polish for corn cob tumbler?

[Axis II]

I was at cabalas a few days ago and seen a bottle of polish that says add to a dry tumbler. I seen some posts about nufinish but is it worth the money to buy the polish? also does the polish leave a film on the cases that needs wiped off after tumbling?

I tumble now with a harbor freight tumbler and corn cob that's been used about 20 times and the cases still look cruddy. should I change the media or throw some walnut in there too?

Of course you don't need it, but with it the brass comes out brighter, it helps it glide through the sizer a bit better, and adds some protection. It does not need to be wiped off. Put it in and let the tumbler run a bit to mix it in good. Don't over do it.

I put a cap of NuFinish in mine, bit more for the first few goes and less and less as the cobs have absorbed it. Works well and priced right.

Corncob is used to polish, does very little on the cleaning side. Use Walnut hulls for cleaning. I run a 50/50 mix if corncob(20/40)/walnut hulls. This cleans better but the shine will not not be as bright as full corncob. The addition of polish into the mix does help, and leaves a protective film behind. For really dirty brass you can't beat the wet cleaners. Use a wet cleaner in a 5 gal bucket to clean your brass then polish it if you want the bling.

being super OCD about reloading I don't care for the crustiness on the inside of he cases and outside. the cob cleans it up a little but it looks nothing like factory brass. I might take a run to cabelas and try some walnut mix.

is it the silverish metal bottle? I got some. added at least 1/2 the bottle to the tumbler. was NOT happy with the first few hours of tumbling I got out of it. now i am very happy!!! I am re-tumbling a lot of stuff that I had previously been happy with

added at least 1/2 the bottle to the tumbler. was NOT happy

I bet. Bet it left a film. When I first added it, I added a teaspoon and got a film.

The main reason to add auto polish is to help keep the shine on the cases. Modern car polishes are not "waxes" at all, but modern chemical polymer coatings. Just like on an automobile's painted surface, the NuFinish places a single polymer over the entire surface. (Basically a single molecule covering the entire surface !) Since there are no gaps, breaks, or openings in the coating, oxygen cannot get at the brass to spoil the "shine". Therefore the shine stays on longer. Much longer !!

This polymer also adds some slight lubricity to the surface of the brass, which helps the sizing operation.

So if your polished cases sometimes stay on your shelf for weeks or months before being used, and you like the shine to stay in place over that time, then NuFinish will help.

I use walnut but I add a dollop of Flitz. Shines the heck out of the cases and does not leech any zinc out.

I have found corn cob media will take longer to clean the brass than crushed walnut shells but it will make it shine more. I have a bottle of Dillon media polish i use once and a while and it works well. I will suggest you add USED dryer sheets to the tumbler cut into 1" to 1.5" wide strips. It will clean the media and allow it to do a better job.

I use a 50/50 mix of corn cob and crushed walnut shell media.

I use crushed walnut I get from the pet store for the first cleaning, then use corncob with a few drops of Franklin Arsenal polish after depriming to shine. I too use the dryer sheets in teh walnut and in the corncob.

It did. I followed the instructions on the bottle. I guess i should have gone with he 'start low and work your way up' mentality. Where have i heard that before? haha

I like to wet tumble the brass until clean; the run in a vibrator with cob and Nu-finish for about 30 minutes. As mentioned above, the polish makes the resizing easier and retards tarnish a long time.

 

[Dudedog]

When using the dry tumbler and corn cob I really liked the Flitz case polish, seemed to work better that others.

 

[lightman]

I've used the Dillon, NuFinish and several others. They all work. I put a cap full in my Dillon machine with a cap full of mineral spirits and run it long enough to mix everything up before I put the brass in. The finish on the brass last longer than it does with corncob only.

thanks guys. would any normal wax work? I have several bottle of turtle wax. . I went to cabelas for some ammo boxes and was going to grab some walnut and some of their polish and forgot all of it.

Wet tumbling with stainless steel pins will make it like new, if you are that OCD.

I do have it bad I weigh each charge 2 times lol. Check oal 2 times. When I leave for work I have to make sure I shut the door 2 times. Didn't shut all the way 2 times. One time someone was home and caught it and the other cat got out.

If your resizing die has an expander ball, or not, one of the best things you can do is run all your fired cases over a bronze bore brush spinning in an electric drill before decapping and tumbling. The rest of that crud comes out as the cases are tumbled before sizing. That cleans out most of the powder/primer residue and lets expander balls go much smoother out of the case neck as they come out of the die. Case necks will be a little straighter on the case doing this.

thanks ill try that.

Mix 1/4 teaspoon of Lemishine with a quart of hot water. Soak your brass for 45-60 minutes prior to tumbling. Make sure the brass is dry before dumping into the media. Your brass will look great with just the Lemishme but tumble anyway. Tumbling time will be less too.

I get walnut blasting media from harbor freight and use a dab of nu finish

 

[Reloadron]

NuFinish, my brass, my truck and my wife's truck. You could likely use it as a topping for your beanies and weenies.As to the polishes available to add to dry media tumblers? Never saw anything that works as well as NuFinish or similar for less money.

I like using fine walnut because it cleans faster- or so I'm told. People say that corn cob will make the brass brighter. Walnut sure does a good job putting a mirror finish on the brass. The nufinish is certainly worth buying because it shines the brass much faster and brighter than dry media will. it also leaves a protective film to keep the brass looking nice much longer. It also makes sizing the pistol brass a bit easier. These rounds were starting to tarnish a bit from handling so I tumbled them for a couple hours. They are so bright that it is hard to tell if they are nickel cases or brass.

Corncob and polish.
