- Me and the Dewclaw made an all terrain forklift out of an ancient forestry skidder.
Thank you for your help! Please let me know if there are specific topics you'd like to see.

So , I googled Hydraulic injection injury ... I won't spoil it for them folks that may be so inclined to look but for those that aren't , think cherry bomb in a watermelon .
Balaclava Bob id never heard of the term before. Holy ol’ Fak I thought hydraulics we’re safer than Pneumatics. That’s awful
@@brandonbenjamin9452 yeah , I still haven't unclenched yet lol
Yeah I had to watch the safety videos. It can be a minor injection feel like a needle prick say in a finger, then feel fine. But in around two hours you are dead
Nathan Garcia wait really? You die from it? Does the oil get into the bloodstream that easily?
Or go work in steam systems looking for a leak with your fingers... what fingers.
You know you've spent too long driving hydraulic things when you rev your car engine to make the electric windows go up quicker.
my friends truck has electric windows that go up faster over 2000rpm
Yupp know the feeling. Do it about every night after work.... I've even tried to pick the blade up to move my truck lol
Or when you rip the wiper stalk off your half ton trying to shuttle into reverse......
I used to try and put my car into reverse with the blinker stick haha
I've done that too! Or hop in the truck after a day of running a loader and smack the blinker down to back up.
Oh boy the toys keep getting bigger and bigger, where will we be in twenty years? "Gentlemen, I just bought this decomissioned oil tanker..."
Have you been talking to Babydoll?! Actually, they aren't *TOYS* and they are getting *smaller*. Just more of them.
I thought the rule of thumb was:
Fun to use = toy
Chore to use = work
@@arduinoversusevil2025 I keep telling myself that I will eventually find my passion in the production of "jewelry and small miniatures", all the while I keep finding myself in the company of industrial dinosaurs, taking up half the shop space, waiting to be fixed "one day"
I'm waiting for a Space Shuttle to show up!!! I know where one is sitting just down the road 😉😉😉
The only difference between men and boys,
Is the prices of their toys!
9:12 I would like to make a point for pumps creating pressure: When you are a pump technician and the pump you were meant to service months ago failed, you suddenly are under a lot of pressure.
AvE, I have been watching you since high school, and the more I watch and think, the more I understand. Partially inspired by you and your great channel, I am now an A&P aircraft mechanic working on big business jets. I have just started down the path, and I am already meeting skillful masters and experiencing amazing machines through the technical side of society. Through your channel, I saw that guys could make a living using their heads and hands fixing difficult and complicated systems, and learn a lot about the world and how its systems work in the process. What you say about parallels between systems is absolutely true, hydraulic systems are almost perfectly equatable to electrical systems. Pressure is voltage, volume and displacement are current, orifices are resistors, pressure drop is voltage drop, valves are switches, etc. You have taught and inspired me (and my brother too) an immeasurable amount. Thanks for all your infinitely informative and hilarious work.
A years-long loyal viewer.
are you me? Been watching him for ages and going into A&P as well
Hehe, you fellas didnt happen to go to naa did ya? Im in the same boat my friends.
Kodey Hughes nah fam going to a community college 147 school in VA
Current is volume flow *rate*. Current is electrons per second, hence the rate part.
So, you should know all about the "Purple Mist"...
I don't know why I need a skidder on the back 40, but today I realized it's imperative that I have one.
Anyone else expecting the sound of smushed light fixture, darkness and cussing when he ran the forks to top?
ThisOldTony definitely would've featured such shenanigans 😂
@@SomeGuy-vo7we Yeah, I think ToT has spoiled me, now that I think about it.
Tinkles from the bulbs and the operator?
@@mfree80286 Bulbs, yes. Pretty sure the operator needs a bit more than that to get beyond the "ohforf'sake" point of the "shite that happens" scale at this point.
I was expecting him to max it out.
I can sit in a classroom and listen to a lecture about the same subject and not have a clue what is being discussed. You have a very unique way of sharing information and it’s amazing the difference it can make
OMG, this video has everything one needs to know about a skidder's hydraulics explained to us by our favorite Canadian TH-camr. Not only does he spread the wealth but we hear a master at torquing the fittings with the grunts telling us the tightness was spot on the correct number.
