I don't know what anyone else thinks, but I love watching Jon work. His tenacity and patience are part of his can-do work ethic. Happy to go along for the ride Jon. Have a great week.
@@FishFind3000McMaster sends me one every year even though I never order by calling them with what I want. I have a stack of them and just won’t let anyone near them at work.
Remember the Sears catalogs? Those were the days. They sold EVERYTHING. I like trees, but electronic catalogs suck! No way I am doing my daily business with a laptop on my lap top.
I am a heavy equipment mechanic, and I approve of this repair. This just shows me how spoiled I am with a truck crane. To do that job with an excavator just shows your level of experience. There's a big difference between operators and mechanics.
Letting elastomer seals relax after being stretched during installation is essential. A couple of decades ago, an O-ring installed on a pump shaft in a nuclear reactor was cut during machine assembly because the technician was in too much of a hurry to wait for the O-ring to relax. When the plant was pressurized, the cut seal leaked. The four or five days needed to come down, disassemble, find and fix the problem, reassemble, and heat up again cost about $3 million.
56:00 "and here we see a young excavator, assisting a full-grown excavator. The exact reason they remove and reattach parts of them is currently unknown to science"
When dealing with these huge machines, you definitely need big machines to work on other bigger machines. Perhaps the tractor could have been used instead of the other excavator. Besides that, not sure how you would do it. Guessing the cylinders weigh 500 lbs.
Kurtis would be proud of you man. He may not approve of the methods you used but you got it done with what you had available. Most people wouldn’t even attempt to do what you just did with a machine of that size.
Jon, most of the work you do single handedly at the 'farm shop' would require two people and a helper in an industrial shop or factory. Your work is mental and physical, thinking and then doing. I find myself 'talking to you' trying to help. Yeah, I know the video is days after but I can't help but want to reach in and hold or hand you a tool. I catch myself leaning in to help twist or push or pull. I and 36,511 other viewers in 5 hours say, Great job, Jon.
To make the seals shrink back to size quicker either spray it with liquid nitrogen, or you can use an upsidedown can of compressed air, or liquid gas, to freeze them and make them shrink. If you do use the can of compressed air, or liquid gas, use it outdoors and away from any flames, as the propellant in compressed air is usually buthane. Pretty much the opposite of heating them up in the oil.
I use keyboard duster. Turn the can upside down and freeze away. I keep several cans in my shop at all times just for these occasions. Also have an electric hot plate for heating oil, bearing races, etc.
Hey from Australia John, as a farm owner as well I love the channel. I have a suggestion for the name of the new excavator if you haven't named it yet. Seeing it's a Case excavator and a machine for the bigger jobs, how about Justin, as in just in Case?
Thanks for the class in seals and glands. Never had a need to work on hydraulic cylinders, but glad to learn. Now I'll always look at the hydraulics on any machines I come across to see how much service they need.
During WW2 my dad was a flight engineer on a B-17. His whole class in training consisted of farmers. He said that the reason was they could figure out how to get things done.
Have you considered seeing if a bulk oil carrier, like maybe one of the heavy equipment service companies, would come out to fill it up cheaper than buying 20 buckets of oil from Tractor Supply?
Every month gets bigger and better. Good luck getting this thing operational for under $30K! I am rootin' for ya (and watching every Friday). Great instruction on using the seal manual.
Whenever I watch your videos like this, I always wonder how many men and what kind of tooling a professional shop uses to get the job done. For doing this yourself...Amazing!
Have you considered cleaning out the hydraulic oil tank to verify that there are no metal bits down in there? While it's so low seems like would be a good time to do that, if so inclined. BTW: The way you were talking about this video at the beginning you made it seem like it wasn't exciting...dude...it was very exciting to me...this was an awesome episode! :)
Am I the only one who caught the possible reference to Curtis and Cutting Edge Engineering in Australia? That guy is always ripping apart hydraulic cylinders and rebuilding them. It couldn't have been an accident 🙂 anyway John love your stuff. I have no clue how to do half the things you do, but it's a lot of fun watching you do them, particularly alone. Good luck! Enjoy your new equipment.
No, but I did hear the reference to Kurtis. (That bloke Curtis is never around when you want him. He just keeps sponging off Kurtis' reputation anyway.)
