I had an order for the cubes of steamed beech 15×15x15mm http://lumberjocks.com/projects/47963. Easy to cut but when sanding started problems began. My wife is sand -of peaks of their fingers. After I post the project I got a suggestion to use a rock tumbler. I liked the idea and I found an old topic http://lumberjocks.com/topics/9848. There’s no machine like that here but it seems that it is relatively easy to make. Remains the question of abrasives. Neither of them out of stock here. It remains only patching with what is available. What to use: steel wool, pieces of paper for sanding, sand for Sand Blasting Machine or something else?

Please write if you have some experience, the idea (even seemingly stupid idea) or you just heard something about it.
Comments are most welcome.

We tumble small pieces of beech in a hinged lid box, that is mounted on a metal lathe,turning at low speed. No abrasive, the sharp edges of the pieces does a very nice job. Try it you will like it. And it does not take very long.

I don’t know if you can get cubes if you tumble. This project was done with a homemade vibratory machine. The pieces are rounded.

Here is the video I was thinking of in my comment to your last post.

It loos like just an improvised cylinder or maybe a large hole saw lined with some sort of sandpaper.
