Not many viewers eh! 5 years later and 230,000 + views. Still by far the best description of a bottle jack around. Thanks Mr Pete

[@ezwa9979]

trUe, yet-that’s wats so sad☹️.

[@toddanonymous5295]

Mr Pete, This is why your videos are so invaluable. There are scores of books explaining how various mechanisms operate. But there is nothing like an actual demonstration in three dimensions. If one picture is worth a thousand words, your videos are worth millions. And I will bet your videos will be around long after all of us are gone.

[@mrpete222]

+Todd Anonymous THANK YOU very much!!!!!!!!!!!!!!

[@johnbazaar8440]

Mr. Pete Ignore the naysayers. You do a great job and provide a great service, true to your many years as a teacher. Thanks, John

[@mrpete222]

Thanks for watching

[@jparabie]

Just want you to know you've given me a tremendous amount of knowledge that I have actually used in my life. I picked up and restored an old atlas lathe over the past few months...and due to your teaching... i knew how to do it, and afterwards and onwards... how to actually use it. I don't think I've ever left you a comment before. Due to your experience with these trolls, I feel now that I should have. Thank you for all you do. You are appreciated.

[@445supermag]

When I was a small child, I remember that my father had to borrow a bigger jack from a friend to change the tire on our combine (harvester). It was either 50 or 100 ton capacity, but what I remember that was unique about it was that it had two pumps. A large one that didn't develop much force but quickly moved the ram up to the starting position, and a smaller one for the actual jacking.

[@bikefarmtaiwan1800]

Thanks for this video. No doubt many viewers know the basic principals of how the jacks work but to see where the valves are located and the oil ways go is really a huge help on diagnosing jack problems. You are offering a sterling service to your viewers.

[@mrpete222]

Thanks

[@Makebuildmodify]

I've used this type of jack for over 30 years but never looked inside. Your videos where very educational. I watched and enjoyed both of them. Thank you for sharing your knowledge.

[@mrpete222]

+Make Build Modify Thanks for watching

[@Foxfatherracing]

thank you, keep up the great work, been using jacks for over 40 years, and learned more from you in 2 videos than any teacher showed me. we need teachers like you in our schools again

[@LogicIndustries]

Sir, I'd just like to say that I've greatly enjoyed your videos for many years now, and I have learned a great deal from watching you work. Even though I've been a working machinist for about fifteen years now, I constantly pick up little tricks and techniques from watching your (and many of the other KZbin machinist's) videos. I also very much enjoy watching you build patterns and make castings to build your little engines as well as the digressions that jump out every so often. Very amusing for a similarly grumpy soul (though one who's ~40 years your junior). Thank you for the work you put into your videos. As someone who has also started doing video work inside a machine shop, I know first hand how much work it is to come up with half an hour of usable content. Keep up the good work, sir. Your efforts are not going unnoticed or unappreciated.

[@mrpete222]

+LogicIndustries Thanks for watching & a making a nice comment. I'll check out your vids.

[@Confederatemule]

You are NOT wasting your time on videos like these. Thank you. Mule

[@neilvercueil9119]

I've been staring at some jacks I inherited from my dad and grandad for years wondering if they were worth repairing. Now thanks to your explaination I will have a go at fixing some of them.

[@ronpeck3226]

Incredible timing! Yesterday my floor jack decided to teach me it does not like being neglected. lack of use. Time for a rebuild. Having an advanced organizer will ease my pain, no doubt. Thanks! Mounting my rotary table today using your techniques. Thanks again, Ron

[@johndavid3343]

I really like that you took the time to measu.re the cylinders and work out the hydraulic advantage and then demonstrated the proportion with an actual measurement. Well done Sir!

[@stilyou]

I can't believe I never knew that the visible 'bottle' part of a bottle jack is only a reservoir! I thought I was old enough to know better. Thanks (again) for sharing your knowledge!

[@MyHeap]

Great instructional video Mr. Pete. I knew nothing about how a jack worked and now feel like I have a good grasp of it. Thanks for sharing.

[@llapmsp]

Very interesting how it works when you really tear in to it. Great job explaining the how's and why's.

[@TupmaniaTurning]

Very informative. Used them loads of times but never really thought how they actually work!

