That’s funny ?, your sense of humor eases my pain, for the record anytime you feel like teaching me anything you don’t know I’m all ears??.

Thanks Steve, Actually I had fun doing it, learned a little and came up with a few things new to play with this summer so all was not a loss. I figured the most help I could give someone else headed down the same road was to post my mistakes and possibly save em a buck or two?.

Hmmm, I hate to admit defeat but in case anyone else is headed down this rabbit hole I thought I post my wrap on this project. I’ve tried just about everything I have access to within reason to make a truly useful 12v powered suction nozzle worth the trouble of dragging out into the gold fields and I just can’t get there, close but not really practical. Lift above the water level and bends in the hose line just kill performance and this is pretty much true with every example on YouTube I’ve seen as I followed dozens of other builds. I even built an underwater sluice set-up and the suction into it was... adiquate, so that I could pump gravel, rocks and lead pellets into it and the collection worked perfectly fine, but adiquate suction really needed to be stronger before I’d waste much time using it for real. In total I built 4 different pvc nozzle designs 2 were regular jet nozzles, a 1” discharge and 1 1/2” discharge and two infinity jet nozzles a 1” discharge and a 2” discharge. The last infinity nozzle worked the best and is the largest of the bunch and probably one I’ll keep and test with my little Honda powered 90 gpm gas pump. The infinity jet was bit more trouble to make finding parts at Home Depot That will work is the challenge, I used a number of adaptors and fittings cut and drilled out to make the last infinity nozzle tuneable to the pump pressure and volume. This nozzle has a 1 1/2” intake that discharges into a 2” outlet pipe the nozzle is tuneable from about a 1/16 gap out to infinity (2”) with a sweet spot around a 1/8” gap.providing the best performance with the 12v pumps. Id thought 30 years of moving water around and all the calculations I had to learn that go with it would have helped, but obviously it’s a lot easier when everything is powered bu a 1500 gpm American la France pumper on one end of the hose line instead of a little electric pump trying to overcome the laws of physics. So, anything I missed or something you can see in my last design I can improve on? This is my last build and I think it should work well powered by the Honda pump and have no trouble feeding into my little floating highbanker set-up? infinity jet. View of jet assembly.

I think Fred’s right, I asked my wife and she didn’t recognize the design she’s been in the business for this stuff a long time and can usually spot the brands from a distance, she asked if their were any marks? She said 24K gold like that has been popular in China for a long time it not popular now with the younger generation as much. my only question and it’s not possible to tell from the picture, could it be very old??? That might be important. Taking a second look at the clasp I would not think it to be ancient.

I wanted to test my little setup with some gold Paydirt prior to dragging everything up to the gold fields only to find out its missing gold, so after some research on a end of month sale bought a 5# bag of unsearched no guarantee vulture mine Paydirt for $17 plus $15 in shipping. I’m not a fan of paying for Paydirt but wanted to try it and it seemed like harmless winter fun and hopefully I learn something in the process. After setting everything up and running all the dirt I saved all the tailings for the most important question what am I missing. After cleaning my sluice concentrates I collected .3 gram of flakes and tiny bits and an 8.5 gram copper nugget that must have been tossed into the bag. Most of the gold was caught in the black Matt inside the hopper. I panned the tailings several times and found one tiny tiny fragment of a silver looking bit and possibly a couple of specks of flour gold to small to see without magnification, really I’m not sure they were even gold so I put the retention very high.

Getting around to something more like I had in mind for a finished product I’ve added floats to my highbanker and can now just drop it in water if the conditions allow instead of recirculating water from tubs. One more item to fabricate is a lower header box in place of thr highbanker hopper without the classification screen, I’ll fabricate a short punch plate instead and the header box will lower the suctions discharge closer to the water surface maximizing the suction effect from the nozzle. video flowing water with the 12v 20 amp suction jet nozzle

