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 😄
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 😎
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!
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!
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.
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.
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.
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.
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.
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
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.
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 .
*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.
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
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...
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.
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
That's a big job! It looks like 40-50 hr job! The facing tool is very cool to make it advance along the radius all by itself. CEE doesn't have that! 😉😉😉
CEE does infact have a facing head for their line boring machine but it's too big to fit properly in the original bearing mounts. That's a reason of why Curtis made new mounts a while ago, I think we will see it in the future.
Very impressed, I agree with bore welding, Welding by hand is just NO, not even attempt it. I've been welding for 44 years Paid for it for 39 years. Not only keeping it consistent, I'd like to see someone do it by hand too. Love your line boring tooling, looks like might have cost a few bucks. I have an idea for you chamfer but find it difficult to explain with keyboard. I would make 1 tool holder adapter and feed a 45° carbide straight in slowly, but because how slow it needs to be fed it might not save time (20 mins). Those little imperfections will be totally fine. I didn't realize how many hours were involved. It came out real nice, Well done.
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.
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!
If you can outfeed your facing tool to the same feed rate as the thru travel feed rate, think you could get a 45 chamfer like a Wohlhaupter auto facing head. May have to snug the bar collet and facing head gib to reduce chatter. Climax might have other suggestions. Nice video OFW!
Hi, Had a think about your question on how to create a even chamfer. The problem is to much tool face which causes chatter. I think you need to make a holder set at the angle you need to drill a piece of bar round or square with a hole down the centre the tool shank size. Mill a flat on the tool shank and then on the holder drill and tap a series of holes. Use machine set screws to keep the tool in the right orientation and you can advance the tool out on the angle so you take a cut back off advance the tool and go back in that way it will be small steps just like on the lathe feeding in by hand. Regards Tried you email address but the US side is rejecting it so sent it here.
HE Operator and mechanic - retired. Did bits of everything in repair. No "machining" though. But I was with ya all the way. All of these great replies shows there are a lot of us more interested in metal works than movies. Thanks so much Greg ! Carry on 👍
man, what is your background because you really know your stuff. It always comes out good. Like i have done a little schooling in GD&T and understand everything you are discussing, but this does look intimidating with no practical experience.
I am planning to do a video on my background and how I got started. But basically I worked at several welding shops and a couple machine shops all while doing side jobs at home. But everything i know about line boring is all self taught.
@@OFW that gives me some confidence. Been around shops most of my life and will be doing an apprenticeship for a boiler maker company. So gonna get that good good welding experience in for the next few years. I'll def keep a look out for your video
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.
That is, no doubt, one of the best, most informative line boring instructional videos I’ve ever watched! It would be interesting to know how much equipment that your videos have sold for Climax.
I was training in 1973 to do line boring on cat equipment all the tools were hand made love your system but the welder blows my mind way cool.the guys that say hand weld always passes the machine part off to someone else.your chamfer can you get it in the facing attachment start out and face in.
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.
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
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.

Bad case of grease worms and lots of use ...........
Hey sir at first I was kind of skeptical but noticing how you did all the work turned out very nice congrats
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.
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.
@@OFW Really impressive! Respect for people who can figure stuff on the fly and anything thrown at them.
Дуже захоплююче та повчальне відео👍
the elusive grease worm is a rare sighting among wild machinery
Good thing it didn't bite him when trying to remove it!
Love watching all your videos thanks for taking the time to make them.
Really interesting work very much Luke Cutting Edge Engineering in Australia 👏🏻👏🏻👏🏻👏🏻👏🏻
Thanks for explaining centering, always curious how you do that with whacked out surfaces.
✌️✌️
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.
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

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
That bore welder is cool, you got some skills dude
Geez, this guy is definitely at the top of the pay grade. Pretty nice video and editing too.
Nice touch showing that magnificent machine in action; gotta love CAT...

I know nothing about machining but I appreciate how you can make a silk purse out of a sows ear! End product is beautiful.
best explanation yet on any line boring video I've watched and for some reason I've watched many

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
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.
Outstanding! This is why I watch your videos. You spend the time showing how to do setup. Nice work centering the bar!
Impressive as always. Thanks for bringing us along and detailed explanations. Much appreciated.
stand back and admire your work. what a great repair
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
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.
Absolutely love this video. You are a one stop shop. Bravo
That is cool and crazy, crazy hours of work.😮..
Nice job! Man i wish i got into this type of work
Quality all the way fantastic job as always 🦘
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.
A big job and well done. Now I know how you face the ends seeing the facing tool for the first time.
That's a big job! It looks like 40-50 hr job! The facing tool is very cool to make it advance along the radius all by itself. CEE doesn't have that! 😉😉😉
50 hours exactly!
CEE does infact have a facing head for their line boring machine but it's too big to fit properly in the original bearing mounts. That's a reason of why Curtis made new mounts a while ago, I think we will see it in the future.
@@viktorsmekaniska2733yep, he does I have seen him use it at least once. It looks like a Hoffman head.

I really enjoy your videos. Particularly all the details like the dial indicator and how you find center. The more detail the better.
You accomplish more in the first thirty minutes of your day than most today's guys can accomplish in eight hours.
