Remote grease zerks are fantastic for things you can't access due to location or safety shielding. Had steel plates with zerks and grease tubing going like spaghetti to all the bearings on equipment at a gold mine I used to work at. Kept things running in a terrible environment. Might be worth mentioning to your customer even if you're done with this job, just so you don't get this headache back in your shop. Keep up your awesome work, and thanks for sharing your craft and expertise!
HI KEITH JUST POPPED IN TO WISH YOU A HAPPY NEW YEAR TO YOU AND YOUR FAMILY. AND I LOVE THAT YOU ALWAYS STAND UP FOR THE CONSTITUTIONAL FEDRAL REPUBLIC. AND WHAT IT STANDS FOR . PEACE BROTHER.
"sometimes u need a small puller", can't wait to see your big puller, Brill keep em coming, superb, ur a dying breed these skills are dying out, did the basics years ago but now desk bound to a PC.
glad you playlisted this one keith, i watched it for the Nth time a couple of weeks ago and it's easier to just hit "go". your philosophy on workmanship is evident in this series, and i wish more people would catch on. another suggestion? the wright stick trilogy!
I've built guards, and one important factor is, to make it possible to grease hidden areas. One way it to add extension tubes to zerks, secured from vibration, etc. There can be holes in the guards, so a grease gun can access them, or make access doors, which must be secured by bolts or screws, requiring a tool to open. As far as I know, thumbscrews, other tool-less access is a safety violation. Making it less of a hassle to do routine maintenance is important, when installing guards.
"'We got a little noise coming from this thing.'(shows slop) You think?" Hilarious. It is a good thing no is here today to listen to me laughing in my office. Another great video. Thanks.
....my saws making noise..haha....."don't you shut that saw down...!, we gotta get this job done".....the "Blue Collar Struggle"..... thank god for the machinist.....its all just one big well-oiled machine... thanks for another great video
Well Keith I did have a good laugh thanks. So far there isn't anything you cant handle but to tell you the truth your going to impress the hell out of me if you can pull this one off. Cant wait to see this 10 part series. LOL !!
hello Keith love the work you do, these are the skills that engineering needs to pass on to the next generation of apprentices, i think the uk is finally waking up to the fact that there are only so many service industry/desk based jobs. i did my 5 years got my qualifications worked hard did the work to the best of my abilities and so far have been out of work for about a month in 32 years. ps add a grease gun and a pot of grease to the job! many thanks magnahelic
I went to the local mill creating finish boards ant their saws were mounted with the pistons and rods from old diesel engines. The piston was mounted to the wall frames and the rod ends to the shaft. Worked great and looked safe
I happen to have a German saw from the 60's and it has lines running from the greasing points to an external grease nipple array, it also has a greasing schedule engraved on an aluminum plate and a grease gun mounted right under. A worthwhile mod on the saw you're repairing, that should help with maintenance.
My brother inlaw had a big clamshell puller like the one you show here, he didn't know what it was for but I shit you not he was using it to cut down small trees LOL needless to say I am the new owner. Great video
Every once in awhile at Northstar propellers, we had to go down to the Union Tribune in San Diego to use cooper heat, to swell the bearings and slide the paper rolls within the bearing mounts to give new edges to the paper to ride on, so it wouldn't tend to rip or tear. Paper is surprisingly abrasive, by itself given some time! ;{)---
"Small Puller", yes, you're a funny guy!! I've always liked those Dodge T-locks, great part for the price I was Maint guy at a couple wood outfits, they didn't like to shut down for any amount of time to fix stuff that "Wasn't Broken" Ear plugs all the time, you couldn't hear the bangin and whining of bearings. Here in Sacramento, there was a saw shop that made any kinda blades, chop-saw up to 60", carbide brazed teeth, 2-5/8" bands also brazed carbide teeth, as long as 40 feet for logs...
We work on that kind of machinery wear all the time. For us it's bronze bushings worn thru, or roller bearings froze and the shaft is turning on what used to be the bearing fit. More time passes. At last, the machine function has been so degraded that they just have to take it out of service. We get shafts worn a third of the way thru. We do a condition found on the hardware and decide what and how to rebuild it. Lots of work, but when done the machine is good for more decades of service. This is one part of the machining industry that just keeps going.