A new jet nozzle just a bit larger diameter than the last one to better accomidate the bigger Rule 20amp pump I used a 4 to 1 ratio for the jet, the abs is 2” x 1 1/2” fitted with a 1/2” jet made from a Home Depot fuel funnel that is set in 2” abs held in place with automotive auto body filler. The nozzle is 2” straight through the discharge hose with the pick-up nozzle diameter of 1 1/2”. While conducting the time test I held a large gold pan of rocks and gravel under the nozzle and was able to clear the pan in about 10 seconds. I also picked up from Amazon a little battery status meter for $15 just to see how the battery holds up during use and ran 2 tests one with the first smaller nozzle and 13 amp hr pump and a second similar test with the larger nozzle and Rule 20 amp utility pump. I was able to get an hour and 15 minutes out of the 13 amp pump, strangely I got an hour and 35 minutes out of the Rule 20 amp pump very contrary to what I would have thought it would turn out. Both these tests were done using the new JNC950 jump starter that I believe is rated at 35 amp hrs and taken from full charge at around 13v down to 12.06v at a 50% discharge capacity. time test 13 amp hr pump Time test 20 amp hr pump

They make good yard art, if I can find the other parts I will retire my pick?.

If this is posted someplace else sorry for that, just saw this on Facebook. http://hobby-detecting.com/fisher-impulse-aq-a-new-pulse-metal-detector-with-metal-discrimination-2019-novelty-first-photos/?fbclid=IwAR15lD8fs71q2CPmCh8KDJsa_L2XbBs_xbB886Gy5ipRVe0Scgow5jctq54

Lodolite seems to look very similar?

There a some very knowledgeable experts here on all kind of rocks so thought I’d ask if anyone here was familiar with this type of quartz crystal and what the host rock and inclusions might be? In the close up’s the gold color is a bit washed out and pale, but under a loop it’s at least interesting looking and crystalline in structure with a pleasant goldfish color. My wife bought them 10-15 years back although I’m not sure who she got them from she said the quartz came from Brazil, I don’t know anything else on their origin or value. They are cut and polished in a way to magnify the little bit of host rock matrix and little inclusions inside the quartz crystal.

Bathtub test of the two pumps in clean water picking up small bits of lead solder and air rifle pellets using the same suction nozzle. Very little difference between the two tests probable the 1 1/14 discharge is at capacity with the smaller pump running at similar discharge pressure and this is a positive for my test given the smaller pump costs less than half the money and uses 13amps vs 20amps per hour to run. I think it should work even better with the nozzle tip directed into a bedrock crack, Next I’ll take it out to a local creek and see if it works as well sucking dirt and rocks.

I have only one piece of advice, go buy a couple lottery tickets! ??

Wow!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

From the perspective of just a guy just swinging his detector the effect of obsolescence and general market depreciation is a far greater threat to me than risking the warranty on a well engineered adaptation that increases my use and enjoyment. Warranties expire and nothing short of some miracle will get all your money back selling a used machine and if anything we may have missed the boat picking up a good deal on a used 2300 if these coils prove out as it looks, certainly got to be good for the folks that own one now.

I wasn’t really happy with how I setup the pvc and made a few changes that are much better changing how it attached to the box and connected the frame and box as a hinge using only one 1/2 “ repair fitting for the angle adjustment at the header end instead of two. In addition to being easier to use and adjust it all fits easily inside the tub now. It would have been better to use two 90* elbow at the header end of the pvc but I was trying to use stuff I had on hand.

Yep, I think the magnets were a couple bucks more total.

Haaa, good place to be in on the ground floor I won’t forget and will take good care of you’re early commitment as soon as the first royalty check arrives my accountant will be in touch with the documents for your review and signature. New videos for your viewing pleasure soon to be released... “cat with hair ball” and the timeless classic “Feline fains indifference.”

I was cleaning out the shop and came across some extra PVC fittings and a 1/2” thick sheet 16”x9” of a black Corian like material I picked up as scrap from tap plastics a while ago. They claimed it was something special they had for some project and the material was very resistant to things sticking to it? Figured I’d see if it was good for use as a miller table, so I collected the odds and ends I could find cleaning my junk and Home Depot was kind enough to fill in the gaps.tomorrow if I get a chance I’ll run a little dirt through it.

