This gentlemen has made more parts, fixed more broken crap, and re engineered more stuff to make it work right than the arm chair quarterbacks who had an issue have ever dreamed of. Think I trust the grizzled veteran vs a bunch of clean and soft handed numpties any day.
I was a millwright and industrial mechanic for decades. Fixed everything from ships under way to exotic multi axes cnc mills. He did a fine job. O ring kits come with a razor cutter to make perfect 90 degree cuts. Not a 45. Never ever seen a 45 used or recommended by the manufacturer. I personally have made a few thousand of them. Many many held pressure. 3500 psi hydraulic systems were common. When an o ring is needed and the machine is down, you just make one and go on to the next project. I also don't ever recall having one fail either. And I am what you would consider an expert in the use of orings. Well done sir. You can fix my crap anytime!!
I agree, I am a 30 plus year millwright as well, I have made thousands of o-rings. I will stop short on making o-rings in dynamic situations, but static o-rings like this, no problem. The only thing I do differently is I cut with a razor and use a bit of primer before the glue but other than that no problem. Done correct you won't pull that glued joint apart. Plus, as stated, why would they sell kits if its bad to make orings. Its not the kits its the people making the oring that cause failures. 👍👍👍👍
I’m an engineer who has worked for multiple pump OEMs over the years and all of them made their own static o-rings. There is absolutely no issue with doing this as long as it’s done carefully and with the proper materials.
When I use to repair heavy equipment hydraulics about 40 years ago, this is the approved way to replace o-rings on non-pressurized applications. I've never had any problems with the o-rings I made, it's a valid technique.
In my younger days I worked for a pump company as a service technician. We'd often use a splice kit for static o rings, not too much success with dynamic ones though. Good video.
Absolutely right Ralfy. I’ve been making O rings for years - there’s a lot of armchair experts out there! This practice works for scientific high vacuum applications too!
O Ring kits I used to use had a razor blade cutter for exactly square cut faces. The cut ends sat in a vee groove jig for superglueing together. They worked fine in static applications.....didn't fancy using them in dynamic situations though!
I've been a keyboard warrior for almost a 3.5 years. That means I'm an expert in everything I see on the internet. That old timer with his old hands and lack of computer skills can't possibly know what he does every single day at work while I live in a basement. Hes probably been doing it longer than my father's been alive but that's besides the point. ...stupid kids these days...
I’ve made o-rings for many a pump. Never had a problem with leaks. I make them the same way, with a square cut. The only problem I have seen with o-rings is not the o-ring, but the person installing them. A lot of installations, like a filter canister, only need to be tightened until seated, then snugged about a 1/4 turn, otherwise the o-ring gets flattened out from over tightening and it’s lifespan is dramatically shortened and leaks occur.
Worked for a company and we made all our gaskets and o-rings. Had rolls of every material we needed and the tools to cut them. Once in a while we used a ball-peen hammer.
I use these as 'belt' drives on a mini lathe. Couldn't get the size I wanted so I made a few just as in the video. They work very well, and last nearly as long as the original. I used a dab of superglue
You've cut and glued o-rings like this for a belt drive application and the don't come apart? If that's not a testament to the practice of making o-rings, I don't know what is.
If you do custom project, do you HAVE to make EVERYTHING custom around it? O-rings, seals, what else - bolts and nuts too (with what, proprietary threads)? Proper design is about using off the shelf parts if possible.
@GrandePunto8V there were serious dimensional limitations how to make it possible to fit. 6 O-rings were standard, the rest had to be custom made. And sometimes even other manufacturers are using some wierd dimensions of O-rings not readily available, so if this technique saves you weeks of time waiting for the right part or the part is no longer manufactured...
I'd bet all the people that said "you cant make an O-ring" are the same peoole that think OEM parts are always better, that think that the factory OEM oil is the only oil you should use, that think that every bolt HAS TO BE torqued to spec or it will fail, and think the tools make the mechanic.
He still didnt explain why he doesnt just buy o-rings of the correct size? If you are machining the o-ring groove, you know the size. And machining the grooves is much more work than just buying som o-rings.
I don't care about the oring, you know what I h8te? Whoever decided it was standard practise to subtitle english with ENGLISH and put it randomly all over the screen! 🤦
Refusing to accomodate standard, off the shelf components, just for the sake of it, is definitely NOT "innovative". Making everything custom and/or proprietary is a red flag. Sign of a BAD design.
If you fix something in a hurry, then yes, do whatever. But if you are so professional and master level guru in your trade, buy proper o-ring. I don't believe your job, your projects, modifications are THAT custom, that you can't machine a groove and buy an o-ring, standard size (metric/imperial), it "MUST BE" custom (there's no other way). I would never trust a company, product, service, where ALL o-rings are glued. Why stop there (at o-rings). Do you also make your own custom bolts/nuts, bearings etc.? Just for sake of it(?).

I've worked on machines where you have to make an o ring it is impossible to stretch a ring over all the other geometry on the shaft.
@sambrose1 Those are always fun..
Worked for a Cat heavy equipment dealer as a mechanic, yes they do have a "make your own glue together O ring kit".

Can't believe this video is necessary 😂 standard professional practice, everywhere, end of
Absolutely right Ralfy. I’ve been making O rings for years - there’s a lot of armchair experts out there! This practice works for scientific high vacuum applications too!
Large o-rings, like 30" X 3/8" thick, are all cord rings. These are factory made glued o-rings. The joint is polished at factory.
O Ring kits I used to use had a razor blade cutter for exactly square cut faces. The cut ends sat in a vee groove jig for superglueing together. They worked fine in static applications.....didn't fancy using them in dynamic situations though!
We had an O-ring repair kit came with different size O-ring lengths and superglue. We’re good.jamming out to good tunes too
Brilliant response!
I have been doing this for years. If you don't have it, make it! Signs of a good tradesman
Those old hands look like they got decades of experience!
Yep that’s his resume actually He doesn’t need one.
They do, with thousands of pumps built.

100 percent correct. I've been making rings for 40 years, I mostly use a razor blade, but I have used side cutters, never had one leak or fail.

Thank you for the how to , I will be making my own rings 👍🏼👍🏼👍🏼👍🏼👍🏼
Teflon O rings don't even need glue for some applications.
we used razor blades for the cut, side cutters don,t cut square.
What if you need a oring on a shaft?
i was taught at a mechanics course that making your own orings is by far the more economical way to go, and theres nothing wrong with it at all
Can u use elmers???
Did you watch the video?.....lol
@@shanleypumpandequipmentinc3857 shore did but the thumb nail looks like Elmer's
So you wouldn't want to do this for pressure areas?
If I have a guy with hands that look like that say that it’ll work. You can guarantee it’s going to work.
I personally made four custom o-rings for custom made heatblocks in my PC this way. Still holding after 7 years without a single drop.

Those hands should tell you all you need to know. This ain't his first rodeo, kids.

"my gland is leaking" That's what my dog said.
I don't care about the oring, you know what I h8te? Whoever decided it was standard practise to subtitle english with ENGLISH and put it randomly all over the screen! 🤦
I was very skeptical about using superglue to shrink an o-ring, but one day I needed one & tried.
It still works after more than 2 years.
You rookies are playing with fire
And yet, still haven't been burned.
Super glued o-rings always work short term never long term.
If people weren't innovative and thinkers we would be nowhere. Everyone seems like they are a keyboard expert, then stick to fixing your keyboard.

@@GrandePunto8VOk boomer...

We used the cord O-ring material and the Loctite O-ring bonding kit when doing stamping press repairs and rebuilds. This was the OEM required method.
That's a good idea
