BE ADVISED THIS KIT DOES NOT INCLUDE: De-burring media. We have had good luck with media from Harbor

* Finish on all parts is RAW steel. You can paint if desired.
BACKGROUND: We plasma cut lots of parts like large tabs and large
washers. The cheap vibrator type tumblers and roller driven tumblers
were just not effective and could NOT handle the heavy steel parts
so, we designed our own gear driven tumbler. This tumbler design is
so effective that we decided to share it and offer it as a kit.
You'll need a half inch drill motor and some basic hand tools but
we'll supply all the other parts like gears, bearings, brackets,
clamps, hardware, etc. Capacity is not rated, however, the tumbler
can easily accommodate 50 large 3 inch x 3/16 steel parts (plus the
de-burring media). SEE PHOTOS for "BEFORE" and "AFTER" pictures of a
shock tab we tumbled. This tab was tumbled with 20 other tabs for
2-3 hours.
DRILL MOUNTING: The drill mounting plate is highly universal and has
been designed to accommodate a wide variety of drill motors. Use a
good heavy duty variable speed 1/2 inch drive drill. We have had
good luck with a Black & Decker 7.5 amp 120 volt drill. Cheap drill
motors may overheat. Running your tumbler too slow may also cause
overheating because drill motors have an internal fan that needs to
turn at least fast enough to exhaust the hot air from inside the
drill. Check your drill for overheating and adjust the load or speed
if required.
CHAIN ALIGNMENT: Because the mounting plate is designed to
accommodate a wide variety of drills, you'll need to make sure the
chain is aligned correctly after your drill is installed. Be sure
the chain engages the gears smoothly and adjust the drill mounting
brackets as required to insure that the gears and chain are all
properly aligned. A mis-aligned chain will tend to 'click' or even
jump off the gears.
TUMBLING HEAVY LOADS: We have found that when the tumbler is first
loaded with a extremely heavy load, the drill may turn slowly or
unpredictably until the bucket has turned several revolutions and
the load has been evenly distributed. THIS IS NORMAL. Once the load
has been distributed evenly the speed will even out and may
increase. Adjust speed downward as needed. If you run the tumbler
too fast, you'll hear the parts bumping around (like tennis shoes in
the clothes dryer). When you find the correct speed you'll hear more
of a constant "whooshing" sound.
WARNING: Never leave machinery operating unattended. Keep clothing,
long hair, fingers, and jewelry away from moving parts. Keep pets
and children away from equipment when operating. Unplug from the
power source when not in use.
REPLACEMENT PARTS: The bucket is a common 5 gallon bucket, the chain
is a common bicycle chain. Most hardware is common. All parts are
available separately from us. Contact us if you do not need a
complete kit.
BE SURE TO SEE THE VIDEO BELOW. In the video, the tumbler is running
at medium speed. It can easily run much slower or much faster. We
have found 60 rpm to be very effective for de-burring most steel
parts.
