emergency metal removal thermal Lance style 

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!

45 years in the trade. I just wish we had the breathing apparatus of today. I'm now 70 years old and breathing is a hard job. I miss the smell. Newbies . . . always wear your air filters.

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

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

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

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!

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

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

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

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

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

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

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

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

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

always good to see somebody honing there thermic lance skills,

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

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

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

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

Fire and ice! Thanks for taking us along !

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

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

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

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

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.

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

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

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

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 😂

Fantastic work, looked like a hell of a job!

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

Congrats on the new edition to the house hold.

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

Awesome job. Thanks for taking us along.

Interesting job, a good old handmade thumbs up.

Nice delicate work on a giant workpiece.

Thanks for showing, incredible work!

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

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

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

What is it though? Quarry rock grinder/crusher thing

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

I worked for RICHARD FOUNDRIES in Norfolk Va USA. In the 60's. It was hot and hard work, I have respect for your ability 😃😃😃 GREAT job with no damage !!! Thanks

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

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

Nice job. Serious work

Great video keep them coming

used to love lancing. and watching the boss ask others who wanted to do the job and seeing them run as if they were scared of getting a blister

Cooke bro's rule again. Amazing place.

You do some high end manufacturing, nice work

Enjoy these videos , from The gouging to the science behind expansion is specialist work 👍🏻 Please continue to upload content like this congratulations on the baby 🎉

Awesome work Allistar ye have some set up there

I did electrical work at a foundry and they would occasionally use a thermal lance. Scary that you have to light it with an oxyacetylene torch.

That's an Oxylance. If you wanna see Hollywood make those look badass...watch Thief from 1981. Badass movie.

I know the process, but this is really big,big;big scale,verry good video,thanks,greetings from Antwerp Belguim.

what an awesome video ! and you having or better making the time to video record all of this ... I did a few job similar to this, only 2 I recorded and put on my channel ... the others I had to do what I had to do and get ti done and the customer did not want his faulty shown .. etc etc etc ... GREAT JOB !

Congratulations on your new arrival. And thanks for the video awesome work my friend. From up ,t, north. Rochdale nr Manchester

This is so cool. I have worked with this back in 2005. At Akers Sweden. I allso was a lathe operator. We turend rolls as big as 69 tons.

I use this process to assist with the removal of seized pins when disassembling mining equipment. comes in very handy and is a real easy way to get burnt

How is lancing more cost effective than drilling and milling the shaft out?

Wicked awesome video, please keep them coming.

I'll bet the bugger thing is still warm, too.

i use work with 1.5m long torch harris and the tip was nh5.about 12 to 14 bar.

Beautiful work sir. And I thought cutting through train track was thick.

Very, very interesting stuff and very impressive which makes for a briliant video. Well done on the success of the job. Looking forward to the future videos!

Incredible effort

''Unplanned event'' fuck that was funny

wonder how many oxygen bottles were used for this job and the cost of the oxygen used. at the start the sparks and molten metal is bouncing back at the operator. oh what fun

Expansion of the hole… Shrinkage of the shaft… Story of my life…

Very cool ,,, DId you know metal continues to get harder as you cool it ?

I’ve seen big bearings, but I haven’t seen a pallet sized roller bearing before. Big machines require big components!

Id love to leave the motor trade and take on stuff like this, absolutely amazing your content 👌🏻

Serious job Alistair 👌👌 love these videos

How much does one of those rods cost? There is no way thats not expensive!

Now thats bloody extreme engineering - wow Monster Job? Colossal Job!!! If the Axel/ Shaft /Pin or what ever the something of that scale is called is £10’000 how much do you charge? Also do they recycle the slag because essentially it is a feedstock for steel making, thermite process, pottery etc…..Iron Oxide & Nitrides……? 👌👌👌👌😞

do you mean there is no way to remove the shaft hydraulically

maybe i missed something in the video.. is a thermal lance some kind of thermite torch?

I would have liked to see it installed in real time. What was the necessary delta between the OD of the shaft and the bore?

Brown fumes... it is nitrogen dioxide. Damn, the temperature of cut is enormous.

This is what they do in the movie 'Thief', right?

Nice job man👍😎

Great work. This is a rock crusher?

That slow mo audio though :D

Looks like a cone crusher ?

why dont you guys use a car battery and alligator jumper wires to start the lances with? much faster more portable and less time and waste than using the blowtorch i would imagine, so the hole bored in the shaft allows room for it to shrink in diameter once cooled and therefore able to hammer slide it out right? btw very nice shots thank you for making the vid

what kind of a fit is it?, what are the tolerance? for example if you hole size is 1.000"+.020-.000 ID would your pin dia be slightly larger in the thousands by what tolerance at room temp for that specific fit as example?

What is that peice of equiment he is working on?

Your skill level is unbelievable 👏👏

Amazing workmanship - thanks for sharing. If you don't mind I have some questions: *Was one bank of oxygen cylinders enough? *What are your overalls made from (boots caught fire, but not the overalls)? *How long did it take to finally warm back up to ambient temperature? Thanks again.

"Backyard mechanics" lol more like extreme engineering.

Doing that liquid nitrogen stuff indoors is very dangerous

grand job

Great Vid 👍👍👍👍👍💖💖💖💖📐📐📐📐💪💪💪

How does that plastic on that respiration system hold up in all that?

Got a light?

Fair play that’s proper impressive!

Very interesting m8 thanks for the video

How many hours of cutting did this represent?
