Dear friends, I recommend this video to you kzfaq.info/get/bejne/iZqFfamZ1L-onGQ.html

A gear pump, especially a small one like this requires very tight tolerance and smooth surfaces to reduce internal leaking if you want high pressure. But for a low pressure application, or just a fun project I think this was very nice and clever.

As a person with tool-making experience I can see this person does not have the proper knowledge about best practices in machining (i would call them sub-par) but his tenacity, endurance and calmness gets him to the goal.

That is pretty cool. My one bit of advice if you want to make higher precision stuff is to know that threatds are not too accurate for locating the centre of holes. It is better to use dowel pins or some sort of expanding mandrill

Very nice work. I would like to see you hook up a pressure gauge to the pump to show us how much psi it puts out when you dead head the pump.

Thanks for the video! I have a very well equipped shop and sometimes forget what can be done with a little ingenuity!!!👍😸

Muito boa a ideia,para pequenos projetos,continue assim PARABÉMS,que DEUS acompanhe seus caminhos,um forte abraço.Aqui BRASIL.👍

That was a great demo to convey the basics of a hydraulic pump. From scrap steel to a useful pump, awesome. Thanks for sharing.

Bravo pour ce travail minutieux et précis. Quel plaisir de vous voir travailler. 👍

Wow! You're proof that where there's a will, there's a way! Brilliant job! You didn't let anything stop you! Genius! 🙂

I know how to like, subscribe, and get notifications. I usually close the vid when I see that animation. This was an interesting project so I kept watching. I could do without the constant reminders.

This can be a awesome thing if only some companies mass produce hobby products like these. Fine surface qualities and tight tolerances can be achieved via hard sintered metal internal internals. It could build considerable amount of pressure. Rerspect to video, i was thinking some guy trying to build something fun with scrap but it turned out quite quality piece in the end. Check out the last seconds of the video, you can clearly see electric motor suffers and rpm decreases, this shows that internal leakage of the pump is quite low.

I designed and resin 3D printed pump even little bit smaller than that and it works beautifully. I had only 4bar gauge and it topped that pretty quicly. Even did 24hour sontinious run and didnt brake. was fun project. Allso good job on yours!

Sticking your finger in a rotating bore of similar dimensions, especially with sand paper, is a sure way of having the flesh ripped off the bone or finger tip being twisted round and round.

I would NEVER use silicone on any oil pump cover. controlling the amount of goop is critical to prevent it from going into the gear chamber. I have had zero success with it also in terms of longevity . May I suggest getting a piece of thick glass, meaning at least double the thickness of window glass (get some other kind due to waviness in window glass), and tape a sheet of a good quality 400 or 600 grit sandpaper to it, such as 3M or Norton, etc. Hold the part with the mating surface against the grit and hand mill the surface for an almost 100% flat surface that won't leak. I have done this to oil pumps when restoring engine for cars that were being restored where I used to work. We did cars that you just cannot find the parts and must become creative with making things work. You would be surprised of new parts that have imprecise fits that show up when using the sandpaper and glass surface. If you have a machinists surface plate, you could tape the sandpaper to it but it all depends on what surface plate is used for and how it is cared for. Just clean the surface completely when done. BTW, if done correctly, the 2 finished surfaces will not leak. Cool project and it gives me ideas. Thanks.

Careful and punctual work. I like it. Thank you.

For all who want to build something like this. NEVER hold small objects with your hands when drilling them !!!!!! ALWAYS clamp them down, your hands are precious precision instruments not dumb clamps !

OUTSTANDING ! No 3D Printing required !

Classy work, nice machines, great skills, I'm jealous.

So many experts here, CA glue to temporarily fix position, I learnt something today. Off centre lathes the block with a 3 jaw chuck 👏🏼👏🏼👏🏼, why I didn’t think of that?? You really knows how to use your tools my friend 👍

Impressive work on this mini hydraulic pump! While it may not meet the requirements for high-pressure applications due to tolerances and surface smoothness, it's still a clever and enjoyable project. I'm curious to see how it could be adapted for low-pressure tasks or serve as a learning tool. Keep up the great work! 💪🔧🔩

Love the unusual fixturing! Well done!

Wow, props you cut through that block with a hand saw! I bet that took a while!

Why do you spray over the parts after gluing and what is the spray? Good video, thanks.

Such a great idea for work holding on the lathe!

Id love to get my hands on one of these for a prototype Im working on..

És um grande porfisional um grande artista parabéns pelo seu trabalho

Top show perfeito o trabalho 👏👏👏🤝👍💖🇧🇷🇧🇷🇨🇮

Great Lilliputian Project! Amazing workmaship.👍

Nice info, thank you for sharing it :)

That's a nice little build. I made a model excavator arm out of syringes as a fun project, this could be the upgrade. What pressure does it create if you cap and dead head the pump?

