Finally got around to testing my home made SS tumbler with great results. Thought I would post up a whole heap of photos to maybe inspire others. Have most of the parts written down somewhere if someone wants the details.
Was a fun item to make and should make 200 - 300 brass at a time nice and shiny.
SS media was the only item needed to import, not for lack of trying to get locally.
Good on ya nzfubs :thumbsup:
Looks like it engineered to last.
Did you consider buying S/S welding wire and cutting it to length with some side cutters.?
Cheers
Pete
No I hadn't Pete, thanks for the suggestion.Quote:

Is where I got mine from. I doubt it will need replacing for the amount I'll use it but if I need a top up I'll definitely investigate welding wire.
Very smart, I like it
Nice build.
What's the deal with steel media though, isn't it a bit hard on the cases? I can't see an advantage over softer polishing media?
Pick that 9 mil case outta there! :D
According to the media supplier it does not harm your brass in anyway. I'm sure it would after enough tumbles but the brass would need replacing due to use before this would matter.
The advantage against soft media is the SS media is designed to clean primer pockets, flash hole and the internals far better.

That's one site that has some information and is where I got the water mix from.
heavy duty design!
Do the exposed bolt threads and nuts inside mark the brass at all?

Here is my one. It's along similar lines, although a bit more agricultural than yours.
A steel frame and dedicated motor are future mods, I still just use a drill to drive it.

nzfubz could you put up the list of parts, etc. looks like a really interesting project that I may have a go at.

Brass comes up bloody nice, rice lasts about 200rnds with some strips of tissue paper to pick up the residue. Only nuisance is having to tumble it once to polish then about half hour tumble with no media in to vibrate the rice out of the cases. Cleans primer pockets perfectly

Motor, drive elements and steel frame
1/4 or 1/3 Horse power single phase motor. Got mine for $40 off trademe
25mm Box section, need about 2.5m
12mm Solid bar. Best to get all metric or all imperial parts to match pulleys to bar, unlike what I did and had to shave down 1/2 to fit 12mm
12mm Pillow block bearings
8x50mm Bolts, penny washers and nyloc nuts x 8
8x30mm Set screws penny washers and nylocs for the motor
Adjusta feet x 4
12mm ID Heater hose or similar hard wearing hose 1mtr
6x75mm bolt with standard washers and nyloc
6mm bearing for tumbler to run against
1/2 or 12mm pulley for motor
1/2 or 12mm pulley for roller ( there is plenty of info and workings from uncle google on how to work out the rpm)
2mm plate steel for the motor to be mounted to.
PVC Tumbler
6' Marley Stormwater pipe cut off at flared end (handy if you know a drain layer or plumber for this)
6' Marley Flat end cap
6' to 4' Off Set reducer (I tried in vain for ages to find a central reducer but they are not a standard item)
Fernco Qwik Cap 4' with pipe clamp
2' PVC pipe cut in half length ways to act as agitators
CSK Drill bit
CSK SS 5x16mm Socket head set screws with washer and nyloc nuts
Roof and gutter silicone
PVC Pipe cement
Hard 2mmx50mm Rubber strips glued to tumbler exterior
Here are the exerts from my little black book of weird creations that may give you an idea on sizing and other things I have missed from the list.
The timer is the next addition so I can program the 2, 3 or 4 hour tumbles, was $5 off ebay
People also seem to have success making the drive system by stripping down an old inkjet printer and using the internals.
Certainly worth a google.
I would however, question their longevity on a continuous duty cycle.
I've just ripped 2 printers apart for this purpose, so will let you know! Mainly to tidy up parts for restores etc, but will do brass also.
How about an old microwave turntable motor? Or washing machine?
Few on trade me that would suit.

An inkjet example, from memory it was from a metal detector forum or something along those lines.

As you can see I have zero metal working skills. Good thing you don't need them for this project. It's all about the end result
I am trying to decide weather to build or purchase one..

Gunsmithing &Reloading Tools - Frankford Arsenal Stainless Steel Tumbling Media - 5lbs, Brass Case Cleaning
BUT still considering a buid. Very impressed NZFUBZ how much do you think it cost all up?
About $200 from memory not including the media (only have to buy that once) Would all depend on finding a cheap motor.
MMM sounds about right, the bearings and shafts cant be cheap. Thanks for the generous supply of information:thumbsup: I am currently using one of the silly little 3lb ones which just aint big enough so going to do something soon. I will look and see if I can find a motor. Cheers!
Get a front wiper motor and hook it to a bucket. No pulleys or gears. You can run them off a PC power supply too. I've seen those motors for $6.50 on trademe.

That's all you need to know about these little slow moving motors.
D i b: How did you couple the motor shaft to the bottom of the drum (pail) base?
I've been considering making a tumbler along the lines of yours. I already have the wiper motor (left over from another project that didn't proceed) and other electrical bits needed, and some pails and idler wheels. Been pondering over different ways of coupling them up, bearing in mind that the pail must be readily detachable. What worked for you?
Have you considered the Rebel 17, it looks a lot tougher than the Thumlers Model B.Quote:

I tried my favorite go to glue but it failed. I then tried selleys all plastic fix glue. The primer comes with it and it's held so far. I found an old camera mount with a std m8 threaded hole and just glued it to the bottom of the 10L bucket. It's just rolling on 2 sets of rollerblade wheels too. All up that bucket gets fairly heavy eh.Quote:

Interesting, yes it looks better in some respects.Quote:

Yes It looks like a beast. While I could easily weld up the frame getting the parts is a bit of a treasure hunt here in NZ. Just found that my local gardening equipment shop may have pulleys and belts. No cheap suitable motors around that I have found so far.Quote:

Your wiper motor should have plenty of torque and negate the need for pulleys to gear down a higher RPM motor.

Many thanks for the scary terry link @Dead is better ,
I have been using this 12volt 5amp supply for a couple days now with no problems. https://nicegear.co.nz/electronics-g...-power-supply/
It came with a US plug, which would have saved buying the suggested NZ/AUST figure 8 plug, I would have been happy using an adapter and saved the extra $5. Very prompt service though.
The old wiper motor I'm using is slow but quite functional. As it was a perk, I'll put up with it for the time being before deciding whether to replace it or gear up the drive RPM up with pulleys.
I'm picking it is missing the high speed setting of a more modern unit.
Thanks for the info. So you have to unscrew the drum from the motor?Quote:
