View Full Version : Shiny brass?

How in the world do you get your brass to shine like new again? I use a tumbler (Lyman) with crushed walnuts and corn cob that I buy at pet stores. I also add a little liquid wax or chrome cleaner that is an automotive product. The best I can get is a lighter color looking brass. What am I doing wrong that won't produce that factory shine? Is there some more steps in the tumbling process that I'm leaving out? Or is it a fact that a tumbler won't produce this factory luster that I'm trying to achieve? I tumble about 4+ hours a load. :blink:

Time and polish. With your current setup you can achieve a shine but it takes a good polish like Flitz and many hours but I've heard "pet store" media is NOT the same beast.

What media should I be using then? And where can I find it? I've never heard of Flitz. Where is this polish found, is it an auto product? Do you add it to your tumbler, or polish your brass by hand?

Stainless tumbling.

I know that you're talking about doing batches in a tumbler, but when I was a kid, I used to keep individual cartidges shiny and new looking with a pencil eraser (yes, my borderline-OCD was apparent even as a child)...

Maybe you could try tumbling with a bunch of pencil erasers...?

I tumble with medium corn cob & a squirt of Cabelas brass case polish, it gets them bright & shiny but I let them run all day while at work or while doing other things.

I run them much longer than your average reloader, but I like them clean & shiny & I don't really care if I wear out a tumbler before its time. I intend to convert to stainless pin media when my current tumbler dies anyway.

Stainless tumbling.

I always thought stainless media was meant for those water tumblers. So you're saying I can use the stainless media in a regular ole vibrating tumbler? That would rid all that dust from the other media. And do you need to add any type of polish with stainless media if you use it in a tumbler?

Some people use some sort of liquid wash. Not sure how to make it though. I gave up trying to get mine to shine.

Stainless pins are for liquid tumbling.

Hornady tumbler, RCBS walnut media w/o any additive, and Flitz tumbler additive. I throw in a ripped up piece of damp paper towel to keep the media clean and the dust down. If I keep the number of .223 cases under 200 and tumble for about 4 hours they shine like glass, annealing marks removed and everything. I typically tumble 300 cases for 2 hours and they end up pretty damn clean.

This. I don't work with nasty brass EVER any more.

There's no real functional gain.... but if you take pride in your work, it's worthwhile.

Agree with markm that there is no functional gain. But the shiniest brass I ever got (looked brand new) was using Lyman's Turbo Brass Treated Corn cob, with a couple tablespoons of Frankford Arsenal's Brass Polish. I let it run only two hours in my RCBS tumbler. Both items available at MidwayUSA.

From what I have read Stainless is supposed to be the be all end all for recycling nasty brass into like new polished brass.

However if you don't have the setup it can get pricy.

I have found that (at least with dry tumbling using vibratory type) cleaning really bad brass with walnut helps a lot. The walnut is coarser and seems to excel at cleaning. However it can leave behind a bit of dust, and leaves the brass with a dull but clean finish. For mirror polishing I tumble again using corn cob with nufinish and mineral spirits. I also let it got a fairly long time if Im looking for what my dad refers to as "show grade" brass.

I use a Thumlers tumbler and stainless steel media and my brass looks brand new. Even old brass that has been sitting on the ground at the range awhile that gets gathered up will look new.

The only issues would be the initial cost, the time (as I tumble for 2 hours then drying time), the tumbler is pretty loud, and the pins get stuck in the flash holes every one in awhile (because I deprime before I tumble so the primer pockets get clean).

My friends are all amazed at how clean and shiny my cases are.

Yep... I run mine in the garage for 3 hours. Decap prior to tumble is almost mandatory. The primers will hold water and the pockets don't get clean if you leave burnt primers in the brass.

One more thing, tumbling with stainless steel cleans the whole case, outside and in, including the primer pocket. It doesn't matter in the grand scheme of things but it is helpful if you verge on being obsessive compulsive.

I'd love to get a Thumlers, but it's out of my price reach right after Christmas. Midway even has them on sale right now. I'm going to have to stick with the vibrator for awhile, and there's been some nice suggestions. I just don't like the lighter color finish of the brass. I seen some of the liquid tumlers on YouTube that looked really good. I was hoping I could get close to that look with the dry method.

I tumble with corn cob media for about an hour.
Run the de-prime and size die.
And then put the brass in a simple green hot water solution. Soak for about 20 mins and agitate it a few times.
Dry on a towell over-night. They come out looking good and shiny.

