Prepping Parts
Remove any stringy bits and pieces from the parts. Use a hobby knife or flush snips. Clean out the cavities for the legs as they may have overhanging areas.
Rotary Tumbler
We recommend using two different rotary tumblers. This helps speed up the process and avoids mixing and blending the two materials.
Tumbling Medium
Use screws as the medium. Steel screws for bronzeFill parts and Brass screws for copperFill. Using different metal screws will differentiate the tones.
New Screws
You’ll want to use new screws - Old screws that are worn out will not give you as much abrasion.
To get this amazing finish, tumble each part for about 8 hours. So it’s best to do it over night.
Health & Safety
Be sure to tumble in a well ventilated area, wear proper breathing mask and gloves for safety.
