Line boring CAT 637 hitch horizontal bores

I always look forward to your content , Curtis at CEI , Snowball and IC weld. thank you for sharing your work

My dad owned his shop 52 years. He was also a millwright. He was good at what he did the last 6 years he used to tell customers his prices were based on how many Fu**ks he would have to say to finish the job. And odd enough he picked up way more business because people got a kick out of it. Glad to see so many still doing a good hard days work. Unlike how some think 4 hours a day is just oh so much. lol

*On Fire Welding* Bravo well done, thank-you sir for taking the time to bring us along. GOD Bless.

even though i know Greg is a professional and experienced welder i still marvel every time with the precision at which he can hand weld with such consistency and accuracy. I still have so much to learn......thanks for taking us along again.

Thank you for sharing, always a pleasure watch your project, I learn a lot 👍👍👍👍

I love your work Greg, it's amazing to see how you bring such wear and tear back to as-new condition. Thank you from London UK.

The bore welder has to be your coolest tool in the shop. If not, show us what you think is the coolest. Love your content.

Sounds like you're feeling better. I'm glad to hear that.

always great to see my favorite channel...Greg and On Fire Welding....cheers from Florida, Paul

Speaking only for myself, I enjoy your boring videos.

What a great job! Thank you for sharing.

glad your sounding better

Thanks for your Videos! Learn something every time.

Keep em coming Greg my friend! Love your content.

Amazing as always. Your work is pure art my friend.

I always liked line boring videos, the centering set-ups are interesting.

Thanks for the welcome back, ❤ Check out that cool welding helmet with a skull 👍 . Just another awesome line bore job professionally done !!!!

Always a pleasure watching someone with skills. Cheers from the mountains of New Mexico.

You're the best, keep the content coming!

Always enjoy your videos. Seriously talented dude

I liked how you cleaned up the outer edge of that repair, and thought that it would have looked better on the single one if you did it there as well. Great repair though, soothing to watch!!

Wow. I'm always impressed with the result. What a great job. For the client asking to make those reparations for sure it must be more economical than buying a new hitch. Bravo.

always a good day when I see another line boring video uploaded :D

Well done!

Great video as always!!!

Great job Greg maybe one job we can see the new boring machine we got to see looks great😊

Really nice attention to doing good work.

I'm a lathe machinist from Italy🇮🇹 and Seco are probably the best insert!

I enjoy your content and wish there were more scenes from all of your work. Thank you.

Again I will say it. What a craftsman.

647 👍's up on fire welding thank you for sharing 🤗

Great video, thanks for sharing.

I brought my lunch today to enjoy while you work. Steak and shrimp!

Great stuff!

fantastic work.

Gregor wherefore art thou??? Hope you are well and the Easter Bunny left you plenty of chocolate!!!!!

Whaou 😮 turn welding is so cool Tank you to show us this professionnel work 🇫🇷🧑‍🏭

Nice Job!!!!!!

Great Job.

Alright! Been waiting ,Morning coffees on! Cheers!;-)!!

Best welder west of the Himalayas

Nice work

Outstanding. Line boring is interesting. Probably easy to get wrong though.

I loved the Earl Scheib advertisement “I paint any car 99.99😅

25 years of steady line boring and I don't miss it. Bars up to 16 ft. long. Double side bearings, single side bearings, Spider bearings, and spiders with brass bushings. I owned one of the early bore welders.

Good stuff

Yeah totally use your inch and a quarter bar with the setup cones for tacking on your big bearings using the reducing collets. much easier to dial in the bar and that way you don't wreck the big bar with the welds spatter when tacking on bearings

Very neat, not easy creating those flats without a trepanning (facing) head which would be a great tool if someone made it for that set up.

Thx man!!

You see the curve of the conduit has to match the the rotation on the bore welder. It also makes a difference If you're pulling off the top of the roll or off the bottom of the roll of wire. Like I said my wire feeders a little different and I pull off the bottom of it. So therefore I have to go to the right into the bore welder and have the bore welder rotate right. You don't want to unbend the Natural curve of the welding wire when ots inside the conduit If you can help it. What you can do is pull out about 10 ft of wire out of your wire feeder and see which way the wire flips over. It should flip over in the direction of your bore welder or point to your bore welder I mean

عمل رائع 👏 جدا شكرا لك

Don't know if any of that wire flip stuff makes sense to you, but when it welds up one bore completely fine and then you move over to another bore and the wire flip is completely terrible, you'll ask yourself why. And the reason is it's because you moved your wire feeder in a different spot relative to the bore welder. And once you find out where that spot is where there is no flip, that is where the wire feeder sits every single time it'll never change.

When you see a bore wallowed out that bad, it usually indicates the bore was not designed correctly for the load - even with the bushing. That bore has to be at least another 25%" wider to handle the extreme loads

I'm always amazed by the negligence of the operator, like how in the fook gets to this point???😵😵😵😵

Catywompus is the correct term to describe the oval pin holes

Enjoyed

Sitting in front of your computer look up motor mounts 2122 and 2123. Think of a using those with some bolts and washers to create harmonic dampeners that could be screwed into different threaded holds in your boring bar and be crazy easy to remove or shift to a different location. I worry about your support bearings. About the hydraulic drive unit bearings. The vibration must be vibrating the bearing races and balls.

