Specific Instructions.
First Grind
: Run the Tumbler for 24 hrs. and slowly open the
Barrel Lid (#28)
, releasing the
small amount of gas that builds up during the process. Check the stones, which might show
a little rounding, but not much. Clean the seals and close. It is important to release the gas
as it will turn thicken the abrasive slurry. After another 24 hrs. check again. If the slurry is
thickening, add a little water. Run for one hour and check again. If it is still thick, add some
more water. Let the Tumbler run continuously, but check daily. Continue this process for 7-10
days to remove the sharp edges and rough areas. Be patient. This is the most important
step. When all of the edges are rounded you are ready for the next step.
Note:
Between steps you must clean the
Rubber Barrel (#22)
and stones. Pour off the slurry
into a disposable container (ie: milk carton) and take care that the stones remain in the
Rubber Barrel (#22)
.
Warning!! Never pour the slurry into your home plumbing system.
Next, fill the
Rubber Barrel (#22)
half full with water and remove the remaining slurry.
Next, remove the stones into a clean container or plastic bag. Finally, fill the
Rubber Barrel
(#22)
1/2 full with water and clean out the remaining slurry and grit. Wipe it clean with a wet
paper towel and then wipe it dry. To clean the stones, gently slosh them around in clean water
and remove them a few at a time checking for breaks or cracks. Discard broken or cracked
stones. Place the stones in a plastic colander, or old nylon sock and rinse them completely
off. There should be no slurry or grit remaining on the stones.
Second Grind:
Carefully replace stones into the
Rubber Barrel (#22)
. If the
Rubber Barrel (#22)
is less
than 1/2 full, add plastic pellets (not included) to make up the difference. Add medium grit
(according to the chart on page 5) and water to the bottom of the top layer of rocks. Reseal
and tumble. Run it for 2-3 days before checking. They will begin to smooth. After seven
days they should have a smooth finish. If not, let them go another 2-3 days. Clean again as
you did after grind one.
Pre-polish:
Place stones into the
Rubber Barrel (#22)
adding the correct amount of pre-polish and plastic
pellets (not included) if necessary, and water. Let it run for a week, checking every other day.
After a week take out 2-3 stones to test the progress. On a dampened piece of leather, old
rug, or towel, sprinkle a small amount of polishing compound, and rub the stone vigorously
with it. You should see a definite shine in a few moments. If they shine, clean the
Rubber
Barrel (#22)
and you are ready for the last step. If not, pre-polish and check in 24 hrs.
Operation (continued)
used to take the jagged, sharp edges off of small metal parts. To polish brass, gold, silver, or
copper, use polishing media designed for that specific purpose.