*- This scared me, Jon, at **27:13** .* *- When the collar dropped is where I think the threads got compacted and are tightening against the "finish-threads" deep in the tube at **36:23** .*
Gotta say, 8K + shipping ain't bad at all. I know guys who pay more for cars than that regularly. Hell, guys pay more for motorcycles. Good on ya and glad to follow the project.
Considering the cost of the seals we would always make a compression ring out of steel.Just a steel ring with the id of the cilinder with a 2" taper on one side. For the sleeves we would make a cone. After a while you have a whole set for most cilinders.
as someone who used to work on heavy equipment a lot, stationary mostly (where the cylinders you're working with are actually on the small side compared to what i'd have to fight with, think 12" barrel and 15' stroke as an average)...as i watch you do the hokey pokey trying to maneuver large heavy cylinders into position it just reminds me of all the incredible effort i had to go through to get BIG STUFF into SMALL PLACES with the wrong equipment, a pile of chains, wood, porta powers, and bigass prybars - and by myself a lot too! thankfully i was able to move my career into a technical field and save my body from worse injury. i wish i was able to share some of my tips with you to save you the headaches...but you figure out a way that works eventually in the end anyway. i'm glad i found this channel, it's like cathartic nostalgia HAHAHA
I work in hydraulics, and watching you pile up a cyl is so rewarding. Keep given er eh next time, throw that glan into the lathe and polish everything and the piston as well and wire wheel the cylinder threads and fully clea out the cylinder
Jon, I love watching every one of your videos... Like someone else said in your last video, I'm starting to get heavy equipment envy. A couple of highlights from this video that I loved you keeping in there... 27:55 - The pop and "what just happened" followed by... 32:36 - "I'll lightly screw this in this time and..." *splat* "I love this job..." 44:58 - Jon getting manhandled and hip tossed by the cylinder
I have no advice. No suggestions. You do what you do and share with us. I have enjoyed all of your videos never want to see you fail or have problems. What really makes my day is seeing you solve a problem that I can't see an answer for. That is so cool. THANK YOU FOR ALL THAT YOU TEACH US.
I like to put a zip tie around the outside of stretched seals to help them go back to original size in a timely fashion. Keep up the great work. I'm always happy to see you upload.
When I was repacking cylinders, we would take an old antifreeze jug and cut strips out of it, wrap it around the piston seals and then put together a couple of screw clamps for the right diameter to act as a ring compressor. Worked great
Let them have their wining Jon, from my perspective, you are the smartest well-thought out rigger I see on this platform; learning from you every time, if not technical than logical, you are a keeper in my sublist, take care and thanks for the effort!
Thanks Jon, great videos on this old behemoth. Don't forget to order the seals for the opposing cylinder on the boom; you know that middle seal is disintegrated and ready to dissolve into the hydraulic filters soon!
Your adventures are like a role playing game. Start out with small equipment and then use it to help you get bigger equipment. That must be what makes this channel so fun :) Who would have guessed you would use a skid steer and a mini excavator to rebuild a giant excavator..
a Little Giant ladder is superior to those thin aluminum bone/neck breakers, the newer ones have adjustable feet as well, making them very stable on uneven surfaces. I bought my 2nd 5" extendable for less than $100 at Lowes, (sold the first one to my company years ago) it cost me $350 used. the 2nd one is easier/safer than the first one. these are ladders that will outlive you, and most important, keep you in one piece.🤪👍
It always amazes me you don't oil your seals and rings when installing them. Maybe I just like fiddling with oily seals... Love these rebuilds. Always nice to see someone who does it right instead of convenient.
Jon, here's a thought on the hose fittings. See what it would take to swap the ends on the hard pipes to JIC. It may be a challenge, but in the long run it would be something to do on an as needed basis when a hose needs replaced.
Hey John i Love your Videos one Special Tip from me do the Piston overnight in the refigerater or use coolspray then IT goes better sorry about my english greetings from germany
maybe you need to find a thin plastic shim to not stretch those seals so far and not screwdriver. Slide the ring over the shim (you can use that clear plastic stuff you had as a shim) till it gets where u want it, then remove the shim and it will go into place. Alot like the process of installing pistons with rings. It will keep from having to stretch it over each section.
Glad to see the seals back . So the glans on the end of the rod lead to an impressive ejackulation of hydrolic oil . Well done Sir . They make aluminum ladders rated for 350 LBS that feel like you could park a truck on .
"Jon Gets His Groove On - time after time!" ...glands will be greased...there will be seals..lots of seals ...tight seals ... unfortunately at least one seal was harmed in making this production...opening in theatres June 1 - don't miss it!
