Keith, the way you used the damming material on the faces of the rings made perfect sense. I have never poured babbitt, but I've done some DIY in sinks, and it seemed to work just like plumber's putty on the drain. Thanks, it is always fun to have "coffee with Keith"!
Great Job Keith. Watching you pour the Babbitt, you look like a complete natural doing that. Really nice job on the mandrel and disc. Thanks for sharing the process. Have a great week. 👍🇺🇸👍
years ago I worked with an Old Fella who taught me how to pour Babbitt Bearings whole not split like your doing. He would use oxy acetylene torch and made it smoke heavily then coat the shafts of the presses we were working on with that smoke. we build dams with clay and pour the babbitt. resulting in perfect clearance's no wobble or chatter smooth operation cup type wick oilers were used afterwords in some cases. this was back in the 1970s and he was 70ish I was early 20s
As always, thanks so much for making. Big huge thank you to you who produce the site creatively through perseverance and brains. It enables me to spend some time to learn new things, apply new things, and do all my work the way you inspire me.
Fantastic work on this repair/restore. This project is really moving at warp speed. I guess retirement agrees with you. Thanks for sharing. Love your videos. (patiently awaiting the stoker engine. 🙂)
I saw another RUclipsr use regular silicone sealant when pouring/vacuum casting bronze and copper. He used it to seal the form to the vacuum. It gets really hot and the silicone burns but he only needs it once. I suspect you could use the same idea for the face of the mandrel spacers.
Like other subscribers have said "You make it look easy". I noticed one thing different from other pours. The mandrel bearing surfaces were not coated in soot and it didn't seem to effect the removal of the mandrel form the pour. My question is how do you know when to coat and when not to? Thanks for the video. KOKO!
Is it possible to wrap a wire around the mandrel to create a channel for oil, especially in the lower half of the bearing shell? You cold possibly flatten the wire a bit in a ring roller or similar equipment to make the channel wider and less deep. It would have to be tight on the mandrel in order for it to be pulled out of the babbit at the end of the pour.
Someone asked about gaskets instead of damning material. I suspect flat gaskets would not fill and seal the rough casting as well as the damning material. Also the hot Babbitt would burn the gaskets out leaving a gap for the molten material to flow out.
Keith, would there be any advantage in using the laser cutter and making shims out of gasket material instead of the mold pack? Like the shims you made for the caps on the larger drum.
That's an idea. wonder if you're suggestion would work and if so the ultimate pro's and cons. Anyways, being a tight arse myself even just as much with other peoples money and resources too...! I got to say that the minimal babit material he used this time made me really happy! I know he re-uses most of it anyway so this new set up won' change how much he needs per job. But it still albeit 'temporarily' soothes my own niggle issues, I got to confess on that one.
Do you check straightness of the mandrel before pouring? While I own a vehicle with poured bearings (an old Ford) I'm a modern engine guy so I always assumed things like this got line honed after pouring.
quick question... if the babbitt bearing is a little bit tight... can you just put some lapping compound in there and work it for a minute or is scraping a better option? will lapping compound embed into the babbitt?
Yes, he uses Fahrenheit like 99% Americans. In slang language are called "degrees Frankenstein" 😅 Technical people who use Celsius will usually say degrees Celsius or degrees centigrade to avoid confusion.
@@ruben_balea Hey Ruben, we "slang" Americans put men on the Moon and won WW2 with our Imperial system so we don't need any snide remarks from some "Metric Snob" !
@@garybrenner6236 Hey! Calm down! The American RUclipsrs themselves are the ones who call Fahrenheit degrees "Frankenstein degrees" in their videos to look funny. I have nothing against the imperial system which I use a lot for thread sizes and pressures, I just said that in case the OP hears the "Frankenstein" thing in other videos and wonders what that means.
I would be concerned about trash getting into the bearing surface and causing damage if he leaves the keyway open. I agree with brazing that in solid and machining it to size.
why are you using oil and not food grade grease? won't that need to be cleaned off 110% before using the mill ?? I assume it will be used once in a while ?
How do you make sure babbit bearings are holding shaft square to a big wheel? This is something about scraping that was always confusing for me ,how do you keep things parallel and square.
@@hobbiesrus That doesn't answer his question at all.... He is asking How Keith knows if the gear will mesh correctly with the internal ring gear (not too far down not too far up), just having used a shaft and rings which are centering the bearings in the middle of the casting. The real answer here is, i honestly believe he just assumed its in the center. This would have been the perfect job for 3D printing.. Print a shell put it in and check alignment with the internal ring gear.
@@FireGodSpeed This isn't a precision machine where tolerances have to be held to the .001". He isn't going to waste time 3D printing stuff to get the clearances and alignment just perfect.
@@tsmartin Honestly people like you shouldn't comment. Looking at my comment, nowhere did i say it was "precision" "tolerances to .001%" "Just perfect" I literally said and i copy and paste "How Keith knows if the gear will mesh correctly with the internal ring gear (not too far down not too far up)". You are 100% wrong there are* 2 tolerances which could make it or break it, it can be 10-20-30 thou maybe even more higher but 30 thou LOWER could make the gear hit the bottom of the teeth of the internal ring gear and the side tolerance if he was 20-30+ thou to far to the right (on the right one) it could also prevent the gears from meshing entirely.
"Oversize for shrinkage"? When the babbit shrinks when it cools and the mandrel expands when it's hot the finished bearing will be pretty sloppy won't it?
Would love if you showed this mill in action once it's done. Great progress, you make those bearings look easy.
Keith, the way you used the damming material on the faces of the rings made perfect sense. I have never poured babbitt, but I've done some DIY in sinks, and it seemed to work just like plumber's putty on the drain. Thanks, it is always fun to have "coffee with Keith"!
Was thinking the exact same thing.
Thanks Keith for the video. One more step along the way. I hope we get to see the mill run when it all through.
I hope sometime in the next Decade we will get to see the Stoker Engine!
Great Job Keith.
Watching you pour the Babbitt, you look like a complete natural doing that.
Really nice job on the mandrel and disc.
Thanks for sharing the process.
Have a great week. 👍🇺🇸👍
You used to put soot from the acetylene torch on the pouring mandrel to help it separate. Why didn’t you do that on this pour?

