Hydraulic System Inspection & Troubleshooting Session 1

[@NathanCEnyart]

I am suppose to start a job and they ask me how much I know about hydraulics. You sir are a life saver! I am still learning at 63

[@daleyurk4369]

Adam and Paul: Thank you so much for taking the time to do this series. This is what KZbin is all about! Also Adam, my sincere sympathy for your recent issues with theft. I've gone through it myself and I totally understand the feeling of violation. I hope you recover, and remember that there are far more good souls out there than bad ones. Keep up the absolutely excellent work!

[@raincoast2396]

Good job. Well done.For you young people out there with an interest, please pay attention to your mathematics lessons. Also don't forget your basic physics. Not only Pascal's law is involved in hydraulics, but Newton's 3 laws of motion also. To become a successful person in life, you must know your basics. Keep studying.

[@viscache1]

As a farmer I face these issues EVERY day of my life. Seeing this has been really helpful! Thanks again! The biggest problem I have on my antique tractor collection is “confining’ the fluid. They find every possible way to piss, squirt, leak, bloop, drip or spray from one point or the other.. Question: So if my backhoe is pushing 18gpm through two 4” bore and two 2” bore cylinders consistently I’m tapping about 20hp off the top of my 70 year old wheezing gas engine...well, that explains the constant need to fiddle with the rpms! Great stuff! I’m probably going to have to watch this series about 8 times to fully get this. I’ve just begun to rebuild hydraulics and as you might know I have very limited skills in this. I’ve been trained in theoretical quantum physics and that has been my life work. Now I own a farm, machine shop, antique furniture restoration service and cabinet making business and we use a lot of hand tools and chemicals...so this is all new to me!

[@matthewmcdermott1276]

Great video, I have been a diesel mechanic for 3 years and have always wanted to learn more about the hydraulic systems used. Very informational, thank you!

[@mikegreen8517]

Great tutorial. Paul does a great job of emphasizing the "take away" from the lesson. Thanks Adam for sponsoring this!

[@azurhrustic1492]

Hey guys! English is not my first language so it would take some time to google research and translate the right word to describe this video... AWESOME? Yup, that kinda does the job:) hydraulic system buliding is an industry that has a whole bunch of poeple working in it that have no idea what theyre doing. So its difficult to get knowledge from that people. I have never seen someone describe this stuff so down to earth so that even a business person like with no technical background can understand. Guys I dont know if youre religious or not but putting this demonstration and course for free to the public in my eyes should be written down as one of your good deeds :) :) cant wait for the next part!

[@reideichner8597]

HI Adam, I have worked with hydraulics for many years. This was a very good presentation and explanation of basic hydraulic components. I can tell your friend, Paul, has taught many classes on this. Great Job! Thanks for sharing with us. No matter what you know, you can always learn more! Take Care, Reid

[@Abom79]

Thanks Reid. yes he has taught this subject for many years, and still enjoys doing it.

[@ruslanleoleoleo9505]

are you producer?

[@remige2006]

How to get out of darkness! Watch a video like this one...what a clear demonstration...real objects with real words....Bravo!

[@harleyghost]

Your training class in hydraulics and your test station is top notch. Great job, and thank you on passing the knowledge of the craft to the young ones. Only thing I might add is about safety. Hydraulic systems can generate a lot of energy. This must be respected. Thank you Adam.

[@colt4547]

When I was a child learning about electricity the fluid analogy helped. Current = Flow / Voltage = Pressure. Sure, It doesn't apply to many situations (Transformers) but it was a useful analogy. Really understanding Paul's basic concepts can lend to your ability to troubleshoot many different exotic technologies. Thanks for the physics lesson Paul, Glad you showed the thermal image as a tool to visualizing the loss of energy, whether caused by a restriction or even a sharp change in direction.

[@razorworks9942]

Adam and Paul, I can't remember the last time I attended any classes! Thank you for the refresher! If memory serves me correctly, I think it was in 76, when I was introduced to hydraulics. Thanks for putting this together guy's! Looking forward to the following series. Razor!

[@Travisfromoregon]

Good refresher :) There are lots of hydraulic designs, so don't be surprised when you pull the reservoir cap on a CAT excavator and find that it is under pressure to aid in hydraulic flow, or when you check the pressure of a pump that is designed to regulate the pressure based upon flow demands vs dead head pump pressure.

