Rock and Mineral Forum Guidelines

There are just a few rules here and yup I do enforce them and keep an eye on things as best I can. Here are a few guidelines I'd like you to follow if you will be participating here. This forum is not moderated as heavily as the other sections so please do not enter or open a topic if you think you will be offended. If you are at least respond like an adult or we will remove your post as soon as brought to our attention.

Vulgar and abusive language is not welcome here! Heck a cuss word to get a point across is not so bad, but I think you know what I mean.

I will not host public arguments and pissing matches between individuals here so please just don't do it. When it happens the post most times will simply vanish into cyber space.

Political or Religious posts belong in "Off Topic" but surly you can find other forums that host those discussions if it is your thing, I don't think anyone cares if you are Conservative or Liberal when we are out hunting gold nuggets.

You may not use this forum to advertise any other dealer, store, or product without written permission by owner at any time. Used items are allowed in the classified section.

This forum is not responsible for anything said by it's members at any time. This is a public forum and will remain so and although I can and will occasionally zap "bad content" I don't do it often and so far have never permanently banned a person. Also opinions expressed here do not always represent the opinion of the forum's owner!

Guests are welcome to browse the forum and use the information provided by registered members, but you can not post yourself until you are a registered member.

That is pretty much it my fellow Nugget Shooters so enjoy the forum, keep it clean and play nice.

    • Ahh yes, there is always that possibility, slim but still possible I suppose ......  Nothing like exploring all the possibilities tho...
    • Thanks, Bob. The actual concept occurred to me last August, but I'd been working on dry gem recovery for about 8 years, building 8 or 10 different designs. As it turns out, you can't recover gems dry. A physics phenomenon called "Granular Convection" aka "the Brazil Nut Effect, prevents it. So I built this for that purpose (not being aware of GC), and when it didn't work for gems I tried it for gold, and it worked great. A few bugs to work out, and it's now a pretty nice little wet/dry gold machine that can be built in almost any size. I sell the 18" unit for $550 + shipping, with a solid body of HDPE corrugated pipe. That model weighs 19lbs. The one I use myself is a skeletonized version that sells for $650 + shipping. It only weighs 11lbs. I'm amazed myself at how well these perform.  They only draw about 1 amp, so can get by with a fairly small battery pack, and when used wet, they require very little water...just enough to keep the material on the diaphragm sort of soupy. Water has no impact on the recovery...that's all in the mechanical action.
    • Bill's Youtube site is really great, both for newbies and us guys who have been up and down some washes and ridges for a while!  Check 'em out!  Cheers, Unc
