ROCK TUMBLER
ASSEMBLY & INSTRUCTIONS

Production Introduction:
Smooth rocks that you find along riverbanks and other bodies of water did not start out
that way. In nature, a rock’s rough edges are polished away over a long period of time as
water and sand or gravel repeatedly washes over it to reveal inner colors and composition.
By mimicking this natural weathering process, this Rock Tumbler can turn rough-edged
rocks into smooth shiny stones showcasing intriguing colors and patterns in a matter
of 2 to 4 weeks. Junior geologists will love seeing the everyday rocks they’ve collected
transformed into shiny works of art and exploring how different types of stones and
different tumbling conditions can yield unusual results.

Phase 1: Starting to tumble
The purpose of this first cycle of tumbling is to smooth out sharp points and edges. This
cycle will take from 2 to 4 days, depending on the size and hardness of the stones. It is best
to check the stones daily during this cycle.
1. Rinse up to 4 ounces of rocks with
water and then place the rocks into the
barrel.
2. Add the Coarse Grinding Powder.
3. Add enough water to cover the
stones. DO NOT overfill!
4. Tighten the barrel cap to prevent
leakage (See figure 1).
5. Put the barrel into the tumbler by matching the size
of the axle to the size of the slot. The barrel correctly fits
into the tumbler in only one way. Be sure the tumbler
and the outside of the barrel are clean and dry. Cover
the barrel with the safety dome (See figure 2)
6. Attach the DC plug into the tumbler and then plug
into 110/220V wall outlet (See figure 3).

for your necklace, key chain, ring or earrings.
2. Using the glue provided, secure the stone
into the setting, gently close the prongs to
hold it in the setting mount. Let dry for 24
hours.
3. To attach the mounted stone, use a jump
ring connector. Twist the jump ring apart slightly with long-nosed pliers. Attach the
polished rock in its setting and squeeze the jump ring together.

Helpful hints:
– Tumbling rocks makes a lot of noise. Because of the safety dome and the shape of the
tumbler, a lot of noise is generated downward. Placing your tumbler on a sound absorbing
material will minimize the rock tumbling sound. You should also place your tumbler in a
place in the house where the noise will be least disturbing.
– Removing barrel lid: Before putting the lid on the barrel, it is a good idea to take a
lubricant and lightly coat the inside rim of the lid. This will help tremendously when
removing the lid between operations. Holding the rim under hot water for several minutes
also will aid in removal of the lid.
– Once tumbling is started, you must continue until finished. Contents left standing in the
barrel will harden into a cement-like mass.
– It is always better to operate the rock tumbler longer if you are in doubt. It will do no
harm to the rocks. In fact, it will give them a better finish.
– Tumbling rocks of the same type together will produce the most highly polished look.
