Very interesting, a vid of it running in the works?

71 alum parts have been run thru the machine. I will have to line the ends of the tub as the corners of the parts are getting peended over from bumping against the unlined area.

If anyone is looking for a way to get a faux galvanized finish on alum, pink synthetic plastic rocks is the way to do it .

I'd say these rocks are pretty aggressive. I ran 8 tag brackets at a time for about 30 mins to get the deburr and paint prep I needed. I used a small amount of compound and kept the rocks wet. I believe the time would be reduced if the tumbling action could be improved. The parts and rocks come up from the bottom of the tub in the center and split off to each side. So instead of one big circular action there are 2 small ones. Also, the action is very slow. I'm not sure what change I will make to improve this.

The springs I am using are pretty soft. Load rating of 137 lbs and a rate of 82 lbs. Don't know if adding more would help. The axle is turning about 1000 RPM, increasing this doesn't seem like the answer. Add counterweight maybe?

A couple different things to try that may or may not get your action tumbling:
Run different rate springs on one side. This will get one side of the tub to move more than the other side, which should make it all tumble.
Tie down one side with a ratchet strap. This will have a similar effect.

Or perhaps alter the offset (phase relation) of your opposed weights.

Here's an idea I've been thinking about, but more for polishing tumbler, however it might work with a deburr tumbler... If the motor was to turn and off in a pulsing effect , it will push the media harder on the metal for a few secs or however long it's set (longer for harder metals).

Here's what brought me on to it. Sticking my hand into the corncob tumbler it's light and easy to move around. However once off try this, you hand is forced to push harder to move thru the media. Just a thought

I'd like to see this guy run, but Photobucket wants a password?? Great job, BTW!