Never enough time to do it right, but plenty of time to do it over. :-)
Dang right
Here same it goes
I've heard and used it as "there's always time to do it right the second time"
"Release the Shmoo!" If there's anything I've learned from Ave it's to yell this whenever anything leaks.
@Captain MufDyven How revolting! Liked and subscribed.
But surely you have to say this just BEFORE the schmoo starts flowing?
@Captain MufDyven I was responding to Peter R
Shmoo and scmutz is the stuff of nightmares in my job 🤣🤣
~100 years ago AvE would've probably been a famous poet :)
Mirodin Infamous, more likely.

Well I learnt a whole bunch of stuff I didn't know there, thanks. I was a bit disappointed that shards of fluorescent light didn't crash down when you raised the forks out of frame.
I learned more from this video than I did when I took a Fluid Power Systems class...
Self-diagnostic via pools of oil got me good. had a bit of sandwich stuck in my gobbler!
I worked a place everybody had to qualify on forklift (pretty common here in Lower B.C.). One day I was moving something at the truck's weight limit for our maintenance guy and the truck wouldn't lift it. Because I had paid attention in the "instructional video" (you know the one, also titled "How To Wreck A Forklift") I immediately looked at the floor around me. He was highly impressed but told me "It ain't leaking, it's just old. Stand on the go pedal." I did and it worked.
I was so glad I didn't have to go oil-skating that day.
I've drove big forklifts for a lot of years and now I understand why trying to do multi functions at the same time doesn't work very well an falls on its ass .... thanks for the knowledge AVE
Wait those big ones have issues doing multiple things at once? My small little Nissan I rev her up to the rev limiter and pull pretty much every function at once
It would help if the fork-lifts you had experience on weren't under-powered and under-built in the hydraulics department. I have some experience with more modern diesel-electric Container Stackers and Industrial forklifts, and when throttled up, they have all the juice they need to run multiple functions simultaneously. It's all a matter of having the correct design for the hydraulic circuit and pump(s).
Well they were underpowered I mean they're the bigger ones...8000 lbs at the front.... but I've lifted scissor lifts that are probably 3,000 pounds ...even lifted them up three stories with my ass rocking back and forth with two guys giving me extra counterweight on the rear.. crazy stuff I've even tipped a lift before on its side scared the s*** right out of me
@@MFKR696 so kinda like a bobcat with a throttle that you can position however you want?
@@badtrip801 Nope. You just hold down the clutch and rev them up with the throttle pedal when you want to use hydraulics. Tis why most forklifts have 3 pedals. Farthest to the left is just the clutch, in the middle is clutch and brakes, and to the right is throttle. Tis so you can rev up the hydraulic pump when you don't want to stop moving yet. Also, I intend no offense, but an 8000 lb capacity lift doesn't qualify as big. When I think "big forklift" I'm thinking of those big fuckers that I used to stack shipping containers with, or foundry forklifts. 8000 lbs is on the low end of things for a modern forklift. To put it in perspective, the smallest forklift I ever operated was a Raymond Dock-Stocker (the Cadillac of electric lifts), which weighs 10 000 lbs and can carry around 6000 lbs.
DCV is a Directional Control Valve *Writes D V* you get it
You have the lexicon of a very well educated sailor.
Just sayin'...
Super Geek Also many a Texan!
jltsoyowdyc Jltsoyowdyc well since all things are made of atoms, doesn’t that make all of us “atomic”?
The less educated ones either quit or end up fish food 😜
AvE is a blast to watch...his attention to detail and his knowledge are impressive... 🙂
You forgot about the DKO fittings used over in europe! You are certainly right about the -5 fittings though. I'm an engineer for Aeroquip, cool to see some of the hoses I work with every day pop up in your video!
The schematics are mind bending. I’m an electrical type, and I kept seeing a light emitting pump.
😂🤣🤣
AvE, my chemistry professor laughed his eyes outta his sockets when I said "release...the schmoo" when opening an oxygen calorimeter.
Crowning achievement, promote ahead of all peers right thar.
