The results using stainless steel media always impressed me; however, being accustom to the large batches my big Dillon tumbler can turn out the idea of only being able to 2 lbs of brass (only 230 rounds of 9mm) at a time just wouldn’t be worth it.

The Thumler’s tumbler despite costing almost $200 is only good for 15 lbs . Once you add 8 lbs (a gallon) of water and 5 lbs of SS media that only leaves 2 lbs of brass. You can also get a 40 lb tumbler as well but at almost $700...well if I wanted to burn money I would just buy new brass.

I started out ebaying parts, a 1/3hp 40 rpm gear motor ran $30, 1” pillow block bearings (1500lb load rating) for $8 and a Lovejoy coupling for another $10. I then made a frame out of ¾” to mount the motor and bearing box. Cut a disk out of 3/8” steel and mounted a 100 lb (12.2 gallon) bucket used to hold chlorine onto the disk using 10-32 bolts. I slid another bucket into the first one and cut slots into the outer bucket so the inner bucket would inner lock with it. I then cut 4 ribs 1 5/8” tall out of ½” thick plastic and bolted them in to the inner bucket, using 10-32 counter sink bolts, every 90 degrees to agitate the brass and media.

The media is pretty expensive at $25 for five pounds so I only bought 10 pounds for initial testing, so if it didn’t work I wouldn’t be out of too much money. So I started out with only a gallon Ziploc bag of .223 and a few hand full’s of 458socom for the trial run.

The mix was 2 gallons of water, 2 table spoons of Dawn dish washing soap, ½ teaspoon of Lemishine detergent. Even at over twice the capacity of the Thumler’s B model there is still a lot of room for more.

I ran the mix for 1 hour and separated the media/brass using my Dillon separator, rinsed the brass with clean water and dumped it onto a screen I built for drying dip lubed bullets. It was kind of cool today so I set a heated fan up to help dry them out. In about 15 min they were all dry.

It’s not much to look at but once I get a few more bags of media I figure it will tumble around 4500-5000 9mm cases at a time and I will have under $180 invested including the 20 lbs of media.

Can't believe this kind of home brewed tech didn't get more attention...neat idea. Any leakage issues where you attached the agitators onto the inner bucket? I've been getting 2-300lbs of once fired at a time from a friend and using a small vibratory cleaner with walnut is getting old

Hey, sirch!

I made one from an old dryer that ran 5 gal buckets. Was all free !

I did close to 1000 rds of 9mm at once in some walnut shells, took less than 2 hours to be ready to reload.

I built multiple buckets and set it up so I could quickly swap out buckets and keep running.

When used in an ultrasonic it makes used brass look new inside and out.

But it has to be used wet, and you have to dry the brass, and it basically looks like a big pain in the ass to me.