[@egdjr1]

Thanks Adam, for letting Paul give this great presentation, for all of us to share in. Great job guys,

[@mausball]

Adam- Awesome series. I understand electrical circuits, and mechanical linkages, but hydraulics are new to me, and I'm looking forward to finally 'getting it'.

[@mi.Dalton]

As someone lost, trying to teach themselves using online resources. I really appreciate this video.

[@jimmilne19]

Much appreciated and interesting video! Well done instruction, clearly put. I am off to my tractor and cherry picker to see how the two hydraulic systems I own work. This is a super useful service you are giving us, Adam. Give Paul a pat on the back and tell him his lessons have influence well over the borders of the good ole USofA!

[@Abom79]

He will be pleased to hear that. He loves to teach this subject, it's kind of like my enthusiasm with machine work and tools.

[@bantisingh735]

[@enterBJ40]

Don't know how old is this series videos but love it ! Thanks both Paul and Adam.

[@markanthonysmith413]

Great video Adam, a few years ago I used to work for a hydraulics company but didn't get much into this side of things - very informative - thanks to you and your buddy. Mark from the UK.

[@binks166]

Adam, I am liking the Hydraulics training,, watched the first one last night. Thanks for putting the series together,, Harvey

[@smtnh]

Great video Adam!! Your man Paul is quite a natural teacher; very nice manner of presentation. We had a fluid power seminar at a local industrial supplier (Eastern Bearings) and his presentation style was similar; very mellow and enjoyable. Keep 'em coming!! Thanks, Sean.

[@Abom79]

That's something Paul has spent many year doing is training. He's a good teacher, and fun to listen to.

[@ypaulbrown]

Hats off to Paul and you too Adam, for a very easy to understand explanation on Hydraulics.......well worth the time to watch.....PB

[@rickeyhall6115]

i do not care how many times i watch videos like this I need all the information I can get good job fellas.

[@joetiller1031]

Great video I worked in maintenance for 40 years at chemical plant we had some hyd. equipment no one knew a lot about them some were kind of complicated plc controlled wish we had someone like the man on video around most of time we changed parts till we found the right one.

[@mack255]

I just turned 65 on 11-14-2014 and still like to learn things . Thank You for you time.

[@craigleemehan]

Adam, really excellent job. The instruction and your video production value is excellent. While speaking to production value, your opening screen combined with your new logo is extremely well done. With how interesting the content is and how professionally it is carried off with many of you "youtubers", I see no reason to watch TV any more.

[@stephendeakin2714]

What a super introduction to hydraulics, be good to see the rig connected to the K&T knee to see if it can show where the problem is.

[@ericcorse]

Many thanks to Paul and you Adam for this training. Very useful knowledge.

[@Patroand]

What a wonderful surprise to see this video this morning. Thanks to both of you.

[@JohnnyLawBMC]

Nicely done. Such a great video. I am taking an hydraulic class in college and your videos are highly recommended. Now I see why. Thank you for sharing this.

[@rockwoodsteel]

Great stuff guys, I operated hydraulic cranes and heavy equipment for a good part of my life. Hydraulics makes my life go around !

[@thatlittleworkshop]

I would just like to add my 2 cents worth if you don't mind Adam. I do a lot of hydraulics with my job and it may not be the most exciting topic lol, but to watch and learn something new is always good. I would like to offer 2 big thumbs up for all that you do for us out here in KZbin land. You offer your experience and knowledge free of charge to all of us. So to everyone who gives you a thumbs down, 2 big thumbs down to them from me. I enjoy all the videos you put together as well as the other channels I watch. I know I, as well as the majority of your subscribers, appreciate the amount of effort and your personal time you sacrifice to educate and entertain us. Thank you very much for all you do and keep up the great work. Although we have never met, I consider you a friend, I even share some of the humorous parts of your videos with my girlfriend. So thanks again and have a great weekend. Ian Little - Spirit River, Alberta, Canada

[@davidfalcon1303]

Hey Guys, thank you for sharing this video. I am a Fluid power technician in Argentina since 90`s and this video is awesome. Thank you. Hope to see more material from you!!

[@LifcoHydraulics]

We can still learn a lot from people like you. Thanks for sharing

[@Buckrun11]

This video series came at a great time. I am building a press for blacksmithing. This will be very helpful. Thanks to both of you.

[@Abom79]

That's cool Steve. Hope some of what Paul shows you will help with your build.

