Always loved watching this process. During my apprenticeship at Tilbury Power Station there was a large crack found in one of our 60mw turbine steam chests. The top was removed and a pair of contractors came in to carry out the repair. I spent some time watching them and was really impressed. They said that they repaired a whole range of castings and showed me a ship’s propeller they’d stitched together. This was early1964.
Thanks for sharing Peter. This process has improved greatly on that method used in the 60's. Technology that saves! Thanks for watching and commenting.
Did not know you could fix a cracked casting like this. AMAZING! TH-cam is has purged so many people for "wrongthink"; all these older videos are now coming up on this dying platform. The algorithm struggles to find things of interest anymore. I am glad it found this video though.

I didn't realize this was a multi-video series. So, while watching the first video ("stitching" part), I was wondering how in the world are you repairing a crack by effectively enlarging it. This "locking" part answered my question. Super brilliant yet simple fixturing for the creation of that lock pattern.

I have just carried out two of these repairs on frost damaged vintage car engines. Both customers very very happy,so then so am I!. I pressure tested blocks after repair,perfect,not a bubble after hours of testing. Maybe some consider an expensive repair but try finding a cylinder block for a 1930,s Rolls Royce or a 1941 Alvis!. As an asides, it is a very satisfying process to carry out as an engineer. It's a neat and tidy start to finish job with a high level of personal satisfaction of a job well done, interesting to do and gets a brilliant reaction from customers! Makes you feel a little bit elite? A chance to show off what you can do and do very well?. It's the "yeah,I did that" feeling.
I can see it being used on something like that, or something that would be a couple 20 thousand dollars to replace. It looked like a section of boiler for home heating. That's why I question the time and cost. The labor to disassemble and reassemble a home boiler, in my opinion is wasted. I built my 1st boiler at 21 had to read all the directions, the 30 year old guys had never done it. It was great experience, freaking bull work, the sections we were told 280lbs each & there were 5. That 1 took me & 2 others, two and a half days. Back then about $2,500. That was 85. I have gotten much faster, probably did a half dozen over the years, most homes in my area have smaller boilers that are what they call package boilers. Anyway I got much faster, and today if I was still working. I would read the instructions on my time off probably online, just a quick brush up to speed things up. So today i would think i can disassemble one with interest in reassembling it in say 1/2 a day. Still need 2 guys. Then a whole day to reassemble it. Todays labor in the ballpark of $2,500. I would never do the weld. How much would would a new boiler be, and up to what % of the cost are you willing to spend on a used unit? It would be different for DIY's when you don't run a P&L sheet afterwards. The weld itself has to take half a day or more, depending on size. All those holes you have to hold the jig in place, you CAN'T make the hole off at all or the system will not work, everything has to be perfect, it has to be time consuming. An irreplaceable car engine, absolutely. A regular car engine, in my opinion absolutely not. Just not economically sound for me. I also have in my mind that what I'm fixing has a chance of happening again in a different location, because the whole piece has been under the same conditions for the same amount of time.
I was lucky enough to work in a house that had 5 old RR with running boards and that freaking beach ball headlights.. Some were taken apart because someone likes putzing with them. I so bad wanted to jump on the running boards and have a picture taken carrying a tommygun. I didn't do it, at that time i was just married my 2nd wife, i was so happy life was great i got out of control to the tune of 360lbs. I just looked at the cars and imagined.

I'm flabbergasted! Is there an aluminum version? I'm not sure I actually need it yet since I haven't found a crack. Or if it's even possible should I find one.
Hi this seems a great product. just wondering do you supply to the UK. I have a 1939 metal lathe I want to restore the back gear cover has cracked at the flange that the screw goes into and the part has come completely apart right where the hole is. will this work for such a problem like this were two piecies have cracked apart. hope you can help. who ever owned the lathe previously had try to weld it together and done a really bad job of it. I didn't notice the weld as it was completely covered in muck and didn't show up until I started cleaning all the muck and grease.
Mark thank you very much for reaching out to us on TH-cam to ask your repair questions. Can you kindly send detailed pictures of the crack to info@locknstitch.com and a customer service technician will be happy to help you!

