Is it possible to get brass shiny using a vibrator type tumbler?

I have a vibrator and use walnut husk media. I also have used Dillon
brass polish.

The brass comes out clean, but it has a dull flat patina to it.

I would like to have it shine like new. Is this possible?

Thanks.

Bob

I use the vibrator I got from Midway years ago. Also only have used the
ground up corn cobs. If I leve the brass in it for several hours it will be
very shiney.
Looks like new brass if you don't count the dings in the case.

Use ground corn cob and Dillion brass polish.

Yes. Change the media to corncob. 20-40 mesh works nicely, and
doesn't stick too badly in the flash holes.

I believe most people use corn cob media for polishing. Me, I don't
bother. A hole in the X-ring doesn't care how pretty the brass is.

some type of vibrators have a closed shell (? correct word?) You can use
whit it a liquid cleaner, sometime house cleaner work well for brass, whit
less expense that famed firm product of gun's accessories vendors

I have tried all kinds of cleaners and vibrators and corn and walnut
media.
Anything gets the outside clean right away. But after days of
vibrating, the primer pockets and inside the necks is still dark.
I can get the inside of the necks with a bore brush wrapped with steel
wool and spun in a lathe, but the time it takes costs more than new
brass.
I have tried the ultrasonic with Lemi Shine and some distilled white
vinegar.
That works a little better.
There is a guy on the internet called "kombayotch" that uses a ceramic
media. He is a very smart guy, but I have already wasted too much time
to purse the clean brass.
I can clean the outside of the necks and shoulders with steel wool and
and few twists of the wrist. It does not look good, but it works fine.

I have a large bowl vibration unit that I use ceramic material to
knock off the sharp corners of cut steel. Will round the edges and
provide a patterned figure on the faces. It would be to strong
for brass. I round hardened steel.

I'm not all that sure the flash black on or off makes a difference.

A clean primer hole and flash hole is important.

I can polish the brass with a wheel and rouge but that's all work. I
want the vibrator to do the work.

I'll try the corn cob media and see if that is any better.

Thanks.

Be careful about what you use to polish cartridge cases. Some polishes
contain ammonia and will leach copper out of the brass weakening the case.

I once used some brasso on a rag to shine up a handful of Arisaka cases.
All the ones I polished split on the next firing but I got several
reloads out of the rest of the batch. Later on I found out about the
ammonia problem...

Now I only use Midway polish but clean is good enough for me, I don't
need shinny.

I am using a Lyman vibratory tumbler. Not that the brand of tumbler is
important because it is the media and the polish that cleans and shines the
brass.

For a number of months now I've been using a coarse corn cob media that is
sold in pet stores as "lizzard litter" or "small animal litter" for polish
I've been using the NU FINISH car polish (the liquid in the orange bottle)
sold in WalMart and other stores. The brass and the nickel cases come out
looking beautiful. Advantages I have found with this so far are, slight
reduction in cost, coarse material not as dusty, coarse material less likely
to block flash-hole.

There are prepared corn cob and walnut hull medias on the market Dillon
sells some and Lyman has its' own and so does Frankford Armory(?) some even
have jewelers rouge impregnated in the media. If you use it be careful,
allowing your brass to sit in unagitated rouged media can cause the stuff to
cake in the bottom of the case and block the flash-hole causing misfires and
many other problems.

When you use the corn cobs check on it about every 2 hours. If you let it
go over night while you sleep, it should be very shiney.

Do not add any thing to the corn cobs. I have added some paint thiner a
couple of times to cut the dirt out of very dirty brass, Not too much ,
maybe one or two caps full at the most.

Just leave them in there long enough and they will come out with a mirror
finish so long as they are not water stained when you put them in. That type
of corrosion takes a buffing wheel to remove.
I often leave my Lyman Turbo Tumbler running overnight with 60 to 80 30-06
cases in it Works great. My wife also uses it for polishing her little
ornamental brass knick knacks she has around the house.

I use ground corncob blasting media that I bought at Grainger's (don't
remember if it's 14/20 grade or 20/40), in an old Thumbler vibrating
polisher that I bought on eBay. I add a little powdered jewelers
rouge; just enough to turn it kind of pink but not red. If you use too
much rouge, it still works but is very messy. I usually tumble them
overnight.

Lyman Tuff Nut is walnut media with too much rouge added. You can
dilute it about 60% or more with untreated corncob and it makes a nice
mixture.

And of course, watch out for graboids.