Great video, I love jobs like this. Restoring old equipment makes by business partner hate me, all he wants to do is get the piece work. I love the craft! Keep up the good work!
At the local scrap iron there was a loud screech comming from the stick pin on the excavator with the electro magnet. I pointed it out to the owner and he stated "The greese guns just walk away from here..." As my dad taught me check the grease and oil the fuel will take care of its-self. Looking forward to your next installment.
Your guesses on all the reasons are correct! It is a better choice more so to comply with the environment. You could use the shaft to dam the Babbitt material in place and then just scrape for the finale fit. ;{)---
Was my first impression too. But thinking about it.....there is a lot of hidden work in there. If he had the whole machine, motor, frame etc. in the shop it would be a tad bit easier. But still....there is some RD work involved. It takes a surprizing amount of time to figure the right hole patterns and sizes, work around some casting specific details with your fabrication. And in the end you would still have to chuck up the new assembly, bore it, babbit it and bore/scrape it again.
Would it have been an alternative to bore out the large bracket, press in bronze bushings, and have a new shaft ride on those? Another fascinating video! Thanks for going to the trouble of sharing it all.
@FRUNTCASTER They both would have the advanage for a longer life in certain applications, like you would want a ball bearing in a rock crusher knuckel and you wouldn't want a babbitt bearing in your high speed pea grinder! Yes, Babbitt is a bearing, all other materials like bronze, nylon etc. would be called a bushing.
Holly cow Keith ya got yourself a good one this time. I guess at least a four part series. If you can fix that mess you might think about a job in Vegas I here magicians make big coin out there. Can't wait to see how you tackle this job. Catch ya latter.
Note to those who change their own oil (on their ford van): don't forget about the zerk fittings. Lets just say ball joints and tie rod ends need grease.
machine maintenace in the machine shop I work at is done when the won't run anymore. Our managements philosophy, "Lets get through the next job then we can do maintenance".
When people put the machine back together, they should think, and make a simple way to run an external grease line to the bearing for easy access without having to remove a guard or shut down the saw, or any equipment at that. From experience, it makes life a whole lot easier. I would rather spend the extra hour doing that, rather than rebuilding it every other week. from experience I know that it works, because I have done it. but make sure to check over the machine regularly to prevent damage. tons of vibration there, the person running the saw is lucky it didnt shake the blade apart
Whats that noise at 3.08? ;-) Great video's. I am not a machinist, but I love seeing how stuff works, and how it can be mended. I myself get great satisfaction from repair and renovation, buying new is kind of wasteful. You look like you care about the job first, your personal pride in your work is very refreshing.
Good god, that looks like some of the guns people bring me to work on. I had a revolver that had 4 bullets piled into the barrel, #5 locked up the cylinder in the forcing cone and #6 was unfired.
I think that was a piece of alum flashing catching on rag or pressure popping, when I was moving around during the roll over, It is in a few other spots in the video. I use it in the K&T for splashing detainment. One possibility anyhow! ;{)-----
I had been buying my Babbitt from MC Master Carr, but they have raised the price too much! I'll need to research myself when the time comes for needing more. ;{)---
Hmm after thinking this over, i conclude that with babbits poured in place, i dont need to line bore either the jaw or the frame of my crusher... just need to build my shop press first, to press the shaft out of the jaw after pouring, then sandpaper it with a sandpaper on a stick. I made one in the angle grinder, a 3/4"pipe with an M14 nut welded to it, to ream bushings after they shrink from welding them into place. Its pretty vicious at 6500rpm though...
It must be said that while neglect is what we repairer's and fabricators make a living from it is also one of my absolute pet peeves! Sometimes stuff breaks of fails due to poor design or quality materials and or workmanship but bearings failing like there here is just plain piss poor maintenance, regular inspection and greasing would likely have prevented such an extensive repair. Still when people just don't maintain their machinery it means we can live :)
I have a lathe that apparently got a piece of steel caught in the wiper and scratched the ways. Any suggestions on how to get the scratches out? I thought about lapping it. I'm going to order new wipers but I'm still stuck with some scratches. Any suggestions?