You're not a 'bad TH-camr', Jon. I found this very interesting. The width and breath of your posts keep me highly interested. Keep doing what you're doing. Please and thank you.
The best hydraulic shop in VA is Precission Hydraulic in Hollins VA, north east side of Roanoke. See Josh They actually make hydraulic cylinders there, can rechrome rods, weld barrels, repair hydraulic motors/pumps and valve bodies
It’s really nice to have a machine this size. We have one at the farm too, and we like you bought an old one. I suspect yours is quite a bit newer or less hours on than ours tho as we struggle a bit with “sloppy joints”. It was quite egged out so actually had to weld on new ears on the boom. That was a lot of work. Ours is a Norwegian made Brøyt so it’s nice to preserve some history too. But boy I feel you when you say it’s hard to source parts. Imagine for a locally made machine like we have. You basically have to make the best out of what you have. Strong machine tho and does the job like a champ!
It's not so much as to whether you got ripped off, it's more how many times do you need to use the machine to feel like you've done $11.7k of work with it. But then again, none of the financials really matter. You wanted, could afford it, so you bought it 🙂 That's the system we live in, and yet we often try and quantify our decisions with financials. You rebuilt your wheelbarrow because it was the right thing to do. It happened to stack up financially, but I don't think that's the best reason to have done it..... You did it. That's the best thing.
Well John, you've done it ! You're playin' with the big boys now! (Cheers for the guys at the Hawkins Graves Hydraulic Shop 😘). And no, you didn't get ripped off -- think of how much you've learned, how much you've accomplished AND you have a working dozer that would have cost you $100 K. Once fixed, it will work for you for decades -- AND if you wanted to, you could sell it as a truly functioning dozer, with VIDEO proof of its repairs. No worries, my good man! Yes indeed, you're playin' with the big boys now ! And winning !
Jon, play it safe. We would much rather cheer when she comes to life than groan when she fails. Personally, I get a real pleasure out of seeing you succeed. To me, it's like the little man against "the machine." 🤪
Great and simple explanation of baby steps of understanding Seals ! Who knew that we would learn how simply things could possibly be when you have confidence too understanding Seals !
John, my son just bought a 1985 CAT 215 excavator with 11,000 hrs and manual thumb and weighs 36,000 lbs he paid 12,500 for it. It works great and has minor leaks and a small amount of blowby out of the oil fill. Your machine was cheap for the amount of work you will get out of it. You will probably be able to sell it for way more than you paid if you keep it up like you do. Great videos BTW.😀
12:00 That seal is burned due the socalled "Dieseling or Diesel effect". When air gets inside a hydraulic cilinder either due not propably bleeding, or due leakage arround the rod, air get inside the cilinder. This air then create airbubbles (that contain oil vapour) and these airbubbles then get compressed by the high oil pressure, they become very hot to a point this oil vapour gets ignited like in a diesel engine and burn the rubber seals. These seals start to leak more and more, and more air gets inside the cilinder and the entire proces repeats itself and the seals get totally ruined.
Thanks for explaining this, I wondered why they looked that way. I make sense now, they probably just run machine low, added oil when it wouldn't go no more.
Yeah, I was thinking the same thing. Next thing you know Jon will be getting toys for his puppy dog to play with during intermission. If Jon keeps buying bigger and bigger stuff to work on he is going to need a shop like CEE's to get er done!
Another great video, I love Friday nights. You did well to manage those cylinders on your own, hat off to you. Have you ever thought of buying your oils in IBC , it works out cheaper, but you need a stand for them to make it easy to decanter the oil into drums or jug. Can't wait till next Friday, have a great weekend.
