I am just an old mechanic, retired a few years back from my now 92. Many time during my career, I had wished to have grown from childhood as some I have known, who learned as apprentice in their professional parent's machine shop. I highly admire the skill diplayed here, and compliment much this consciensious professional. Bless him in his work, and may he be ever successful and admired and emulated. Just plain Fritz
I'm a retired jewellery polisher and love to watch skilled folks working through problems. I always feel one step closer to God when viewing the very best that humanity has to offer.
I'm glad almost 2 years later this video is getting a lot of attention. These processes are VERY interesting and amazing to see. thanks for filming this!
Hi, I am a retired Eutectic Sales Manager. I thoroughly enjoyed your video and it brought back a lot of memories, especially the one's where I trained engineers in Africa on the benefit's of investing in this technology. We live in a throw away world, and when we see a worn part it's easy to go and buy a new one. Invariably, the part that's worn only represents 5% of the total part, so we are actually throwing away our own money! It really is a simple piece of kit to use, and like you say, just follow the instructions. Glad to see someone still using the Rototec system.
The company I work for we sent out equipment parts to "professional renewal shops" and have never had a piece come back anywhere near as nice as that one you just did. That's the difference in a big company and a man who takes pride in his work. Be proud in your work sir because it is beautiful...
What do I know about spray welding? A tiny amount. What do I know about using a lathe? A tiny amount. Do I enjoy watching a craftsman do his work? A huge amount. Thanks for sharing your knowledge and skills, you have a easy style that makes it interesting and informative. Proper 😀
Back in the late 1970's the Aussie army was using this method to repair worm drive sprockets on M113 APCs and the finished repair was harder and wore better than the brand new replacement parts. If i remember the repaired parts would last 3 times the brand new ones this was because they were able to put a harder build up on the wear area of the sprocket to the cast hardness
@@paulhickey4485 same process basically. But uses a wet oil fed quenching clamp with hardening oil on it . Spray weld , then immediately apply the clamp on just the area that needs hardened on the shafts or race areas. Saw this done at rayethon before on sealed drive motor systems in the 90s that were used in areas that were very inaccessible, high heat or that needed extreme long life intervals, (years) between servicing. New build process. Not repair like this as far as I know. But may have been used for rebuilding.
Hi, really enjoy watching your videos here in Scotland! Hope you don't mind me making a couple of comments - I worked for Castolin Eutectic for 30+ years and trained oxy fuel thermal spray system users. First observation relates to use of screw threading for preparation - I have never used this as a prep method for a couple of reasons. The potential benefit of screw threading is to increase the effective surface area available for the coating, but there are some factors that can limit this effectiveness. 1. unless the threading is done correctly (ie. rounded tip and root profiles) there is a risk of heat oxidising the tips of the threads which will reduce or prevent effective adhesion of the bond coat. 2. If the thread pitch is too narrow in the root there may be voids, again reducing the effective area available for adhesion. 3. Threading preparation normally omits what for me is another vital step (which may answer questions raised by some of your other viewers regarding causes of coatings shelling) - oxidation forming during the preheat stage. One of the key reasons for coating failure at the initial stage in my experience is applying bond coat on top of a surface that became oxidised during preheat. This is normally indicated by surface discolouration, usually evidenced immediately on applying heat. This is diffucult to see on a screw threaded surface, but becomes very visible if alternative preparation methods are used. So, I normally advise preheating, then final preparation. This is easier to do if it is possible to a, grit blast or b. random grind with a small grinder (with a clean disk). Step b. is usually easier since the initial set up of the part doesn't need to be disturbed. The clean, random ground surface is ideal for applying the bond coat to - but preheat, final light grind back to clean metal and immediately apply the bond coat. It would be worth trying this method, what you should see on applying heat is the formation of a brown discolouration on the surface - coating on top of this (as is likely happening) is most likely compromising the coating bond effectiveness. Just give a final light grind back to bright metal and proceed from there. Hope this helps!
