Steve also has a cool podcast called "A podcast of unnecessary detail" A series of construction videos will come out on this channel showing all the machining steps to create your own Kingsbury tilting pad air bearing. Send me an email and introduce yourself if your interested in the construction drawings.

Incidentally, this is how hard drive heads 'fly' over the disk surface.

Great video! Can't wait for the build video.
-
Oh SHIT this is a collab with Steve Mould, talk about worlds colliding, so cool man
-
After working 43 years as a physicist, I still find this stuff fascinating.... I am now a amateur machinist .. great to see your skills combined with Steve’s
-
Linked here from Steve Mould's video, didn't realize I was already subscribed to this channel.

Talk about a surprise collab. Love to see it
-
That is an absolutely fantastic piece of very old engineering. As a point of reference, there has been a 2.25 ton K/M bearing in constant use... since 1912, with virtually no maintenance. It has an estimated life of 1300 YEARS. Amazing stuff.

Thanks. The one thing I wished Steve would have done, was, spend more time on the unit. This you did for him. I love custom fabrication, and people with talented hands.
-
Thanks for continuing to educate people, this kind of work is required to keep a smart, engaged, and enthusiastic next generation.
-
Well, talking about that intro.. I really do apreciate you sharing all of your knowledge! I have learnt a lot from purely observing what you do and how you do it, I don't do metal working, rather woodworking, but still I learn a lot about layout, measuring, cutting tools etc (a lot more as well!) Cheers :)

Great stuff. I work in the Hydro Power industry, and we have similar bearings (oil not air, and 100x bigger) that support more that 600 tons while rotating 300+ rpm. Great to see this demo and teach others the power of hydrodynamic bearings. The machine shop guys get mad when you ask to get a 20 inch bearing pad to 100 micron flatness tolerance, but we get 150 (0.5 mil).

You know what, it is my first time here. Thank you for that introduction.
-
Thanks Steve Mould, I like this guy already!!!!!
-
This would be an awesome science fair project for a kid!
-
The engineers and scientists of the world would be hopeless and helpless without people like you who can create the precision tools they need to do their work. Don't sell yourself short.

This is a cool demonstration of a hydrodynamic bearing. Same principle that prevents metal to metal contact in the rotating parts in an engine. It's NOT oil pressure that does it, it's the hydrodynamic bearing effect that keeps the metal from touching even with hundreds or thousands of pounds of force.
-
I have used some air lift rotary tables on the big HBM's before and you can move parts weighing 20tons or more with just your fingers. Pretty cool!
-
Really cool. I’m a machinist for Kingsbury. We use a very similar model to demonstrate the principles behind our thrust bearings to customers. It was nice to have this video to show my wife what these bearings do on a fundamental level.
-
I honestly have no clue what that would be used for but it is probably the coolest thing i have seen in awhile.
-
Here from Steve Mould's channel. I think I am really gonna enjoy your videos, I enjoy machining videos and science so this should be a great combination. Also sounds like you have an amazing job, building things for scientific test seems like it would be challenging and exiting.
