    With the my dry washer I just turn it on and reinsert the tray. Once reinserted And blower on i throw in some of the material I've already ran to get the air pressure back in sync. I was told when reinserting the tray it should hover over the Recover box. Doing this it blows out any rocks in the crevices I usually don't worry about the material under the fan, but I know there is the potential for there to be gold there. I used to but never found any gold, I'm sure some of u guys have your own take on this however.

    Would you recommend leveling at least the hopper before you start so its close to level or is the sluice box more important to level before you start.

    Leveling the hopper or the box will give you a starting point, but the true indication is how the dirt and rock is flowing out of the box. You want a nice even flow across the entire width of the box. Adjust the entire DW side to side to arrive at an even flow. Do not worry whether the hopper or box is level using a level. It's all about looking at the flow out the end of the box. Also you want the box angled downward at about 15 degrees and enough air speed to get the dirt and rocks flowing. To much air speed and you blow gold out.

    Thanks for the information. I did what you said and I was able to get nice even flow over the sluice box. Now I just need to find a good spot to work on my claim before I have to head back to home to the cold Midwest. Any tips on where to look on a desert wash? The wash I am working is cut through a mountain. We are finding gold but always looking for a better spot.

    Not sure I could be much help cause I have no clue where your at, your area, etc. I would sample as much as you can then work your best areas that gave you the best recovery.

    to get extended life out of your engine try to keep it out of the dust coming from the dw. you may have to move it many times during a run.

    Reading back thru this thread I just realized I never mentioned that I did get to spend a day Drywashing on the bench placer I had hoped to hit.

    A friend and I ran 7 16 gallon samples from various spots in the area. Each set of cons was panned separately. We found at least a little gold in every sample and two samples were clearly better...spots to hit next summer!

    PS we got a heavy rain that night so it was the end of Drywashing season...

    Great Thread!!

    I've been thinking of a dry washer now for some time.
    The family does a lot of camping in Mojave during the winter. And with the drought, everything is plenty dry.

    So this is nice info to keep in mind when looking at DW's.

    Is there nothing else out there for processing dry material?
    Is the current Dry Washer system basically the same it has been with no major changes?
    Just curious. As I look at them with the noise and dust, I think "there's got to be a better way"..

    Any way, great thread and will check up on this often.

    I say the same thing. there has to be a better way. dw systems really haven't changed much for years.
    their are basically two types, puffers or blower type, both work well.
    dry washers are perfect for dry climates where water is hard to come by or to expensive to haul to the prospecting site.

    Well,

    I was able to find an old Keene 151 for sale.
    It's got to be from the 80's as it has no adjustable flow gate in the Hopper.
    No Fan with Vibration bar and the riffles and tray look shot.

    I got it for $150 so for the Stand, nice Aluminum hopper and a recovery box that is open for changes, I figure It was worth that.
    It's going to be my Frankenstein DW of sorts. I like some of the ideas I have read here.

    First, I want to ad a Vibration device to the lower box, but have it spinning in a vertical path vs. horizontal.
    Maybe even two motor's in sync, but I think 1 should suffice.

    Second, I want to try and dissipate Air better through out the lower box.
    Maybe some light weight styrene plumbing to distribute and get a nice even flow of air through out the whole tray system.

    The Riffle system I think can be better too.
    I've read that DW's rely on a static charge to help capture the gold.
    So I was thinking using 1/8" Polyethylene sheet and create a new Riffle system.
    Maybe increasing the amount of riffles but alternating sizes as it goes down.
    Maybe adding a little "cup" as it were to the riffles to help capture the shiny.

    Also regarding Static, I was thinking about how can MORE static charge be created?
    Maybe adding a little Electrical device (capacitor?) that is ran by a 9V battery, that increases the static charge to the Riffle tray itself?

    Has anyone used springs between the upper and lower box?
    It might allow the lower box to move a little more freely.

    Maybe a Metal detection device (Bar) in the Hopper where larger stuff runs off?
    A signal goes of if a big nugget goes by that was too big to go down the sluice.
    Heck one at your tailing end too.

    Boy for that matter, your riffles could have a small detection system and an LED goes of on that particular riffle that caught some gold.
    Wouldn't take much to do that really...Sorry, just thinking outside the Box I guess.

    Anyway,
    I was excited to get this and wanted to share.
    Looking forward to bringing this thing alive.
    All suggestions will be GREATLY appreciated.

    Cheers