Fantastic video and beautifully made!, liked and subscribed I would be interested to see it connected to a gauge to see how much pressure it can develop...

Nice project,nice work.What are the chances of finding those gears just laying around?

Thankyou very much sir, Till Now i do not know about hydraulic. But you have taught the good concept. Once again thanks

Very good! Excelent!

Amazing, I run a lathe but I dont have smal stools as you, I would like to make one pump for me too

I have all the tools you used here, but I DONT have the skills you displayed here. Hats off to you bro and a fine build !!

Excellent job, Impressed !

Good work as usual. We shared this video on our homemade tools forum this week 😎

"At home?" you must have an awesome home with all those machine tools!

I like it, very nice project!

Great project! It like your style man 😁

This video is really helpful. Thanks🥰

Should try a Lexan cover!!! It'd be neat to see it live! Great video!!!

Master craftsman. No doubt.

BEAUTIFULL, Magnifique! THx for inspiring me; merci, ça m'inspire.

Nice job, excellent working. 😊

Unique😍👌

The amount of times your like a sub pop up flashes is really distracting and off-putting

Kudos to you. Couldn't slip bearings be good enough for those cogwheels? Did you test how much pressure it can generate with that (drill) motor?

Working on one about three size for fuel injection pump- very cool

A bomba de óleo do motor do Fusca já tem uma quase pronta , boa idéia..

👍👍 Beau travail Bravo !

you know if you put an electric motor on that, with a closed loop hydrolic..that s some thing for the tool box... i like...good job...

Amazing. Could you tell us its weight, please?

It's amazing skills 😇🤗

That's amazing perfect keeps on working you've inspired me

¡Excelente1 GRACIAS.

Nice job, did you measure how much pressure can you reach?

Number one 😍👌🏻

Hi, really nice video! Where did you find the hydraulic cylinder? I am searching for this scale but cannot find one

Amazing job... invest in some high quality lathe bits, they make life easy

You didn’t need a bearing on both gears?

Neat pump. I wonder how it would compare to a 3D printed plastic pump for longevity.

Өте керемет кішкентай май жүргізетін насос жасадын жақсы

That was awesome 🙂

Complimenti per la tua bravura

WOW! THAT'S NICE!!😉

Just when I was thinking about how to filter the oil in my lathe & mill to try and save money. It’s so expensive I can’t afford it. Thanks 😮

Muito bom!🤩

Круто. Только вот чтобы было надежно делают посередине канал отводящий жидкость обратно. Дело в том что попадание масла между зубьями шестерёнки без этого канала разрушительно для данного насоса. Это можно увидеть на всех подобных насосах

Well its a cute project and a learning experience. I would like to see the psi Guage results.

Instead of the third drill and tap why not use the bridgeport? (Just curious)

Really nice! And that actuator you are using in the very end, is it also self made, or bought? If bought, can you share where? P.S. Aha, I found the video. 🙂

Класный мини насос молодец.

Very very nice, I liked it.

Cool pump! I didn't think gears could pump liquids🤓

Wow thats impressive!

amazing work thanks

Very, very good!!. Thnak you for share it!!

Wow great work sir.👊👌💗

Дааа, столько работы!!! И сколько давит? Возьми на этот мотор закрепи шпильку а на трубке в конце привари гайку и получишь шток ! Думаю мощность будет такой же, если что редуктор в помощь!

Hey i really like your works. I wamna try to make it too im my house. I want to ask what gear you use? Is it just normal spur gear or should some specific kind of gear? Hope you kindly answer me, thanks you

Magnífico trabalho.

Good job ! You need to measure pump maximum output pressure )

amazing❤🎉

Such love and care 💕

Wah. Keren sekali .👍👍👍

Thank you FOR good idea 😊

Wow very good job my friend 😍❤️❤️🎉

Great work@

AWESOME....

Anh là bậc thầy của cơ khí chế tạo

I guess it would have been cooler if you machined the gears too it would have been cooler but still pretty cool

How did you get this much metal??!!

I always wanted a 2-bricks in a lunch-box pusher contraption. Very useful for pushing 2-bricks in a lunch-boxes.

COOL!

Там под зубчатыми колёсами должна быть веточка, чтобы остатки жидкости при сжатии по ней выходили. Если не будет веточки, то современем от сжатия жидкости между зубьев придёт в негодность. Так как эта сжатия жидкость пытается раздвинуть зубчатое соединение.

Lookz like true ork tech xD

Awesome. Motor seems week though. I’d like to see it with a much more powerful one
