Fantastic! A rare insight into not just thermic lancing but also the rebuild process. A rare video here on KZfaq and done in a higher quality too. A huge thank you for sharing this.

As a mechanical engineer this was fun to watch because we only see the technical and rarely see the actual work being performed. Great job.

Both my Dad and I spent a lot of our careers in heavy industrial engineering. Dad has passed on now, but I can tell you he would have loved this video. I can remember him enthusing to me about shrink fitting long long ago when I must have been all of 9 years old. Well done! An immensely enjoyable and brought back a lot of precious memories. I was left to discover thermic lancing during my career, while looking after a small design office in the Local Authority's water pipe fabrication and maintenance depot. Some contractor had the idea that we could quickly cut 1.9m diameter concrete lined steel bulk water pipe and we arranged for him to come and demonstrate on an offcut. I can remember what a mess it made of the 12mm thick pipe. I am pretty sure that the 25mm concrete lining and some of the concrete slab under the offcut actually melted as well! We decided not to offer them work but we all had a wonderful afternoon. What's more, it was Friday! Engineering doesn't get any better than this! :-) Great video, thank you!

Heard lots of stories about thermal lances, never seen one in action... Fascinating... and I jump about when a tiny spatter off the MIG lands in my boot... Legendary!

As a ships plater I’ve used up to a 25 gouging and 1/8” cutting nozzle, top skills my man!👌👍👌 chasing that black line n kissing the bore is an ability learned only from experience. Your camera work is A1 too, waaay better than any training video any college has ever sent us to sleep with! The link to explain the thing is a cool touch as well.

this video makes me very so very happy that SCBA have become popular with metal workers. I'm not that old but 20 years ago I never saw them in any shop, just literally had to turn our heads and hold our breath when the bad smoke came out. Just the soot from a normal day in the shop coats the bathtub in a black ring, I can't imagine how bad it is to burn through nearly 3 cubic feet of steel like that. Drink some milk if you burned a lot of galvy everyone used to say. Yay for reasonable safety!

Great to see a thermal lance in operation again! 50 years ago when I worked in a stone quarry as a fitter, my welder colleague made one using a small diameter mild steel pipe with no rods in it! We had to cut a hole through heavily reinforced concrete wall. Went through like butter! Always wanted to try it, but I never got the chance!

Amazing precision and accuracy, especially on such a scale. I'm sure the satisfaction and relief when the shaft went all the way in was enormous. Thanks for sharing.

3 E's: Extremely Entertaining and Educational, thanks for making the film.

I am impressed that you manage to cut that close without damaging the bore , well done....

He says “ya that’s pretty much it, job done” like there was nothing to it. Absolutely amazing

That was absolutely awesome! This is the kind of work that makes the modern world a reality. Most people don't have a clue.

You are like a surgeon with that lance Great to see the process

Makes my bench top mill look like something you would find in a cereal pack and attach your keys to

You are a special breed of man to tackle that job. Fascinating to watch.

We used a lance with special metal rods inside to cut a large manhole in a 24" thick concrete wall back in 1968. Quite a thing to watch for an 18 year old kid just starting out in the mining industry. jack

Such amazing skill. How anyone can be accurate in cutting with a thermal lance beggars belief, Well done, excellent video!

I love the explanations - but you tend to cut yourself off. I for one love to hear all the details of this kind of work. This is huge stuff.

Dropped a fair amount of liners in my time but never a shaft of that size. Damn good job.

always good to see somebody honing there thermic lance skills,

Absolutely amazing work, the precision with such huge parts is really impressive. The thermal mass in that shaft is incredible.. rather you than me with the pressure of shink fitting that one though lol. Love the videos and thank you for taking the time to make them

Great to see some real heave engineering still being done in this country... 👍

What a fantastic process. I’m a first year apprentice fitter/turner. I can only imagine this sort of work. Thumbs up for sure 👍

Did some of this lance work , burning out large pins on old equipment and 'chasing the black line'. Excellent work! Tops!

It's weird to see metal flowing like water. Thanks for the shot with the visor.

