Cool man. Love your thinking out side the box.

Super build pitr lad nice and quiet well done and great info too now you can dredge and still enjoy the peace and quiet of the outdoors without having to listen to a motor running all day take care and happy hunting

Absolutely love your video of your small dredge. Could you possibly send me a picture of all the parts you used as trying to work it out when it is connected is not easy. Thanks

I have just the spot to use that little dredge. I will build one for the wife. Great video. Thanks.

Good video, I always wondered how it would work. This explains how...thanx

Thanks for the video djpitr, this is great! I had an issue with the jet for a minute(Ratio of jet to pipe size wasn't great enough), but after a little research on venturi priciples I had it working in no time. Thanks again for posting!

Thank you. I did learn something. The jet is what I am missing in my design.

Nice job. I like the simplicity of your set up.

awesome brother, respect and power to yours!

great video thanks it helped me understand how the dredge works

Very interesting. Lots of good ideas there.

Nicolas...I got it figured out!!Man does this nozzle suck it up!!Thanks for the great video...After watching about 50 times was able to figure out where I went wrong and correct it.

Thanks djpitr! Great builds!

Nice video, gotta build me one soon! That 3 incher in the back looks like it wants to hit the creek real soon:-)

Those bilge pumps are ok if you design the nozzle properly. The 2,000 pump is enough for the 1.5" pipe and you will need a 3,000 pump for the 2" pump. You will not generate any hi suction without adding a venturi below the suction port. The diameter, position and length of the venturi are most important, as well as the length of the discharge tube. You need to install a vacuum gauge in the suction port so that you can tune up your pump as you develop it without having to use any math. I wish you and everyone that attempts to build one much success!

This video really helped me i had no idea about the jet nozzle . i know now what pushes the dirt through, as u can tell im a beginner your vid really help ...mark from spartanburg s.c.

I would like to watch the next video, with its prototype working. A big hug from your new follower of your KZfaq channel, here from Brazil.

Excellent vid djpitr! I like your ideas here and am going to begin building the same kind of design soon. Going to use a 3700 GPH bilge pump that has a 40mm outlet, (just over 1.5"). Planning on reducing it with a "funnel nozzle" down to 1/2" in the same size "Y" you were using, (1.5"). Hopefully it will give a little more lift than the 1000 gph pump was giving. We'll see. Just using it for cleaning out cracks and depressions in bedrock and maybe sucking material out of the bank and feeding the sluice....who knows... gotta see what the lift will do first. Probably won't "replace" the shovels but will definitely cleanup and get what the shovel misses. Thanx again for letting us see your ideas. Rich.

Thankyou sir for your help I learn something new you have a great day

Putting some research into that project! Keep up the good work.

Cool I have decided to upgrade my pump. Thanks for video.

thanks good video ! i like the quiet Too !

Thank you for this the spray tip jetting water realy will help

your video gave me great ideas

good video, thanks for sharing.. I saw from Lee's video it seemed to work pretty good.

Great video djpitr!

this is perfect and wow....what a great video. i just want to dredge bedrock cracks in a shallow river and ur not allowed to "silt" the river so a battery set up...not to big and 2 to 3 hrs use is what I need.

Very cool, thanks for sharing.

Very good video, thank you for sharing

Dude great video! I’m working on this right now. Been 2 days and I’ve got it not blowing but not sucking really either. Running a 2000 gph pumpwith a 1 1/4 inch hose. From the pump it runs down to 1/2 inch. But still no real suction!!!! Grrr. But good job!

Hi Nicolas!!I got a couple of questions for you on the nozzle build...Do you remember the measurement on your Jet?I just finished building one today using a 2000gph bilge pump but I don't have any suction.my pump outlet is 1 1/8" going into a 1 1/4" hose (8' long) then being reduce to a 3/8" jet in side the 1 1/2" plumbing "Y" using a 1.5" output hose.Do you feel I should go to a smaller hose from the pump to the nozzle or go to a smaller jet (I used the standard 1:4 ratio to find what should have been the proper sized jet.......1.5" :4 = 3/8").Thanks, Terry

nice nice jod man wow very very good Today build one equal to yours like the last one i use one pump 1500 gph this weekend I will try to see how it goes. I really liked you to explain in detail the operation of the pump and the jet. not many people take the time to explain and share why I congratulate you. thanks again I hope you upload more videos of your new jets and experiments so regards from panama central america

Очень хороший обзор, , а я пока хожу с мотопомпой, очень громко орет))) Лайк №389!