I learned a long time ago, get a "Universal" decapper, and do all (All calibers regardless) FIRST. The universal decapper doesn't resize, just decaps so you only need one. Then the primer pockets are cleaner, or if you want you can clean them individually prior to tumbling. Then they are all cleaned up BEFORE they get resized without any dirt on the outside of the case. I use a brass polisher added to my media. I still inspect each case after and with a paper clip or something small to make sure there isn't ANYTHING left in the flash hole. On my hunting brass, I use a flash hole uniformer before any loading/reloading.

Do any of you ever get anything in the flash hole with the liquid sonic cleaning?

I hear you. My initial investment was for the Thumlers so I didn't have money sunk into a vibrating case cleaner and media. Actually, the Thumlers was the first piece of reloading equipment that I bought. I had already started collecting brass before I bought a press and had three 5-gallon buckets full of range brass. So I read researched bought the tumbler and Lee decapping die at the same time and started decapping on a generous friend's press and then cleaning.

He had been using a vibrator also but switched shortly after seeing the results I was getting.

I like the Lee Univeral decapping die. I have that set up on a old RCBS single stage to decap anything that comes in the shop, then toss the casings in the tumbler. Probably half of the flash holes have some kind of media, walnut or corn. It's almost a job in itself cleaning the flash holes back out. I usually hit them with some air out of the compressor, but some of it is stuck in their pretty good & I have to poke something thru the hole to remove the media.

01-08-13, 15:52
For bulk AR loads I use corncob and Nu-finish car polish. The secret in my experience is do not OVERLOAD your tumbler. Make sure the brass moves aggressively. I my XL650/RT1200B combo.Tumble gain for up to an hour to get the lube off. Then load on the 1050.
My precision bolt gun Lapua match brass is deprimed, and wet tumbled in stainless media. I spin the brass in a media separator to through out most of the water then lay out the brass on a old beach towel and have my shop blower, blow warm air over them for a couple hours.

Yes it has a rubber end cap that is band-clamped on. The black duct tape was needed for traction.

Do you recall where you got the pillow blocks and shafts. Also how are you reducing the motor speed? I have a few electric motors here. I wouldn't mind making something like that.

If you do not wet tumble the media you use will make all the difference. Use plain walnut with dryer seats for cleaning. Then to polish/remove case lube use corn. You can add a polish or wax, but the corn will polish very well alone.

Dillon rapid polish is one of the best brass polishes i have used. Layman also makes a corn media called turbo tumbler media. My brass ends up looking as good as new.

Stainless makes the brass look better than new. The only thing corn can't do is clean the inside of the case. Cases like 45/9 come out cleaner inside, but not new.

Buy some corn, and use it after you size to remove the lube. I guarantee that by using the corn your brass will be much brighter than using walnut alone.

I read about using a weak citric acid solution. I tried it, and it made my brass really shiny, but getting the cases to dry in the rainy Pacific NW is a major PITA...

I shoot in a sandy area, so it probably gets changed after about 10-12 runs. ~Half or more of those are for lube removal unless I'm doing pistol brass.

A good price and a bunch on hand helps:
http://www.drillspot.com/products/521055/econoline_526040g-40_40_lbs_blast_media

This is fairly fine grain and does need polish, but it does not stick in the flash holes. 1.5 hours initial plus an hour to remove lube and add a little more shine.

Goood NIGHT! :eek:

Shoot... I change that crap once per year at most. I'm using Walnut in addition to the SS media package.

I'd guess an average of 5 loads per week... 250-300 loads per year. The media really loses its ZING after the first few loads... but it still works good enough for a long time after that.

I always wondered how long people use their media. It seems that it last a very long time.

Does anyone use the SS media in a vibrating tumbler? Or what about using a combination of SS and walnut or something else?

That homemade wet tumbler looks like it's made out of PCV pipe. I'm just wondering what size? It's certainly more then a 4" drain.

SS won't flow in a vibratory. SS needs water and soap to flow like lava.

I have to admit I've never tried putting the pins in the vibratory... but just observing mildly soiled walnut move too slow leads me to believe something as heavy as steel isn't going to do much.

01-09-13, 09:43
I get some abrasive sand (really tiny rocks) every time I pick up brass, but using the corncob to remove he sizing lube also decreases the life. But that's the fast no-hassle way to remove it.

Changing the media often is not a big deal, especially since there is no hassle of washing/drying anything. Just dump it out. A 40 Lb bag at $35 gets me ~15,000 reloads.