I love how much you enjoyed making this video even though it was the job from Hell, I bet you got paid to do your magic. Classic video I just had to re-watch, and it turns out that it was the 1st video if yours I watched that got me to subscribe to the channel! Thanks for making these shows...Aloha, Chuckie
RG7 is good for medium pressures and I can't find any RG 12 info but RG10 is shock resistant and heavy loads, I haven't worked with any rock crushing equipment in 20 years now but never seen anything used except Babbitt for bearings and would be hesitant to think anything would perform any better. ;{)---
I have worked in the corrugated paper industry for 15+ years, and I have seen solid 5" steel shafts wear in half and fall out of machines, I ask my self how can they let it get that bad? what does a tube of grease cost? one of the best ones I heard from a operator was " It was working fine untill all those springs came out of that roll." ( Metal shaving from a previous repair ) It was amazing how neglected some of the machines were.
Keith, how often do you do shop maintenance/ cleanup. From the looks of things you keep a very tidy shop. Makes me grind my teeth to see a shop that looks like a tornado hit it. Great vids and keep them coming :D
On a job like this do you quote a firm price, or do you have a clause for unforeseen eventualities? Just curious because some jobs look to be straight forward and others look like nightmares. lol
G'day Keith first I love your DVD's it's great to see a pro such as yourself at work, which I suppose is rapidly becoming like most trades Automated. In regards to those bearings it's annoying to see that kind of damage due to neglect, in the case of the bearings themselves is that what they call "white metal" like they used on old steam locks? Thanks again and look forward to the next instalment, regards John Kinnane Tasmania Australia
John Kinnane We call it Babbitt, "White Metal" over here is like low quality die castings poring metal none weldable and not a bearing metal either. ;{)-----
I'm in Europe, i cant find RG10 here but perhaps its the same as RG12.. What exactly makes Babbitt the bearing of choice here ? particle embedding capability, dry running characteristics ??? And do you allways need to actually pour a Babbitt in place ? Pouring it in place would probably mean i have to line bore the entire frame, which adds cost. Especially due to the weight of the frame..
I have worked for plenty of places like that. The workers are mutants and would not know what to do with a zerk if they saw one. Reminds me of the lady who ran over 'something' with her minivan. It made some noise, but she kept on going until for some reason it would go no more-she ran over a box spring mattress on the highway and it got wound up on her driveline.. search google images for drove over box spring mattress and look at the first item
Keith, will poured bearings outlast sealed or greaseable ball bearings, assuming both receive a regular greasing? Also, is it correct to call Babbitt a bearing or is it a bushing? Love your channel!!
Keith, what wall thickness do you recommend for a Babbitt ? thin means more risk in case of a misaligned pour, but thick means use of more of that expensive stuff... :) I checked prices for RG7 bronze and its over 18 euro per kg here, its a bit of a waste to lathe most of that to chips... With Babbitt i could use just what i need, and re-use if i screw up... Then i must find an adress for Babbitt here in Holland :)
I've seen you doing it in another video, but where do you buy the Babbitt material ? do you buy Babbitt melting pallets, or tin, lead and copper and melt them in the correct ratio ? I have tried Google on this, but no luck. Babbitt seems to be quite old school... But i rather spend my evening labour hours (on old school Babbits) than my money (on roller bearings) ;)
Out of sight out of mind for the zerk fittings. I'm surprised you didn't find a lot of new grease from attempts to "fix" the noise. Hour meters are cheap and easy to install, go a long way for maintain.
Some of this stuff that's been 'Boxed' is a good application for a few hoses and remote greasing? I agree that 'lack of maintenance' should be painful in some way.....
It really depends on the work load, I always clean the machine before starting to use it, like washing the car before taken a trip. It gets to the point I can't stands it no more, then I just take up the mats and put away everything and regroup. We all have are limits, sometimes they are put on hold to Getter Done. ;{)-----
@magnahelic1 Your spot on, we appear to be a nation of shopkeepers, insurance and bankers. Engineering company I work for had 8500 employees 15 years ago we are now down to 2000.