That catalogue didn't have an entry for Fur Seals. 😲 When fixing the hole in the chrome, just remember that it's *your* rod so you can _polish it as fast and as often_ as you like. 🤭 I imagine that the $7,700 you paid for it wouldn't even cover the cost of a hydraulic fluid fill after putting clean fluid in the repaired cylinders. 🤔 I think you got a bloody bargain; a bit like the skid-steer you purchased and found the unknown issues with it when you got it home (and I was not being sarcastic about the skid-steer adventure). If the wonderful people out there in TH-cam land look at what you have paid for the old industrial equipment you have acquired and then looked at the prices for second-hand ones that had fewer issues then I think they'll find there was no way you could have justified the cost of the latter machines. The really big bonus you received is the experience and knowledge you have gained fixing the machines up. You can't go to a store and buy five midrange figures ($$$) of experience off the shelf. Man you have won *big time* on your purchases in the 3½ to 4 years that I have been following your videos. Far king *MASSSIVE* wins there Jon. 👍👍 Hope you can claim buying, repairing and running these _essential farm tools_ against the farm income. You sure deserve a break in that direction IMO. 🤑🤑🤑 You could have asked Jesse Muller if you might have -borrowed- hired his low loader and moved _Mr Beast_ yourself. Imagine having Mr Beast when you were digging out your neighbour's pond.......... 😍😍 *Thank You* for the videos Jon. 👍👍
Jon spent $800 on the PARTS. You think a hydraulic shop is going to sell those at cost? Add the labor and it would have cost him $5K. Jon doesn't yet know what other major thing the machine needs. He first needed to stop the bleeding before he can even evaluate it. His way, his YT video paid for it, and we get great entertainment. Your way is only for a rich and lazy man...that just sucks.
As you try to repair the line that is brazed, is there a way to weld on a new more modern fitting so you can use a line that can be purchased? Just a thought... not a mechanic here. :) Awesome video. Thanks for having us along on the ride.
great stuff, Jon, really enjoy your efforts. Please get a used electric hoist. As a former big rig mechanic, I can tell you it will cut your physical effort on a project by 50%. Think about it: you use power drills, power saws, power excavators, power fans, etc.. but have a hand-operated chain hoist... ?? Save your energy. Anyhoo, thanks for all the energy, time and talent we all enjoy so much! - Mark
The problem you encountered at time 27:56 is a direct result of applying way too much grease to the gland. Channel is growing great now. Been watching from the early days. Great skill set. Can't wait to see what you dredge out of the pond.
Why not hang your chain hoist from the bucket? Then use that to lift the cylinder. Then maybe you’d have 360 access? Great content as always. Don’t mind the haters you work with what you got.
Hi @Taskarnin, I was thinking the exact same thing,having some experience in “crane rigging” in my youth. I’m sure if we were there in the real, the reason is probably clear. IDK? Hopefully he’ll fill us in. ✌️
Oiling your rod, greasing the gland and ejaculating fluid 😮. I didn't think YT allowed this type of content. Great educational videos Jon, thank you ❤.
I feel like to see someone who does this stuff as amateur as I get to see it from both sides when I watch cutting edge engineering and then your channel keep up the work. Not everybody has the big huge tools or the money to buy that stuff. You use what you got to get the job done
Pretty soon, "Hey guys I just bought this locomotive! I don't need it, but it's great!"
LoL 😂😂😂
Come on, don't pull your punches. Let's get really ambitious. Like maybe an Abrams tank. Perhaps the Navy has an aircraft carrier for the pond...
Well they do have the 1218 just sitting up in Roanoke not doing anything. 😂😂😂
Well I dont know . Maybe a track around the perimeter to haul firewood to the boiler . Think of the tractor hours he would save.

Agreed! And I swear he never gets upset. The closest I've ever seen him to cussing is throwing out a joke of some sort.
Send him to Wash DC and have him fix those seals!

The way this channel is progressing, I expect your next project to be a Liebherr R 9800!
Glad to see the seals back . So the glans on the end of the rod lead to an impressive ejackulation of hydrolic oil . Well done Sir . They make aluminum ladders rated for 350 LBS that feel like you could park a truck on .
John, I like that you can apologize when things did not go as planned and you made a miss take.
Great job, boss , it's a pity CUTTING EDGE ENGINEERING couldn't visit you over there and help out . LoL ❤
This is one of those several beers after jobs. Been there but on much, much smaller cylinders
It’s a good day when farmcraft post a video
"Jon Gets His Groove On - time after time!" ...glands will be greased...there will be seals..lots of seals ...tight seals ... unfortunately at least one seal was harmed in making this production...opening in theatres June 1 - don't miss it!
You're not a 'bad TH-camr', Jon. I found this very interesting. The width and breath of your posts keep me highly interested. Keep doing what you're doing. Please and thank you.
In europe these machines were known as Poclain 170B. Poclain was a french brand taken over by Case at the time.
thanks John, really enjoyed this! Nice to see the shout out to Curtis at CEE!
