A Devil Of A Device Ready To Test Next Month

[RM Outback]

Only you know how good it is Jack...keep going. No one else will know until you release it. Keep on upgrading each model as 'Minelab' did.

I still think you're on a winner. :goldpan: :goldpan:

It's released erfect: I got 1 but a bit of hickup due to health related issues with the manufacturer has delayed further deliveries for a short while. I haven't run any dirt through it yet hopefully Thursday all going well.

Cannot wait to see your report RM and best Wishes for a positive result.
Cheers

I bet that shed is to the roof with prototypes :lol:
Will have your own historical museum there after the jackwinder becomes world famous

I wish HH ' but most were used as parts & anything good was grabbed by mates long ago .

Thats probably for the best tokeep the yard in a tidy state. Haha.
Im sure you have it covered with photos and vids anyway, so an online museum would still be possible

This was the inward paddle model , not good enough & years away from todays JackWinder performance plus
I was still so far from discovering the unique feature that's in the present design .

Testing samples when you have found good dirt using the JackWinder .

Just an example for now .

So its dry panning with a windable pan.?

Its a nice concept, but not overly impressed now.....cause Im only 40 and can classify all day and can produce the same amount of cons.

Good job tho, I can see the elderly prospector taking advantage/needing this.

Can see you are not a forward thinker? You too will grow old, will be here before you know it!

No idea whether it's good or bad but you have to realise it's also a hand operated bit if kit for areas where better/faster "power" operated units are banned.

Not necessarily just for elderly prospectors either!
My understanding is you still need to classify the material (& collect it) then use elbow grease to put it thru the jack winder - difficulty would depend on amount of material collected & classified beforehand to be put thru! You could have a very easy day or a good days workout!

The main points for me are it is a workable solution where there's no water & for those of us who prospect in states where mechanical processing of material isn't allowed.
In states like NSW & QLD where a dry blower is out of the equation (unless on a lease) then not only is this a good solution but if used correctly may also be more efficient in fines collection.

It is a great idea, Motorised with some clasification in line would be awesome!

Been thinking about this too as im a lazy carnt sometimes. Was thinking a wire basket the same diameter as the jackwinder opening might not be too hard to rig up. Similar to an earlier version but no fittings to impede the primary function of the jackwinder.
The winding action doesnt look hard at all, so motorising seems un necessary. Its just the classification part that will be the main pita and slowdown of process

Depends on how complicated you want to make it. Shaker screen is cheap and easy. Or just use a mesh panel laying on a 45 angle propped up and shovel onto tarp if you wish.

 

[numpty]

i like it, :Y: :fistpump: :beer: .....thats gotta be better than a dry blower getting dust and **** everywhere..not that i'd really know as i haven't used either.

I do appreciate the positive feedback ' thank you .

There was a comment about fitting a classifier to the JackWinder , I thought the same once , many early prototypes I built had them .

Intense testing went on constantly to find the flaws & improve each model , didn't take more then a year to work out the fitting of classifiers was detrimental in the mission to find the best possible design .

Pre classifying is quick & easy , a half inch mesh is all that's needed ' for better results go to quarter inch .

It's all about the efficiency of getting the most gold for effort !

This is not a mining machine , you sample the best spots first ' then run some 10 kilo buckets of pre sieved material .

After the gold your getting thins out ~ find the next rich spot .

The present JackWinder is capable of retaining almost all the gold in dry material including flour gold !

There are technical specifications regarding slump angles with the shape drop of the eight sided drum & a internal lifter in this latest model that makes it work .

Below is pics of early winders with classifiers

Good explanation Jack.

Do you have any results at hand re: % of gold that is does capture in a standard setting? E.g. is it picking up approx 95% of gold in a standard sample?

Cheers, N.E.

Hi NE ,
That's a heavy question but I'll say the latest design can return 95% of any gold that's run through it - now in saying that the material must be bone dry & the JackWinder would need to be operated correctly .

Imagine someone was going to become a full time small gold prospector , what tools would give them the most consistently of gold returns every week ?

Easy ~ the JackWinder

Thanks for the reply.

Will be interesting to see how RM goes with his in Vic. I reckon the 'bone dry' part will be difficult at times. Certainly for me in N.E. Vic it would be more difficult than the GT. I imagine western NSW, parts of S.A. and much of Queensland/W.A. it would be a ripper.

Best of luck with it :Y:

Thanks Ne ,
I think RM will do well ' he knows the dirt needs to be dry enough for that momentarily liquid action to happen that separates the gold to be trapped .

I did have some good results with old Barry years ago when the dirt was not bone dry , probably lost some in the tailings back then :8 .
See some of the first photos .