Hello. please tell me the brand of records you sharpen welding. Thank you

👍

And if Earl Scheib was still alive - I'll paint any OFW repair for $99.95 :)

Love the bore alignment videos. Is that mill hydraulically operated?

Had allot of people mention you on my channel How do you like the climax Any experience with others? We do some line boring but maybe once a month Great videos!

Bon Boulo😆😆👍👍

Beauty

👌👍

Did you find a crack in the top hole? Most fascinating part of the whole job for me is the bore welding. Thanks for taking us along.

Another great video!! Have you gotten much use out of that new airspace on your truck yet?

Wire flip isn't fun. Be behind your bore welder looking at it, have the bore welder rotating clockwise, then have the wire feeding conduit come out and go to your right And make a right angle to your bore welder. And have the wire feeder conduit up about level with the bore welder. It only took me 15 years to figure that out. But it does talk about it in the book as well. You might have to try a different configuration on where your wire feeder is sitting, but that's what worked for me. my wire feeder is a little different,

so let me ask this, if you use dual shield wire I do not need any gas?? Thank you for your feed back in advance.

🙌

What tool bit holders are you using, i still use the micro-100 bits, cant find any 1/2” holders that fit

What is the wire spec? Type, size, voltage and ipm? Thanks .. Running out of wire in the middle of the weld really makes it tough... Nice restart..

So these huge components are cast iron aren't they? Or cast in steel? I'm asking because cast iron is supposed to be a headache to weld yet you're building up the bore with MIG without any trouble or is there a steel sleeve in the larger iron casting and that's what you're working on? Anyway I don't repair Cat frames obviously but I'm really interested to know how this works

👍👍

Hate when I run out of wire

I work machines with out adjustments hammer and brass bar hope for the best? 😢

Do you ever use cutting fluid on your weld machineing with lathe,i would imagine it is a hard material ,cheers

Do have any videos of jobs done with the S Power machine? I only see the video of you unboxing it. Just curious if they're worth anything or just junk.

Very nice! From your videos I understand how line boring works in general, but it's still a total miracle to me that it works in practice - over time you've shown some parts that looked like you should have been able to get anything centered on them with how chewed up they were. A few questions if you don't mind: Did the suspected crack in the smaller bore turn out not to be a crack, or did it cut out just fine? Did you have to run dye on it? Hand-welding the last part of the oval was likely because cutting it out and welding it all back up all around the ID would take a lot more time and wire than pulling out the bar and doing it just in that spot? And that's a big chunk of metal, I'm sure Cat would love to sell the customer a new one, and the customer has thoughts about that idea! haha

How has the SPower unit worked out? I’m curious on purchasing one

I’m wondering, to get the alignment cones even further from the damaged area, couldn’t you have setup on the inside of both faces, where the damage is minimal?

So what material are those boring tips that's use to scrap away the metal made out of? That has to be insanely tough stuff.

I didn't realize you can make such a heavy cut on your cleaning cut.

The clamp-on digital height gauge for measuring the tool stick out on the line-boring machine is really cool. Is it something you assembled yourself from a bunch of parts? Or is it a standard tool that is available in the industry, as I have never seen one before :)

Awesome job like usual An adjustment screw on the backside of the cutter,sure would make things easier for fine adjustments and then use a set screw to clamp it On side note Greg, do you have preference with Miller welders over Lincoln and others? My very first welder was an old,old Hobart gas and that thing was slick, except for the carburetor 😂

So it appears the set up for your line borer is longer and more complicated that say CEE’s. I assume there are many machines to choose from. Is there a reason you chose this one? Great work as always! Thanks for all you do!

👌🏼🤘🏼🤘🏼

Nice video.. what brand is that stick out tool?

how often would you reckon you would need to true the boring bar when it wears?

I was hoping to see the new S Power system in use. Is that only for field work?

I highly recommend the Metabo Tapper GB 18 LTX BL Q I (602362840) CORDLESS TAPPER. I drill hundreds of taps a day and couldn’t live without this tool. Kinda pricey but not compared to similar. Thank you for the fantastic depth explanation. That did not look like a cheap tool either ;-) .

Have you ever looked into getting a face cutting tool? I've never seen you use one. Sir Meccanica has one that Cutting Edge showed today. Everything about the tool path is proper.

Where ypower machine ? Congratulation

have you tried your other line boring kit ? how is compared to a climax

Instead of a flapper wheel have you tried a cylinder hone?

Where did you get the tool measuring caliper

Is there a limit to how many times you can weld up and recut such openings? Thumbs Up!

When it starts to chatter on the faces usually the cutter speed is too fast,or tool out too far,or too much cutter contact.

have you done a job with the s power set up yet

Did that ever get any grease?
