Excelent video!

Very nice. I have an application where my static rod will be between two sizes. I.e a 113 Buna N O ring will have a 9% stretch but a 114 will have about 0.5%. The 113 feels about right using a 50 durometer i.e soft O ring. The application will run at up to 230F. I think a 113/50 is about the best choice in this application.

Great Video!

This is a really great video. A few years ago, I had to design a master cylinder and it took weeks of going through textbooks to finally land on the lifersaver that was the Parker handbook. (Not an ad) Pretty much everything important was covered here and if you need more information you know the terms to look up.

Thanks!

Fuckn annoying American standard video . The whole world follows iso standard . So make an iso video . Stupid American fkups. Follow the whole world . You aren't special.

Can you remaster the found one

Very interesting. I’m subscribed and look forward to watching more videos from you.

can you please help me with name of the book shown in the video.

Thanks for sucha useful, no frills, no bs vid

I am using a 12mm bolt and nut for the installation of tow hitch receiver for my bike rack. Is it not a good idea to use 14mm washer on a 12mm bolt? What is that 2mm internal clearance going to cause? 14mm washer is what's currently available, so i used it. Should I remove and replace it with a 12mm instead?

This was very helpful. Thanks

what is the name of the lubricant?

super

I'm glad they made these videos quiet enough so my engineer leads won't hear what I'm doing. Great content, thank you!

If you stretch an o ring, the diameter shrinks but what if you compensate for this by getting bigger CS ?? is that possible

Sure, a manual tool will provide a "more accurate" measurement "faster" than a CMM that can run a program with no operator intervention and is accurate to 6 decimal places... keep on telling yourself that. Are manual metrology tools valuable? Absolutely. For one-offs and prototypes, or spot-checking features, there's absolutely value. For production runs, even short runs at a job shop, the CMM is king if the shop can afford one.

Thank you guys so much for the free documents❤❤

this video contains more than my 7 years in school

Blu tac is good for securing ring gauge to table

Would be nice to see some content on precision measuring angles. I'm wondering what instruments a mechinest would use for this outside of a protractor and square. Great content tho. Super thanks

You create fantastic videos , my only one critique is I sometimes struggle to take the info in due to the speed you talk. If you could slow it down just a smidge it would give time to fully absorb what is being said. Keep it up I look forward to the next one.

Nice

What air compressor are you using??

This is great. I needed advice from real engineers.

Everything was clear until I came across those barbarian units.

Nice explanation

How does interference fit work- like , how does it make it permanent? what's stopping it from coming apart?

Please come back

Me new student.

Fantastic video! I make stuff. This organized information is priceless.

Are y'all still planning to release the video on GD&T Position tolerance? These videos are exceptionally clear!

I really would love to see more :)

Good video I like how you use easy to use information like the parker o-ring handbook. Would you be able to explain the actual squeeze listed in the parker o-ring handbook on the page where it has the width and depth. The cross-section minus the gland depth is different from the actual squeeze? That is the bit I don't understand.

Really helpful.

All I can think of is sex

Is there an international version of this where people don't say thou and micron? Is the micron on the same base as thou or is it supposed to mean micrometer? I only want meter as base unit.

Designed by George P. Burdell… One helluva engineer!

I am very happy that we have ISO and DIN standard, so everyone here has to do it that way an not draw how the machinists "love it"

heck yeah

Thank you, such valuable information!

Feb 1986: The president of the Parker Seal Group today said the rubber seals manufactured by his firm for joints between shuttle rocket booster fuel segments met all specifications. Pat Pastryk said neither NASA nor the company that built the solid rocket boosters had ever questioned Parker about its product used in the space shuttle program. Speculation on the cause of the Jan. 28 explosion that killed the seven Challenger astronauts has centered on the joint between the lower two of four fuel segments that made up the ship's right-side rocket booster. NASA film shows a plume of flame erupted at or near the joint, which may have triggered the explosion of Challenger's external fuel tank. Pastryk emphasized in a news conference that his company only produced the material used to make the giant O-rings. 'The O-ring is a component of a complex seal arrangement,' Pastryk said. Parker's Berea, Ky., plant produces 12 -foot sections of cord about one-quarter inch in diameter. Three pieces of the cord are spliced together by another company, Hydra Pac Inc. of Salt Lake City, to form the O-ring. The O-rings are part of a complex joint design and provide a barrier to prevent hot gas or flame from burning propellant inside the booster rocket from escaping through the joints between fuel segments.

THIS IS THE MOST EDUCATIONAL VIDEO I HAVE EVER WATCHED ABOUT METAL PARTS. - EXCELLENT AND THANSK FOR SHARING KNOWLEDGE...! <3

“A lot of new engineers really struggle with making drawings, especially because most universities do an awful job teaching the concept” - 10:10 Agreed! That was one of the largest problems that I had to deal with in both my design and manufacturing work. I received drawings all the time from “specialized” shops full of new grads that had no concept of what a good drawing was supposed to be like. After phoning them, they would say “just do your best to meet the dimensions”… but they didn’t realize that conflicting dimensions will make the part inoperable or not function correctly. Anyways, this is an awesome video! Thanks for producing it. Looking forward to diving into more of your work! 👏

Shame you guys don't do videos anymore. These are great.

Hard to hear and understand one of the narrators!