[@AD4MRick]

Guys that was excellent. I knew almost nothing about hydraulics and now is my opportunity to learn. A question about the horse power required. I assume your are talking about the motor required to run the pump? And the size pump would depend on the gallons per minute/hour needed to accomplish the work? Thanks again for this video. If you don't have time to answer the question, don't worry about it. I know you both are busy. Rick

[@hammlybammly3654]

Awesome video, you guys are great. I am refreshing myself before I take a NOCTI test for a Mechatronics job and this is spot on with what I remember learning in trade school.

[@jasta1982]

Really hoping for the next videos, This is a very educational series and I hope you get time to put up more of these since this is the only series I've found that explains the hydraulic system and the troubleshooting methods in an understandable manner! Also on that note it would be great if you went over the use of restrictors in a system (to slow down the movement of lift arms on the way down?) Thanks, Love the channel Jamie

[@German_MDS]

Excellent idea Adam! These kind of videos are the ones that makes KZbin to have any real purpose beside all the junk that you can see most of the time. Thank you and Paul for taking the time to share your knowledge!

[@MyShopNotes]

Great video, thanks. I am looking forward to the rest. I've wanted to learn more about hydraulics but never found the time, this series should be exactly what I am looking for. Thanks Adam and Paul.

[@gdglock]

Great lesson Adam/Paul. Would be curious to see a graphical representation of psi and gpm. Parker rates some of thier pumps at gpm @ a certain psi. Also maybe a basic circuit diagram including a flow control valve and relief valve. Really impressed with your cylinder rebuilds and builds at your day job, I would be asking you questions all day long if I lived in Florida! I have rebuild repaired cylinders for customers, but way short of your expertise. Thanks for all your efforts. Greg

[@Abom79]

Thanks Greg. I will pass on your request to Paul, as he is still working on things to add to the later videos.

[@rupertpowell]

It's a real delight to watch KZbin videos on engineering by people who actually know what they are talking about. Adam, I really like your steady and experienced approach, and Paul seems to be a similar character, equally experienced in his craft. Keep up the GREAT videos and I look forward to the next in the Hydraulics series. PS - I am a sound engineer by trade and although your video work is excellent I am afraid the same is not true for your audio. I have noticed you now have a small shotgun (Rhode), which is better than the built-in GoPro mic, but you really need a LAVALIER microphone clipped to your t-shirt. You would then need a radio-mic transmitter/receiver to give you the ability to walk around the shop unimpeded. This would allow us to hear you WHEREVER you are in and around the shop....without all the room sound. Look at newsreaders and people on TV chat-shows...they all are wearing LAVs. If you need any more advice/help on the audio front then let me know. Roo

[@k5at]

Adam and Phil....EXCELLENT series. I've never understood hydraulics, and this series is very informative. Thanks for all the effort it takes to put it together.

[@PhilG999]

It's Adam and Paul. I (Phil) am just a bystander. But I may have some goodies to contribute. BTW Don't use Teflon tape. It'll split the case of a Hydraulic pump if a shred gets into it. Use TFE paste. It'll dissolve in the oil if you use too much...

[@fuzzy1dk]

Phil Grindle Is taper threads used for hydraulics there? (why else use tape/sealant) I think all the hydraulic I see here use parallel threads and dowty washers or a build in seal

[@PhilG999]

Lasse Langwadt Christensen In some cases of low-pressure applications it can be. In the case I mentioned it was used for a field repair by a not-too-skilled "tech". When I got the hydraulic pump back (claimed to be a "factory defect") I found the case split and what was determined to be a piece of Teflon tape wedged between the gears. We didn't pay for it.

[@Abom79]

Thanks Herb. We have talked about the use of pipe thread tape vs thread sealant at work. Tape should not be used in a fluid system. Loctite makes some good products to seal pipe threads. Some applications you do see tapered pipe fittings, and in others are o-ring sealed.

[@danbentler9742]

Adam and Paul This will be an excellant series. Demonstration gear is invaluable and does great at showing the theory. I do this in my electrical classes. Keep it up people need this. Dan Bentler

[@Abom79]

Thanks Dan. We more more things in store for the videos. Paul is very excited to be a part of these.