Awesome video, we use a thermal lance to remove seized pins on heavy equipment, works great

That was really fascinating to see, I have heard of that type of cutting steel but wow that's some hot work lol

When He leaps amidst us with combustive dance All shall bear the branding of his thermal lance

Fire and ice! Thanks for taking us along !

A thermal lance look like a violent portable volcanic eruption, but they be used very precise with the right craftsmanship.

Jeez ! Extreme stuff to get those pieces out. I'd have tried WD40 a couple of times, DOH !

We've had our Terex down far enough to replace the cone and liner, but never seen one naked to the casting. What have I learned ... I'm retiring before the main shaft needs burned out.

I wish to thank you for sharing this video as I have never thought of, nor have I ever seen anything like this, on this scale before. The mix of the sheer size and weight of components, the tools used, the solutions applied, the more than excellent precision required, makes me utterly impressed!

Done a a cracking job with the lance, it's very difficult to be that precise not to eat into your bore. The part fitting the new axle was also fun to watch, true heavy engineering.

Big Alistair at it again lol.... superb video as always buddy...congrats on the new baby bud...you got so many skills dude and balls of steel to boot what a man ..thanks for sharing with us buddy ....peace n love from Cumbria uk

I worked at a machine shop where we could swing 8 feet. I thought *that* was impressive. That is one monster mill.

When I bitch and moan about how hard my job is.....I watched this and thought......what a little cry baby I am ... Nice video...thanks for taking your time to make them . Truly enjoy your channel, but deeply respect your talents and skills. 👍

You guys are amazing at what you attempt to do, and accomplish.

i loved the Backyard mechanics comment , i assume it was a nod to the late great Sir Fred Dibnah. keep up the great work.

Brilliant subject. Always wondered about their mic lances. Great video.

You folks did a wonderful job on a real PITA repair! Thank you very much for sharing

I would bet AvE would love seeing this kind or Stuff!

I enjoyed it so much I had to watch it again! Thank you!

Boring mill with a ladder 😮 great video, fascinating stuff. Congratulations on the little’un.

Incredible video I’ve never seen anything like that before. Really appreciate you doing this.

Thats badass, keep it up man.

Nice job no one sees the omount of work sweat that took in 20min video great job those lances are amazing didn't even scratch that bore great job

Awesome video, your little one is going to be fascinated when he grows up and you watch this together!

Awesome job. Thanks for taking us along.

New to the channel. I really enjoyed this massive refit. People really don't understand the efforts that are made to keep this industrial world going. Thanks and congratulations on the addition to the family.

Love this content! Where else would you learn about a process like this.

Fantastic video. Thank you for spending the time recording and editing it.

Wow, that whole process was incredible!! Thanks for entertaining me for a while, I appreciate it!

Nice delicate work on a giant workpiece.

Quite a repair facility you folks have there. Must be nice to have the machining capability at your disposal. Big job for sure. I have been involved at times in all of that stuff except the VBM work, albeit on a much smaller scale. Not easy work for sure, but slow and steady wins the race and prevents unexpected, shall we say....stoppages. Big ole thumbs up, cheers and congrats on new addition to family. 👍👍🍻

Big thumbs up fella that was awesome , not seen a thermal lance actually being used in something this size . Congratulations with the little one it's more time consuming than having a job . Thanks

Can't see enough of videos like this one. VERY impressive!

Excellent job can't wait to see the next heavy duty welding project 👍👍👍👍👍👍👍👍

Most informative and interesting. I appreciate the time and effort you put into editing clips and compiling a video, especially with the (delightful) extra demands now being made on your time! Col, NZ

Congratulations on the new baby boy. You do amazing work on massive equipment. Question: On the first cut that ended in an angle, is it possible to put a radius bend on a cutting Lance allowing you to attack it at more of a 90° angle?

What a great great job. !!!! Once again you have demonstrated how old guys move mountains. !! I’m also one of those old guys. Keep up the tremendous work that you post.

Brilliant to see that in detail and explained and would be great to see the next stuff in the pipeline 👍👍👍 I did laugh when the boots caught fire too, got a good chuckle from that. Did something similar on a gas forge when a chip fell out and didnt notice it until stood on it and the plumes of thick white smoke erupted from the underside of my boot! Usually its fellas in shipyards or scrapyards and grainy footage you can't make out but this would easily be the best video on youtube of someone using a lance and explaining it along the way and showing the results etc.