Thank you for taking us along I learn a bunch
The best hydraulic shop in VA is Precission Hydraulic in Hollins VA, north east side of Roanoke. See Josh
They actually make hydraulic cylinders there, can rechrome rods, weld barrels, repair hydraulic motors/pumps and valve bodies
this is why it costs so much to have this work done by Shops. It takes time and the right tools. Good on you for doing it yourself
It’s really nice to have a machine this size. We have one at the farm too, and we like you bought an old one. I suspect yours is quite a bit newer or less hours on than ours tho as we struggle a bit with “sloppy joints”. It was quite egged out so actually had to weld on new ears on the boom. That was a lot of work. Ours is a Norwegian made Brøyt so it’s nice to preserve some history too. But boy I feel you when you say it’s hard to source parts. Imagine for a locally made machine like we have. You basically have to make the best out of what you have. Strong machine tho and does the job like a champ!
It's not so much as to whether you got ripped off, it's more how many times do you need to use the machine to feel like you've done $11.7k of work with it. But then again, none of the financials really matter. You wanted, could afford it, so you bought it 🙂 That's the system we live in, and yet we often try and quantify our decisions with financials. You rebuilt your wheelbarrow because it was the right thing to do. It happened to stack up financially, but I don't think that's the best reason to have done it..... You did it. That's the best thing.
Well John, you've done it ! You're playin' with the big boys now! (Cheers for the guys at the Hawkins Graves Hydraulic Shop 😘). And no, you didn't get ripped off -- think of how much you've learned, how much you've accomplished AND you have a working dozer that would have cost you $100 K. Once fixed, it will work for you for decades -- AND if you wanted to, you could sell it as a truly functioning dozer, with VIDEO proof of its repairs. No worries, my good man! Yes indeed, you're playin' with the big boys now ! And winning !
That was a good tutorial on getting seals for older machines. I may just have to get that catalog
Yeah, it’s easier than I realized. You just need to be able to measure accurately. A pair of groove calipers is a must.
Scrap yard Sally part 2. I have been looking forward to this since last week.
Jon, play it safe. We would much rather cheer when she comes to life than groan when she fails. Personally, I get a real pleasure out of seeing you succeed. To me, it's like the little man against "the machine." 🤪
My grandson spends all of his time gaming in his room. He has no idea what he's missing doing a project like this!! Thank you, Jon!!❤
That's creepy, but then I'm an old guy.
Your trick on installation solved a lot of headache for me in other projects, not to mention the sense of humor @12:04 LOL
Jon what you achieve with the equipment you have & on your own is amazing 👏👏👏🇬🇧🇬🇧🇬🇧
"It's not Cutting Edge Engineering". That was a good one. :)))))))))))
Great and simple explanation of baby steps of understanding Seals ! Who knew that we would learn how simply things could possibly be when you have confidence too understanding Seals !
I went ahead and gave each of the seals a fish.
John, my son just bought a 1985 CAT 215 excavator with 11,000 hrs and manual thumb and weighs 36,000 lbs he paid 12,500 for it. It works great and has minor leaks and a small amount of blowby out of the oil fill. Your machine was cheap for the amount of work you will get out of it. You will probably be able to sell it for way more than you paid if you keep it up like you do. Great videos BTW.😀
For o rings we always used waxed nylon cord, just make a loop and slide it around in a circle.
12:00 That seal is burned due the socalled "Dieseling or Diesel effect". When air gets inside a hydraulic cilinder either due not propably bleeding, or due leakage arround the rod, air get inside the cilinder. This air then create airbubbles (that contain oil vapour) and these airbubbles then get compressed by the high oil pressure, they become very hot to a point this oil vapour gets ignited like in a diesel engine and burn the rubber seals. These seals start to leak more and more, and more air gets inside the cilinder and the entire proces repeats itself and the seals get totally ruined.
Thanks for explaining this, I wondered why they looked that way. I make sense now, they probably just run machine low, added oil when it wouldn't go no more.
I'll wait patiently for the next video. It's always worth it.
🤣🤣🤣 It's not "Cutting Edge Engineering" I'll bet'ya Curtis got a kick out of that analogy. Great job anyway Jon.
Yeah, I was thinking the same thing. Next thing you know Jon will be getting toys for his puppy dog to play with during intermission. If Jon keeps buying bigger and bigger stuff to work on he is going to need a shop like CEE's to get er done!
Another great video, I love Friday nights. You did well to manage those cylinders on your own, hat off to you. Have you ever thought of buying your oils in IBC , it works out cheaper, but you need a stand for them to make it easy to decanter the oil into drums or jug. Can't wait till next Friday, have a great weekend.
