[@2xKTfc]

What's up with this customer pulling a machine off the job before the part fully grenades itself? Next thing you know they're going to put GREASE in their machines 😄

[@25centsapop]

I wouldn't have believed it unless I seent it

[@ethanandres5838]

As a younger person going into a larger field of work similar to this I find these videos to teach me and entertain me, I don’t walk away from your videos thinking I wasted my time on that. I appreciate you for sharing your knowledge to us, Thank you!

[@woodartist2021]

Wow! This is an excellent tutorial on lineboring, building out with weld material, and all the rationale for why you did it the way you did. And did it properly without taking shortcuts that would have failed, likely within a few months! I love it when things are done correctly, and not just “good-n-nuff” for now! Thank you for the painstaking effort you went thru to film all this. Thanks for sharing your machinist and welding skills with us also! As an aspiring welder, who plans a side hustle when I retire, your videos sure are a great reference for me. Thank you Greg!

[@mitchweber7868]

You're talking about the guy that said well you can just weld that by hand. When i first daw the channel about a year ago i was blown away. I can't believe this is a real thing i would have figured some company just makes an oversized bushing, you machine it the hole, pop it in and thats that. Idk ehy but the fact that this machine slso welds to me is just crazy lol 🤣 thats awesome 😎

[@Joe___R]

Stanley tape measures are the best, but you should still always check the scale against a standard to guarantee you don't have an odd bad one. I have only seen one Stanley that was off, but I have seen a lot of the cheap brands be off over the years. At the factory I worked at, we would have to get our tape measures certified to ensure everything was made to the same measurements. The cheap tapes they would buy at least 1 out of every 20 would have to be thrown out. China doesn't care if the measuring tools they make are accurate.

[@ssmith6019]

Love watching all your videos thanks for taking the time to make them.

[@paulcowler4136]

The thought and attention to detail second to none. The line boring equipment is a marvellous bit of kit in the shop or out in the field. As my Dad used to say if the tool is available use it. Great video as always. Paul Uk

[@timtrax918artisan8]

Math class is very important kids, pay attention

[@AceOneOne]

the elusive grease worm is a rare sighting among wild machinery

[@tdotw77]

Good thing it didn't bite him when trying to remove it!

[@MrRebar15]

*On Fire Welding* Bravo well done as always, doesn't take too many picks from that bucket to fill up that dump truck. Thank-you sir for taking the time to bring us along. GOD Bless.

[@McNeillWelding]

Wow that was a lot of work. Can’t believe anyone would say anything bad about your work. Look at his shop truck tools or any repair video people. Top of the line everything. Thanks for sharing.

[@Booker58]

I would really love to be able to do that type of work..... You are a true tradesman.. I like watching all your video's..

[@iainkinsella4708]

Thanks for explaining centering, always curious how you do that with whacked out surfaces.

[@raimundooliveira9953]

✌️✌️

[@jakedoom8807]

just eyeball it with a tape measure for a rough cut... or you could cheat it into a roughing location by maching some sloppy sleeves out of recycled PLA casting, if you dont want to build up 4 layers of weld.

[@ggcutter4098]

i use wd 40 in the field for pressing them in , dry ice in pellet form in the shop if you can get it add acetone to the dry ice , nice work as always

[@snaplash]

Or, a good soak in liquid nitrogen would let you push the bearing in by hand in a couple seconds, but that could take longer than pressing it in if LN2 isn't readily available in your area.

[@waynebinks1091]

I know nothing about machining but I appreciate how you can make a silk purse out of a sows ear! End product is beautiful.

[@sjohnson1776]

Impressive as always. Thanks for bringing us along and detailed explanations. Much appreciated.

[@Prander5x5]

Good stuff as always! Thanks for the video and the work it takes. Always appreciated.

[@kwaaaa]

As somebody far from this industry/field, how does one learn all of this? It's very intriguing how people like you and CEE are just crazy knowledgeable with seemingly every odd scenario that needs repairs/rebuild.

[@OFW]

We are good at improvising. We think in a different way than most people. All my knowledge is self taught. Learning from every job I do.

[@kwaaaa]

@@OFW Really impressive! Respect for people who can figure stuff on the fly and anything thrown at them.

[@paulhammond7489]

Nice to see that automated facing tool, it's a nice piece of kit, and one I have not seen before. This without doubt is the best line-boring video I have seen. Keep up the great work and content...

[@TacticalMainframe]

That looks fantastic. Amazing refinish

[@manbearpig2164]

That bore welder is cool, you got some skills dude

[@stevewesley8187]

Bad case of grease worms and lots of use ...........

[@ragnarironspear1791]

Really interesting work very much Luke Cutting Edge Engineering in Australia 👏🏻👏🏻👏🏻👏🏻👏🏻

[@jspice-kl2wc]

You do amazing work, thank you.