Thanks for explaining and teaching! My brother was an industrial mechanic, worked a lot with air, hydraulics and electrical systems. He passed away several years ago and I’ve finally found someone as good at explaining systems as he was. You teach a little in every video. I wish you could see the light go on when I get it. Thanks again.
I work in rolling stock now. This reminded me how much I miss hydraulics, all greasee, and hearing the return kick in once you’ve given all she’s got.
Love the schematic, takes me back to mech school.
*Me in interview*
Interviewer: So, do you know any CAD softwares?
Me: Yes I know AvECAD
Interviewer: What?
Me: What?
AvECAD for mechanical engineerding and DaveCAD for electrical engineerding.
And just plain CAD: Cardboard Aided Design.....
I was riding around in one of these beautiful machines long before I ever knew what school or work ever really was. So awesome to see one on the channel. The old cable skidders were the real deal.
What we lack in displacement. We can make up for in rippems. The story of Dewclaws life...
Damn it AvE. you got me with that one. Quietly hanging out in my corner cube with the earbuds in ( AvE not safe for work)and bam. Snot bubbles and snorts of laughter.
"What ya lack in displacement, ya can make up for in RiPPeM's!... story o' DuClaw's life."
That one got me.
Thanks for the great explanation of hydraulics
Nice Detroit drop with the 8v92
New AvE vijeo? Drop everything!!
I designed a Fluid circuit in Festo fluidsim when i was 15, designed a lift for a media rack in my home theatre. haven't seen a fluid schematic since then. brings back fond memories.
Not OSHA Approved? Like I told our contractor Electrician on a deployment to Afghanistan when I said I was going to wire American 220 and Euro 220 into the same datacenter racks so that I could have generator redundancy (long story), channeling my inner Théoden from Lord of the Rings, "OSHA? OSHA has no power here."
How did that work with the 10hz delta?
@@paperburn Yeah I figured it would work, but also figured there are quite a few variables depending on different types of gear in the racks.
@@ShainAndrews More often than not those power supplies are specced for 50/60 Hz anyways and the fancy ones are "universal" and have an input range of 100V to 260V. With a switch mode power supply there's just some fancy power factor correction electronics, some filters, etc, and then it's straight into a rectifier so even if it's not technically rated for 50 Hz that just means there will be a bit of extra ripple on the primary side DC bus. Capacitors degrade over time so the circuit is designed such that even after 10 years of ageing the ripple will still be acceptable and within spec. Maybe if it was already really old 50 Hz instead of 60 Hz could tip the scales just enough to keep it from working, but normally the circuit is overbuilt enough that 10 Hz lower will still be totally fine.
Yeah, 50 or 60hz doesn't matter at all when it's all 12/5/3.3 VDC coming out of the power supplies
Had a guy do that in Turkey, the problem was that between the American ground and the Euro ground there was a 48 volt difference, blue a hole in a great deal of of electronic boards! just sayin.
20:39 - "There's never time to do it right the first time and yet always time to do it right the second time". Never truer words spoken. You don't happen to work in software dev too do you?
Engineers have always believed in "iterative" design. It's only in the corporate world they expect planned perfection because they've never built anything before.
A friend and I always call that "we don't have time to stop for gas"
You are the reason that people love Canadians!!!!
You've gotta love the legacy of imperial units in all forms of plumbing.
I feel confident in my mechanical abilities... the more I watch the more I realize I'm an idiot.
The Mark of a wise man when learning knew things makes them realize how little they actually know.
Tim Walker hahaha lol I’ve been a heavy truck and CAT heavy equipment mechanic for a while. I changed over to the automotive industry recently... I am struggling hard simply because I don’t know automotive mechanics lol.
You should get that Hand Tool Rescue guy over for a little restoration project. I believe he's local, continentally speaking.
:-)
I've been an elec-chicken and pusher of small groups of fairly calm pixies for a long time, but mechanics always eluded me... Thank your for your this vijayo, it was both entertaining and instructive!
As a retired engineer, let me congratulate on being the most brilliant purveyor of practical hydraulic engineering fundamentals that I have ever heard from. Please consider teaching at university to transfer your vast knowledge to others that need this essential information.
