How long does it last before the batteries need charging? Also what sort of pump? My 3inch ASqualite pump which sure aint light is only 300 gallons per minute with 8HP behind it so 1000 gpm must require a fair bit of push.

Shakeston) Thanks: 3 times Was thanked: 3 time(s) in 3 post(s)		I cant recall the rating, but the Toyota MR2 (circa. 80/90s) had an electric water pump for its radiator system, I recall them being not as pricy as the bilge pumps and able to take more of a thrashing, and of course runs in the 12v range. Could be found at any Toyota car wreckers, bosch make this beastie also http://www.nzperformance...-waterpump/prod_702.html at 115L/min (30gpm/1800gph), it's listed as davies-craige, but should be manufacturer by bosch. Bilge pumps for my application were always a little pricey and aren't generally built to suck with a great deal of resistance (through a thin tube/radiator system or from depth), the bilge pump sits at the lowest point usually, doesn't have to pull the water up or push it through anything with much resistance.

In the short of it it went like this: Made a ally container about 200x200 by about 800 high with a lid on top that could be removed,it was fixed in place with wing nuts,once tightened it sealed itself in place by pulling hard up to a closed cell foam seal. Inside the container was a 12 volt bilge pump that was placed about 100mm from the top. The container was filled with water,lid sealed in place, once power was turned on the pump started to empty the sealed container which caused a vacume within side the container. The sucker tube was around 20mm ID which passed through the lid and down about half way into the container which deposited the fines that you were sucking up. I only used a mid sized bilge pump which had enough power to suck up a 1 grammer with no problems. I dont have a photo but if any one wants some more info let me know. Cheers Steve

The unit worked well,the archilles tendon was that it would suck in air at half a chance,it took a few trial and error goes to sort it out. Great for cleaning out jacked up boulders,logs ect. I have a photo on me external hard drive some were of the setup,just need to find it! take care Steve

And my coputer swallowed the lot before icould post.( I hate that happening.) ANY WAY THINK ABOUT ATTACHING A GARDENING TYPE OF GASOLINE POWERED, BLOWER/VAC TO THE TOP ETC OF STEVES bucket design for some serious crevice sucking power! If you search the Net, and pick and mix, I am sure you will get the idea, and addapt to a plan! http://www.nuggetshooter...ndex.php?showtopic=13011 Cheers---Colin. P.S.Also think about adaptiog a Cheap Plastic WET/DRY vaccuum cleener as yout bucket base, because, the inlet conection the for side intake point has allready been accessed for you, and usually thr plastics better too.

I have never made this sort of contraption whilst I was at my height.( reason, no miniaturization of small engines and attachments then, and they also had a ridiculous price tag ad were still heavy!) The reasoning behind this type of updating of my brain thoughts is that I considered it an innovative solution to a problematic problem of using one item against a half dozen items or so! Weight would hopefully even out approximately? And for the extra manageable suction etc, I thought would sort of rule King. As to noise, if this is just exhaust, Its reasonably controlled by exhausting first into a resonator box, and adding a length of hose, which you submerge in the creek, dam, or wherever it can be submerged. Noise is created by higher speeds, lessened by slower speeds, and controlled by insulation. The reason I first contacted you for a visit was that I had/have a lot of ideas about fossicking/prospecting equipments that should suit todays conditions of operations, and as you already had firsthand experience with the conditions of the work etc, (I saw the fingernails etc.) that I though that you were the ideal guy to pass them by, especially as you were set up to produce some of them if viable?