The Dillon lube adds some expense but really shines and slicks up the cases. Buying half a case at a time (split w/ Dillon lube) lowers the cost some.

You know, it might be worth a try to see how it works. Having walnut media with a handful or so of the pins. People put coins in vibrators all the time. I don't know about your media moving slow. Walnut shells in my Lyman moves around pretty well. Just a thought...

Mine are pins. I actually didn't realize there were other types but it has been years since I bought any media. That is the good thing about stainless steel, you don't ever have to buy more unless you dump them down the drain.

No.

AFAIK, the problem is that the relatively heavy steel pins just sink to the bottom of the vibratory tumbler, and then you have cases just bounding around on top of them.

This is why everybody uses stainless media with rotary tumblers...

Well, I did a little experiment. I tumbled some 9mm casings in a walnut media I got from a pet store with some turtle wax chrome cleaner added for 4hrs in my Lyman Turbo Tumbler. I got a clean casing, but was lighter in color and had a dull finish. Then I took the casings and stuck them in a plastic jar filled with vinegar and shook 'em a little bit, then sat them on the counter. Everytime I walked in the kitchen & seen them, I'd shake them a little more. I then let them soak for a day. This is what I got. The casings on the right had the vinegar bath, the ones on the left was tumble only. The casings in the pan were all vinegar soaked. Notice how dirty the insides are on the ones on the right. These were Speer Lawman shells, and they just shot dirty. My gun was pretty really dirty after shooting these.

This is about the only difference I can see. In the other photos the four cases look the same to me.

Anyway, I believe you. After I ran my old .40S&W cases through my homemade wet vibratory tumbler with a citric acid solution, they REALLY shined up. I have some stubbornly filthy/tarnished .30 Carbine cases that corncob isn't fixing, so I'm thinking of doing the same again...

BTW, I cleaned that dysfunctional old toaster oven yesterday, and I think it would be a great dryer (it was only the "toast" setting that didn't work).

When it warms up a little it'll be time to clean up the garage to see what I can scrounge up to build something like that. I know for sure there's some old skates out there for rollers. What kind of "citric" solutions are you using?

I had about 300 rounds of 30 Carbine shells I found in a couple of old ammo cases in mom's garage after she passed. They belonged to my dad, so they probably have been around since the Korean War. They were pretty nasty, so I threw them in the tumbler with walnut media, and then again with corn cob. Most of them look pretty good, but a few has tarnish stains that just won't come out.

The RCBS walnut shells and the Flitz media polished arrived late this aftn from Midway. I'll be trying that out soon. Everything I have now is pretty clean. It's time to start running them thru the press or shoot some more. There's an idea, 67° tomorrow in KY, good day to make some noise.

I followed the directions here:

The key is to keep the solution agitating, so I simply adapted my vibratory tumbler to be a wet tumbler:
I removed the bowl, cut down the threaded rod that held the bowl in place, drilled a hole in the bottom of a 5-gallon bucket, and then attached the bucket to the tumbler.
Then I put another bucket (without a hole) in the first bucket.
It was pretty top heavy, so I ran a tie-down from the bucket's handle to a hook in the ceiling, so it wouldn't tip over.

I let it run a while, then stirred with a wooden spoon, then let it sit overnight. Some of my less filthy brass came out better than new.

If/when I build a rotary tumbler to do stainless steel media, I think I'm going to use a couple 5-gallon buckets and a Gamma Seal lid, placed on top of casters. I have an electric motor out from an old shredder that should be able to turn it, if I gear it correctly. Or maybe I'll just buy a little cement mixer!

Hey, Bimmer...

I wonder if there's a Zip line tumbler that works like that Ammish guys Brass trimmer? :sarcastic:

Get one of those each, and you could be the poster boy that is scawnny in one arm, and buff in the other arm, with a high pitched voice. Wish I could find that pic. :sarcastic:

Oh Lord! :p

Here's what I do...

I strain off the water, pins, and brass in a triple level strainer I made...

Then I shake the pins inside the brass back into the drum. After that I drop the brass into a rinse water tote. Next I shake the water out of the brass and surface dry it on an old rag/t-shirt.

Then drop it into the dry tumbler for 30 min for a final internal dry/polish.

For mirror polishing I tumble again using corn cob with nufinish and mineral spirits. I also let it got a fairly long time if Im looking for what my dad refers to as "show grade" brass..

How much Mineral Spirits should be used when adding to cob media?
