Thumler's AR2 Tumblers
The AR2 is a heavy duty tumbler designed for years of use. This tumbler has 2 rubber constructed barrels with plastic lids held in by an 'o' ring. It is belt driven and has a cooling fan and automatic safety turn off feature. Specifically engineered to run quiet so that these tumblers can be used indoors, and in apartment buildings. Thumler's tumblers require very little maintenance, and take about the same amount of electricity as a standard 60 watt light bulb. The double barrel system is wonderful for siblings to be able to tumble on the same machine and label their barrels. They are also extremely beneficial if you are keeping one barrel for each stage of rock tumbling to be able to re-use some grit and eliminate contamination. For questions about this or any of our machines please give us a call toll-free at 888-762-5746.
Purchase From Rockpick Legend Co.?
aren't just another business we're rock enthusiasts! Rick got his
start in rock and mineral collecting in 6th grade
when he was tasked with a science fair project that took him into a
tiny rock shop on Redwood Road in Salt Lake City, Utah. The science
fair project turned into a hobby, which turned into a passion, a life
time of studying (including at the University of Utah, and Montana
School of Mines) and eventually led Rick back into that same small
store to work there and eventually take over. Now Rick, his wife
Anita and their children, grand-children, and in-laws run Rockpick
Legend Co. Each person here has found their own specialty niche in
the rock world, and we offer a complete rock experience! From our own

Questions & Answers
How loud are Thumler's Tumblers?
Thumler's tumblers are slightly louder than Lortone but are still
quiet enough to be ran on the kitchen counter in a home or apartment.
The plastic lids account for the volume difference between the two
brands. The only exception to this is the Model B Thumler's which has
a solid metal barrel that is completely rubber lined. This tumbler is
extremely quiet when kept full. For 10 more reasons the Model B is
our favorite tumbler go here.
How much electricity does a Thumler's Tumbler use?
The smaller Thumler's Tumblers use about the same amount of
electricity as a 60watt light bulb, and the larger ones use twice
that. This is because Thumler's have much larger motors than Lortone
tumblers do, which makes them more difficult to overload, and makes
them last much longer. The trade off however, is that you'll use 2 to
3 times the amount of electricity to run them.
How long does it take to polish my rocks?
It takes 4 solid weeks to go from start to finish in any rotary rock
tumbler. There are four different grits or "stages" of rock
tumbling, each takes 5-7 days. At the end of each cycle you take the
rock out of the barrel and wash everything, add the correct grit for
the next step, and seal the barrel up again. You can see a noticeable
difference each week when you wash out the barrel; however they will
not be shiny until the very last stage is completed.
Can I open the tumbler between stages?
Yes! It does not hurt anything for you to open up the tumbler and
check on your rock. If the tumbler is all the sudden louder than you
expect it may have too little water in it, so you may want to open it
and check on the water level. Kids love to see the process and it's
perfectly fine to open the barrel every 15 minutes for excited young
eyes! (Caution: be careful to not contaminate the grit with other
How large of rock can I polish in a Thumler's rock tumbler?
It depends on the size of rock tumbler you have, if you are using a
3lb rock Thumler's tumbler (AR1 or AR2) you can tumble up to 1”
rocks, and fill the barrel 3/4ths of the way full. This means you can
tumble about 3 cups or around 40-60 1” and smaller stones (of
course if they are extremely small there will be more than 40-60
stones). If you are using a 6 to 9lb rock tumbler (AR6 or AR18) you
can tumble up to 2” stones (or about the size of an apricot).
How many rocks can I polish at once?
In a 3lb tumbler (AR1) you can polish up to about 3 cups of rock at
once. In a double 3lb tumbler you can do twice as much. In a 9lb
(AR6) you can do up to 8 cups of rock, and in the AR12 you can do 12
cups of rock. In the Model B you can do between 12 and 15 cups or
rock at once.
What if I polish the wrong type of rock?
The worst case scenario is that your rocks will disintegrate in the
tumbler. Regardless of the type of rock you tumble it will not hurt
the tumbler. Some rocks may not polish and some may be so soft they
disappear completely, but you will not damage the tumbler. Specific
types of rock can have acid in them similar to stomach acid which can
cause the lid to pop off. If this happens refill the barrel and add
baking soda or Tums to your mixture. This will prevent acid from
building up and the lid from popping off.
How can I tell if my rocks will polish together?
Take two rocks and scrape them together. If they leave equal marks on
each other, or neither rock is damaged you can most likely put them
in the tumbler together. If one stone leaves a larger mark on the
other, then they should be tumbled separately. This is the part of
rock tumbling that can be considered a learning curve, and may take
some practice. Remember that softer stones or rock that doesn't take
a good polish can always be re-polished separately later. (Caution:
Mixing very hard stones with soft stones may cause the softer stones
to disintegrate in the tumbler.)
What are the plastic "beads" I received with my tumbler
Rocks wear down during the tumbling process. Because of this, filler
is needed to bring the barrel back to 3/4ths full level. Plastic
pellets are the perfect filler. Besides providing volume, they
protect your rocks from chips and scratches. Use plastic pellets in
the "polish" stage to help achieve a professional gloss! We
include them in our kits to ensure your rock tumbling success.
Is my child too young for a rock tumbler?
Rock tumblers are recommended for children 6 years and older. With
adult supervision, they can be exciting and fun for children of any
