Brass tumbling media

[Delfuego]

.

I use 1/8 inch corn cob I get from a feed store with a big squirt of nu-finish car polish added in. 40 lbs runs about $18 and it goes a long way.

I always imagined you would have 4 Thumbler's side by side in your reloading room. This is troubling Hoser

I'm having trouble getting my Dillon case lube off in the tumbler. I don't have mineral spirits in my media, just corncob with some nufinish polish in it. The lube doesn't come off, and instead the small amount of dust in the media just creates a film on the surface of the brass. Had to wipe all the brass down with an alcohol soaked rag to clean it off. I do use a quartered up dryer sheet in every load of brass to help control the dust and keep the media cleaner.

Any ideas as to what the heck I'm doing wrong?

What kind of case lube? I'd try mineral spirits.

I agree its another step to dry, but not much different if you have to check all of the primer pockets for corn, walnut or steel pins. Pins stick in them less often.

Just lay the brass out on a black cotton towel in the sun. (or inside through a window) It will dry.

I have two high speed computer server fans I sit on top of a plastic box, it still takes a while. I'm no rush.

I tumble then deprime, so I never worry about it. Maybe that will change when I start reloading for rifle though.

Dillon, in the spray bottle, shake it spray it wait 5 minutes then size/deprime.

Two big Dillons for corn cob and a RCBS Sidewinder and Frankford for stainless media.

That redeems your image Hoser.

I got part of this from another member on here but.... Do not put brass in an oven but ya know those HF dehydrators???

My process (mileage may vary, do what ya wat to do, etc):
I tumble (of course). I then pour out dirty water until I start to worry about pins coming out. Wife found a little strainer for the drain that is great for catching pins when you push it too far. I then pour the rest of it into one of those plastic sifting pans that looks like a gold sifting pan with holes in the bottom over the separator base. I shake the pan till pins stop "tinking". I then strain all the pins out with a fine strainer. That gets 80% of everything and takes 30 secs. I then run everything through the seperator in two ways. I slowly go back and forth, maybe 2 turns one way and a couple back, to get all the water I can out by moving the cases. I then spin it quickly to use centripetal force to get more water and pins out. I keep doing these two till no more sounds of pins hitting the seperator plastic. I then take the fresh brass and put it on the dehydrator shelves to dry, it is pretty good in an hour. I find if I leave the top cover of the dehydrator on it gets hot enough to melt the plastic shelves so I leave it off. The entire process takes 5-10 minutes depending on how full I made the tumbler. It is more difficult with an overfilled tumbler.

still sounds like a lot of work. 😉

Stick 1,000 in a harbor freight 18 pound tumbler (that's still under warranty),with walnut, add a dash of spirits and polishing compound, leave it on until it annoys you. Separate... Voila!

Seriously... I just use walnut or cob (whatever I come across), cut up a used dryer sheet and let it run for an hour... maybe two if it's new to me brass and filthy. Size / deprime after and the decapping pin knocks out anything stuck in the flash hole. Seems like a whole lot of folks make it a lot more difficult than it needs to be.