I'm collecting materials for a rock crusher i'm going to build. Heavy walled C and H beams for the crusher jaws and sides, old train wheels as flywheels and the train axle shaft as eccentric shaft. What exactly is the difference between Babbitt and RG7 or RG12 bearing bronze ? What modern equivalent bearing material would compare to Babbitt ? Thanks in advance :-)
Thanks, so my initial guess of 10mm (3/8") for my 5" shaft would be a minimum.. And about sanding to size, right after typing it i already thought that sandpaper and babbitt would go well together because babbitt is designed to embed foreign particles to keep them away from the bearing surface... Anyways i'll figure out another way to ream them to size :) Thanks !
I'm a complete novice... a woodworker ... but I came across your offerings and really appreciate your work ...
Remote grease zerks are fantastic for things you can't access due to location or safety shielding. Had steel plates with zerks and grease tubing going like spaghetti to all the bearings on equipment at a gold mine I used to work at. Kept things running in a terrible environment.

did u fart at 3:07 ? lol
sounded like it...lol
i think you have a sick duck in the shop
Did he fart again at 11:18 ? :D
I love how you scold the maintenance guys nicely. Cut a cord of wood is good advice.
mmm this guy is not only a good engineer... but makes it interesting... I would think he takes great satisfaction repairing things....
Hi Keith, third time I watch this series, love it, nice job, a good old handmade thumb up, Getter done
This is a revisit for me on this video and it still blows me away to see the shape of that setup and knowing it was for a wood saw. Scary sh&t!
"'We got a little noise coming from this thing.'(shows slop) You think?" Hilarious. It is a good thing no is here today to listen to me laughing in my office. Another great video. Thanks.

I love to see you fixing crappy stuff like this. I'm learning so much by watching you do your thing! :-)
Some of us woodworkers are just now learning about machinery. Be patient with us Keith!

Great vid as always, looks like a trip to Florida for Keith off this one.
Looking forward to this one :-) Sounds like fun...Especially your sarcasm :D
Your guesses on all the reasons are correct! It is a better choice more so to comply with the environment. You could use the shaft to dam the Babbitt material in place and then just scrape for the finale fit. ;{)---
No problem, I really enjoy watching your videos its better than most of the crap on tv
No problem Keith because the belt tension will keep the axle to one side LOL
Keith, I'm looking forward to seeing exactly how the heck you're gonna take care of this one!!

That reminds me of half the equipment on our farm. :)
As my old friend John used to say “Too much grease…….left in the can.”
6:30 "sometimes you need a small puller"
Sheesh! If that's a "Small" puller... what's the big one?
LOL
Gabriel Epelbaum had the same reaction :)

Good god, that looks like some of the guns people bring me to work on. I had a revolver that had 4 bullets piled into the barrel, #5 locked up the cylinder in the forcing cone and #6 was unfired.
"Sometimes you do need a small puller...." HAAAAAAA!
I think that was a piece of alum flashing catching on rag or pressure popping, when I was moving around during the roll over, It is in a few other spots in the video. I use it in the K&T for splashing detainment. One possibility anyhow!
;{)-----
Hey my saws makin some noise, my saw's makin noise... XD
priceless!
I had been buying my Babbitt from MC Master Carr, but they have raised the price too much! I'll need to research myself when the time comes for needing more. ;{)---

dude that puller looks like it would pull the propshaft out of a battleship
I'm Retired Now .... Things Like This Used Ta Keep Us Working ! So They not " Shop Smart "

Keith, how often do you do shop maintenance/ cleanup. From the looks of things you keep a very tidy shop. Makes me grind my teeth to see a shop that looks like a tornado hit it. Great vids and keep them coming :D
Try to keep grit away from Babbitt material it holds the grit within it self and uses it to sand or wear away on shaft. ;{)---
On a job like this do you quote a firm price, or do you have a clause for unforeseen eventualities? Just curious because some jobs look to be straight forward and others look like nightmares. lol
Most every project is time and material, I have some fixed rates and sometimes I just say not to exceed, this amount. ;{)------

+Keith Fenner Babbitt, its called in Sweden to. Invented in 1839 by Isaac Babbitt :) (Wikipedia)
I'm in Europe, i cant find RG10 here but perhaps its the same as RG12.. What exactly makes Babbitt the bearing of choice here ? particle embedding capability, dry running characteristics ??? And do you allways need to actually pour a Babbitt in place ? Pouring it in place would probably mean i have to line bore the entire frame, which adds cost. Especially due to the weight of the frame..