In case you missed it, that's what he's doing here.
@@Onesize17 Not at the level of detail demanded by a university course curriculum.
AvECad 2.0 looks dope. I'm still using the bootlegged 1.2 version.
The little spots of oil on the ground are a visual indication that you still have oil in the tank.
Been a yellow iron mechanic in training since 12... Currently 24 and now chasing down machining metal . Gotta say you are one hell of a leatherman and im loving these mechanical videos
Glad to see AvECAD still getting updates
pssst. Can anyone on the darkwebs get me a copy of that AvECAD 2.0?
Still looking for the 2018 AvEictionary
@@codycharles7147 Urban dictionary should just have an Ave section. Agreed?
@@codycharles7147 I can't recall where I saw it but there's a ginormous list of "AvE-isms' and their translations floating around in the cyber.
It is a fork of DaveCAD.
Just get the unregistered version like him. Gotta ignore the watermark though.
Shirt quote! "Forks go up! Forks go down!"
I love your channel man. Thank you for breaking things down in a way my unskilled mind can understand. Maybe one day I’ll be half as competent.
@AvE got my warning stickers from you the other day. They are great thanks and thanks to your good lady in the postage sweatshop
8v92
Nice choice of engine!
Andrew Sobek vicegrips, if you know ya know.
Had an 8v71 and always dreamed of stuffing a 92 in the ole bus conversion so i could pass my friends climbing an 8% grade. Instead i was stuck hunting between 1st and 2nd at 20 mph.
the 8v71 detroit was a badass engine, always loved those old 2 strokes.
Not a hydraulic robot exactly but 4 of our transfer machines use hydraulics for the units Z-axis movement (about 60 spindles total). The quills act like a large, hollow, double rod cylinder with the spindle inside them. Oil is controlled by a Bosch proportional servo valve (the valve has it's own feedback circuit to know how much it is open). The backside of the quill has a Heidenhain optical scale that reads the position of the unit itself back to the PMAC. Not a bad system; reasonable accurate, harder to get chips inside the workings, much less susceptible to vibration than ballscrew units, bearing heat is removed by the oil and units can be made more compact since you don't need the room to stick both a spindle motor and an axis motor. The newer 11 transfers along with the mills and turning centres are all screwballs. FYI: JIC, ORB, NPT, BSP are not used in all hydraulic systems the world over. ALL Italian industrial nuisances use parallel metric thread for the hydraulics, will only start threading if you are 100% aligned, been at it for hours and are getting shot glasses ready for the Drano. Joint Industrial Council (or Jerome Increase Case) tapers are the fittings of Gods!
Cool. What brand of machinen? FYI Metric parallel is BSPP.
@@arduinoversusevil2025 The hydraulic transfers are all BTBs, 8-9 station, 18-30 tools, some have Z and U axis, some have Z and Y axis, some Z axis only. Max out around 550 parts per-hour. The high speed Riellos with vision cells on the other hand can spit out 1500 parts an hour. In between you have Portas, a Gnutti, other Riellos and other BTBs of all shapes and sizes. From machines with 12 stations and 42 spindles (apparently the largest of its kind) down to 4 station and 4 spindles, each with a 8 tool turret and a machine with 6 B-axis stations, 8 X-Y-Z spindles and each with a tool changer magazine/arm assembly, lots to go wrong with that one but quite versatile. Then there is the hot forging side but that is a pressing matter. Manufacturing may be dying in Canada but there are a few hold outs. Thanks for the info on the threads. I always assumed BSPP wasn't compatible since the hose ends I've seen are different, the BSPP females seal using a flat face o-ring and the metric females have a internal spigot with an external o-ring to seal inside the taper of the males.
Twat u say?
I really enjoy watching this channel. I am very impressed with your knowledge and enjoy your wit. Entertaining and informative. Keep it up!
Here in the states we always laughed at the Canucks, NOW, I do it with respect! Great video, thank you for making it entertaining.

Thanks for the great video; dare I ask what AvECAD 1.0 was?
I think it was finger paints.