If I recall correctly,we were told. To use a 90 degree too tip to cut the thread so that the root and crest of the threads were broad, and were therefore more resistant to overheating.
Couple of things First Wonka wants his giggles back Next, most impressive, three cameras on the spray welding, amazing!! Lastly ... Abom79, a family production!!
Working in a machine shop in the early 80's, I watched this process being done. I was awestruck by this. It saved the customer a ton of cash. Thanks, I haven't seen this process being done since then. Great job.
In the 1950s I was a 17 year old machinist mate in the after engineroom of the USS Kearsarge, CVA33, an Essex class aircraft carrier. Because I was rated (schooled), I was allowed access to the ship’s machine shop where I developed skills with a lathe and even a shaper. All the guys in this compartment were old salts and mostly interested in lounging and drinking coffee, but I loved making things here when I was not on duty in the engineroom. I began getting jobs making aircraft parts and things for the two galleys. Loved it all. I used many of these skills later when I became a jeweler. You seem like me in the sense you obviously love and enjoy your work. I was NEVER close to being as good as you, though. Thanks for the channel.
I am a fabricator / mechanic in the pharmaceutical industry. We have had great success with having this repair method done on several of our damaged bearing journals over the years. The company we use has been doing this for many years and I thank you for such an excellent explanation and video demonstration . Nothing like seeing it done in detail to fully understand and appreciate what is involved in it.
Quality of craftsmanship at its finest.. I'm a machinist myself by trade and this is a lost art rarely seen or done due to Advanced Machinery that can spit out parts at a mass rate .but Robotic machines like that dont put blood sweat and tears into there work. thank you for sharing your knowledge and inspiration for the industry . thank you for sharing your talent with all of us out there ..vary much appreciated respect that's all I have to say
That gentleman is nothing less than a precision craftsman with the pure genius ability to always do a job better than right. I love watching precision artisans apply their highly specialized craft. Thank you for sharing your exceptional work and skill.
Don't know about anyone else, but the thought of being able to save pieces that are hard to come by/no longer available (rare crankshafts, input and output shafts, etc) is why I love the spray welding so much. Congrats on 300!
As an electrical engineer, I had little experience in the machine shop. I tip my hat to you sir! It is so refreshing to see a man who knows exactly what he is doing and why. I saw you measure 3 times. Boy oh boy, what are perfectionist you are.
To see a true craftsman take this kind of pride in his work, makes him more than just a machinist, he's an artisan. This is a true art form in metal. Thanks for taking the time to show the entire process.
Love that this type of repair is carried on by displaying it on TH-cam. Techniques like this used by industrial craftsmen of the past are being lost in today's service oriented throw away society.
To all who may read this comment: I've been working with machinists for 30+ years. Very few will use this process. Most will lathe the original work piece smaller and then add an additional piece of material/metal. Spray welding is an art. This video is the mark of a MASTER. 'nuff said.
Thank you for taking me back down memory lane. I sprayed thousands of parts back in the seventies. Started off at 18 as a sandblaster. Worked my way up to metalizing, thermospraying and then to plasma spraying. I enjoyed those years working in that machine shop.
I dont understand why anyone would thumbs down this video I got nothing but complete and utterly satisfaction from this video...you dont see many good machinists anymore, oldschool skill is slowly fading away with today's technology.
Jared Simpson, I don't think they thumbs down due to video quality. My best guess is that they just don't want this type of content to show up in their recomendations? I agree with you that this was a great video. 👍
I can't speak to all your viewers, but speaking for myself, this is a hell of an interesting process and I'll never get tired of watching you spray weld.
I am a retired Machinist/ Toolmaker of 45 years and I must say you are doing one fine job. It’s nice to see some people still have what it takes, common sense, patience, and perseverance. Well done!
As an apprentice millwright, I find that many tradesman go the extra mile to do a good job. Settling for nothing but the best way. Theres always a few hacks. Just take pride and ownership in your job and it will pay off every time, regardless of the industry you're employed in.
