I have four vibratory tumblers going. One for aqua cones, one for
green shell, one for red and the other for the last cob step. I
was more curious as to what successful results others have found
from the ceramic polishing media. I'm wondering if there are
certain designs that seem to do well in this finishing media. As
mentioned, I'm not really happy with the results I'm getting. I get
a shine, but definitely not the same as the buffing with green
Michael - I’ve used the ceramic beads for finishing in a vibratory
tumbler. They do a great job of polishing - IF - you break them in
properly. I ran the batch of 3 sizes (necessary) for 4 or 5 days in
a closed system with about 20% scrap silver and silver I fused. It
was really dirty but cleaned up well. The break in step is required
but only once. It doesn’t matter if you polish gold, silver, brass or
whatever after break in.
Next - the ceramic beads seem to need very long run times. 24 to 36
hours. Use the recommended cleaning solution.
What they polish - pretty much everything - BUT - since they are
round they don’t get right next to bezels and such.
It is necessary to run multiple sizes of beads together. One size
Last - you have unlocked the key to mass finishing - one tumbler per
media. I don’t understand however, why you would run both red and
green buff. Or are they used red for yellow metals, green for white?
