Check out trademe. Get some good motors that would be suitable for $15-$50.
I have this made already for someone who is making their own tumbler ........ make me a good offer .... these bits are stupidly expensive ..... watertight

Hahaha that is EXACTLY what I've made. There's a Chinese guy on Avondale called Tap World or something that sells all the bits for around $50. 150mm push on cap, bit of pipe, and the spin on lid with o-ring. I glued a couple of bits of conduit in mine to act as agitators

Deye223 my motor is on its way. Can you tell me what pillow bearings you used. Please see this selection and see what ones you have used. Thanks. I need the right size to go with your rods too?

Go into your local SAECO Wilson branch and corner one of the staff that looks awake
it's just 12mm rod and bearing but i will be changing to 20mm bearing and 20mm pipe when i get around to it . these are the ones i used and will be using

Deye223 any reason for upgrade to 20mm for the rods? Better turning?
They are hardly going to wear out.. Quite slow + relatively small load = a bloody long time
yeah mate because when it's full and over 40lbs it bows the rods out a fair bit and as pipe is stronger than rod plus the bigger dia thats where i will end up
I've been in the middle of making a tumbler as well.
Gone real simple though. Using a 12V wiper motor and a 10L paint bucket spinning on skateboard wheels. Still got a little to go before it's fully operational, but I have given it a test run to test my ideas and it works fine.
Stainless pins are going to be the most expensive part. Everything else has been free so far.
This tumbler will be great for doing the tons of brass for the AR's.
Test run was using a 7ah spotlight battery. I have now wired in a laptop DC power supply to power the wiper motor. A 3 way switch means I can change direction to wind the bucket on/off. I've also slowed teh speed down a bit. Didn't realise I had it in 2nd gear for test lol.
I like the idea of using some conduit for agitators. Might have to steal that idea :thumbsup:
Here's the test run vid I made.

I've also been making a smaller version using a battery drill motor and old coffee tin to do smaller batches of brass.
Only thing left to do is attach grip tape to the drive rods. Test run with tin full of water worked OK. I have since closed the gap between the ends so the rods don't bend too much.

no thats it all up full of water pins and brass 15lb of that is pins
My motor on the way. Just organising the steel.
Motor arrived from Oz. Steel organised. Start on the minor bits shortly.
Ok so I didn't make my tumbler but I did find the secret ingredient to make cases shine. OK not so secret ingredient of lemi shine is CITRIC ACID. yep that's right. Tried it and look at the results...Attachment 39807
how much did u use and what form did u buy it in
Powder, look on Tar Me. Used about 1 gram, 2 liters of water, approximately 1.5kg of pins with 3 teaspoons of Palmolive, 100 cases. Apparently bad idea to let cases sit in it for too long, it can leach the brass. This only took about 2 hours to tumble.
And I've got single phase 1 HP motors for $70 each + freight
Cheaper to buy in bulk from the likes of Bulk Barn. Supermarkets only have it in 80gram boxes that are a ripoff in price.
Trade Me has listings for 1kg, or more, of citric acid (approx $6-8/kg)
Also helps if you use a squirt of dishwasher rinse aid in the mix ;)
Found this a while back and had to laugh at his efferts to identify what Lemi Shine really consists of.
What’s in Lemi Shine? – UPDATED » Chemistry Blog
I just use Hansells Citric Acid from the supermarket, cheap as.
For my Ultrasonic tank which holds 5 litres water I use 1 teaspoon of Hansells and a couple of squirts of dishwash liquid.
For my SS tumbler, 7 litres water, I use 1/2 teaspoon of Hansells and a couple of overflowing caps of car wash liquid.
For either method you don't need to add much. The big mistake, certainly with the Ultrasonic is adding too much citric acid which attacks the brass alloy.
How long is everyone tumbling with stainless media?
Two to three hours.
Going to try regular auto dishwasher powder (and Palmolive) and see if it does much different. Free sacrificial .223 range brass of course
I've got one of these:
Jewelry Polishing Tools 5kg Capacity Rotary Tumbler Rock Tumbler Polishing Machine Jewelry-in Jewelry Tools & Equipments from Jewelry on Aliexpress.com | Alibaba Group
With 9mm I'll tumble for 1 hour with @150 in the container, fill with water to cover, drop of dish washing liquid and a sprinkle of citric acid powder. Same time for 223 but I do less in one run, prob @60 at a time.
2-3 hours is fine.
2 to 3 hours seems a lot, I think I'd try cleaning primer pockets by conventional methods before tumbling to try save time/power bill.
I wouldn't be doing huge volumes, so wouldn't be a huge head ache.
Does everyone rinse their brass thoroughly after tumbling to stop the citric acid leaving marks/stains on the brass.
Don't get marking with SS process as the amount of citric acid I use is far less than with the ultra sonic process. With ultra sonic I used to do a neutralisation step after the citric acid step where I rinsed the hell out of the cases in a bucket of water with a teaspoon of baking soda added. With SS tumbling again I use less citric acid and the brass gets a good rinse after in water as part of the flushing out the little mongrel pins - but no baking soda. And yes I clean primer pockets b4 tumbling. If you want clean primer pockets as part of SS tumbling that is what takes a lot of extra time.
The other thing I do which may prevent water staining is fairly quickly dry the outside of the brass by rolling them around on an old towel, blow out the inside using compressed air (and check for any stuck pins at the same time) and then they go straight into a food dehydrator.
Well 2-3 hours cleans the pocket out fine for me. They get a quick rinse and then a rinse in meths and a quick dry in the small oven at 120C. They come out just perfect.
I've been thinking about making a rangi separator out of a shopping basket and a chopped off 20l square plastic container. That would complement my current level of rangi-ness, and better still, cost $0.00

Anyone help. Went into Saeco here locally. The dude said the 21/4 pulley was very small.He wants the ratio between the 2 pulleys; the shaft size to run the pulleys ; the belt size and diameter. He also commented the brite steel shaft size of 12mm was tiny and said I needed to go bigger. Is there a special dimension or make of the pulleys because he says there is a standard pulley which has a bushing which avoids any need for matching.Seems tone turning into a major. Told him DYE's project was Aussie made and thought there would be commonality of parts between Oz and Nz.The frame is done so just want to finish the hardware. Thanks.
