- Babbitt Pour 2024 Un-Cut
I'm bringing you along on my biggest babbitt pour since I left the shipyards back in 1994. The two bearings are from a work boat and supply support for a five-inch propeller shaft, which was re-machined to new custom diameters.
The Babbitt material is ASTM B-23 Grade 1 Babbitt
Melting point solidus 223C 433F
Melting point Liquidus 371C 700F
Pouring temp 441C 825F
Part One, prepping for the pour, clearing the housings and making sure they mate up fine, creating the molding components and prepping the new Paragon Kiln and firing it up for the first time.
Made in China is a warning label!

Such a good teacher! I always know if Keith does it, it's well thought out. I'm retired but still tinker in my shop and it's surprising how many of your tasks can be applied to other projects. Thanks, Bravo for the opening pledge!
My dad was a machinist at american shipbuilding in buffalo. They closed in 63 . He opened his own machine shop and remember watching him pour Babbitt bearings in the 70s. Remember him calling the Babbitt high speed marine Babbitt. Your video brough back tons of memories. Thank you. MAGA.
Very enjoyable video! Thanks!!
Wow what an undertaking, looking forward to part 2.Thanks Keith
In a couple days I'll follow with the next parts in this series.
Love that opening pledge.
You never put out a boring video keep on keeping on and can’t wait for the next video
Olá amigo Keith bom trabalho como sempre!!!
thank you
Thanks, Papa Fenner for sharing
Since you have a programmable oven, could you use it to control the cooling after the pour? Would that help with the differential cooling between the housing and the babbit and reduce shrinkage issues? My hunch (based on not very much) is that it might help but not be worth the extra hours involved.
Great question, but no need because they were so close to the same temperature at pour time in seconds they matched at contact surfaces.
👍👍
Remember the wood burning stove ? HA HA HA I loved that !!
Hola ! Keiht como estas amigo ! Estaba esperando tus videos.
Bueno te mando saludos amigo espero estes bien
Thanks Keith. If I recall an earlier video where you tinned the housing before pouring and in this case not? Why different? Question not critique!
This was the bearing set I did before the tinning set. They didn't need to be tinned.
@@KeithFenner Ha Ha. If I recall the tinning job I was referring to was a job from a long time ago. Perhaps in your old shop. I didn't realize there was a current one in the works. THANKS

Is this a new babbitt job?
Or is it related to the videos from 3-months ago where ya had some pour failures?
This shows more of the failure
Where have you been for th e last 4 months?????
I have been really busy with work, side tracked by the state of our country and new changes I'm making in my shop. and a few personal side projects.
KEATH WHATS HAPPENING WITH PEARL .
Well got the shafts in Rutland and B&S grinder, waiting for my motivation and slack time to align.
@@KeithFenner OK KEATH I GET THE FINDING THE MOTIVATION BROTHER. IM PLEASE I JUST HAVE NOT MISSED ENEYTHING. AS AND WHEN . ❤️❤️
been a folle=were for years .isn't this the biggest Babbitt pour you've ever done?
At my job shop, this was the biggest. At the ship yard days, we also helped local companies that had real large rock crushers, and the pivot jaw had to be repoured every four to five years. It was about 18" bore and five foot long. We had to move the HBM outside because a Craine had to set the jaw on the table.
Bring the drama!