@Igor Stephonivich Crash not in a capitalist world. it's nice that capitalism is losing supporters as generations come and go. soon we will have all working people taking pride in their jobs. Sadly, the way it is now, people's pride and values can be easily bought off in a world where money is everything.
@@Ryzot - Capitalism is freedom to do your best, the better your product the more the reward. Some people like the state to take care of them and other people like to take care of themselves. You can not group all people as one kind, if you want to live in China, Cuba, North Korea, Venezuela, Finland, Germany, etc. go ahead but I'm staying right here, and loving it!
This is what YT is about for me. Not some silly ass influencers and their bullshit. I prefer watching content like that, with hardworking, skilled people at work!
You are a true craftsman. I’m an engineer and sometimes I feel like we get all the glory but it’s our manufacturing people that are truly amazing. God bless you sir
I am beyond impressed by your level of expertise and craftsmanship. Utterly fascinating seeing this hidden world. You are truly an awesome example as to why we should encourage young people to consider trade schools and the like.
Really nice job, it's good to see real tradesperson doing a proper job. I work in maintenance shop and it is very hard to find a good machinist. Keep up the good work!
I have to say that, if this one video is any indicator to me, you are a great machinist and an excellent teacher! You laid out all of the information in a logical way, took me step by step through the process, and showed me the end result. I have subscribed so that I can learn more.
What a pleasure to see a professional tradesman at work. Good onya mate. Such a thorough and beautiful job. Fantastic dialogue too, really well explained. I remember seeing the machinists do this when I was an apprentice mechanic in the 1970's. It was Eutectic Castolin equipment too. They sprayed crankshaft journals where the bearings had spun. Quite amazing. How tough is that shielding paint!
Working for Otis Elevator as a Service Manager in Richmond VA my repair crews would encounter a galled shaft on a worm gear shaft or other shaft. Due to maybe a failed bearing on very old elevator. Our vendor machine shops could spray weld the shaft then turn it beck to original diameter. This was in the mid to late 60’s . We had wonderful machine shop vendors who could fix just about anything made of steel or bronze. Great video .
Thank you for sharing with us. This is the kind of repairs Dad, Jack Karp, used to do for Commercial Fisherman in South Beach, OR. I hadn't seen this tool in many years. Reminded me of the 1980's, watching Dad do repairs for a good price, high quality & timely delivered to get them back to sea fishing. He could fix it better, quicker & cheaper. He liked his work to be perfect. I miss him.
Wow, this brings back some cool memories of when I worked as a machinist early 80s for a now defunct company, Beach Russ in Brooklyn, NY. We used to make vacuum pumps, smaller ones mostly for the food industry and the large ones for the US Navy. When the pumps would come back for rebuilds, I would repair the shafts in some of them using this very same method. Saved many shafts this way. I suppose, this technology was pretty innovative at the time. Amazing it is actually still being used. Great vid.
What I love about wasting time on TH-cam; you learn something you had no idea existed, and all of a sudden, you didn't waste any time, and you learned something that might come in handy someday!
Very good video! Back in the 1990s I had a 3" or 4" by about four foot long shaft repaired by spray weld, as far as I know it is still running 40 years later. It was a large blower fan (60 HP or larger) on an air handler, first we had some vibration, than it became a rumble and then we found the culprit. The worn shaft was spinning in the bearing. A new shaft would have been a lot more cost than the repair was and we also replaced the bearings.
Awesome job dude, I never came across watching a lathe in action ever since way back when I was in high school metal shop class. But this is way more advanced..... you have given that worn down shaft another chance at value, and prob. saved the owner a lot of $$$..... You are a true Craftsman, thank you for sharing the value of your trade.
Thank you for taking time out editing and sharing your craft , and all your knowledge, it’s absolute gold . I’m not a machinist I’m a artist , but I appreciate the technical craft. And the precision is addicting ..... This is people’s livelihoods and it’s also craftsmanship of highest degree and it’s art to me
It has been years since seeing this done, outstanding job! Was stationed on a TENDER in Norfolk, Va. from 1970 to 1973 as a Machinery Repairman 2nd Class. Our shop had about every type and size of machine you could imagine, in late 1972 we started doing metal spray on pump shafts in an attempt to shorten the turn around time, had pretty good success with it. Great video! Will back for more.
