Question for those who have made a tumbler:
Does a regular bucket with lid work, or do you need to glue some sort of "paddles" to the inside to ensure the brass actually "tumbles" rather than just sliding around and staying at the lowest point. Visualise the inside of a clothes dryer.
Some commercial case tumblers are hexagonal, so the brass travels up the side then tumbles back down during rotation.
From the looks of things we will probably need to glue in a few paddles.
I use one of these , have a nice shape inside that tumble the brass well, good screw top lid and can get them from local recycling centres for next to nothing

specweapon:
I don't know of any recycling centres near where I live, so to help me locate such containers could you please tell me what these containers are made for, what size they are, and what they are called?
Thanks in advance
I made ine from a 1ltr Coffee tin and glued/riveted some paddles to agitate the brass.Quote:

Sorted...Mazda power! Wood base used as a mock up for sizing. Metal frame to come.
Works a treat.

How much current does your wiper motor pull? Any ideas?
Keen to have a go at this
Not sure. I'm thinking of making another on out of an old multi function printer as well
Very clever thinking. Awesome.Quote:

Not sure how easy or otherwise it would be to attach paddles inside them with water-tight fastenings. (I'm looking at making a 'wet' tumbler) But I'll keep them in mind.
Sad news, I have succumbed to an off the shelf 5kg tumber :D :D
150mm PVC pipe, capped one end, screw cap on the other. PVC cement a couple of lengths of conduit (PVC conduit of course) on the inside to help the contents tumble, rather than slide. Watertight, works a treatQuote:

..and a 150mm 'push on' cap from the same place. I have a length of plain 150mm pipe ( to go between the fittings, only need 80mm so not worth buying a meter..), and a meter of the conduit you can pinch if you're in Auckland. PVC cement from the Warehouse is a couple of bucks.
Total cost around $50 and it's bullet proof.
good man , you will love it , and it works like a treatQuote:

Anyways, I could have fixed it and added a gear to the motor and the spindle, BUT I was getting into all sorts of other stuff and thought bugger it I'll spend my time on something else (Like getting the wife to the pistol range and agreeing to joining the AK pistol club!!!), which incidentally went well..good on her :thumbsup:
All in all, its all good.
Link to said 5kg tumbler??
What do you guys use as a water softener?
I see you can get that lemishine off fishpond which is what all the yanks seem to use.
Do you need it or can you just use baking soda or similar.

The citric is there to makes your brass shinier

Would that do it?
I was lucky enough to be given a container of Lemishine, this and the citric acid was my plan for when I ran out..
lemi-shine aswell, i picked up a couple when i was last in the US,
will grab a couple next time i'm there
I use about a 45acp case of lemshine/citric acid to 400 odd 223 , or 700 odd 9mm , in my tumbler , stainless steel pins , tumble for 1 hour on number 2 setting , (same tumbler as pictured ) works great
whoops , and a squirt of dishwashing liquid
I only know what I have read about stainless steel pin tumbling and understand that lemishine is used a water softener and to allow the dish washing soap to work better and keep out calcium etc?
So we must have the equivalent to lemishine in NZ as we have dishwashers?
Also they (yanks) seem to tumble for 3-4 hours.
I only plan to do it once every 4-5 firings on pistol brass and once every couple on my AR brass.
I may have got to small of a tumbler it's only a 3kg one so i assume I will only be able to do a days worth of shooting at a time but that's all I intended.

I don't bother with Lemishine, perfectly happy with the end result.
I use a squirt of dishwashing liquid and under a teaspoon of plain old citric acid u buy from supermarket and hot water tumblr for about a hour and have no problem at all I rinse fresh warm water over the cases in the tumbler till it is pretty much clear with no bubbles I dry in a dehydrator in about 15mins
I have seen Lemishine in 2 local shops recently. just haven't bothered to buy it as I have always had perfect results just using Hansells Citric Acid.
What’s in Lemi Shine? – UPDATED » Chemistry Blog
Same recipe, using citric acid from supermarket. Works a treat and no probs.Quote:

So the S.S media can only be sourced via gun works etc? Is there anything else that will work?