Kieth has the nicest dude award
Amazing! He put back together the two halves of Babbitts' shaft!
Well I’m power binging got some out of order but it is easy to fill in the blanks and all. Thanks for sharing.
Fantastic. Thanks for your willingness to invest the time to make these vids.
Thank you. I thought you would have a tough time getting the mandrill out because you didn’t apply the carbon. Not to worry it all worked out.
Enjoyed the slightly more aggressive than usual speeds and feeds lol. Bearings came out really nice!
As always, thanks so much for making. Big huge thank you to you who produce the site creatively through perseverance and brains. It enables me to spend some time to learn new things, apply new things, and do all my work the way you inspire me.
It take a tremendous amount of skill to make it look so easy.
not just the machine work but the video as well.
The one man shop does a great job.
Very well done. You have demonstrated that a one man shop can do the job as long as you have the right tools.🙂🙂
I am enjoying the work on the bearings, You do some very nice work.
Hey Keith! Thanks for sharing another great installment on the refurbishment on the monster cane mill. It is progressing quite nicely. Cheers!
I'm really enjoying this series. I've watched you repair the little ones, in the case of most things, size does matter.
Cool babbit pouring 😊😊😊
I always look forward to your videos! Thanks Keith!
This series of videos make a great drinking game. Just take a shot every time Keith says Babbit!! 😂❤
Thanks for another great video.
Really appreciate your work and learning from you
Thank you Keith!
Looking forward to seeing this working.
Very good video. Excellent. Thank you.
Fantastic work on this repair/restore. This project is really moving at warp speed. I guess retirement agrees with you. Thanks for sharing. Love your videos. (patiently awaiting the stoker engine. 🙂)
Quite similar to an earlier episode. Well done.
Looking good Keith, nice pour.
great job.
keith Nice job on the Bearings !
Coming along nicely Keith.
Keith always has two speeds, too fast and way too fast LOL Thanks for a great watch, I liked this one !!
I'm glad you are finally working on a more accessible area and a smaller shaft. The poor turned out great, Keith.
Good job, Nice
Thank you for sharing. Great job Keith👍
Watching for years! Thanks Keith!

Lost art! Greatly appreciate this content.
thank you
Thank you for another Great video. Cheers
It would seem that pouring babbitt would be just the sot. But Keith has a different take on it each time. Thanks for the video
I have seen this many times before Keith. It was much appreciated, but new content would be good.
Looking good!
Hi, Great video. Have you ever tried using the yellow Time Saver for lapping in the bearings?
Thanks Keith
love your videos
That's funny. I was sittin here thinking that he should put the damming on the inside face and squish it in with clamps.... lol
looking good
Seems like only two of the spacers need to have the step. The other two could be flat rings. Two points make a line.
Each episode gets more exciting. Can't wait to see that monster whirl.
Dunno if I missed it, why no sooting the shafts?
Good morning
Like other subscribers have said "You make it look easy". I noticed one thing different from other pours. The mandrel bearing surfaces were not coated in soot and it didn't seem to effect the removal of the mandrel form the pour. My question is how do you know when to coat and when not to?