[@keldsor]

Hi Adam an Poul ! I love the class there as a prep for my work on my hydraulic press - a project I have been collecting components for over some years - till now I have the tank, the pump and the cylinder and some hoses - so I need some more component before I can start playing around. I will surely view these 4 videos over and over several times in the future - thx so much for sharing !

[@WAVETUBE84]

Cool stuff. Hey Adam, I repaired a hydraulic system one time. The actuator/ram would not extend with full force. There wasn't any obvious problem. The pump was inside of the reservoir. There was a short hose inside of the reservoir leading from the pressure side to the hyd. system. The hose had a leak! I replaced the hose and voila, full pressure... fixed!

[@Abom79]

Awesome! Sounds like a good example of what Paul was talking about!

[@bradcothren772]

Was it a Williams Pump?

[@tomauth3419]

nice to have a guest speaker to introduce us to hydraulics. Can't wait to the next what is next. I found this to be very interesting. Keep up the good work.

[@RutherfordRyan1]

Thanks Adam and Paul, looking forward to next instalment, material was at my level and presented well. Roll on to the K&T repair !

[@danielwerger5641]

Adam, very, very cool...! I have several hydraulic systems, but have no real basics on how they work (self-taught in pretty-much everything). This is really useful information.... Thanks to you and Paul for this...... Looking forward to the other sessions.... Cheers, Daniel.

[@toolguy6057]

Good idea on creating the series. A good review for us guys that haven't worked on it for awhile, and a great tutorial for newcomers!

[@messenger8279]

Excellent instruction video. Will watch all of the series a few times as there is a lot to take in.

[@xmodriver]

GREAT STUFF Adam. Better than I was shown in 101 collage hyd. 30 years ago lol. The rotary is a great use for tapping heads on GUNDRILL machines for water lines ect. As it is a positive drive and instant STOP/ Reverse .for driving GOOD size taps ie 1 inch NPT.

[@bcbloc02]

Great video for the series. It might should be pointed out this is an Open center hydraulic system. There are also closed center systems in which the system is constant pressue and the pump flow varies to maintain it vs constant flow and variable pressure in this system.

[@hankus253]

Would that be like a power steering system on a car?

[@bcbloc02]

No most automotive systems would be open center as well. Closed center is usually seen in higher end machinery that requires fast hydraulic response and maybe even load sensing abilities as well as low parasitic loss from the pump because when it isn't needed to be moving oil it isn't vs constantly moving oil for an open center. The main advantage of Closed center is that you can operate multiple valve functions at the same time and they don't effect each other.

[@hankus253]

bcbloc02 Oops, my error, I was responding to your initial statement pointing out the demo system was an Open center hydraulic system. But you answered my question about a power steering system, thanks.

[@kevinh3979]

bcbloc02 much of what you are talking about applies to mobile hydraulics. And in this case open center vs closed center sort of moves to the next level with the advent of priority flow dividers built into the valve bodies (for multiple operator functions)

[@jmcenterprises9591]

Thanks, Abom79 for this video and series. I never understood hydraulics and always wanted to learn-looks like these videos are exactly what I need. Nicely edited and commented too!

[@SynchroScore]

Definitely informative. When I was in community college, I used a trainer much like this one in my Fluid Power course.

[@bufford14]

Very informative QDM, I've been around hydraulics a lot in my life, but I've never heard it explained like that, that gentleman was spot on with his information, and he went to great lengths to show us how this works with all the demonstration's he did. Also with his hydro table, he did a good job of making that one. Great video. See ya Mark

[@Abom79]

Thank you Mark.

[@reapertx22]

Thank you for your video. I hope you finish the others you planned on. You really helped me figure out what was wrong with my Wrecker and its now back in service. Seriously THANK YOU.

[@w056007568]

Excellent video on the basics of hydraulic systems. As Bill says below, it would be great if you tables shown could be downloaded from somewhere in the future please.

[@Abom79]

Dan, we have plans to add some charts to a google file and have a clickable link for anyone interested. Thanks!

[@stuarthardy4626]

Great vid there Adam and Paul Better get Paul on the K&T I always think things out in my core skill electrical for me pressure is volts and amps flow, you need volts to get the amps flowing , well it works for me as it dose for pneumatics and fluidics Looking forward to the rest of the series Stuart

[@jamesspires8096]

Thanks Adam and Paul this cleared up one thing for me. I always thought that flow = force and pressure = speed so thanks for clearing that up for me can't wait for the rest of the series!

