Yeah, A couple of things.

My wiper motor was getting too hot and I couldn't figure out how to cool it down enough.
The plastic container I was using (A Clear type hard plastic) reacted with the cleaner etc and start producing a blackish stuff.

so

I redesigned the system to allow the wiper motor to drive just a threaded spindle and then added an additional rod 6 inches to the side, mounted in a new ply box for testing, tths was a much better design and worked straight away, BUT, what I hadn't taken into account was that I need to gear the main spindle as it was rotating the whole container around the circumference vs the earlier model which was turning the container at the centre so needed no gearing.

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

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

Whoops, that is correct

Sodium Percarbonate 1kg - Oxygen Bleach | Trade Me

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.