The file that you used has the same pattern on it as the body files that are used to smooth lead in body work.
I have a 1969 Well Index 845 and just upgrade my old glass scale DRO PROS to the same unit you installed on yours.
Keith, you normally blacken the shafts to prevent Babbitt from sticking.
Was there a reason you didn’t do it this time?
Good morning Keith1 Great progress! Have a great week!
Nice.
Babbitt pours with Keith are my kind of ASMR.

I was wondering how the mandrill would be centered in the frame, now I know.
As always I enjoy your videos. I am curious , usually you carbon up the shafts when you pour babbitt , but you didn't this time. ?
Happy Monday Keith! 😊

was it something about the mandrel surface that made it so that you didn't have to soot them up?
Why did you not suet up the shafts before the pour? just wondering.
cool
Removing excess Babbit - would it be possible to trim the excess off with a wood chisel?
Nice work! How did you determine the diameter of the shelf on the damming rings?
why not put the mold-pac on both surfaces, before clamping?
how much oil clearance do you need for a babbit bearing?
Let's get at it!
Do you check straightness of the mandrel before pouring? While I own a vehicle with poured bearings (an old Ford) I'm a modern engine guy so I always assumed things like this got line honed after pouring.
Unfortunately one of the bearing caps is missing a mounting lug. Wonder if that's an issue you need to address?
Maybe (at 23 mins) pour in the centre, nor at one end? Regardless, an interesting video and outcome. Thanks.
threads on the ends and the middle, BIG nuts on the ends and the middle to tighten the flanges on the cast iron, possibly?
quick question... if the babbitt bearing is a little bit tight... can you just put some lapping compound in there and work it for a minute or is scraping a better option? will lapping compound embed into the babbitt?
I'm sure regular lapping compound will embed into the babbitt, according to some people diamond based lapping compound can embed into cast iron too.
@@ruben_balea OH. good to know!
Looks like one of the bearing caps has a piece broken off. Is Keith going to repair that before pouring the Babbitt in it?
Why didn't you soot up the shaft?
I did not see you soot the shafting to keep the babbitt from sticking to the shaft
Any reason you didn't 'smoke' the shaft ?
That’s a vixen file, they are hard to find and I use mind in aviation sheet metal work.
So are the Donner and Blitzens!

Sometimes also called a Dreadnought file

I thought the same thing, we have watched so many of his videos we expected this step
When you say 250°, would I be right in thinking they're using the Fahrenheit system, or are you using centigrade?
Yes, he uses Fahrenheit like 99% Americans. In slang language are called "degrees Frankenstein" 😅

just a quick question why are there sparks at the start of some cuts? please
it's where the cutting tool is hitting the hardened steel from the cutting process
@johnmolnar2957 thanks 👍
Question; you didn’t smoke these barbets any reason???
I wonder whether filling the keyway with damming material would have been a way to use the actual shafts for the babbit pours.
I was thinking that filling the excess keyway with brass braze would do it.
Since he had the shaft in a lathe anyway l'm curious as to why he didn't just weld up the overlength part of the keyways.
He went over all of that in the last video. Gk watch it
I would be concerned about trash getting into the bearing surface and causing damage if he leaves the keyway open.
I agree with brazing that in solid and machining it to size.
why are you using oil and not food grade grease? won't that need to be cleaned off 110% before using the mill ?? I assume it will be used once in a while ?
I guess he's using "way oil" or hydraulic oil and those aren't toxic.
It will all wash off when it's used as an anchor for the Tally Ho Ho Ho!
@@ruben_balea no but they taste like crap 😂
👍
No carbon smoke on the mandrel this time? Any reason other than it smokes up the workshop. The earrings look good, nice work.
How do you make sure babbit bearings are holding shaft square to a big wheel? This is something about scraping that was always confusing for me ,how do you keep things parallel and square.
It’s not a super precise thing with this type of equipment
It really does not matter that much as long it is close to being square, this is hardly a precision machine.
👍👍👍👍
Because you didn't use the original shafts with the gear install, how do you know if you have proper tooth engagement?
General area is good enough.
The tolerance on this stuff is huge.
He already turned the shafts and had the diameter. The Mandel shafts have the same diameter.
@@hobbiesrus That doesn't answer his question at all.... He is asking How Keith knows if the gear will mesh correctly with the internal ring gear (not too far down not too far up), just having used a shaft and rings which are centering the bearings in the middle of the casting.

Did you forget to smoke the shaft?
"Oversize for shrinkage"? When the babbit shrinks when it cools and the mandrel expands when it's hot the finished bearing will be pretty sloppy won't it?
Good question. Hopefully the combination of heating, cooling and shrinkage will result in the perfect amount of clearance.
I'm wondering if you watched the video to the very end where he installed the shafts ... which it turns out was a bit too snug.
Everything this guy dose is "pretty sloppy"!