[@doubleboost]

Great start Very well explained I remember a teacher explaining flow and pressure Urinating is a good example open good flow Slight "squeeze" more pressure less flow

[@CompEdgeX2013]

John Mills, always pissin about.... LOL

[@cptbimes1]

I lol' at that one John.

[@Abom79]

Great example John! LOL

[@yubobbanares9774]

Hi sir i have a problem with a two post lift when i lift it up it slowly going down.

[@peterheuts7738]

Thanks Adam and Paul, love this series and learn a lot about a topic I have never played with!

[@famrichards]

Very informative. I knew nothing about hydraulics and that introduction is just at my level. Thanks

[@steelfabmechanic6545]

Great video Adam and thanks Paul for instructing. I work almost every day with hydraulic systems, mostly hydrostatic and closed center variable geometry pumps on heavy equipment. It's enough to make me crazy lol. Can't wait to see more videos for you guys!! Thanks. -Jesse

[@chrispeters4405]

I didnt sit through the whole thing but the biggest thing for me on hydrailuc systems are fluid leaks through the fittings. if you upgrade your system to quick connects and leave the system articulated and come back later, just how much pressure is going through those lines is apparent by the fluid working its way out through the loose nuts on the lines. those fittings have to be very very tight to contain the fluid. and the fluid can never be dirty or contaminated. pressure relief valve explaination was a good part of the video I hadnt seen yet

[@johnfuller6212]

Adam and Paul thanks, this was a great refresher for me. looking forward to the rest of the series.

[@jamesnoonan2242]

Thank you for such an informative video. Broken down to the most basic fundamentals. Looking forward to the next installments. Well done!

[@mattcurry29]

Very nice video, Thank you Adam and Paul for doing these video's. I remember learning some stuff a long time ago, excellent refresher. Matt C

[@mack255]

Feels like I went back to school and that is nice you can never learn too much !

[@ryanquigley7336]

Thanks, already learned more from the first video than I did in the useless class I took at the local community college.

[@billdlv]

Adam & Paul nice job, looking forward to the next parts. Maybe share some of your charts via google drive or dropbox?

[@Abom79]

We are talking about doing just that Bill. Paul is still working things to add to the other videos, and files people can download.

[@artemiasalina1860]

Excellent! I've always wanted to learn more about hydraulics but for some reason never got around to.

[@floridawind1]

Thanks for the video, Paul does a great job explaining the fundamentals needed to understand hydraulics. Gill

[@sfranklandnf]

Really like the series Adam. I have some hydraulic work on a snowblower that I need to start on soon and this is going to help.

[@buddylineman]

Hey Adam, this is why I like watching youtube, I really enjoy learning new things. Great video, tell Paul thanks. Buddy

[@Abom79]

I agree Buddy, its better than TV. It's REAL reality tv.

[@mxcollin95]

Adam this series IS SPOT ON! Thanks for doing this. This is exactly what I’ve been looking for. How cool is it that one of my favorite machinist is the guy putting the video on? 🤙

[@troubleshootinggu]

Abom, Your both sections are very knowledgeable and helpful evedy1, I request you to please upload your 3 and 4 session..... Thanks for knowledge sharing

[@swarfrat311]

Adam, What a great video! This is right up my alley -- I love learning new and exciting stuff like this! A super great presentation! Thanks a bunch! Have a good one! Dave

[@dsadave]

Very beneficial! Thanks! Just got an old loader to work on and have simple hydraulics for the bucket and wanted to get a beginner's primer on flow and pressure. Thanks again. I just subscribed.

[@robertkavich7426]

Great video Adam , I work on my own hydraulic's on my farm equipment , these video's are perfect and will help me understand the systems and be better able to diagnosis and repair those systems . Plus , without causing further damage to the equipment or ME !!! LOL thank you , Bob k

[@chybz]

Hey Adam and Paul, very interesting session and great idea. I really like the subject. Thanks for pushing your channel in new paths.

[@stevenhamer5826]

ADAM!!! get 3 and 4 up asap... great tips and advice !!

[@spaceroamer]

Lots of great information. I've always wondered why the hydraulic filter is on the return side of the circuit instead of on the input to the pump. The way it appears to me is that the low pressure side comes right out of the resivor tank, unfiltered, into the pump, then goes through all the devices including the filter and back into the tank. Hope you get a chance to see this quetion and help me understand why that is.