Some say "why not just weld?" The answer is easy. Variations in wall thickness, internal casting stresses and uncertain composition of the metal. Old ,aged,and possibly contaminated cast iron is never a guaranteed weld. Lock-n-stitch is as close to guaranteed as you can get.
I've done all forms of welding, and was very good at welding cast iron (stick welding & TIG)...BUT, was never a sure thing, Even when doing similar pieces, results varied...90% good...10% not so much. While this is a tedious process I would use this on anything that was irreplaceable!
Dennis Faugh I totally agree. I have used eutectic arc rods, high nickel TIG rods etc and ,like you said,you can get good results a lot of the time,but never all of the time. I have tried many of the different adhesives,fillers and epoxies and had much the same results. The best thing is that using lock and stitch I can guarantee every job. I don't find it tedious,quite the opposite. It feels good to use old fashioned fitting skills that were perfected as an apprentice and putting them to use. At the end of the job you can look at it and you know the job is a good one!
Thank you for your comment and question Thomas. The pressure rating is tied to the thickness of the casting where the repair is. Restoring original operating pressure is our normal procedure. Repairs have been hydro tested as high as 1500 PSI in one inch thick cast iron. If you have any additional questions feel free to reach out to us directly info@locknstitch.com or 800/736-8261 (209/632-2345)

My late father did this job for 40 years for a UK company called Metalock, It originated I think in the oil fields of Texas, where the use of hot repair techniques was not an option due to risk of fire. The above video seems a little long winded compared to the sopeed mt dad worled at, often completing several yards of repair in a days work....
A target market for this is definitely commercial sections where down time waiting for a new part costs money. Get the motor going while your Expediter flys 110mph in the diamond lane getting the new part to you.
Most certainly - when time is money and a new casting will cost the customer valuable resources our team can arrive onsite to do the repair. Or if the damaged casting can not be replaced, it is one of a kind, perhaps a historical piece; the team can provide casting restoration services so the casting doesn't have to be a total loss. Big or small - casting repair is our passion and we are here to provide solutions!
I will probably never have to do a repair like this, but this is still pretty interesting to watch. I'm curious what kind of metal the pins and locks are made of, aluminum perhaps?
Thank goodness I had the patients to allow part 2 to start, as I thought that the repair was not complete. I wonder how many others just watched the first part then posted bad comments?
Fascinating. I'm not a mechanic or machinist...and, I don't have a cracked casting...but this was oddly satisfying. How long would you estimate this repair required, from start to finish? A ballpark estimate would be fine.
Every job depends on many variables, smaller repairs can take hours - larger more complex repairs can take days! Thanks for watching. If you ever wish to speak to our technicians they would be happy to answer additional questions for you 800/736-8261 209/632-2345 info@locknstitch.com

My guess would be the skill required to do this repair is much easier than tig. It can be done in the field, and it could be done in conditions that are too dirty for tig. Just a few things I would wager are factors, I'm just thinking off the top of my head.
This can be done by old, middle aged men who cant learn TIG welding and don't have energy and time to do advanced repair. Simple technique for simple people.

Very professional repair. Why not do it my way. Put a piece of copper or brass shim stock into the crack with some araldite and tap it in. Then flatten it down almost level. Install the head and then fill the coolant system with a tin of Holts wonder weld. NO, not any other make. Now run the engine to temperature and check the instructions on the tin. No problem anymore. No shim stock? Use a cut up Coke can. Did this on a friends Jag XJ6 and he sold it after 4 years with no problem with the repair. Never used any water. Works on iron heads as well!!. Usually you get away with just poring the Wonder Weld in the Rad. No dismantling that way and it works on BMW cracked heads as well.

WE NEED MORE FROM THIS SAME PERSON ON THE REST OF THIS CRACK FIX UP.
In which field of application would the need for this exist? Like in what types of machines are steel variants used that are unwelable?
I am more impressed you are still replying to comments on an 11 year old video. Now that’s service.
this makes me want to have something to fix with this method!

I love this! I had an old man in the 80s teach me how to do something similar for cast iron repair but with screws and was it time consuming!
I don't see this setup being time consuming at all
i wonder if dropping the locks in the freezer would help aid the interference fitment.
These videos are outstanding!
Please let me know from where i can buy Crack repair kit