Crayons
Slate and stylus
Chisel and rock
1.0, fingers and a diaper
Brilliant idea thanks for your generous teaching .
nice now you are talking my language you are a man of many talents
One thing I do when working on the hydraulic system for logging equipment I build. Depending on how the machine is built it has a vaccum pump integrated into the oil tank.
If it doesn't I'll remove the breather at the top of the tank and attach a shop vac. It works great.
Also. Alot of prior don't know the type of injury that comes with hydraulics. And noone really stresses enough of the Hydraulic oil injection. It sucks. Been there. Got lucky and kept my hand.
This was awsome to watch, your a good teacher. I wouldnt be made at all if you did a (Learn Hydraulics) series ;)
Thanks for the great Classroom teachings AvE. 👍🏻
I'm usually doing the jazzhands on the confuser, but this hydrolics thing looks like the right implement to change my dentures. Laughed my ass off when he said look over there.
*unregistered version* uh-oh
Calm down, it's just Shareware! ;)
23:20 What was that expression- "ceremonial concealment of leftover bolts"? ;)
It is always good for a laugh to add extra nuts & bolts to the pile when the mechanic isn't looking.
My son, a one-time car mechanic, referred to them as 'wheeee bolts', for the sound they make as you lob them away. Joking, I hope.
I had the pleasure of running one of these a few days and that is one awesome machine
These circuits really were a fun thing in school. I always was the fastest and helped others to master the fluids.
8:33 . i was waiting to hear it bust through the ceiling as he went for the full lift . its not like that has ever haopened to me of course.
Of course.
I got my laptop stickers in Glasgow, Scotland, Thankyou!!
Great video, thanks for the hydraulics lesson!
Supreme sarcasm and vast knowledge of engineering.
Thanks
easiest way to find the pressure side is unhook the lines and start it up. every farmer knows that man
I laughed my ass off when I saw that "AveCAD 2.0, unregistered version" on a hand written diagram. :D
best way to learn scribbles on a note pad and over a shoulder of some one explaining it. Reminds me of when I was younger with my grandpa. thanks!
I love this guy! and he has a Maritool scribble pad! Hope Frank sees this!
all i know is i see at least one arm, there's talking and a machine. it's like asmr for the technically inclined with an infusion of slam poetry
2:04 I know several ladies who wouldn't mind diesel engines in their rabbits.
Do they wear plaid, combat boots and have a mullet?
Ave's vocrabutary is the real reason I watch. I just happen to learn along the way.

3 weeks of my Hydraulics and Pneumatics college class in less than a half hour. Nice!
I used to run one of those skidders for my grandpa back in the 90's and it was old as shit then. I'm amazed you found one that would still run. Ours wouldn't start with a warm engine unless you parked it on a hill and roll started it.

Another well taught lesson from Professor Bumblefruck at Ave University ,
I’ve been learning about hydraulics for 3 months. You just covered everything in half an hour. I want my money back!
Actually, I didn't cover the most important part; how this is the best school in the area for such and such and the instructors are experts in the field and how many people went on to have great careers and we're #1.
AvE that’s how I know my money’s getting wasted, that’s why I avoided the big schools like wyotech and UTI and opted for good ol’ community college. They may not have a fancy legal program, but they’ve got the best basket weaving instructors in the nation!
@@samwagner31 yes... a few years back ..20 or so.. I have 2 cousins different family's same age... 1 went to the most expensive exclusive college... the other went to the government funded tech college which had all the roughest kids in town... in there final year... non of the kids from the most expensive exclusive college had employment to start at the following year... where as the rough "dropkicks will never get a job" school every kid except 1 out of the 40 kids there had employment for the following year straight out of college.... and my cousin that that went to the exclusive college still hasn't got a job... haha
Bingys Backyard yep, in all honesty my school is pretty good. I was just joking around, if it wasn’t for the 3 months of hydraulics education, I wouldn’t have known what AvE was talking about at all. My instructors have been good about bringing companies in to give us ideas of where we want to work. I’ve gotten tons of scholarships through the school, so much so that this entire year is paid for plus I was able to get $13,000 worth of quality, name brand tools.
