Sieve alternatives for beginners
« on: April 08, 2009, 12:36:25 PM »
A new set of sieves are a potentially expensive but necessary option for beginners and others who just want to 'have a go' at fossicking.  What I've found to be a handy alternative is the bait sieves they sell in fishing tackle shops. 

They are only about $10 to $15 (I get mine from BCF and they are an Alvey brand - the company that makes tough fishing reels too) and have a sieve screen with 5mm holes.  You might think they won't last but I have three that I have used heavily for over 3 years with no signs of cracking or damage.  They can be handled fairly roughly so they are great for kids or for throwing in the back of the trayback.

In North West Qld where I do my fossicking I use three at once to do an initial sort of material. I find them particularly useful for semi-precious garnet and amethyst.  By the way, I also use the sieve from an old water tank and find it equally useful.   

Attached is an image of a sieve with some garnet rough.  (This rough was heavily fractured ... a shame as I'd collected about 20kg of the stuff before I did a little washing to see if it was any good).

Cheers,
Fullerton

Funny you should mention Sieve alternatives.

My first fossicking expedition was with a saucepan steamer, a colander and a bag-a-beaut!

I have done nearly 2 pallets of bag-a-beaut and pulled out some pretty spectacular stones. (Albiet with proper sieves).

I have spent days and days camping and digging around Inverell/GI, and nothing I have found has compared to some of my Bag finds.

I have had trouble trying to get a large metal seive that is strong enough to handle the amount of wash I put through hit. The hardiest cheap alternative I found were soil seives from bunnings. They do have a metal seive but I have worn out two already. Does anyone know where I can buy a decent sized 1/4 inch seive that will last? The typical gem sieves are too small (40cm or so in diameter),

Cheers, Cain :)

Miners Den have 17" sieves (aluminium) in 1/16" and 3/16" mesh but they're a bit pricey (IMHO) at almost $70 each.  More choice in mesh size in the 14" size.

We've had trouble finding supplier of sieves.  We get 33cm version (14") but have not been successful in sourcing the larger or smaller ones (we get enquiry for them so still looking).

The shops here all have the larger sieves here in 4-5 sizes (1/16 -1/2).

They are getting up around the $100 mark though.

I use them when fossicking and can safely put a 15 litre bucket of wash in them without a problem.

I will find out their distributor for you.

Hi Bluey
When you say here, where is that exactly. I have been trying to get some larger sieves for a while without much luck. 17 inch I'm talking about.
Thanks

 We have stuck to the 33cm Sieves,any of the larger ones (apart from the old timber frame ones ) we have tried just are not strong enough to last.
 Fullerton makes a good point for beginners,the Plastic sieves are a real option for a weekend adventure. Other then the Fishing Shops almost all the Hardware Shops stock these often as Rainwater strainers.
Cheers Andrew

I have not used proper sieves all year, which reflects in my finds. but then I reckon Stix would swap me gear if he lived down here. At the moment I've got a approx 10mm colander and 1.5mm strainer but mostly I speck old workings. which one needs very little gear at all to do.

CQ Gemfields Claude.

I was told yesterday that the shopkeepers get their sieves for a George Pennini in Sydney. I couldn't get a phone number out of them.

He does make quite a strong sieve in 13", 17" and 20".

Might help,

Well my sieves must be broken, they don't find sapphires :(

Out of interest:
 I spoke with Jorge Pennini this morning and he sent me his current prices .

Not sure if he will sell small lots to the public or not,he did not offer me any discount as a Dealer.
I cannot buy and resell from him as the 13"/33cm sets would need to retail at or above $100 (our current retail $60 per set)

His Ph 0295707911

Hi everyone
Ok, I have just bought two 17 " sieves (6mm & 12mm) for $67 each from the miners den. As you said, Andrew a bit pricey but still a bit cheaper than a Penninni original, plus I was getting sick of looking and my trips coming up in three weeks.
Thank you all, I got some great info. Might try making a throw sieve as well if I can find some 6mm welded or woven mesh.
