Cement mixer


Recommended Posts

Depends on how much media you need but if you are buying 50 lbs of media your per pound cost is reduced by 40+ %. There are instructions for building a wet tumbler or "big dawg tumblers" makes great high capacity tumblers and drums.

I use one, just converted over a few weeks ago from a Lyman vibratory and crushed walnut. I bought a small one from Harbor Freight (http://www.harborfreight.com/1-1-4-quarter-cubic-ft-compact-cement-mixer-91907.html) I think with the coupon code it was ~$130.

I purchased 10lbs of media from http://www.stainlesstumblingmedia.com, and I was able to clean ~1,500-2,000 .223 cases at a time. I just cleaned probably about 3k mixed pistol.

Notes*

First I just used Dawn and water, the brass looked great coming out, once it dried, it started to tarnish. I solved this by using Lemi-Shine, the stuff really works...

I use a media separator, if you don't have one, you'll need one to separate the pins. It's not that hard, I use a small bucket/cup to get the brass out of the mixer.

You only need to clean for about an hour. I noticed a difference when I ran for ~30min, dumped the dirty water, and then cleaned for ~30min again with fresh water, dawn, and Lemi-Shine.

Obviously, you need to sort by caliber, where the cases won't get stuck inside one another. I was hoping it wouldn't be an issue, because of the metal blades and the pins...but I was dead wrong! Haha

Overall, I MUCH prefer it to dry-tumbling.

I built some large tumblers for a reloading business that tumbles wet. 15 gallons of brass in each drum, they use and electric winch on a gantry to load and unload them.

This was a dry run while I was putting the first one together.

Spencerhut what size cement mixer do you use?

It's a US made one we got at Home Depot over 10 years ago. I still use it for concrete occasionally as well. It will hold two 90lb bags of concrete, plastic tub, metal blades bolted to the tub. I usually run it for ~2 to 4 hours per batch. Takes a while to sort out all the brass from the walnut after each run.

The best deal on pins I found is on ebay. Just type in stainless steel media pins, they are in Arizona I think. Its about $78 shipped for 10# and comes with a little pack of lemishine.

I bought the small cement mixer On sale plus a 30 % discount with a two year warranty for $150. If your looking to just clean the outside of the brass just use liquid laundry soap and lemi shine. If you want inside and outside get the pins as well. Do not install the paddles when assembling the mixer. I wash 2500 pcs of 5.56 at a time no problems at all. Have cleaned about 40k without any issues.

You don't need to use liquid to clean brass, especially in a cement mixer. The entire process of adding in liquid adds considerable time and a bit of cost to a process that simply does not require it.

Plain old walnut shell from the feed store in 50lb bags along with a small amount of mineral spirits or your favorite brass cleaner (Dillon or Flitz) and toss in a couple of used dryer sheets to cut down on the dust. Simple as that.

The cost of liquid (dawn is real cheap, lemishine if desired is cheap per load and water is really cheap) is less than the cost of the walnut shells, mineral spirits and polish.

I like to wash brass, well before I used stainless steel media tumbling I used to wash my brass in water and dawn in a tub with some hand agitation (pretty high tech). Those results alone were pretty good and one could have easily loaded the brass after that process. Washing the brass is more effective for some of the brass I pick up as a result of the amount of grit, sand and small stones that find its way into the brass.

My drying technique is pretty expensive too, I let the brass air dry...

You are using a cleaning technique intended for benchrest shooting with extensive brass prep investment on pistol brass churned out by the thousands. Are you depriming your pistol brass before you clean it? If you are there is one more brass handling step most people don't have. If you are not de-priming then at some point you will have water contamination in your primer pockets. It's just a matter of time.

Using any liquid cleaning method on pistol brass, or rifle brass for intended for blasting ammo is a complete waste of time and effort. If you have time to burn, knock yourself out, I've got better things to do with my life than fuss over how shiny my brass is.

I have an commercial cement mixer with Poly drum that I use to "dry clean" the brass once I get it from the range, then I sort. Brass is clean enough to go thru any of my presses then I remove the lube and polish on other tumbler using water, Dawn, Lemishine and SS media.

More often than not, I do not deprime before I tumble. This is a batch of 3000 or so cases (after 1hr tumbling in my $50 homemade tumbler) drying in the TX sun in August. In 2.5 beers they were not only dry but you couldn't hold a hand full of them unless you had gloves on.

Who said I was doing just pistol brass? My "brass prep investment", particularly with pistol, is not "extensive" or expensive. No matter what method you use, it takes some effort unless someone else does it for you. I let machines do most of the work for me these days.

You have made your opinion clear, but your comparisons and observations aren't always accurate (cost, time, etc.)
