touching the Barrel Lid (9). This will
prevent the Barrel Lid from rubbing
against the housing and will reduce
friction.
To open the Rubber Barrel, remove the

Barrel from the unit and then remove
the Knurled Nut (7) and the Washer (8).
Next, remove the Barrel Lid (9).
note:
7.
It is imperative to load the
Tumbler with the proper amount of
materials, or the process will not be
successful, and the motor could be
damaged. An underloaded barrel will not
lift rocks up the inner side walls allowing
the cascading effect. Also, the abrasive
material in an underloaded Tumbler
will tend to form a slurry and will not be
effective. An overloaded Tumbler will not
allow the rocks to cascade. Lastly, too
much water will cause the abrasives to
float and not do their job.
“Charging” a barrel means loading it.
8.
Charge your barrel from 1/2 to 3/4 full.
More pointed or abrasive rocks or stones
will require closer to 3/4 full, leaving
a 1/2 full barrel when it comes time to
polish.
note:

During tumbling, the stones will
be somewhat reduced in size.
Choose stones that are similar in nature.

They should have a mix of sizes ranging
from small (3/16” to 3/8”) to large (3/4”
to 1”). 25% of the stones should be in
the smaller range. Split the remaining
volume between medium sized (3/8” to
5/8”) and large sized (5/8” to 1”) stones.

process. First, use a silicon carbide
grain, 60-90 grit size. Second, use a fine
silicon carbide grain, 220 grit or a little
finer. Next, use a 600 grit silicon carbide
grain or a pre-polish. Lastly, use a polish
of Tin Oxide, Cerium Oxide, or Titanium
Dioxide. When tumbling hard materials,
it might be necessary to repeat the
steps.

the top layer of rocks.
13. Seal the Rubber Barrel and replace the
Barrel Lid, Knurled Nut and the Washer.
14. Set the Rubber Barrel on the rollers and

sure to check the Lid seal during the first
ten minutes to make sure the tumbler
isn’t leaking.