My memory is not so good, cheeper than I thought...

I was wandering Ace hardware the other day and spotted this sexy little heavy duty claw digging tool hanging on the rack priced for around $15 if I remember right. Made of aluminum and really solid with a comfortable handle I JB welded two neodymium bar magnets for searching iron infested signals on the top hopefully out of the way enough to stay in place.

Still expensive, but if the quality is any good and work as claimed one of these might be an option if I really want to run the 20amp pump for anything more than 20 minutes or so? The first one posted is a little over $800 the second battery was listed around $390

Thanks John, added that link to my favorites a lot of useful information there.

John, all the battery stuff is confusing and making my head hurt I’ve been slowly getting the idea about the different calculations and ratings between 120v vs 12v what amp hrs, cranking amps, peak amps and the different issues with discharge rates, the manufactures seem to rely on the confusion. I’m still a little confused about advantages and disadvantages of lithium vs agm I think I read something about lithium while being able to deliver power at a constant 12v evenly through it discharge capacity but that came at sacrifice of lower peak output over long discharge duration to a comparable rated agm deep cycle? And yes can’t believe how crazy expensive they are got to find a source of used cells I can recycle. one of the clubs I belong to has a couple of wet claims out of California I’m sure I can run a battery operated device on, probably better to just take the Honda pump except then it not just going to be the pump and I’ll have to add the utility trailer?

All the bad weather, snow and to many things I need to take care of no chance to get away for a trip to gold country, been watching tons of YouTube gold related videos on prospecting related stuff and the occasional Jeep roll over compilation just to scare me into not doing that stuff with my Jeep on the gold trail?. Lots of ideas on the web for idle hands to foolishly venture, not that I don’t have anything to occupy my time, but a little sucking device somehow seemed like a good idea, so off I go... I’ve been building my little Jeep friendly recirculating sluice and thought I would try making a nozzle for use with the pump I already own, just a few pipe fittings and a little part here and there. I already have a Keene high banker setup and 90gpm Honda pump I can’t use in California, but something small for Jeep travel where it’s ok might come in handy, so I build the first one paying attention to everything I can think of to reduce friction and any head pressure and the little bilge pump was inadequate for the task. searching the web for 12v pumps it’s hard to find anything that produces both volume and pressure at a reasonable price, the rule 4000 utility pump was the most powerful at 66gpm open flow and max lift of approx 30’ with over half its rated volume at 15’, but at a cost of 20amp hrs power consumption, they even made a two stage model rated at 134gpm same rated lift. Only problem the rule evacuator pump line are discontinued and I could only find one seller in the US that still had 3 in stock, every one else was out and the product is no longer listed one the manufacturers web site. I passed on the rule4000 and found a reasonable priced 1000 gph utility pump with a rated max lift of 7m out of Korea and ordered one, it won’t arrive until sometime in April I find out so we’ll see but I suspect it was a waste. I should have stopped reading about water pumps, but didn’t and found another 12v pump that looked better with more volume than my bilge pump or the Korean pump and with a rated max lift of 7m burning only 13amp hr from my battery and ordered it. superior pump came today and I outfitted my nozzle with the new pump along with a water proof power switch and cigarette lighter socket power cord, even with the power of this pump (1/4hp) the suction is inhibited by the discharge restriction and lift enough to make it not quite just enough suction to be practical, however pumping directly into a container without the lift it will suck dirt and gravel more than enough to be worth trying out for bedrock cracks. Everything but the battery weighs 8# total out of the water and in the water it’s slightly negative buoyancy keeps it on the bottom without feeling heavy it also feels fairly well balanced. Before the superior pump arrived eBay kept nagging me about the rule4000 and I still couldn’t find a replacement for this now discontinued pump, so with only the 3 left I figured it was only a couple hundred and I’d might regret it more later if I passed cause I’m on a mission now and pulled the trigger on the rule pump, estimate it arrives on Friday. At over twice the power and capacity of the superior 12v pump it should pump material into my little highbanker if I get a larger battery. Anyway more to come...
