Cleaning out a ribbed hose is simple as throwing a rope over a tree branch and hit the hanging, dry hose to knock the heavies into a bucket below. This is useful when you don't need to instantly see your gold

Mate in the past I have hung that type of hose in a tree for a number of months with a plastic bag tied to its end. But the only way to really clean it out is to split it, and that is a bugger of a job. For those who do not know what the difference is between a smooth boar hose and a ribbed hose. In the smooth boar there are no gaps between the ribs, in a ribbed hose there is a gap, and it is that gap which will let in a bit of gold. As a footnote you should only use smooth boar hose as a pick up hose for your pump. It will not let in any air where after some time a ribbed hose will. But that is just my thoughts I may be wrong.

How the hell didn't I see his comment..

Lol anyway, like I said, if you allow it to dry, there's nowhere for it to stick, is the key. It won't work wet or moist and a few hits with a stick drops a fair bit out. Probably not 100% and I'm agreeing to use smooth hose to prevent this issue, but if you had to use ribbed, its still not the end of the world and we can't complain about something that catches gold

being soo cheap, cutting it is a viable option and more an idea then a pain imo. As for on a crevicing device and your wanting close too 100% recovery to your container, ribbed hose wouldn't be of use and yeah..smooth much better.

To get minimal loss through a crevicing pump, the material needs to be sucked up using high pressure through a small diameter, and then deposited directly off to the hose and not have to lift further to get to the hose. This is where the majority of losses occur and the gold falls back down. If there was an inner lip to catch this gold that is cleaned out, you should catch a fair bit more

Been thinking about utilizing a small venturi.
Nipper pump to suck up Only one valve on the venturi to stop any back flow.
I can see a few issues but not as bad as valves jamming due to rocks stuck in them.
If only I had the time.
Still the best I have seen on here is a Hand operated bilge pump mounted on a 20 litre drum.
No sediment at all goes through the pump.

Yeah Tath. That would be a good idea. You would need a skinny hose, not too long, and probably a one-way flapper valve in the first half??

All good food for thought.

Atom that's right. As long as it's a dry sucker. It's still a bit of a pain to rattle the stuff out. That larger diameter stuff you could put a big funnel on the end and feed water/paydirt through like a sluice, but that would be a pain to clean out, for sure.

 

[Tathradj]

Exactly what I have been thinking Tim.
You would still move quite a bit of material with a 3/4 smooth bore hose.

Oh for the good old days of dredging. There are a lot of yarns that can be spun about that pipe, it never gives 100% of your gold back. To chance the topic I think this site need a Tips & Tricks page. Where the older more experienced can post hints and tricks. Just my thoughts. There are some really good hints been posted here hey.

I recon I could easily recover 100% gold from the pipe and any loss is due to user error. I did say "I'm agreeing to use smooth hose" in past post suggestion.

If someone is getting any loss out of a hose.. somethings wrong. How do you get a loss from a sealed tube unless it simply hasn't come out.

 

[Guest]

{unless it simply hasn't come out.} thats it in a nut shell.

 

[AtomRat]

I'm not worried about gold being caught anywhere

 

[Guest]

yep i understand what your saying and agree.

 

[Tathradj]

Back in the good old dredging days it was not uncommon to belt a convoluted pipe after
it had dried out to recover what was trapped in it.
Mainly fine stuff but it all added up.
Especially after you had found a honey hole or crevice full of the stuff.
Main thing was, you were still recovering and retaining the gold in your equipment.
Just had to be aware of what it was stuck in.

Sounds like you done the yards with that kind pipe too. Man its a pain to split hey. They have got some really good stuff out now with a much higher rubber content and much more flexible. {smooth boar of course}