[@SuperBowser87]

This was a good one Pete. I was a mechanic for 25 years and used countless types of bottle jacks and did not know the workings inside. Guess I never thought much about it. Really enjoyed this.

[@imaoregonbum6683]

Thank you! I recently was given a Hein Werner O'Boy floor jack and a 12 Wilmar bottle. The explanation you give provided me with the basic information to rebuild both!

[@TreeTop1947]

Mr. Pete, your videos are priceless to the majority of us! Please don't let a very few trolls discourage you, because you have the "gift" of teaching. Those trolls are simply jealous of your knowledge and your "gift" of being able to communicate that knowledge to others. Tt.

[@pakman422]

Dont listen to the critics Mr. Pete. Theres ALOT of people like me who absolutely look forward to all of your videos, especially the 'What Makes It Work" series! Some people have nothing else better to do than complain.

[@temper9993]

THANK YOU, Mr. Pete for the ALL the how it works videos.

[@P61guy61]

Ignore the naysayers. Many more people appreciate your work than not. I love your explanations even if I think I already understand how the thing works. You always surprise me with a bit of knowledge. THANK YOU!!!!!

[@petek210]

Ignore the critics as best you can and be assured the rest of us are enjoying all your efforts. 95,000 subs, you're going to get some jerks, as you probably did in your teaching days.

[@MrGoosePit]

Thanks for taking the time to so thoroughly explain how it works, and for also showing the pathways of all the ports/holes. I and many thousands love all your videos, especially the how it works series. I believe these videos will be watched for many generations to come. That's a great legacy Mr. Pete!

[@zaprodk]

Very good demonstration. I have never seen one taken apart. Thank you for explaining how it works!

[@1971thegrinsh]

Always wondered how a press jack worked upside down. Thank you Mr.Pete.

[@gaymarissaportado9307]

Is everybody still around? Thank you so much mr.pete! A big hug for your detailed information! Its a big help to know how on things!

[@mrpete222]

👍👍

[@generyde9173]

What an excellent teacher. Great to learn from someone else's wisdom and experience. And he did it all without cussing. Amazing!

[@mrpete222]

Glad you enjoyed it!

[@adamf4196]

Videos are still relevant 6 years later. Watched both 1 and 2, thanks.

[@mrpete222]

👍👍👍

[@boguscharlie]

thanks, mr pete. I've never really thought about how these work but your presentation makes it easy to understand.

[@michaelcohen2685]

I always learn something from your videos. Now I understand why my bottle jack won't work horizontally, because of those ball check valves. Thanks for doing these.

[@richardcooper38]

I never thought of how simple the mechanics of hydraulic systems really are. Great video. Thank you for a GREAT lesson.

[@glennfelpel9785]

Excellent demonstration in this series. Thank you for the time and all in presenting these videos.

[@Nolines2002]

Excellent presentation and explanation of how a bottle jack works. I have an eight ton jack that I wanted to repair and now I have the answers to some of my questions. Thank for the video.

[@randyhendrick3060]

Exelent work. I will show my kids this video. Some people have no idea how hydrolics work and this is one of the reasons why we live in so much comfort today. I have adult friends that think brake fluid is to lubricate the brake pads. Thanks again.

[@stxrynn]

Thanks for this. I never took the time to find out what made these work. Makes perfect sense. You are doing good work. Keep it up!

[@tomcarney9852]

I've watched most of your videos, and I learn something ( almost always many things) in almost every one. Keep taking the time, please. There's going to be a time not so far away where there won't be shop teachers. You might be the only way my daughter (currently second grade) could learn these skills. Thanks!

[@russtuff]

Excellent presentation as always. Thank you.

[@mcgyverwannabe]

Thanks for the videos. A lot of the things you show in this series I have a conceptual idea of how they work but have never taken the time or effort to see the detail. I find them interesting, keep them coming

[@johnstrange6799]

Great to add these mechanical functions to the mental catalogue of inner workings. Always appreciated.

[@JohnMcLeroy]

Thank you, I have had a 20 ton jack out in my shed for 28 years and thanks to you I have been able to bring it back to life.

[@mrpete222]

👍👍👍

[@jeffro221]

Excellent two part series on jacks. Very informative. Thanks, MrPete!

