Dear Judy: The last time I used the vibratory tumbler to polish
pattern sheet, I ended up with all those tiny grooves filled with
polishing residue that dried as hard as cement. I did not see the
embedded residue until after the pieces (A LOT of them!) were rinsed
and dried. Toothbrushing, soaking, solvents, etc., would not remove
it. Only manual scratching out of every little line would work, and
there was far too much texture to consider that option. I ended up
dyeing the grey residue with black permanent marker! The effect was
nice, but certainly not what I originally intended. I believe I was
using the Rio aqua cones; if not, it was something similar. I have
not dared to use the tumbler since on any etched material; and it
would be great to use it. I'm doing more and more etching. I have a
large series approaching that point (of finishing decision) now. What
would you suggest? Do you think it was just the drying that hardened
the residue to the point of irremovability? Have you experienced
residue in the grooves, and if so, how did you remove it? I don't
have an ultrasonic. I don't have a rotary tumbler either, but am
considering one if I can decide on which one to buy. I would only be
using it for stainless steel shot. (I keep hearing nightmare stories
about the tumbler turning silver black, etc., that is delaying my
purchase) I used a rotary in school with no problems. I was told I
could use my vibratory for steel shot, but it doesn't work. The steel
is too heavy. It just rolls around the bottom, and the work pieces
roll around the top.
Tips welcomed!
Thanks
