I like watching Allistair, Isaac and Kurtis because they do not indulge in re-ra bullshit and lengthy repetitive "introductions". They just show the problem, briefly explain the plan of attack then straight into it. Allistair, your present fix-it was similar to Isaac's latest poser, a seriously broken 'banana'!

Your boring mill and gantry crane are bigger then mine but so are your projects. I love seeing the heavy stuff. 🙂

[@davidmunro1469]

Thank you for sharing. Excellent repair. I watch every😊welder to get new ideas.

[@kaydog2008]

We sure don't have many shops like yours left here in the U.S. They've all but a few have gone with the dinosaurs. Cause we have so many independent on sight welders with rigs who can almost do it all. With the exception of the HUGE mines. Who have their own repair shops.⭐⭐⭐⭐⭐Repair job there.

[@garyyorke1080]

Always a good content and you never dissappoint. Great idea as you say make it thicker but if you keep upgrading everything your gonna run outta diggers to repair ..I'm sure there will be another boring task soon to show off the little boring tooling you have ..lol..

New subscriber and I love the heavy engineering shop you work in.

[@rs2024-s4u]

Great result too bad the no shots/video of large mill making milling/drilling for what normally be line boring look easy, if you have a large enough mill and can position the broken part correctly it's a routine piece/segment of the entire repair process. Nice fabrication of replacement boom segment new piece looks to be much more robust and better made than OEM. Ray

[@summersoldier3311]

Dang, you've gone big time with the gantry crane and 120 ton boring machine!

[@kwinterburn]

That's an interesting failure, it's a "peel" failure, the location of the brackets compared to the sides causes the pull from the ram stress to peel the welds apart which caused the failure of the Derbyshire ship.i believe

[@jamesriordan3494]

Well done and thank you for sharing !

[@stuartlockwood9645]

Hi Alister 😊 nice job mate, real neat welds, is that from a new type of mig,? Pitty we didn't see the little boring machine in action, looked like the whole floor area in front of it is a T slot bed , massive. Thanks for another interesting video mate, stay safe, best wishe's to you and your's, Stuart UK.

[@spotweld]

One of the unsung heroes who helps keep the world run..👍

[@bobanppvc]

Other way is to use two boring bars.One at good hole centered and measure to second that need to be fixed..You need to make linete for second bar to adjust it

[@davidallinson2501]

Surprised you don't do more bevelling type weld preparation to get more complete penetration and rely totally on fillet welds. Guess it must work as keep on just using fillets!!! You and Kurt's do a great job. Thanks. David in Spain.

[@allistairc123]

Check out my other welding videos lol....

[@pinchface]

Can you explain the copper rod more please?

[@catabaticanabatic3800]

You can run the weld out onto it thus ensuring good continuity of weld thickness and a better termination. The deposited metal will not weld to the copper, the copper will fall away when the clamps are removed.

[@pinchface]

@@catabaticanabatic3800 thanks, I've seen it done with little tabs of steel but never copper bar!

Great work .. nice and Heavy duty now only problem is might not break again no more work for you ,, LOL they will find a way to break it again if they did that the 1st time .. they compressed the old rail that holds the ram it was cut and that big gap .. do they watch there machine when digging ?? or is it when it cracks it just peels and bends fast ??

[@beyondmiddleagedman7240]

Beautiful welds! I'm jealous. I'm going to assume that the (looks like a) huge, long crack on the side plate from top to middle wasn't a crack. Since you didn't gouge it out and weld it up.

[@506curtis]

Another beautiful job. Dang you guys have some big equipment. I love it!

[@keltonwright7]

Why did you only put one pass on the lugs? not do a triple pass type weld?

[@tobystokes7366]

4:54 - sorry if it’s an obvious question but you put “copper bar for root weld” … what does that mean.?

[@brucejenner5856]

It acts as a non- fusible back up to stop the weld blowing through

Another awesome repair! You and the company you work for do incredible work. I can't get enough of your videos. I have a question. When I was watching the first cut, I immediately thought: "He's cutting it there because that's where the bent plate stops. He will drop it down where it belongs and re-weld it there." When you completed the cut, it almost fell into place. So I was very surprised when everything was replaced. It just seemed like way over-kill. I realize that you probably don't make all the decisions on how something is repaired, but I was just wondering why. I'm sure I'm missing something. Thanks

[@allistairc123]

The little bit at the bottom of the lugs were bent where plate was cut and the plate had a delamination cracking before it broke to the plate had to be changed anyway so instead of trying to straighten bent lugs and have to reweld them to new plate was just as easy as make new ones saved cutting them off cleaning them up straightening them. Definitely could have saved them if didnt have the options but it was one or the other