Outstanding work have not seen this in the UK since the 70s , people have signed up for the throw away society now, decreasing number of skilled people like this. Thank you for video.
I'm 75 today and if i could live my life over again id learn everything i could in machine shop works and Spary Weilding, beautiful work this guy does.
I'm not a welder of any sort. I have no aspirations to be a welder or machinist. But I've just watched this entire video to see a master craftsman at work.
True! I'm and IT guy and I love this!! :DD (but until I was 12 I helped my uncle every day with machining & repairing agricultural machines and cars/trucks)... Kinda reminds me on my young days ...
That spray welding is a process that if you hadn't known about it, and someone told you it would work, 99.9 % of people would say you're crazy, and laugh. Amazing how that flame keeps oxygen in the air from burning up the metal powder before it reaches the work piece. And how those particles can bind to the relatively cool metal shaft. It shows how the bond is at the atomic level, right at the surface. Like when steel cutting torch slag sticks to concrete. I've got some on my driveway that a pressure washer didn't dislodge. The camera work was outstanding.
I was hired on to a factory back in the early 1990's. They gave me the job because I was the only applicant who could spray weld. I ended up spending six years sitting on a chair spraying finger sized casting to harden them. When I took the job I was given a coffee can full of the clips to demonstrate my ability. I didn't know there was a warehouse full of 55 gallons drums of the exact same clips to be sprayed.
I am a Journeyman HVAC Tech. I don't know nothing about machining, but I find that I am glued to watching this. I've had some big blower wheels shafts get absolutely milled when a pillow block bearing goes bad. I didn't know you could do this kind of repair. Very cool.
As of today 803 thumbs down. I am amazed at how many people that are so gifted that they can be so critical of his effort to give useful information and entertainment. I just wish there was more accountability in these comments. KEEP UP THE GREAT WORK
Hey, no worries…thanks to Bye,Done! and his amazing popularity (/s); YT is no longer letting anyone know (publicly, at least) how many thumbs down a video has received! In other words, we deal with tanking political public approval by CENSORING!!! YAY! Cheers, and who cares about the haters? They’re not who you make the videos for anyway!
You did a very fine job on that shaft. The customer should be delighted to get that shaft back. It is good there are people around that can save that shaft in a professional manner. Much respect to you.
Thank you for showing and explaining this process to all. Found it fascinating and your skill is quite obvious, old school Craftsman methods are still alive today. Two thumbs up for sure!
Very nice, as a former auto-detailer I look for the final shine. then i know the true gift of an artist, as opposed to someone just filling the position. Sad thing is it took me three hundred video's to find this channel. Now I have 299 to watch to catch up. Thank you for your time and talent, most important your willingness to teach any willing to learn. Best wishes, and good health to you and yours.
You said it. The difference between skilled and competent is a canyon! Johnny Idiot can clamp a spot welder down and hit the trigger, but can he make it LOOK good after?
Very satisfying to watch that whole process. I've been a Tool & Die Maker/Repairman who has been welding and machining for nearly 40 years and I really enjoyed this video.
Great camera angles on the spray welding. The multiple angles really make for a professional looking video. A lot of people think making videos is easy. The editing for this multiple angles is a lot of work
Love seeing old techniques still being used in modern times. Time is money to everyone and spray welding done right will save a lot of time and bring in a lot of customers. Well done!
Nice shop you have there. I worked in a job shop with an old guy when I got out of trade school as a welder back in "81" for about three years. They were a dying breed back then, all the others opting to move to production work. That was one of the more enjoyable jobs I've had. That was so much fun learning to use all the machines in the shop and new projects to figure out and work on every day almost. The old guy was a master at it and a hoot to work with. I moved on and wound up in electronics which I've done for the past 30 years. But I'll always love and have a soft spot in my heart for machine shops. :) Great vid. Thanks for sharing!
