I have a medium size Raytech vibrating tumbler. I tried polishing
some black coral in it using Walnut shell and was disappointed with
After 36 hours I only got a slight shine. I am considering adding
some Tin Oxide or similar cutting/polishing powder in with the walnut
shell to see if it speeds up the process. Has anyone tried adding any
extra compounds to walnut shell for polishing anything from metal,
wood or coral or do you have any better suggestions.
Or if anyone has any ideas for polishing Black Coral in the tumbler
I wouldappreciate the help.
It does polish nicely on a mop with a little white Dialux but Im
just trying to cut down my time at the polishing motor.
thanks very much