Top video bud I’m going try 130 psi 6A 12v pump an useing a compressed air gun as the jet/ nozzle trying to keep the highest pressure at the head of the jet/nozzle hopeing that going to interest the flow an lifting power. (how long is the bump pipe back to your sluice box an it’s max lift height from the pay dirit to top of sluice box ) any help be good thanks an keep it up

isa good vídeo thanks

Excellent!

great job on an informative video Pitr! I'm just starting my build of an electric dredge. I'll be using a 2000gph bilge pump. Not much for pressure but it will move a lot of water. I had wanted to go with a 1.5" nozzle but for simplicity I'll probably end up going to a 2". Sluicelee did a very nice video of your dredge in action and it appeared to have plenty of suction even feeding the long hose. I have a couple of questions about hose length. You mentioned that a shorter hose from the pump to the nozzle would be best but if you shorten it wouldn't you have a problem with pulling the pump around when moving the nozzle? what do you feel is the ideal length? I was going to go with 6'...Do you feel that is too long? also...the hose from the nozzle to the sluice...what have you found to be the maximum length for it? I was thinking 10' Thanks again and keep making videos...they are very helpful!!

nice one mate. Robbo

the jet is from ( Hand Pump ) and you can see it in google images and if your pump is not good enouph to suction you have to use Fenteer 12V Bilgepumpe 3700GPH , it makes you to use 2,5 inch dredge suction :D and if you use this pump on 2 or 1.5 inch suction you have the best suction power in all the world my friend .

If i added 2 (12v)pumps to supply the water do u think it would up the pressure and most importantly the suction?

É um espetáculo de criatividade. Acabo de me inscrever aqui em seu canal . Você tem um vídeo dela na água funcionando ? Quero fazer uma para lavar cascalho aqui em Brasil. Atenciosamente . Joel Rojes .

Why do you connect pipes at a right angle

Cool 😎

Hello, I live in Ecuador and I can not get any of those parts to assemble it, could you sell an already armed please?

thank you thank you thank you i made one

Opps let me try again, the set up you have is good, but there are some flaws your nossal needs to be shorter as the flow is happenig the gravel will wear your nossal out and you will have to replace it reguraly. You have the correct thickness sch 80 fittings is what you have with this nossal you will have a low pressure to a high pressure to a low pressure because your going from 1 inch to 1/4 inch to 1-1/2"this is called a called a ventura fitting which is mostly used in a heating system . You can get it at home depot in the irrigation section which is good for flow i do think you need to build in a way to replace parts that wear out threaded fittings and teflon tape then you don't have to buy everything again because everything was glued just the parts you need to replace barbed fittings and your clamps are good but 2 clamps per joint is best with the head of the clamps at 3 and 9 oclock to get more time on your battary use a solar panel to recharge lol with sunny days if you need help let me know

Use a Y not a T connection.

Why the water returns inside???

I have a question for all the people who try to reinvent the wheel. By the time you buy everything you THINK you need to build something that is already on the market , how much have you actually spent and does it actually work?

Can this be done with an air compressor or does it work better with a water pump?

Nikolas...How's that 2" coming along?Waiting to see the video of it in action!!

setting your batteries on a concrete floor will drain them over time

Díky moc, právě tady maturuju, jestli to udělám ze 40 mm PVC odbočky (45 stupňů) nebo 32 mm. Mám 1100 GPH pumpu, přemýšlím o silnější (3500-3700), ale ty zase chtějí hodně Amp a taky stojí ledvinu. Každopádně pro mě důležitá informace, že to nedostanu moc nad vodu, tj. highbanker musí níž, nebo udělat trubkový splav... Poučná videa, postupně se prokousávám... SUB

You would be able to do a wee video on that 3 inch could u thanks

How mich does this pvc silent dredge weigh?

just a little help my frend you need a 11/2 long radius ty pvc will work better the the y you are using

Sub'd great topic!

end of a caulking tube?

Where did you purchase the hose?

the black tip sprayer is from a seal tube that got cut ;)

can you please get in touch with me I have tried to make one so much as yours but I'm not having a lot of success.

when you are making your 1.5 in dredge you want to change your funnel to one that is 3/8 in in diameter in order to get a better suction I think you are using a larger one and it is not doing what you want it to do

How do I contact you in private?

Please play a video.

to save money on hoses go to your recycling center and get hoses from vacuums' for free instead of spending money for expensive hoses
