Thread: Vibratory Tumbler Media

It would be interesting to test out some on a worn out junker blade just to see exactly what it would do.

By the way, I take all my pictures with my phone.

Hi Paul, Sorry for the late response, I was traveling this week and didn't have much of a chance to do hobby stuff. I was thinking I'd start with some 1400 grit Aluminum Oxide rock polish my kids already have and see how it did. As suggested I'll use a junker blade to see how it does. It's pretty mild so I might have to experiment some and work up to a more aggressive media but I'd rather work up slowly. Who knows, some of these might produce interesting finishes.

Happy Easter,

Scott

Crushed walnut shells media you can get them at outdoor stores

That was an old thread you dug out

Tumblers work really well for cleaning and polishing

If you look I have a start to finish using Buffers too

The more you ask of the Tumbler, the better the Buffers look, that is just a fact, but the finish from the Tumbler is near flawless

I would like to try the vibratory tumbler. I have not seen the aforementioned thread about buffers but I have one and have used it, still do occasionally, but what I keep coming back to is hand sanding and polishing. As with any machine skill is needed to use them properly. That said it is really easy to round off your grind lines and make the definition look muddy.

For precise, detailed, crisp work I just don't know that there is a substitute for hand work. I would like to find that magic machine or combination of them but as of yet have still not found one.

This does not mean that there is not a place for these machines in the process. I have found the sanding drum attachments for drill or grinder to be very useful in shortening the time in sanding but like other machines great care is needed to keep them from getting away from you.

Love to try that tumbler though.

Should you tape your edge before tumbling?
