A friend has lent me a tumbler (he makes his own ammo)
I ran a stainless steel shroud through it - the dinks we’re sort of smoothed out but after a long time it just polished it - I was wanting an almost sand blasted finish- matte
Any ideas or pointers - maybe something I may have around

He has this
Uses it to clean and repolish spent shells
It will bring a spent brass shell case up like new

What medium are you using?
Interesting article here https://adjustingvintagewatches.com/...sted-finishes/. Looks to be getting good results.
Would the material you use for tumbling affect the end result? In a similar manner to surface blasting, using bead, sand etc.

I have one of these which has little steel balls and little steel pins. It is for metal and all it does is burnish the metal, so it is a bit smoother and gives it a very slight shine depending on how the thing you put in was pre finished.
Yours looks like one for polishing gems or rocks I think.
I'm fairly certain you won't be able to get a blasted finish because you are not blasting it. All your medium in there is constantly rubbing against the shroud rather than being blasted and the medium bouncing straight off.
You could sandblast it but I'd try to find somebody that will blast it with ball bearings.
It depends on the media in the tumbler. That looks like the kind of media used for polishing and cleaning cases as you have found out.
There are many types giving different finishes. Also etching in some acids may give a matt finish but obviously great care is required, although some milder solutions like those found in some concrete cleaners can work. Often the finish will depend on the starting finishing as well.

Started out with nothing. Still have most of it left.

Sounds like you need the parts refinished, in which case a tumbler is not suitable they need to be lapped or ground on the appropriate wheel.
Well it does now with a full image. I've only known of similar ones in the jewellery industry.Looks like the Lyman Turbo 1200 for case polishing.
Either way, it's not going to do what he wants.
That’s it - it’s sort of helped the situation as the shroud was very battle scared and sort of flattened that out
I think I’m going to brush the shroud with some garryflex
Thanks all - no anyone need anything polished? 😂
I've tumbled various EDC items made from titanium, steel and brass, etc using the grey tumbling media you can get on ebay. They are like grey stone pyramid shapes and leave the metal stone washed and matte.
