I am so honored to have “lurked” the forums for the past year or so
and excited to have a question worthy to throw out to you all! It is
so neat to know that someone’s going to have an answer-!
I’m just starting to incorporate hand-made chains (generally
open-link, delicate constructions in need of a final work-hardening)
into the custom work I do and need to invest in a finisher of some
kind… have been borrowing use of a friend’s GIANT rotary tumbler
and don’t need this sort of capacity for the one or two chains I have
going at a time.
My question is this- how are the tools sold by Otto Frei and Rio
Grande so different than the hobby-store rock tumblers or machinists
tumblers one can purchase at Harbor Freight Tools or other
hardware-type stores? In comparing items online, I saw a reference
to the multi-sided interior of the machines made specifically for
jewelry, and then one note on a lower-end vibratory tumbler that
said it did not have the amplitude to properly turn steel media…
does anyone know what the proper amplitude is? Or where I can find
technical info on the various specs for such finishing techniques &
machinery? I’m not particularly concerned about a quiet machine, I
just need a small capacity steel shot ready tumbler or vibratory
polisher at the best possible price; there’s got to be a reason
there’s such a big price difference from rock tumblers sold for $50
and the seemingly identical Rio mini-tumbler kit for $150.
The very last aspect of this question regards Argentium sterling
chains- is there any point to tumbling for hardness if I’ve
precipitate hardened my pieces?
I so appreciate any input; I have learned so much from everyone’s
posts! Thank you!
