I need to replace the ancient plastic tumbling media that came
with my pre-owned vibrating tumbler. ... What's in there now is no
longer shown in the Rio Grande catalog..... I'm not sure what to
replace it with.
The newer media is heavier and far more effective than the old
plastic stuff. The clean cut media is very effective.
Rio has rounded cone shapes and triangle shapes available now
in their plastic tumbling media. Which shape is better for use when
tumbling sterling silver pendants/charms with an average amount of
detail? (little to no filigree or fine surface etching, etc.)
Your website shows cast pieces, most of which would finish well with
the cones. Since you are casting, You should probably use the pink
cones first to do initial cut down, then follow with the aqua cones.
However, your celtic crosses would finish far better with the
pyramids since they have a fair amount of detail.
And I'm also thinking of adding some stainless steel pins to
my stainless shot mix. Which size pins are more effective: 9/32" or
If you add pins at all, use the 1/2" ones and then only for the
detailed pieces, such as the crosses. Do not use pins for the
pieces that have much plain surface, the pieces will orange peel
from the pins hitting the plain surfaces. You can readily remove
the pins from your stainless shot with a decent magnet, like the
sewing stores sell to pick up pins from the floor. The pins
magnetize just enough when you run them to separate from the rest of
the shot. Use a plastic bag on the magnet for ease in separating
the pins from the magnet.