[@sidschwan8031]

Hey sir at first I was kind of skeptical but noticing how you did all the work turned out very nice congrats

[@terrminatoragain461]

Excellent video and great job again !

[@christopheranton3759]

Amazing craftmanship. Nice work!

[@brandygray5894]

A true craftsman, it was a pleasure to watch!!!

[@frfrpr]

Geez, this guy is definitely at the top of the pay grade. Pretty nice video and editing too.

[@rudyrivera7426]

Great work! As always! Thanks for sharing! 👌👍

[@auntpatty]

I really enjoy your videos. Particularly all the details like the dial indicator and how you find center. The more detail the better.

[@1leggeddog]

This is so awesome to watch. Perfect with my Sunday morning coffee

[@glennhotchkiss7900]

Outstanding! This is why I watch your videos. You spend the time showing how to do setup. Nice work centering the bar!

[@johnfry9010]

WOW , that was an amazing amount of work , nicely done !

[@Dibulok]

Man you are a hard worker. Thanks for another great video. Cheers from Sweden 🇸🇪

[@mackellyman5642]

Nice touch showing that magnificent machine in action; gotta love CAT...

[@DXT61]

I'm fixing to run down to Harbor Freight and get me one of these here line borers. 😀 Adding that shoulder makes it better than factory.

[@25centsapop]

It's practically like free class and lessons on line boring I can't tell you how much that gets me going haha as a heavy equipment field tech that's a closeted machinist I dig this

[@ToFinka96]

Great videos! As a engineer I watch these before I go sleep :) Love it!

[@queridabelemacai3974]

... Perfect work. Congratulations!!!

[@omarandpedro]

stand back and admire your work. what a great repair

[@DaleDirt]

Great content and quality , I learned alot . Thank you

[@troubleis5271]

another great tutorial from OFW - loved the close up shots

[@lancehenthorn17]

Nice work. Well past my skill level! Really enjoy watching your videos.

[@MLDIYSH]

Absolutely love this video. You are a one stop shop. Bravo

[@trevorwhalley7466]

Sir.To watch you at work is interesting, educational and rewarding, your knowledge and the machines/tools you have and know how to use and explain is incredible, whatever you earn, worth every cent .

[@kerrygleeson4409]

Quality all the way fantastic job as always 🦘

Trabalho perfeito como sempre amigo!!! Boa sorte sempre!!!

[@ExSheriffFattyBoySkinnyArms]

This work is so fascinating!

[@garthadams9765]

Onfire welding to the rescue, when you need welding and repairs done who you gona call. A job well done sir

[@johncamp7679]

I’m always amazed by the tools that were invented to fix things. Who knew this existed? I’ve never seen this type of repair job, but I knew right away you weren’t just going to cut it out. I knew there were a lot of problems with that, aligning, material loss.. I just didn’t know how you were going to do it.

[@zoltannagy1813]

A big job and well done. Now I know how you face the ends seeing the facing tool for the first time.

[@murrayblack4371]

Job well done. It is eye opening to see all the steps needed to do a proper job.

[@garyrhodes7089]

nice work i hope your customer appreciates the time it takes to achieve this level of precision

[@marcluiten]

always informative and interesting. keep up the good work

[@APNFORD]

Great timing, i was searching for something to watch! Love the videos!!!

[@mackellyman5642]

Oh, by all means, please don't get any on ya...

[@howder1951]

Nice work, I love the transition from junk to like new. Nice bushings, I don't think I ever came across that dimpled design before. It sure looks like it will keep a huge grease reserve compared to smooth surface. enjoyed, cheers!

[@gordonagent7037]

Fantastic job and might I say, a big shout out to all the comments makers as your comments are so helpful and help the project safety out alot

[@jerryglenn7323]

You are top notch business!

[@haxguy0]

Amazing stuff! Looking forward to more content from you

[@C-Culper4874]

Dry ice is your friend. I replace walking beem centers on a dump truck this past week. When they quit squealing like baby pigs they are ready. Lol

[@masseymm]

best explanation yet on any line boring video I've watched and for some reason I've watched many

[@ghilreese3413]

Nice Job. Thanks for the videos.

[@mickbaker2483]

Hi it alway's fascinating to watch the thing's you do on all of these machines many many year's ago I worked in a plant workshop's and all we had was gas bottles and a very big 28pound Hammer to put these bushing in with, but I watch the thing's you do and you make it look much easier than the thing we used to do hear we have even welded machines up knee deep in mud in the middle of winter just to get them back to the workshop's but I wouldn't change a thing, it great to see your work ethics and how dedicated you are to your work and customers thank you for another informative and interesting great video.

