I am thinking about using a tumbler media since it’s hard to find walnut shells where I live and paying $50,- shipping for buying online is a bit steep..

I have a bag of walnut shells, but unfortunately it’s a bag with a fine mesh.

I was just wondering if anyone tried alternatives to walnut shells and had succes with it.

I thought chia seeds might be a good alternative (even to mix in with the fine walnut mesh

I looked at the Amazon link.. man, they charge couple hundred $ in shipping to Australia, so that’s not a option.

I searched local pet stores and they don’t seem to sell walnut shells bedding or litter.

No luck.. local welders (steel work shops) do have blasting sand, but that’s obviously not what I’m after.

I guess I just haven’t settle with using my fine ground walnuts and run the tumbler longer..
By this I can get all the rust off, just won’t get the parts coming out looking polished like new.

This is what things look like after tumbling ..
I “polish” it by hand and add a tiny bit of carnauba wax on it for protection

Yep.. I used Brasso metal polish

I also tried mother’s metal polish, much more expensive but I don’t see any difference in the end result
