Operating Instructions for Raytech's
TV-5 Tumbler Starter Kit
Your new Raytech Starter Kit is useful for a wide variety of finishing applications.
Some of these applications include grinding & polishing "baroque" gemstones
from rough chips, smoothing & polishing preformed cabochons and small slabs
& polishing seashells. Raytech tumblers are very useful for smoothing and polishing
a wide variety of stones. They are particularly useful for finishing sawed
or ground to shape preforms where the surface of the stone must be smoothed
and polished without destroying the basic shape.
Your New Starter Kit Includes:
(1) TV-5 Tumble-Vibe Tumbler
(1) TV-5 Spare Bowl
(1) GS-H2 Stonefinish Kit

Health & Safety Cautions:
- Do not cover the machine with anything
such as a blanket or a box to insulate the noise as this could cause
overheating and eventually will become a fire hazard.
- Always connect the tumbler to a properly grounded outlet.
- This tumbler is not designed to "walk" during normal operation.
We strongly recommend that the tumbler be placed on a solid floor
and away from any combustible materials.
- Never attempt to operate this
tumbler with other than recommended medias and compounds.
- Never place
your hands inside the bowl while the tumbler is in operation.
Always unplug your tumbler prior to this step as this tumbler uses wet
applications and may cause electrical shock.
- This tumbler and contents within the bowl are not recommended for
children. If younger children intend to use this tumbler, we strongly
recommend adult supervision on all levels.
- Only one (1) bowl should be used when operating the tumbler. Never use
both bowls at same time.
General Set-Up and Instructions: Your new Raytech
Starter Kit comes complete and ready
to operate. Upon opening the box you will find
a motorized base, with (2) bowls, clear lid, and
(2) rubber nuts. Inside the top bowl you will find
(4) bags of tumbling grit that is labeled Step
1 -Step 4. Each step represents a different grit.
- Step 1=Silicon carbide Grit-l00/120
- Step 2=Silicon
carbide Grit-700F
- Step 3=Iolox 50
- Step
4=Raybrite TL.
These (4) steps take you from rough grind to
final polish. Take the top bowl, which contains
all (4) grits off the tumbler base, leaving one
bowl on the threaded shaft. Screw one of the rubber
nuts provided to hold the bowl to the tumbler base.
After tightening, there should be a bulge in the
rubber nut. This is normal and will alleviate the
bowl from vibrating off the base. Note: the larger
end of the rubber nut should set against the top
of the bowl. See photo depicting correct installation
of the rubber nut: . The working capacity of the
Tumble-Vibe 5 is approximately .05 cubic feet or
approximately 3 pints which also equates to a holding
weight of (4) pounds. We have included a spare
bowl with this kit, as it is common and recommended
that one bowl be used for your grinding and pre-polish
steps and the other bowl for your final polish
step. This practice will eliminate possible contamination
of the different grits. It is important to check the
tightness of the hardware as well as inspect the
interior of the bowl to ascertain any wear every
500 hours of use. Raytech tumblers are very useful for smoothing
and polishing a wide variety of stones. They are particularly useful
for finishing sawed or ground to shape preforms where the surface of
the stone must be smoothed and polished without destroying the basic
shape. It is recommended that the tumbler bowl be filled to capacity
for the tumbling action to be effective. If too much of the stone is
lost in the rough grinding step, it is better to make two batches of
rough ground rock and choose only the best of those continue with the
subsequent steps. The stones will finish the best if there is a mixture
of sizes included, A considerable portion of small pieces of stone is
very helpful in finishing the hollow areas. Note: Stones of mixed hardness
usually do not finish well if combined in the same batch. In most cases
it is more beneficial to finish only one type of material at a time.
It is good practice to scrub and wash the stones thoroughly between steps
to avoid contamination, thus the reason why we recommend a second bowl
as the rougher grits can become embedded in the walls of the bowl, retaining
the stones from being polished,

2 teaspoons every 12 hours. Rinse out sludge every other time grit is
added. New grit required as old grit breaks down and sludge no longer feels
gritty. |
If rocks are dry, add 4 teaspoons. If rocks are wet from rinsing, add
half the quatities above. If tumbling actions slows down from evaporation,
add enough water top restore tumbling action. Check every 8 hours. |
5-10 Days |
The Tumble-Vibe is especially useful for finishing stones where the shape should not be greatly altered, as with
sawed or ground preformed shapes. For fully rounding stones, Step One I is best completed with a rotary tumbler.

II
Fine Grind |
Silicon Carbide 700F |
2 teaspoons |
Same as above |
1-2 Days |
If soft stones are tumbled, this step should continue long enough
to break down the grit to a fine particle. At least 2 days will probably
be required after the last grit addition. |
III
Pre-Polish |
Iolox 50 |
2 teaspoons |
Same as above |
1 Day |
Eliminate this step with soft stones such as Dolomite, Malachite, Rhodochrosite,
etc |
IV
Polish |
Raybrite TL |
2 teaspoons |
Same as above |
1-2 Days |
Change entire load after 1 day. |