[@mrpete222]

Thanks

[@tuffymartinez]

Excellent !!!!!!...Lyle Thank You....Your efforts are VERY much appreciated....Please don't slow down...."WE" all look forward to your videos....You always offer the viewer a positive, honest, informative adventure .....again....don't slow down ! .....Thanks Lyle....J M

[@stevef01]

Y'know what? I have been meaning to take a jack apart for years to look at how it works, but could never find the time - other more important priorities intervened - so this has saved me the effort. Thanks.

[@Hibbie2963]

Tubalcain, Thank you so very much for all that you have done through out your teaching years. You have provided priceless instruction through your schools as well as here on you tube. Thank you.

[@flaskandsarnies]

Nice hands on explanation of something that everyone uses but maybe very few think about how it works. Its a great teaching aid and i wish they'd done this kind of thing when I was at school to explain theories!

[@mrpete222]

Thank you very much

[@novartec]

Mr, Pete, thanks for doing the WHAT MAKES IT WORK series, I enjoy them. Keep it up.

[@countrycraftsman5110]

I marvel at the amount of thought you go through to give your class (us) a lesson in all things fun. Even though i understand the mechanics behind the bottle jack i never put the mental time into it to this degree. That is just one of the many reasons i enjoy your gift to us in the form of video. THANK YOU SO MUCH ! I am in dept to you for your knowledge and kindness of sharing your time and money.

[@mrpete222]

👍👍👍

[@1spdglez]

Mr Pete Thanks for taking the time to share your knowledge.

[@MrNonDescript01]

I really appreciate you taking the time to go through how the bottle jacks work. I showed my kids these videos after they try one in my garage (mechanical advantage is fascinating to them both). Thank you!

[@laneboysrc]

Thanks for that, wonderful to see how jacks work. I watched it with my 9 year old during dinner and it gave me a great opportunity to introduce new physics concepts to him.

[@SamichHunter]

Mr. Peterson, Thank you! I was suprised to hear you say that you had a lot fewer people watching your how-it-works videos. But after thinking about it some it started to make a little more sense. Most of your audiance would be from people who own lathes and wish to learn more about their operation and upkeep. I love your how-it-works videos because I grew up with mechanics in the family and they taught me how to repair things, but my schooling didn't have class that taught hands on milling or how things worked. If they hae I doubt I would have been interested any way at that age. As I have gotten older though I find myself much more interested in this and astounded at how much overlap there is from the mechanical world and the electronics world. As a result, I love learning more about more areas of life. And at 53 years old I find I'm still a student even though high school is far behind me. Again, thank you sir!

[@mrpete222]

+Samich Hunter Thanks for watching

[@williamspinks6259]

Thanks proble saved me a ton of money

[@ericmartin9299]

Thanks for your hard work on making these videos. I feel many of the kids today are growing up with little or no training in these areas leaving them with little common sense. Your work and publishing it in a medium that they are likely to access works to correct some of the lack of training their parents should have been more active in.

[@cpcoark]

Hey Mr. Pete. Don't get to discouraged about viewership on your how it works series. I just want to let you know that I enjoyed this one on the jack. I already knew how they worked but you provide some good information. I had one from a swap meet that always leaked down under pressure. It also came from that 5 letter country. When you showed how much dirt was in yours I drained the oil out and flushed it several times with kerosene. Man did the dirt come out of it. Refilled it with jack oil and now it holds 4 ton without a problem. So even though you don't get a lot of views, you did help this old dog out.Al

Sir, can you spare some moments from ur busy schefule to guide me about the circuit. Other theoratical design calculations complete, only the design of appropriate hydraulic circuit is pending. From your coments,I getherred that you have an execllent knowledge about the subject matter and if you desire to guide some one, you can do so . May i hope you shall spare some moments from your busy schedule to guide . It shall be great of uou, My e mail is [e-mail] & whatsapp no is [phone] for any interaction and advice for guiding. Sir, should i expect your honourly guidance. With sincerest regatfs

[@robertholland9778]

ww_big_a could you please tell me where and how much fluid to put in a big red torin air and hydrolic jack?

[@larrywheelock9754]

Watched both videos on 8/3/2018. You have done a very good job of explaining and showing how a hydraulic bottole jack works. There are many variations in the construction of manyof these jacks, but they all work the same, but some of the cheap ones cannot be disassembled as easily,. Getting the air out can be very frustrating. You said that you are not getting many comments, but you are making a very valuable contribution. Thank you.