The US needs its good fix-it shows back. I remember watching Norm Abram.
Keith, Why is Babbitt used instead if converting it to a conventional ball bearing?
Bearing clearly undersized for its job what Hp was the drive?
I have worked for plenty of places like that. The workers are mutants and would not know what to do with a zerk if they saw one. Reminds me of the lady who ran over 'something' with her minivan. It made some noise, but she kept on going until for some reason it would go no more-she ran over a box spring mattress on the highway and it got wound up on her driveline..
search google images for drove over box spring mattress and look at the first item
Keith, will poured bearings outlast sealed or greaseable ball bearings, assuming both receive a regular greasing? Also, is it correct to call Babbitt a bearing or is it a bushing?
Love your channel!!
Keith, what wall thickness do you recommend for a Babbitt ? thin means more risk in case of a misaligned pour, but thick means use of more of that expensive stuff... :) I checked prices for RG7 bronze and its over 18 euro per kg here, its a bit of a waste to lathe most of that to chips... With Babbitt i could use just what i need, and re-use if i screw up...
Then i must find an adress for Babbitt here in Holland :)
Thanks for the laugh! ;{)---
Check Centaur Forge, They used to carry a variety of Babbit. I think Blacksmith Depot may also carry it.
That must have had serious vibration issues when running.
I've seen you doing it in another video, but where do you buy the Babbitt material ? do you buy Babbitt melting pallets, or tin, lead and copper and melt them in the correct ratio ? I have tried Google on this, but no luck. Babbitt seems to be quite old school... But i rather spend my evening labour hours (on old school Babbits) than my money (on roller bearings) ;)
Remote grease points are nice on heavy equipment to prevent that
Out of sight out of mind for the zerk fittings. I'm surprised you didn't find a lot of new grease from attempts to "fix" the noise. Hour meters are cheap and easy to install, go a long way for maintain.
Some of this stuff that's been 'Boxed' is a good application for a few hoses and remote greasing? I agree that 'lack of maintenance' should be painful in some way.....
What on earth were they using the saw on?
12 minutes in: tappity tap-tap-tap!
Replace sleeve "bearings" with SKF high speed rolller bearings - greased for life(10000 hrs) whole bridges has to be remahined anyway
that would be scary with a 36" saw blade with all that wear !!
It really depends on the work load, I always clean the machine before starting to use it, like washing the car before taken a trip. It gets to the point I can't stands it no more, then I just take up the mats and put away everything and regroup. We all have are limits, sometimes they are put on hold to Getter Done. ;{)-----
@magnahelic1 Your spot on, we appear to be a nation of shopkeepers, insurance and bankers. Engineering company I work for had 8500 employees 15 years ago we are now down to 2000.
I'm collecting materials for a rock crusher i'm going to build. Heavy walled C and H beams for the crusher jaws and sides, old train wheels as flywheels and the train axle shaft as eccentric shaft. What exactly is the difference between Babbitt and RG7 or RG12 bearing bronze ? What modern equivalent bearing material would compare to Babbitt ? Thanks in advance :-)
Guys who don't maintain their equipment keep machinists employed. They are a godsend when the bank account is running low.
What's that "noise" at 3min 7 sek?
im guessing they have had the belts over tight ,i have seen this before on a delt drive mower
Thank God for grease worms! Job security!!
I am amazed that it was only noise.Lou
@SJgunguy holy sh** you've got to be kidding me! That's close to being a Darwin award.
Thanks, so my initial guess of 10mm (3/8") for my 5" shaft would be a minimum..
And about sanding to size, right after typing it i already thought that sandpaper and babbitt would go well together because babbitt is designed to embed foreign particles to keep them away from the bearing surface... Anyways i'll figure out another way to ream them to size :) Thanks !
I would say a safe thickness would be 1/8 to 1/4 the shafts diameter up to 3" then leveling off to some extent. ;{)---
