I went through the usual labour pains before I decided on mine. Rather than
going the cheap way I splashed out on Thumler's UV10 (Industrial) and so far
I have not regretted it.

Take them out to where the water is. Took mine just on a side trip and
there are all kinds of colored volcanic glass in Escanaba Mi.

Lost me Ig. You had a mill stuck in a corner with your lyon tool box

Extended warranty! You can reach little no neck monsters from Ill.?

I just chuck a plastic container in my lathe that has a couple of wood
slats mounted on the inside of it and run it at the slowest speed. I
use the tailstock to hold the lid on. It also works great for deburring
parts.

isn't this a metal working group? to make a rock tumbler all you need is an
old BBQ motor, a couple of steel bars that you cover with tight fitting
flexible hose, and some bracketry to hold the mess - direct drive one of the
rods with the BBQ motor. use any plastic jar for the tumbling jar.

Right. Read something on Ball Milling. There's something more to it
than what Horrible Fright might tell... and it doesn't take two weeks to
"tumble" a bunch of dull, worthless rocks into shiny, worthless rocks --
It takes about 24-36 hours in an optimized mill. In fact, it takes about
the same time to change loads and wash between grit charges as it does to
do the actual grinding. If you wanted to do the whole job in three days,
you'd be working after midnight two of them.

When I was working in the sand and gravel business a salesman gave me a
sample of a urethane sheet that had an adhesive back on it. The product was
available in different durometer ratings and thickness'. Once applied to a
piece of steel it was extremely difficult to break the bond between the two.
I don't recall the manufacturer of the product. It seems like the ideal

Yes, that would be cool.

Pennies? Then your corncob media is what you want to use. Ceramic

copper disks with barely visible features on it.

Frankly..Id use crushed walnut hulls for the job, with a teaspoon of
Brasso tossed into the batch..and checked REGULARLY.

Try a tablespoon full. It spreads rather well and is simply a media

So far I am more impressed with the nut shells than with the corn cob. As
far as I can see the corn cob will polish clean brass but will not remove
stains. The treated nut shells removed most but not all the stains, did a
great job polishing the pieces (up to 3") but did little or no deburring
(minor scratches still apparent after about 8 hours).

The next batch I shall put some steel in the nut shells. What compound do
you use for steel? There is a ton of proprietary compounds out there. I hear
some people just put in a bit of turtle wax. I run the silica with just
water and dish- washing liquid with the predictable result of good cleaning
but flash rusting. I wonder if dumping in a bit of Evaporust would work.

But of course. Brasso wont hurt anything and it adds a bit of polishing
action to whatever you put in there. More for the softer stuff, less
for the harder stuff.

I tend to reuse walnut hulls for many years. Its not so much the sharp
corners..which after a while..are gone..but its a great carrier for
Brasso, etc. even when rounded off. Brasso is nothing more than a very
fine media in a liquid carrier.

As I said I tried a silica crystals cat litter on some steel parts. The
results were surprisingly good but if run dry, the silica dust is awful
and
if wet, clumping occurs (duh, it's cat litter!)

I want the ceramics for steel parts and also plastics for de-burring
brass -
I am not sure the nut shells will do that job well.

Yes..they do a pretty fair job, though for steel, it takes a while. Soft
non ferris stuff goes pretty quick

So far I am more impressed with the nut shells than with the corn cob. As
far as I can see the corn cob will polish clean brass but will not remove
stains. The treated nut shells removed most but not all the stains, did a
great job polishing the pieces (up to 3") but did little or no deburring
(minor scratches still apparent after about 8 hours).

Ayup. It has little or no ability to remove burrs in anything hard. Add
a bit more Brasso..another table spoon and it will likely remove the
last bit of stains..which generally are etched into the material..just a
heads up. Might not be deep..but walnut hulls have little ability to
actually remove much metal.

The next batch I shall put some steel in the nut shells. What compound do
you use for steel? There is a ton of proprietary compounds out there. I hear
some people just put in a bit of turtle wax. I run the silica with just
water and dish- washing liquid with the predictable result of good cleaning
but flash rusting. I wonder if dumping in a bit of Evaporust would work.

Are you trying to deburr, destain or what? Walnut hulls are really not
much good for anything as hard as steel, other than for putting a nice
almost matt finish on it. Ceramics are what you need for steel.

What are you trying to do with the steel? Let us know and Im sure you
will have a lot of suggestions..some even good.

Well, after appx. 3-4 hours of polishing, corn cob media did remove
stains from old coins (whole layer of oxidation). It did work very
well, just slowly.

What kind of Brasso are you guys talking about?

The liquid. Simply fill up a tablespoon with the stuff..maybe two..and
dump it into the media if its walnut hulls, corn cobs etc etc.

Works great, less filling!

Give it a couple hours at the least. Its a very fine abrasive, but it
works pretty damned well.

Brasso also has ammonia in it, which is the active ingredient in a lot
of copper fouling bore cleaners. However, it's only at 2-3% You can
google the msds. I've used exactly the same thing, Brasso on walnut
hulls, for a long time for brass for reloading. I now have some stuff
from Dillon.

Just their Rapid Polish 290, still in my 30 yr. old Thumler's Tumbler.
It works at least as good as Brasso, doesn't have the ammonia. They
claim it doesn't weaken the brass like Brasso, but I had very few case
failures loading .357 brass over and over for years using Brasso. I
lost my 50 lb. bag of walnut hulls in a move, so I'm using some Lyman
media right now.