[@mrpete222]

Thank you very much for commenting and watching

[@abnerdoubleday6145]

Excellent video. Really enjoyed seeing the guts of the bottle jack. You did an excellent job describing the math behind how it works as well. Loved the Sharpie on brown paper calculations as well. Simple straightforward and clearly presented. Thanks.

[@mrpete222]

Thank you very much

[@rwallace9848]

Mr Peterson, awesome video! please, please keep doing the how it works video series. You are an excellent instructor and I always learn from you. You have a superior teaching style. Thank you for bringing your time and experience to you tube. Thanks!

[@Zt3v3]

Thanks for making these videos Mr. Pete. You bring back many years of shop classes. My Dads home and shop was lost in a forest fire last year, I salvaged 3 floor jacks, all of which need rebuilding of course. I've never pulled the ram from a Hydraulic jack before and I wanted to know what type of seals were used, or as I've learned from your videos, cups, like a wheel cylinder. I don't know if it'll be worthwhile to rebuild these jacks, even though they were good US made units, but one of them was my grandfathers 3 or 4 ton Walker Jack, and to me, it's worth rebuilding at almost no matter the cost. I'm sure I'll be able to find o-rings and seals, but I'm not sure where to find cups yet, once I get measurements I'll start with the auto parts store first I suppose. Anyways, thanks again for your video.

[@mrpete222]

Thanks for watching--sorry about the fire

[@UBO58]

Excellent explanation! Thanks a lot for this and all your other videos! Until now, I only watched some of them, but I learned a lot by each single video. Please keep on your great work on youtube!

[@Keith_Ward]

I love cutaways! Seems like a 90 bandsaw cut through the middle of the ports and cleanup with an endmill would work well and show most everything.

[@gordoneckler4537]

Thanks for a fine explanation of the workings of a hydraulic jack. I've always been curious what they looked like inside and now I know.

[@DroneManMurphy]

I really enjoyed both of these videos. It’s funny how we use these things we don’t understand how they work and that was very helpful.

[@RGSABloke]

Mr. Pete, 'The man who knows everything, knows nothing'. Keep sharing and we will keep enjoying young man!!!!

[@davew368]

What a great explanation. Thanks Mr. Pete. I had a very basic understanding of the principle but not the specific way in which it was applied. I've got a cylinder that I overloaded that has been laying around thinking I would try to fix it. With the class on how they are put together and an understanding of the valve system along with how it should come apart I think I'll give it a go...probably more expensive to fix than recycle but I ought to learn something in the process. Thanks again for all the great videos.

[@tedfarwell9812]

Great video! I enjoy them very much and learn something from each one. You're an excellent teacher. Thanks for taking the time to make them.

[@blazeabong]

i love your videos mr pete and all the knowledge you are passing along to others like myself i thank you

[@Angus_McGyver]

I already had a good understanding of how jacks work, but it was still very interesting to see it all apart. Pay no mind to those who lack the mental acuity to appreciate your presentations.

[@kevinwillis9126]

may i say that was very well explained as always... thankyou sir for sharing...

[@davekellogg6819]

Thanks Mr. Pete!! I don't recall learning (back in school) about the various classes of levers, so I had to look it up. You are much appreciated.

[@LincolnSP150]

Very informative, you have excellent teaching skills, now I understand bottle jacks better then I ever did. I especially like how you explained how a jack can be modified to operate up side down, I often wondered why, and how. Now, thanks to your video, I totally understand. Thank You

[@user-kg1pj1mz4l]

Thank you Mr Pete for your awesome video. I have a lift cart that has garbage for manual. So I needed to know about the theory and mechanics of hydraulic jacks. Your videos on the subject have been extremely helpful. I loved your explanation of the oil passageways and how the valve system works.

[@mb345]

Great video! So clear that you have years of experience in teaching. Thank you for taking the time to share your expertise with the wider audience.

[@Kalkaekie]

Another good video ! Appreciate all that you do to make these videos ! :):)

[@terryjennings2356]

Loved this two part series!! Such an amazing breakdown and demonstration!! Thank you for putting so much time and effort into making these videos!