Lol - I felt the urge several times to hand you tools - especially when you were up on the big machine.
That catalogue didn't have an entry for Fur Seals. 😲
When fixing the hole in the chrome, just remember that it's *your* rod so you can _polish it as fast and as often_ as you like. 🤭
I imagine that the $7,700 you paid for it wouldn't even cover the cost of a hydraulic fluid fill after putting clean fluid in the repaired cylinders. 🤔 I think you got a bloody bargain; a bit like the skid-steer you purchased and found the unknown issues with it when you got it home (and I was not being sarcastic about the skid-steer adventure). If the wonderful people out there in TH-cam land look at what you have paid for the old industrial equipment you have acquired and then looked at the prices for second-hand ones that had fewer issues then I think they'll find there was no way you could have justified the cost of the latter machines.
The really big bonus you received is the experience and knowledge you have gained fixing the machines up. You can't go to a store and buy five midrange figures ($$$) of experience off the shelf. Man you have won *big time* on your purchases in the 3½ to 4 years that I have been following your videos. Far king *MASSSIVE* wins there Jon. 👍👍 Hope you can claim buying, repairing and running these _essential farm tools_ against the farm income. You sure deserve a break in that direction IMO. 🤑🤑🤑
You could have asked Jesse Muller if you might have -borrowed- hired his low loader and moved _Mr Beast_ yourself.
Imagine having Mr Beast when you were digging out your neighbour's pond.......... 😍😍
*Thank You* for the videos Jon. 👍👍
Step 1. Remove Cylinder
Step 2. Take to rebuild shop
Step 3. Write a check
Step 4. Install rebuilt cylinder
Step 5. Enjoy a beer or cocktail
Jon spent $800 on the PARTS. You think a hydraulic shop is going to sell those at cost? Add the labor and it would have cost him $5K. Jon doesn't yet know what other major thing the machine needs. He first needed to stop the bleeding before he can even evaluate it. His way, his YT video paid for it, and we get great entertainment. Your way is only for a rich and lazy man...that just sucks.
You got a steal on this machine sir., nice work.
No steal, he hasn't gotten into the carriage bearings yet, the pumps, and all the rest of machine. With time and money, will see.
As you try to repair the line that is brazed, is there a way to weld on a new more modern fitting so you can use a line that can be purchased? Just a thought... not a mechanic here. :) Awesome video. Thanks for having us along on the ride.
It was a lot of work. I'm watching you a lot of time and as far as for my glance it was the hardest work. Good job!
great stuff, Jon, really enjoy your efforts. Please get a used electric hoist. As a former big rig mechanic, I can tell you it will cut your physical effort on a project by 50%. Think about it: you use power drills, power saws, power excavators, power fans, etc.. but have a hand-operated chain hoist... ?? Save your energy. Anyhoo, thanks for all the energy, time and talent we all enjoy so much! - Mark
come to think of it, don't you have a portable winch? you can use it as a hoist...
Necessarily is the mother of invention!! you have unique ways to get work done. I really enjoy your content. THANKS
The problem you encountered at time 27:56 is a direct result of applying way too much grease to the gland.
Channel is growing great now. Been watching from the early days. Great skill set. Can't wait to see what you dredge out of the pond.
Why not hang your chain hoist from the bucket? Then use that to lift the cylinder. Then maybe you’d have 360 access?
Great content as always. Don’t mind the haters you work with what you got.
Hi @Taskarnin, I was thinking the exact same thing,having some experience in “crane rigging” in my youth. I’m sure if we were there in the real, the reason is probably clear. IDK? Hopefully he’ll fill us in. ✌️
Impressive job
*we treat it by straightening and re-plating it*
I just love this channel. Thank you for the wonderful knowledge.
Oiling your rod, greasing the gland and ejaculating fluid 😮. I didn't think YT allowed this type of content. Great educational videos Jon, thank you ❤.
Lightly Poached Seal. Mmm. Great content Jon. Lovin it.
Regarding the discussiom of banana scales in the beginning: isn't it more than one imperial measuring system? Like UK and US gallons and so forth?
John, your work-a-rounds are a work of art.
I feel like to see someone who does this stuff as amateur as I get to see it from both sides when I watch cutting edge engineering and then your channel keep up the work. Not everybody has the big huge tools or the money to buy that stuff. You use what you got to get the job done