[@OldGuyAdventure]

That is one beautiful job with a bore welder; well done. I always love the know-it-alls. I have only welded on farm equipment and some as a maintenance tech for an extrusion company. But there are days I wish I would have taken up a trade and welded.

[@frankroden8233]

Great Job ...It's alot of work ..but the end result was spot on !!!!

[@carloskawasaki656]

Thank you for sharing, another great project, i learn a lot 👍👍👍👍

[@Ian-iu2tl]

I used to do this years ago. We used a tiger torch to heat the bore and chilled the bushing with liquid nitrogen. The bushings just dropped in like nothing. Sometimes we used a horizontal mill...made things a lot easier for that chamfer by using a boring head. We also used a micrometer feed for the cutting tool that could index the cutter to depth at .0005" increments for very accurate cuts. For measuring the bore with the line bore bar still inside the bore, we used an attachment for a bore guage that spanned the bar...very accurate as sometimes the math on a cut would be good but the cut could go wonky after the bore has been cut...oops!!! Kinda' like a rocket launch...fingers crossed without the micrometer adjustable tool bit holder.

[@theessexhunter1305]

Very very neat, not easy by a country mile. top job

[@Okie-Tom]

It’s simple! Quality tools, knowledge how to use them, quest to do quality work. Equals very good results. I enjoy these videos very much.

[@sccolbert]

That's one helluva repair!

[@Joel-st5uw]

Wow, that thing was well and truly rogered. Thanks for pointing out the challenges along the way, like how the second face was deceivingly low. Just goes to show how these jobs take a LOT more effort than they appear at face value (pardon the pun). Great stuff, I like these long, deep dive repairs!

[@user-vy8lp1zv8z]

That is cool and crazy, crazy hours of work.😮..

[@horstszibulski19]

Thanks a lot for the in-depth explanations... 👍 Seems that it takes nearly a week to get such a job done, wow! 👍👍👍

[@darrinstone49]

Wow you definitely burn through alot of wire! I'm impressed! Amazing high-end machines!,

[@okanagansawmill]

Very nice work!

[@victorjeffers1993]

That was a extensive job several hours but as always job well done in the end ! And as always very professional ! Thanks for explaining how you get center when line boring worn holes ! I also liked the inserts you put in for the bushing to butt up against to keep them from sliding towards center ! I can tell you take pride in your craftsmanship ! 👍👍

[@hawk7947]

Several hours? Dude try probably 20+ hours for this. I don't even want to know what he charges for this. Cat charged me 3k to line bore a new attachment hole on a quick disconnect that was brand new on a small e85 bobcat lol

[@steveanderson4768]

Absolutely awesome video. I like how you explained how the facing tool works. Very simple design very simple operation and how do you measure everything that really is quite simple truly is an absolutely dead precise when you measured it all and you were .0005 off that’s not too shabby and with a .006 crush you’re good.

[@conradward2945]

Crackin video! Great explainations

[@jamescheever7982]

Great work !!

[@xjinit]

Love the videos! I do find it hard to believe it would be more work to replace that piece all together.

[@jackdawg4579]

nicely done. Must be a real exercise in patience all that bore welding!

[@GriffithsFfestiniog]

Excellent job always a pleasure to watch a skilled and knowledgeable professional at work, very interesting video just the right amount of detail. Thank you

[@ypaulbrown]

beautiful work Greg.....Bravo.....Paulie down in Florida

[@todddooley793]

Nice job! Man i wish i got into this type of work

[@segomatu7063]

Tes vidéos sont toujours intéressantes et captivantes mon ami ! Good job !

[@albanliege4989]

very good and very nice work !!!!

[@user-David35]

looking forward to your video. Thank you.

[@about2mount]

I spent over fifteen years making Bushing and bearings for Cat among others. I done all these on Programmable Mazak Lathe Machines and Horizontal Milling Machines to drill and tap the grease inserts. Many may not know it but they all require Bronze Inserts with oil galleys cut into them which are the Bearings for those massive Bushings.

[@scotthultin7769]

1.2K+ 👍's up on fire welding thank you for sharing 😎

[@garyyorke1080]

Well young man that was a very interesting watch great information on actually how you do the line bore welding and how you measure it all out. Also as you say 48 minutes in 15 seconds . That makes that a long job .. not a 5 minute as it seems on video . Many thanks

[@gabekamphuis]

respect ! for this job ....

[@jacquesvanniekerk2896]

I grind a grease 1/2 inch groove from the grease hole to the outside and inside . If the bush drifts, your bush does not cut off the grease supply.

[@MyLilMule]

That facing head is pretty cool. For that outside chamfer, maybe a large button insert would be useful and give that piece a radius instead of a flat chamfer.

[@OO-xc7zg]

Well done! 👍👍

[@randycordes464]

Thank you for your video there great

[@DPW55]

Very interesting,well explained in detail,