[@mrpete222]

Glad you enjoyed it!

[@davidyarra5648]

Nice vid as always. I "fixed" my hydraulic jack by renewing all the o rings and it never worked properly again! Your distinction of the low pressure side and tube being only a reservoir, are the key understandings for me. Keep up the knowledge transfer, a thankless task.

[@wmichaels362]

Thank you. I like the detail and your every-man explanation of engineering /physics principles.

[@AmateurRedneckWorkshop]

Another great explanatory video. Thanks for sharing.

[@rotormotored]

I found the need to learn this because I have a few old jacks laying around my shop and decided to do whatever I have to do to put these jacks back into service. As always, I watched your video and learned something. Thank you, sir.

[@mrpete222]

Glad to help

[@hogflyer62]

Another excellent video. I'm going have my son watch both parts so he can see a practical application of what he has learned in his math and science classes.

[@richardredcastle7911]

I enjoy all your videos and your very dry sense of humour the most!

[@xzendor7]

Thanks for sharing your 50 years of knowledge with the rest of us that like to learn. Forget the naysayers, they are just jealous of what you are doing. Great Job an Thanks Again.

[@mrpete222]

Thanks for watching

[@nativearizona1]

You gave an excellent presentation of how a bottle jack works & functions, for a layman like me this was very informative, thanks for sharing your knowledge.

[@jackrichards1863]

Resealing a trolley jack I'm after info to show how the ball seal is fitted into the device . It has 2 Bearings for two passages; and a ball end on the pressure lock tap. You came close to solving that except also, this shows me how to fathom it out with some stout monofilament and some soft wire . I can at least go and figure how the darn thing is meant to work. A problem crops up since somebody beat me at getting inside the works and I cant easily be sure if springs were required in any all or none of the check valves straight away. Thank you for being a good helper, following my viewing of up to 5-6 others that just did not go in the right direction, all the way or not with a similar enough device to be of any use! It was a good idea to subscribe to Mrpete222 but today I had to renew my sub, I also learnt.

[@UnbeltedSundew]

The videos are great I like every one of them. I think my favourite though is the Chinese windlass and differential hoist ones though because the concept behind the mechanism is so simple and elegant. Thanks for sharing these with us.

[@tomgullan3565]

Mr Pete, thanks once again. I too knew how a hydraulic jack worked. I watch your videos because I like your style and chuckle at your patter...!! Your video on the mole traps still makes me.laugh. Keep up the goog work.... All the way from Bonney Scotland.

[@davidcampbell4743]

Hey mrpete222, just watched your videos on hydraulic jacks and found them very informative. I learned a lot about hydraulic jacks that I didn't know, but aways wondered about. Please keep up the cool videos I really enjoy all your videos

[@ThePrometus]

It's a very nice explanation. Image, sound and camera management is very good. A complete tutorial and training video. Great. I think I'll be watching these pages often from now on. Thank you for your hands. Respects.

[@mrpete222]

Thank you very much

👍👍

[@leftturn99]

The best class on U tube starts with Tubalcain!

[@philcal2000]

I have an hydraulics business in Australia and never accept jacks for repair because it would cost at least twice as much than to buy a new one , but now I have a video I can refer them too... thanks very well explained...

[@mrpete222]

Thank you very much for watching. It’s good to hear from an expert on the subject. And I fully understand how much work and expense is involved in that type of repair work. But I bet many of your customers think you were just trying to rip them off. Keep up the great work.

[@jdcastillocastillo3492]

I really love these videos keep up the great work.

[@AdamChecketts074]

Outstanding. We are going over a hydraulic section in our technician course and this insight is nice for understanding in greater detail what we are looking at. Much thanks!

[@mrpete222]

I’m glad it has helped you and your class

[@bradsbroadcast]

Really enjoyed your explanation and demonstration... I almost understand how hydra. jacks actually work now. Thank you. Brad

[@cpo1wh45]

As always, very nice and worth while. Thank you.

[@jmstew642]

great job on demo. i always wondered how those work. keep up the good work. i am sick in bed alot, so your teaching skills and inquisitiveness is awsome. i learned something, thanks.

[@petercunningham4000]

Thank you for posting this very informative video. I have never seen one taken apart before, so I have learned something. THANK YOU.