I'm flabbergasted! Is there an aluminum version? I'm not sure I actually need it yet since I haven't found a crack. Or if it's even possible should I find one.
Hi this seems a great product. just wondering do you supply to the UK.
I have a 1939 metal lathe I want to restore the back gear cover has cracked at the flange that the screw goes into and the part has come completely apart right where the hole is. will this work for such a problem like this were two piecies have cracked apart. hope you can help.
who ever owned the lathe previously had try to weld it together and done a really bad job of it. I didn't notice the weld as it was completely covered in muck and didn't show up until I started cleaning all the muck and grease.
Mark thank you very much for reaching out to us on TH-cam to ask your repair questions. Can you kindly send detailed pictures of the crack to info@locknstitch.com and a customer service technician will be happy to help you!
Why am I seeing this? Why can't I stop watching?
Thanks for stopping by!
Very interesting video series and a great tool set and process. What are the advantages of this repair over, V grooving the crack and brazing or preheating and TIG welding the crack? Regards, Ash.
Permanent repair! Here is an article that can explain a bit more www.locknstitch.com/pdf/gmrc_white_paper.pdf

Yes cast iron repairs very nicely with brass or arc welder , last year I did a head Gasket on a 1947 tractor , I had brazed the head and block top in 1968 due to frost damage still fine 53 years on
Absolutely incredible. Marvellous stuff.
Amazing...where i can buy this product?....

I certainly will! :)
Some say "why not just weld?" The answer is easy. Variations in wall thickness, internal casting stresses and uncertain composition of the metal. Old ,aged,and possibly contaminated cast iron is never a guaranteed weld. Lock-n-stitch is as close to guaranteed as you can get.
Thank you for the comment Andrew and the support!
I've done all forms of welding, and was very good at welding cast iron (stick welding & TIG)...BUT, was never a sure thing, Even when doing similar pieces, results varied...90% good...10% not so much. While this is a tedious process I would use this on anything that was irreplaceable!
Dennis Faugh I totally agree. I have used eutectic arc rods, high nickel TIG rods etc and ,like you said,you can get good results a lot of the time,but never all of the time. I have tried many of the different adhesives,fillers and epoxies and had much the same results. The best thing is that using lock and stitch I can guarantee every job. I don't find it tedious,quite the opposite. It feels good to use old fashioned fitting skills that were perfected as an apprentice and putting them to use. At the end of the job you can look at it and you know the job is a good one!
I weld cast with 309 , I do drill before and after crack and spot stitch ,preheat and all other steps
A very interesting concept. I wonder what the pressure ratings would be on the repairs?
Thank you for your comment and question Thomas. The pressure rating is tied to the thickness of the casting where the repair is. Restoring original operating pressure is our normal procedure. Repairs have been hydro tested as high as 1500 PSI in one inch thick cast iron. If you have any additional questions feel free to reach out to us directly info@locknstitch.com or 800/736-8261 (209/632-2345)
Awesome video, your hands look familiar. My coworkers always wear gloves, nitrile or leather, but I always end up tearing them off. I need to feel the work. 🤷♂️
That glue must be something else.
Super detail
I don't know why this was recommended but it certainly was interesting.
We used to do this sort of thing back in the late 60`s. its called boilermakers stitch
And look at how it has evolved! Thanks for watching.
That is awesome whoever invented that is a genius
The kit to make this repair comes with all those things, drill bits.....etc..where can i buy it...thanks
it's almost like watching a Bob Ross video
That is great because we do say it is the 'Art of Metal Stitching' ~ Thanks for watching!
Put some happy little locks right here.
Wow,how the hell is my patch job on my old backhoe still holding?? (Main Boom crack) lol I promise I didn't do it like this,this is a awesome video!!
This man is the Bob Ross of machining.
He beat the devil out of it.
David, What happend to the last part of this video with the crack into the bolt hole?
that is what im wondering, that looked like a good way to get return customer for the wrong reason, and then usually have to repair at no cost.

