Spin Casting a Babbit Bushing

- John demonstrates how HE uses the equipment available to him in his shop to "Spin-Cast" a new bushing for the rear accessory case in the Wright J-5 Whirlwind engine, using Babbit.
Most professional machine shops would be better equipped, with all the equipment needed to do this job ... but John's shop is a "one-man" operation which he has developed over the years. Bit by bit he has acquired various pieces of equipment he thought he needed and over time he has figured out how to put what he has to use, in order to create what he is after!
We hope you enjoy watching this demonstration, and we hope we might have answered any questions you might have had about how this process is done.
As always, Thanks for Watching!

Thank you for explaining the details of the spin babbitt process, Such a great video.
Thank you for taking the time to watch!!
Nicely done and explained. Nice to finally see the process. I`ve read about it and specified babbitting for a 10.5" shaft on a bridge, but never been able to see it done.
Truly a dying art. Thanks!
Like so many things, it truly IS a "dying art". Glad you enjoyed it and were able to understand as John tried to explain while actually performing the process! That is not always an easy feat to accomplish!
Your videos are just fantastic. Lost arts of aircraft construction, thanks!
Thank you for watching ... AND sharing your appreciation! We were just speaking of how these things truly are becoming a "lost" art with each passing day.
@@JNEAircraft For the past 22 years I have run a small airplane company, selling plans and kits for an airplane I designed. My job is to teach people who know nothing about airplanes to successfully build and fly their own airplane. So I know of what you speak. That is why I appreciate what you are doing with these videos. Thank you for what you do and I look forward to many more!
@@abundantYOUniverse That is awesome! You truly DO know of what you speak! Thanks for the encouragement!
Is this the bearing that failed on the original Spirit some time after the Paris flight?
We don't know which bearing failed, but there are two babbit poured bearings in the engine. The engine on the original had "static poured" babbit bearings. John "spin casted" the babbit bearings on his engine because the process makes for a far superior bearing.
@@JNEAircraft Thank you. John has an amazing level of talent, skill and dedication. He has also been doing it long enough to have made and corrected all the mistakes possible. I say that in jest as an old airline A&P. "The difference between an apprentice and a journeyman, is the journeyman knows how to correct his mistakes."
