BYW I haven't seen this device other than the pictures attached.

Looks to be the keene A52 sluice.

I agree. Looks like A52. As for repair, some aluminum and a good sheet metal brake. Needs to be tight though.
I don't see any reason you can't get'er up and running in no time. I would not try to hammer it out because aluminum
is to pliable and will stretch. Good luck Bud!

 

[DizzyDigger]

I agree with the So. Gent, above, but lacking a metal brake I would
have a go at it with a rubber mallet, couple 2x4's and 4 C-clamps.
Might take a few minutes, but it's most definitely worth doing.

I would first try to carefully fix it. You have nothing to loose. If that does not work, then try to bend new metal.

I agree it is an A52 but the flare isn't for it. It looks to be a customized flare. It is longer and wider than anything Keene sells for the A52 or the A51. Take it to a metal shop to have it repaired. Well worth it.

Good Luck!

That's what I thought when I saw the flare too, it just looked a little bigger than standard. Any disadvantage to the bigger flare?

 

[2cmorau]

ive seen worst, nothing wrong with it, run with it, but if looks matter use a block of wood and rubber mallet

I was able to get the bottom to true, thus able to get the riffles to go back in, now we just need to clean it up and take it to the river.

I've never used an A52 before, but have run a few river sluices...do I remember hearing when this box is running right the water creates a V up top followed by X water pattern between the riffles.

 

[KevinInColorado]

Yup. And for really fine gold, keep the water depth shallow in the sluice.

 

[425jesse]

Like just deep enough to keep the riffles submerged?

 

[425jesse]

How is the A52 for fine gold recovery? -12 to -100?

 

[B H Prospector]

I find -100 in my A52 every time I use it. The larger flare will only be helpful with water volume. Alot of miners will build wing dams to get what the larger flare will give you. Glad you got it fixed.

Good Luck!

Gotta agree with BHP on the 100% recovery. You really can't improve too much on the A52 and if there is gold there you will find it. Nothing like a little history to go along with your sluice and that baby has some history now. Good luck.

Thoughts on how many GPH is about right for an A52?

 

[team sidewinder]

Well a old prospector told me if you are running a Keene power sluice conversion on the A52 that a 400pgh pump is enough but I personally am going to run at least a 1600gph pump on mine when I get it. Seems to me 400gph is on the really light side as far as a pump flow goes.

i bought a pump for my keene A52 and the guy at golden detectors in colorado told me that it needed to be 2200gph. the pump i bought has a restrictor that brings it down to 1600gph.

How does the 1600gph work for ya?

 

[tweeta_bear]

i have to run it at 2200 in order to get the material to go through the sluice. i also put a ball value inline so i could control it.
