Making a Mini Hydraulic Pump 

Dear friends, I recommend this video to you ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-S4UJFhoYDl0.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.

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

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.

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!!!👍😸

Thanks for your comments and criticism, I will definitely take them into account in the next videos 🙏❤️

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! 🙂

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

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

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

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 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.

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

Love the unusual fixturing! Well done!

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!

This video is really helpful. Thanks🥰

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 !

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.

Master craftsman. No doubt.

Such a great idea for work holding on the lathe!

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! 💪🔧🔩

Great Lilliputian Project! Amazing workmaship.👍

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

Very good! Excelent!

OUTSTANDING ! No 3D Printing required !

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.

Excellent job, Impressed !

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

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

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

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?

Nice info, thank you for sharing it :)

I like it, very nice project!

That was awesome 🙂

WOW! THAT'S NICE!!😉

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?

It's amazing skills 😇🤗

És um grande porfisional um grande artista parabéns pelo seu trabalho

Number one 😍👌🏻

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 👍

Unique😍👌

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

👍👍 Beau travail Bravo !

Great project! It like your style man 😁

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

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

Nice job, excellent working. 😊

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

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

Amazing ❤

Great work@

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 !!

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

¡Excelente1 GRACIAS.

درود خسته نباشی دمت گرم.

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

Wow thats impressive!

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

Anh là bậc thầy của cơ khí chế tạo

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

AWESOME....

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

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

amazing work thanks

COOL!

amazing❤🎉

Pra que todo esse trabalho, é mais fácil comprar uma bomba dessas ,super barato no Aliexpress

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...

Thank you FOR good idea 😊

👍🏻👍🏻👍🏻

Very very nice, I liked it.

Amazing. Could you tell us its weight, please?

du er den beste❤

Very. Nice. And. Thanks

I liked it !!

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

Magnífico trabalho.

Complimenti per la tua bravura

Класный мини насос молодец.

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

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

very nice work!

Өте керемет кішкентай май жүргізетін насос жасадын жақсы

Wow great work sir.👊👌💗

Muito bom!🤩

abruptly vs gradually I remember old days

Wah. Keren sekali .👍👍👍

مدهش👍 👋🇰🇼

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 😮

Lookz like true ork tech xD

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

Excellent making

Very very interesting

Nice work man 🙂🙂

Excellent video ! 👍

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

Such love and care 💕