[@isbcornbinder]

I had to return to this video and use the share feature. Someone who should know better is adamant and loud and he is wrong, again. I have never missed any of your videos. It is February 04, 2018 today. Your videos only get better and more professional with time.

[@danalarrimer1412]

This was a very helpful video in understanding the basics of how a hydraulic system works. Nice job!

[@paulfrench3660]

Brilliant explanation of a hydraulic system. Thanks

[@soloado5084]

Very nice video . I want to ask if the pressure gauge reading at the pump outlet always indicate the resistance that the pump has to overcome in all pump cases ?

[@gholamalialmasi8906]

Thanks for your helpful tutorial.please talk more about troubleshooting tips

[@2007markb]

great video. i have already learned a lot of info on hydraulics just from 20 minutes. cant wait for the rest of the set

[@crashcyberdrive]

Useful Learning, finally have a clear picture of how it works.

[@dillydallydollcomachineand8246]

Adam, Good video I really want to stress safety first . Always good to know how it can kill you before you play with it . Also the eaton vickers hydraulics manual would be worth mentioning in your video for those that want to get more in depth . Thank You for taking the time with these videos it is hard to find entry level videos . My Best As Always , Tighe

[@Abom79]

Your right Ty, and you being a mill write I'm sure have gone though tons of safety training. We do the same at work. Paul has plans to talk about the safety invloved with working on these types of systems, and things not to do. Hydraulic fluid will kill you if it enters your blood stream. Oil injection is a very bad thing. We have more on the way. Adam

[@TomWalterTX]

Looking forward to the rest of the series. One of the projects I worked on was a direct injection fuel injection system (gasoline). 1,000 bar on that system (1 bar = 14.7 psi) yep 14,700 psi... more than enough to server fingers,wrist,arms.... These days they are up to 3,000 bar. I should be enough to scare the bejebies out of anyone working on their own vehicle! Funny part was the EE's were like "whats the big deal?"

[@fuzzy1dk]

sure it wasn't diesel? I've never heard of direct gasoline injection with more that at most a few 100 bar, but almost modern diesels are several 1000 bar

[@TomWalterTX]

Good catch! Diesel with those pressures, 100's of BAR with gasoline.

[@PhilG999]

anonymic79 I have a friend that was in the Nukes. They would hear a SHF (superheated steam) leak and walk down the corridor waving a broomstick in front of them. When the end of the broomstick was sliced off they found the leak...

[@fuzzy1dk]

Phil Grindle I'm not sure the sliced broom stick isn't just urban myth to get the point across. Super heated steam is no more pressure that you average pressure washer and while it will do serious damage it won't just instantly cut a broom stick in half. But the broomstick will still be a good idea, 300'C steam will cook flesh in a hurry

[@PhilG999]

Well I guess a Throttleman on a Boomer might know something about it.. He was. He does.

[@andymandyandsheba4571]

brought back memories of when i was a plant fitter learning about Hydraulic Systems. and fluid power i worked on Hydraulic pumps spool valves and Hydraulic motors when i worked on liebherr excavators and heavy plant i really enjoyed that time except for the winters lol.some times up to your waste in a mud puddles

[@TechneMoira]

Hello Adam & Paul. I enjoyed this video and the other one about essential components in a hydraulic system very much. They are very instructive and clearly illustrated and explained. I do have a question for Paul though: If the motor (and the pump it drives) is slowed down (say through a Thyristor electric power regulator or a variable powersupply) does that reduce pressure or flow? in other words, do you reduce the amount of horsepower transferred to the pump or do you reduce the speed of flow of oil? I would tend to say it reduces flow, but I could be wrong, that's why I ask the question :) Thanks for considering my question Wonderful series, wish there were more of these available on youtube

[@andyknowlton7807]

Great video Adam. You provided a lot of good info in an easy to understand format. I look forward to the next session.

[@GeorgeAustinGTE]

thanks for the video adam and paul its really helping me iv only ever done automotive engineering so my hydrological know how is limited so thanks guys

[@krazziee2000]

very nice equipment and very educational thanks for the series.

[@ChrisB257]

Great stuff Adam. Nice refresher as well as actually learning a few extras too. Thanks.

[@dr.saravananparamasivam7754]

Great video tutorial and lovely clear lecture. Love it.

[@jamesbryant5981]

Excellent video, thanks. Waiting for session 3.