Nice,even Jay Leno has one engine repaired with this method,I say is working.
Yes he does! We are so glad that he reached out to us. Thanks for stopping by and watching. If you are ever in need of our products or services do not hesitate to reach out to us info@locknstitch.com or 209/632-2345
I think its a beautiful system but unless its a diy project, how many hours does that take? How much would a new section cost?
This process can be used in many different applications, from smaller automotive engines to large industrial casting and large engines - the cost will vary on the complexity of the repair; if you have specific repair questions please feel free to email our customer service team info@locknstitch.com They can get you more information - Thanks for watching and commenting.
My late father did this job for 40 years for a UK company called Metalock, It originated I think in the oil fields of Texas, where the use of hot repair techniques was not an option due to risk of fire. The above video seems a little long winded compared to the sopeed mt dad worled at, often completing several yards of repair in a days work....
I think they are going slowly for the benefit of the viewer. Your Dad was doing it for a living, which encourages speedy work.
This is an amazing solution!
Thank you - we appreciate your feedback!
That's so satisfying post drilling!
A target market for this is definitely commercial sections where down time waiting for a new part costs money.
Get the motor going while your Expediter flys 110mph in the diamond lane getting the new part to you.
Most certainly - when time is money and a new casting will cost the customer valuable resources our team can arrive onsite to do the repair. Or if the damaged casting can not be replaced, it is one of a kind, perhaps a historical piece; the team can provide casting restoration services so the casting doesn't have to be a total loss. Big or small - casting repair is our passion and we are here to provide solutions!
So not knowing precisely what this is for, is this essentially to stop cracks widening and strengthening potentially weaknesses?
I will probably never have to do a repair like this, but this is still pretty interesting to watch. I'm curious what kind of metal the pins and locks are made of, aluminum perhaps?
doeas not look like aluminium. Besides aluminium locks will break up even during instalation.
Accidental asmr. Some good shit
Thank goodness I had the patients to allow part 2 to start, as I thought that the repair was not complete. I wonder how many others just watched the first part then posted bad comments?
What do patients have to do with it?
Fascinating. I'm not a mechanic or machinist...and, I don't have a cracked casting...but this was oddly satisfying. How long would you estimate this repair required, from start to finish? A ballpark estimate would be fine.
Every job depends on many variables, smaller repairs can take hours - larger more complex repairs can take days! Thanks for watching. If you ever wish to speak to our technicians they would be happy to answer additional questions for you 800/736-8261 209/632-2345 info@locknstitch.com
Thank you for the thoughtful and informative reply. I actually do know someone that may benefit from your remarkable product. I will e-mail them your contact information. They have an issue with an engine, though I'm scant on details. I saw Jay Leno mentioned your product and company in his video about his 1930 Indian Chief motorcycle. Congratulations. What an ingenious product/technology.
@@karlhungus5554 That is wonderful! We are very passionate about casting repair and we truly enjoy having such wonderful feedback. Thank you for passing on the information to someone in need.
@@LOCKNSTITCH The repair in the video could have taken only a few hours. Those gigs are invaluable!
the welding machine, sent a hug
where the hell do you get that air spray!! i mean it has a blower on the side and a fitting on the top!! genius!!!!
They are fabulous aren't they! You can buy them from us! LQA is the part number 800/736-8261 or 209/632-2345 or info@locknstitch.com
What about the rest of the crack? How do you seal that area up? If it’s a water jacket, it’ll leak like a sieve.
Did they do away with the crack finder and a black light and magnetic dust? I bet the crack goes way past where he think it goes?
Would a stitching screw at the end of the crack be beneficial?
Excellent thanks good job 🙏🌹👋💐👋🌹🙏
If it's good enough for Jay Leno, it's good enough for me.
Thank you Tom! We are passionate about casting repair and we truly appreciate you finding us after watching Jay Leno talk about our products and services.

May be a silly question but what are the advantages of doing this method versus TIG welding?
My guess would be the skill required to do this repair is much easier than tig. It can be done in the field, and it could be done in conditions that are too dirty for tig. Just a few things I would wager are factors, I'm just thinking off the top of my head.
This can be done by old, middle aged men who cant learn TIG welding and don't have energy and time to do advanced repair. Simple technique for simple people.
excelent vork! on that piece of material
Amazing job , what nice mecanic trick !!!
Vidéo très didacticiels .
Merci .
Solid suggestion. I never knew this was a thing. Looks expensive

Very professional repair. Why not do it my way. Put a piece of copper or brass shim stock into the crack with some araldite and tap it in. Then flatten it down almost level. Install the head and then fill the coolant system with a tin of Holts wonder weld. NO, not any other make. Now run the engine to temperature and check the instructions on the tin. No problem anymore. No shim stock? Use a cut up Coke can. Did this on a friends Jag XJ6 and he sold it after 4 years with no problem with the repair. Never used any water. Works on iron heads as well!!. Usually you get away with just poring the Wonder Weld in the Rad. No dismantling that way and it works on BMW cracked heads as well.
Or just oxy/ace braze the crack shut and dress back.
Gives another option other than welding or brazing.Does this work on a curved surface or only flat surface though?
On subtle curves you can just grind or machine it down but on anything else you'd need to braze
