Tumbling Media- Corn cob vs Walnut
« on: May 02, 2011, 10:48:40 AM »
I know there are some of you with far superior knowledge when it comes to this sort of thing.  Is there any reason to go with one over the other?

I do use walnut occasionally because it seems to last longer than corn cob (really tarnished brass). Most of the time I use the washer and dryer and it works just as good with no sifting afterwords  ;)

I'll post a video later this week or early next week showing how simple it is.

I use walnut shells because I can get a bag at petco for cheap.  The cheap corn cob that I get gets stuck in .223 brass.

I use the corn cob... because... it's what my mentor always used.  When the tumble times begin to get longer, I add a little of the refresher stuff and it will extend the life.  I think i asked him once, his answer "it's what I've always used"

Unless you are shooting the fleas off of a knats ass and/or competitions, I would go with whatever is cheapest.  (the corn is probably GMO, so you might get mutations in your brass..... j/k)

I use a product called Lizard Litter, that we get at the local PetSmart pet store.  It's ground english walnut shells.  It's cheaper than the stuff branded as tumbler media and works great.  I put a capful of New Finish car polish in the 2 lbs of media that my tumbler takes, and stir it in good.  Makes the brass nice and shiny, the way I like it.  :)

I have used both corn cob and walnut - both work, find the corn cob is cheaper - but does not last as long.  Also I add some brass safe cleaning agents to the mixture to give it the shinny like new look.  For the most part I just use walnut as I add new material when the brass takes too long to clean.

I have heard of people using steel pellets or extruded rods to clean brass.  This media has an indefinite life span.  However, to use this media you have to add water when cleaning the brass.  The brass will come out clean and shinny both on the inside & out.     The downside is finding a method to mix the water, brass, and steel rods...some have reported to be using small cement mixers.

Well I'll have to try out this Lizard Litter... cheaper is good.   I guess I'll be swinging by the pet store on the way home tonight!

Question about the New Finish polish, does it contain Ammonia?  I heard somewhere on Youtube that it causes the brass to become more brittle, which doesn't help.

I have heard of people using steel pellets or extruded rods to clean brass...

Does this include steel shot for shotguns?  I think I might know where I can find some of that for free...  Would you just put it in the tumbler, or is it too heavy?

Ths product description on Amazon says no ammonia.  I could not find anything on the Nu Finish site that says definitively.  I've not had a problem in using for many years.  Maybe two tablespoons is all you need.  No experience with using rice, but I bet it might make my recipes taste funny.  :)

It's not steel shot for shotguns - the look like small rods I think designed for this specific use.

 Due to the weight of the cleaning material you have to add water to the top....Overall the total weight of water, metal, brass will require something with a bit of power to do the job right. Maybe a sidewider rotary cleaner might work, but when folks start using cement mixers it's going to be a bit too much for what most folks have.

There is I think a pre-soak phase - adding the brass to water with a bit of soap.

Here is an example photo's of before and after with what the media looks like.

Alrighty, so I went out to the pet shop and got some "lizard litter" thinking it was cat litter... nope, its for lizard's   :o  (Who would have thought?)   ::)

Anywho, so $7 worth is probably enough to last me the next 10 years.  I have a relatively small tumbler and don't use it too much, so that might not be best judge... But I use about 1qt of media in my tumbler, and I probably have 5 qts that I don't need yet.  Pretty good I'd say! 

The only down side to this stuff is the dust, it's pretty fine stuff.  I don't think it will cause any problems, but its just a little different than the expensive stuff.  I guess it did take quite a while before the treatment I put in there broke up too... it clumped up pretty good at first, and I had to scrape it off the bowl, but after about 15 minutes of running by itself, the clumps seemed to break up alright.

All in all, it did a fine job polishing.  If I had more money, I might try the official stuff next time, but that's a long ways off.

Glad it's working out for you.  The inexpensive cost of it is why I toss it without too much thought.  Also try strips of a dryer sheet in the mix.  That really attracts the dirt that the media scrubs off.

Thanks for the tip. I was surprised at how well the dryer sheet picked up the dirt.

I normally use walnut and lucked out by buying out an old reloader on Craigslist. He had two 5 gallon buckets of walnut that I doubt I'll get through anytime soon.

I thought I'd try using rice as a polishing media and see how it worked.  The result was all the brass policed up nicely.  However with the smaller casings like 223 the rice filled the shell and had to be dug out of each one individually, this took hours.  Even some 9mm cases had to be manually cleaned out. So it works in a pinch, but as long as I can get lizard litter I'll continue just eating my rice

Well update on the litter...

if you leave the lid off the tumbler, don't over-fill it and put it somewhere you don't mind the dust settling, that works pretty good as well...  Just keep the stuff dry!  It took a little bit of effort when I first treated it to get the clumps to break down, but now that it's hot outside it seems to work well.  I may put a small fan next to it next time to blow the dust away too...  You may want to run the tumbler/fan combo for a bit with the lid off it before you put anything in there to polish so you don't have any nasty stuff settling out with your dust though, just a thought. 

I tried the drier cloths, they did okay... I think letting the dust float away worked better...

i use rice but it doesn't last for long.  I use unmilled rice, not the milled one ready to cook.  The problem is that some stick inside rifle cases.  But i find it works well with pistol cases.  I also add a little car was to the mixture.  I use walnut on my rifle cases if I feel lazy but for me rice works better

Sorry some typo errors.  I also add a little car WAX, non ammonia, into the mixture.  My apologies.

use an used dryer softener sheet or 2 ripped into strips in with your media and it will pick up a lot of the dust and make the media last longer.

I agree with others that the walnut shells seem to last longer.  That's what I use in my old tumbler.

I switched to Stainless Steel Media and have never looked back. This is some range pickup .223 / 5.56 MM brass I found at my local club range that I ran through the Stainless Steel Media. This stuff was filthy. I used Dawn dishwashing liquid with a little Lemi-Shine and you can see the results. This stuff actually gets the brass as clean as new, unfired brass.

I'm with BillT,
I have been using the SS pins, a RCBS sidewinder and RCBS liquid media with hot/warm water and they work great.
You have to be careful when removing the brass from the stainless steel pins, the SS pins will get everywhere.
I use a standard spinning media separator and it works good.

The SS pins are a little pricy, but they last forever.

I get the same results as BillT.

They won't work in a vibratory type tumbler like the ones from Dillon. Stainless Steel Media must be wet tumbled by slow rotary action like the Thumlers Tumbler provides. It has a rubber lined drum that seals against any leakage. A vibratory tumbler will not provide sufficient agitation because the liquid combined with the media and brass would be too heavy.
