Burr and matting media for vibratory tumbler to nicefy steel
PekkaNF:
Yes that could be one choice. I have that in my backyard a litle heap left from paving work. We use a lot of under the concrete tiles outside to level harder cruched rock bed. However I would hate to have any of that left into threads or such.
I ordered a 2x5kg set of differetn abrassive pyramids and for polishing ceramic cylinders + little polishing liquid that has antirust properties. All from Germany from a small comppany that is specialized on this sort of products, they don't normally deal with private customers, shiping was 40 EUR, but they definantely seem to know their stuf.

Forgot yo update. Some results here.
First 45 mins and then one hour more tumbling. It does remove burr, but does not change dimenssions any measurable way.
Cut "lip" somewhat smaller and left burr untouched after turning: P8181780c
Same part after one hour of "tumbling": P8181789c
El cheapo small tumbler is ok for mostly small parts I bougt it for. Would be nice, if the bowl would be more donugh shape (it would rotate the parts more and it would be faster to pick them up when they surface). Also would be nice to have quick connect bowls for easy change (different media or material).
One thing I don't know is how much to use this "cutting oil" that bought with it.

Quite taken by this thread, I saw Stefan’s video when he released it and had been looking at tumblers for a while. I finally bite the bullet LOL and ordered a Lyman Pro 1200.

Great. Some peer support :wave: What metal and use you have for it?
I found fairly easy information about case polishing and rock rumbling, but really could not find any HMS level information.
When I used the foam glass, I came to conclusion that it was way too light weight for solid metal objects - looking at tumbler working it would appear that there is a benefit if the parts and aggregate are somewhat of same density.
I bought these:
1: Deburing:

2: Satining:

3: liquid for color metals, testing with steel:

Where I am at now is deburing of steel. Not really done any good experiments with the cutting/polishing/protective liquid part. I hear it has an effect and I can see that debris does not stick to abrasive media when I use is, but amount, dilution, etc. are a big question mark. I am not sure how subtle the effect is.
Half of the reason for shelling out money, was to see if "satining" could be used in lieu of media blasting. I haven't tried it yet.

The above link might be if interest if you haven’t already seen it. My area of interest is in fastener polishing, or satining. Use heatshrink or cable sleeve on the thread as I don’t want those touched. I might also try some masking for marking items by tumbling. The number one use will be for tumbling small 3D prints to reduce/remove the layer lines.
No doubt other uses will pop up as we play :thumbup:
Oh, and thanks for the heads up on matching tumbling media to density of object being tumbled.
