Anyone have some insight into how to create a brushed/textured finish in a vibrating tumbler? I am casting Bronze pieces of jewelry. I am looking to take a raw casting and place it in a vibrating tumbler and hopefully achieve a textured even finish on the surface. I would like to hide the porosity and imperfections within the textured finish. I am not looking for any polish or necessarily smooth finish. I would really like to avoid finishing each piece by hand.
Any suggestions on what type of media would accomplish this goal? Steel grit? Aluminum Oxide?
Any help is much appreciated.
Have a good one
