Anyone have any experience with vibradry? Looking for some advice and input. I see vibradry and vibradry plus listed in ads. It looks like the plus uses stainless steel shot in addition to the vibradry?
Thanks in advance Chuck

I've wondered about this too. How is it different than corn cob with grit? Why is it so expensive? In what situations is it better than traditional wet tumbling?

I think I may have actually found something jamesp has not tried already. Chuck

I have actually pursued this in the past and wound up doing a DIY with it.It was my feeling that they were using ALO for the polih and corn cob for the media. I searched the web anad finally came up with this type of product I came up with this company and found out they make all kinds of slurry's, emulsions, colloids etc.They use diamond, ALO etc. the first I bought was an emulsion 3 microns IIRC spread corn cob media out flat and thin enough to fill a 3# raytech vib bowl with then used a spray bottle and saturated the media.To my surprize it almost doubled when it was absorbed. I let it dry for a few days before trying it. The product actually was kind of oily/sticky feeling, I dumped about 40 peformed pre polished cabs to about 600 if IIRC. I was impressed with the results, they action in the vib was impressive to say the least and the polish was great. I'm sorry I don't have any pics of the process, and just after that I got caught up in a new hobby (machining) and it has been taxing my learning curve and pocket book LOL!

I am running a dry tumble right now with the corn cob. This vibradry has me intrigued I was just hoping for a little input before dropping that kind of money down on a test. The dry method works good on petoskey stones but those are a pretty consistent hardness. My goal is to minimize undercutting on varied hardness materials. Chuck

Jugglerguy jamespI called and talked to Don at diamond pacific today about Vibradry. He helped me out a bit. The biggest thing to come out the conversation was the fact that there is zero grit break down. This means the rocks go into 600 and come out at 600 unlike a wet grind where the rocks go in to 600 grit for a few days and the grit breaks down to 1200 or smaller. This means that to use this process would require more steps, more time, and at $26 per pound a lot more money. His recommendation for what I am trying to do was to get to around a 1000 grit finish with the wet method or corn cob dry method then switch to vibradry for 3000,14000,50,000. The other info I got was that the one pound quantity is the correct amount to use for the mini-sonic 4T 4 pound hopper so I figure it should be just about right in the loto too. Chuck

Now I'm really intrigued. I have a lot more questions too. I wonder if my corn cob media breaks down. I keep adding a little more aluminum oxide to recharge it. If it's not breaking down, why am I able to skip 1000 grit that I never skip otherwise? Maybe I shouldn't be skipping it.
$26 a pound isn't bad at all if it lasts indefinitely. Of course, it's going to have rock dust in it after the first use. I would think the rock dust would be a similar size as the aluminum oxide and that it would be softer so it shouldn't be an issue.
Did Don say how long you should run each stage?

Did Don say how long you should run each stage? I forgot to ask about how long to run it. It was easy enough to call and he was more then willing to talk about it. He said he uses the 50,000 on all of his cabs after they come off the genie and it always improves them. I am less confident now that it will do what I am looking for but now I really want to try the 25,000 and 50,000 on a batch of rocks after running them through my normal process. Chuck

You guys come up with the most interesting things. Hopefully Drummond Island Rocks will have a chance to test out the vibradry and post results. I'm very interested since I would like to try tumbling some softer stones.

Any new info on VibraDry+? Would like to try it out but trying to get more info. The Alum. Oxide I currently use is leaving a residue on any little imperfection that is hard to remove!

Chuck Always wondered about dry tumbling NOT breaking down abrasive because of the lightweight protective dry 'slurry'. Makes PERFECT sense that it would not break down abrasive requiring multiple steps. But you guys know my theory, sticky, heavy clay slurry in the rotary and sticky, heavy sugar(or Borax) slurry in the vibe. Suck them rocks together with sticky liquid cohesive forces to crush that abrasive as the tumblers roll or shake.

Has anyone tried using this machine wet?
