Line Boring a CAT 349

Lets be honest here. The amount of skill that it took to hold the camera, watch the welder, and hit the arc interrupt button at the same is phenomenal. ;)

[@john9291]

this work looks complicated enough but to be doing it in the field and not in a workshop is very impressive

[@boogiewoogiebubbleboy2877]

I started watching your videos a few days ago when one poped up as a suggestion. It was you welding an earth mover which had developed a serious fuel leak deep inside one of the machine's arms. You cut out several large plates just to get to the leak and despite all the flames you successfully welded the many cracks, splits and replacement panels to seal up the tank once and for all. Brilliant job and much skill involved. I was impressed by the shear volume of different situations and problems you dealt with on site and in your workshop. I watched a few videos and subscribed because you do a lot more than set a machine to do your welding for you. I've watched three videos on line boring and this one is by far the most not just interesting but skilful because I had only seen complete revolution welding, but in this one, the borer welded the bottom part first bringing it to a level where full revolution welding was possible. That matchine is bloody marvellous. Your apprentice must be in his element because I would be if I were in his shoes.

[@frfrpr]

Your knowledge of the proper tools, such as the line borer, and skillset in using them properly in field conditions, and obtaining the precision to do such quality work is truly outstanding! You truly have my respect, and I want to express my sincere gratitude to you for making these videos! As a fairly new welder, out of welding school a year, I am learning so much from your expertise….thank you!

[@kkaunitz3700]

Interesting to see how others do the same kind of repairs. I did one of these in pretty similar shape. Thankfully they had the dog bone pins pulled to do a true bar to bar setup. I always weld up stand offs to put the big bearings on to keep the chatter down and take bigger cuts. I always do all the welding by hand with bigger wire too. Took about a 20 hour shift to knock it out from skimming out old bearings with air arc fixing grease lines and build up faces.

[@JustMike2791]

That's almost the exact line bore I use @ work. It's in a shop so we use the BB5000. It took me a few hours to get to know the machine years ago and it's super cake doing anything nowadays. Nice work, thanks very much for sharing. I do a lot of small articulating dock crane work for the fishing industry. Those guys beat those cranes to death before they say 'Uh...we better fix that.'

So they don't like preventative maintenance downtime? Let's put it off and have more downtime for longer later on. Short term foolish.

13:00. that is cool how the machine uses cams to control the amount of weld distance in PIE cut... .I thought it might be controlled by computer.......great looking job Greg......

[@exodustwelve2044]

There is so much more to this than people realize. The weld build up you don't want to be excessive because of machining time. And its best that finish isn't between layer's so peeling of the weld doesn't happen. Great job!!

[@mitchweber7868]

I would have thought that you would have to treat the metal somehow if you did something like this. This is fine the way it is, no heat treating or anything like that???

[@jimyeats]

@@mitchweber7868I don’t think you would need to per se. Since its a continuous weld surface on a single parent material. Plus there are bushings on top.

That is a very clever line welder, what with filling the "out of round" bottom of the hole and also being able to jump over the grease holes. The machine designers certainly thought about it. We are definitely an intelligent species. Great video.

Impressive. It's like 3D printing with metal. Those shavings at 32:40 are a beautiful blue color.

[@jamesbizs]

It’s not like 3D printing with metal… it’s literally 3D printing with metal. It’s additive manufacturing. Stuff like this has been around as long if not longer than 3D printing. This is the daddy of modern 3D printing. Also, they have actual metal 3D printing in the same format that you’re imagining.

[@Jonathan_Doe_]

Steel is pretty unique as metals go, it’s metallurgy/strength doesn’t get messed up as badly by repeated weld passes as other metals, which helps make repairs like this viable.

[@sonofadutchman9315]

I’m impressed with the Climax machine, does a great job and looks like it has come as a kit. The big blue box visible in the background. Almost all the lineboring equipment I see here in Australia is 3ph or homemade single phase. I note yours is hydraulic, Greg , I’d like to know why you selected hydraulic as the rotational force. Did the Climax come with its own power pack or did you adapt something else suitable? Regardless, it is a very tidy piece of equipment and does a good job. You’re a hand man to have around!

[@OFW]

The base Climax kit comes with a 120v electric motor. It’s okay, but the hydraulic has massive amounts of torque. Climax sells all the stuff to make it hydraulic.

[@jimsvideos7201]

Moral of this story: Don't let holes get that sloppy.

[@Fuzzy336]

Is the new metal that was added back by layering welds as strong as the original metal that was worn down from heavy use? Or will there be flaws in the new metal at a microscopic level that human eyes can't see unassisted that will result in this having to be done again sooner than it would on a new machine? I'm currently at my 3rd job related to metal fab, but I've only gotten to see welds related to sheet metal so I'd love to know the science behind this from anyone that knows!

[@OFW]

The weld is the same as the parent material. I don’t care how good anyone is, welding up a bore like this there will be flaws and small imperfections in the weld. But that isn’t really a big deal because the bushing is taking the load and it’s spread evenly over the bore.