Really enjoyed the video Allistair ,keep them up when you can. 👍

Excellent video! Keep up the awesome work and congrats on the new little one!

Thanks for showing, incredible work!

Wow talk about thermal mass!! the fact that housing was heated and everything is still frozen 5hrs after installation just goes to show. Awesome job to to see being carried out though, I'm a machinist/engine reconditioner but I had to step out not long in to my career due to medical issues. but I do miss making chips I was only doing "heavy" diesel engines mainly 3500 series cat , 4000 series mtu ect but this stuff makes them look like light vehicle engines in size comparison 😂

7:11 according to those forklift hangers, you've lifted some heavy shit with that thing.

Great video. The size and scale of the jobs you do is amazing.

really cool that the vid shows installation of the new shaft. great vids of guys gettin things done!

That has to be one of the most satisfying jobs I've seen , thanks for bringing it to us.

Nice job man! Impressive boring machine too, damn. Huge!

Interesting job, a good old handmade thumbs up.

Fantastic work, looked like a hell of a job!

Wow this channel certainly lives up to its name you are certainly the BOSS!

Congrats an thanks for this great content and also for bringing a new lad into the family, wonder if he'll follow in his dad's footsteps :)

Fascinating work! Can't imagine how hot it gets! Thumbs way up! Great job!

Congratulations on your new boy! And a massive job done right. Cheers. 🇨🇦

Shrinking shafts can be a nightmare , in your head the fear that it will go tits up and stick half way , just out of interest what was the interference size of the shaft to the bore, and how much did it contract after the Nitrogen bath . cheers .

Well done my man!!..Spot on job by a quality tradesman. If ever there was a job of irony, this is it.

Congrats on the baby boy... love your content, been missing you.

When you first started, how terrifying was it to use the lance and have metal spray up back at you?

Love doing a bit of lancing ( not on that scale) Was there any oxygen left in the bank. Keep up the great videos 👍👍👍👍

that slag pile looks like a sculpture......great Video Sir.....thanks for sharing...Paul

Alistair you have the coolest and hottest job in the entire world - Thanks for sharing it with us. I worked for 20 years as a radar and wide band communications technician for NORAD aka The United States Airforce 4700 OSS wing specifically formulated for the DEWLINE, Distant Early Warning Line, in the High Arctic from Alaska, across the top of Canada, Newfoundland & Labrador, Greenland, Iceland all the way to England. The DEWLINE consisted of a chain made up of more than 60 manned radar installations. I had a rare and interesting Top Secret job but I think your job tops mine ... love your videos Alistair and am a loyal fan.

Good job, thanks for taking us along. Done & Dusted

Pretty precision work using a lance and then a cutting torch. I’m amazed to see that there’s no damage at all to the main housing.

Great video keep them coming

Very cool video. Never heard of this type of process before

It’s crazy how strong we think some things are and when we use the right tool they might as well be wet tissue paper but sometimes when you don’t have the right tool you get reminded that it’s still very strong

expansion of the hole and shrinkage of the shaft sounds like a marriage to me

I love seeing machinery that's done on a different scale.

Great job mate, good to see. Keep them videos coming.

Congrats on the new edition to the house hold.

Oh wow, the timing on this recommendation I literally helped on a rush job for an identical-looking part

Man That was a clean burn. Well done.

Another awesome video. Now that is what I call heavy engineering to the extremes. Would love to play with one of those thermal lances one day. Hopefully I might get the chance to but not sure how I going to fare going back to work as I'm having to have my leg amputated now. Still, I'm sure ill get back to work eventually and if ever I'm up your neck of the woods I'll swing by and say hello. Many congratulations on the new baby.

You definitely earn your money!! A job well done.

So from scale replica machinery to scale models of the Sun and Neptune. Awesome,

im a women and i really appreciate your videos but leaves me sad cuz i cant play but i wanna play. im a little industrious and amazed at some of the shit i have to come up with on the fly but you guys knocked out of the park wow. am amazed . love your videos thank you

Great job Like working on the big stuff you did a great job cutting
