldering set-up I use, really. I realized in reading all your posts
that I am simply being lazy and sloppy because I don’t like
soldering jump rings (just call me Rachel "I’d-rather-be-riveting"
Rose). I’m probably using too much flux, and too much solder and not
being precise with either, nor with my torch. All things I can
remedy and with the many tips given in your posts, I should be able
to improve my technique. So thanks all.
