Only a portion of my PVC nozzel build. Entire video will be posted when complete.
This is absolutely fantastic!! I met guy up in Maine working the river with your prototype. It worked flawlessly!!!! I will be building one tomorrow. Thanks for the insight🤘⚒️
Really useful especially in our place where ready to use nozzles are rarer than gold. Thank you!
This is the BEST EXPLANATION of a dredge I have seen on utube. You are a star. Are you using a 12v pump or gasoline?
5.5 hp gasoline.
@@randallmonville2310 thanks very much indeed. 😁
This is so wrong the pressure water has to be introduced immediately after the suction side of nozzle or pressure water will be pushed out of the suction side. I am a mechanical engineer and your design goes against physics sorry😢
The pressure water goes over the suction nozzle creating the suction. If you extend the pressure nozzle past the suction inlet it will jam with rocks. You can see it working at the beginning of the video.
Where's the venturi? 🤔
Its the part made with the bondo.
Parabéns ! Gostei muito . Tenho uma saída da motobomba de pressão a gasolina de 2" polegadas ,,,, esta pasta que você coloca é uma cola ? E onde posso encontrar para comprar ? Obrigado desde já . Parabéns pelo talento e a forma clara de explicar .Att.
Bondo is an autobody filler. Its used to repair dents on car bodies. You should be able to buy it at any auto parts store.
@@randallmonville2310 Entendido. Meus cumprimentos ! Obrigado me ajudou muito. Sucesso para você , em tudo que faz , fez e irá fazer. Att. Joel Rojes. direto de Brasil.
I'm not sure this is very cost effective considering time and material when you can buy a steel nozzle for $100. But this is an excellent video for the diy guys.
I am dredging a hole in my boat slip and saw your video and said this may work. My question I am curious about is that if I use a 4 or 5 foot gravel (in my case sand)suction pipe would that affect the performance? I need to move about 3 yards of sand for my keel to rest in. Thanks for share your video.
It will. But it may take a bit of time. You can extend the end of the nozzle. Try it.
I'm in (or under) the same boat. Did you have success?
Ficou muito bom o seu projeto.E melhor ainde o tipo de sua motobomba acoplada no mangoti.👍👍
Great idea, but bondo absorbs water. Use a fibreglass reinforced filler instead
That is a hella cheap way to make a 3inch dredge. The regular would easily be a couple if thosand. This is a vest a couple if hundred and the quality is the same, maybe better
Хорошо придумано. Спасибо
muy Bueno......gracias!!!!!!!!!!!!!!!!!!!!!
Looks great... I wanna make one myself
Would I need to make some diameter adjustments if I wanted to use a 3000gph 12v bilge pump?
I doubt it would make enough pressure to create a good suction. All you can do is try though. Start at .5 dia and increase .125 till you get suction.
That has alot of suction. You really seem to know what your doing. I am currently attempting to build a 4 inch nozzle in order to suck sand off a lake bed and pump it behind a new seawall for backfill. I am attempting to pump the sand up to 6' in height. So far I have been able to pump sand but not enough. I dont have good suction. I am running a riverside 2-1\2" high pressure pump powered by an 11hp honda engine. What should my jet size be for my 4 inch system? Do you have any suggestions?
I need to do the same thing and my design incorporates a second pump further up the discharge line, which will act as a booster.
,hi Randal,,will a 50 cc honda work,,my keen nozzle scree up,nice work
50 cc is small. I don't think it will work. Try it though. It may be ok.
the best friend at the putty are a thinner with clothes ....hihihihhi not yours finger ...hhiihihihi
and for agent de démoulage take soap for a kitchen.... palmolivei have a friend we know do thatttt is a nice twisttt try thist jim....
for a ultimate aderance with a pvc pipe wash interior pipe witch thinner and after sand 180 ans re wash take a carton for mix and stay in your box tool for a next time is more gravely ...sanding... more batch more sanding he falling love in a body shop i work ... sorry for my english im stay in quebec city.......and for your bubble take a old electric sanding put your piece witchputty wen on in a pad the vibration make a job see a next tine ....jim ...famille jim594 at g mail
well its nice use of my principle :) that i use in my nozzle i made :)
Nice work. But how many hp is of your motor pump? Can I do dredging of a pond with 2 hp motor and this nozzle? If not what should be the min capacity?
Great idea!
Nice build I couldn't do it better myself :)
REDMAN PROSPECTING thank you.
Randall Monville yup happy prospecting
+Randall Monville hi I'm also macing a dredge nozel but want to cnow what size nozel works best to create the vacume .any advice pleas
Christiaan Schlechter start with .5 inch. Will depend on pump pressure and hose length and diameter of dredge. You can drill it out to make it bigger.
Nice idea Thanks for sharing, sO the size of the inner hole is 1/2 inch correct?
any digestions on nozel size need help pleas
The "u" piece is to get the high pressure water to the jet.
Enjoyed the vid, does the "u" piece serve any purpose?
I also have a 2" semi trash 9000gph pump. But I was planning on going 1.5". I have hoses and everything else 1.5". I say it should work since it has a smaller diameter hose?
The Caribbean Digger should work with 1.5" PVC. just make the nozzle a touch smaller, say .375".
Randall Monville u mean on the suction inlet? Where the nozzle comes in contact with the gravel?
So this is the current nozzle u showed working in the other video? I understand the process more or less.
The Caribbean Digger yes but a minor modification after the fact. Google made this video when it uploaded to the cloud. big brother is watching.
Hello there! Did u reduce in the nozzle inside or is it all 2"?
The Caribbean Digger reduced to half inch. this is only a part of the video. entire video will follow when I get the editing done in a few days. shows whole process to make it.
I saw u have another video with the instructions. Is that the video your talking about or are you going to make another vid?
The Caribbean Digger going to put together about 15 segments. shows complete construction. will be 10 minutes or so long.