I'm an attorney. I have never even been near a lathe. Had no idea of what "spray welding" was. I am in awe. What precision. I wish I had valuable knowledge and talent like this. This is what made the country great.
You've got skills! Getting a law degree is a big deal. I feel you though. I have a degree in mech engineering and often overlook how much work it took to get my stamp.
Between my time as: a Fabrication and Repair Machinist in the Army, Tool Maker Apprentice, External Crankshaft Grinder, Kearney & Trecker Milling and Grinding Machine Rebuilder Machinist, Deburring/Parts Finisher, Tool Room Machinist and Parts / Production Machinist I can run and do everything he can except Spay Weld. But I can also run CNC and older Automatic Screw Machines and Tape Operated Machines. It gets tough when you have to switch back and forth between old and new machines because of differences in the lines of code language used and the different codes as well. I can Mig, Tig and Heil-Arc weld, Silver Solder and Braze as well. I started running Sunnen Hones, Natco Multi-Spindle, Radial Arm and regular Drill Presses, Engine Lathes, Surface Grinders and Air Grinders part time back in 1969, while in HS. Shapers and all the other machines on and off until 2017. Good thing I'm retired or someone here would want me to fix something for them. This man is very good at what he does using old school machines. there is a lot more to do when using these things and many things come with experience and "touchy-feely" adjusting and correction skills learned.
I know almost nothing about machining but I really enjoy watching your videos reminds me of the reason our country is so great, we have talented people like you repairing rather than replacing things in what has become a throw away society. Thanks and congrats on your 300th. video.
I appreciate this man because he doesn't treat his knowledge like it's some secret that he must never share for fear of becoming obsolete. I was a maintenance technician for 28 years, and besides many hours of tech schools, my training was OJT. The techs who were most valuable to me were just like Abom79. They shared what what they knew to make me a better technician. They understood that more qualified people carrying the load made the job easier for everyone. They also knew that passing their knowledge to the next generation was the best legacy they could build for themselves.
The spray welding I remember as a kid, watching my grandfather and Dad, they called it "studite" (spelled wrong I'm sure) but they put it on plow shears and lawnmower blades to make them last longer..... Thanks for the flashback makes me miss my grandpa! They called him Flamin Raymond for a reason! Great video!
In the early 80's I worked for a company that repaired cast iron moulds for the glass bottle industly, we used spray welding to fill in the cracks & damage. Nice to see it again :0)
Great video. I really like how much care and attention you put into getting the item absolutely right. The final finish looks great and the tolerance and level of detail you go to. Its great to watch.
The scotch bright polish is a nice touch. I was a machinist at a phosphate mine for 40 years and did quite a bit of this type of work. Been retired now for 10 yrs.
I am 60 and a former A & P Mechanic and had never heard of this type of welding, this is one of the best videos I have ever watched and wish I had half of your skill.
same here never heard of spray well before but I've done a lot of different type of other welding this was the most awesome thing I've seen and very well explained throughout video step-by-step. I would have been afraid to take off the other end where point meats shaft. Steering shaft may get too hot and sag.
I do this quite often for centrifugal pump shafts. I’m glad i have found Adams channel about a year ago. This process is way faster than trying to hog out a complete shaft.
Wow, your camera girl is pretty good. Good framing. But the icing on the cake is those goggles. I expected to see Mad Max come charging in to get his goggles back! Seriously though. Some people like windchimes to soothe their weary mind... But I could watch this metalworking all day... It's just relaxing to watch a skilled tradesman work out a masterpiece.
Wonderful nostalgia. You are using the most primitive first generation flamespray torch that Eutectic started selling in the 1960's. The most unique thing about Eutectic was that, at one time, the Eutectician would train customers on the optimization and limitations of the maintenance and repair products and procedures they sold. You did an amazing job with limited information. Imagine that in a fraction of the time and using exothermic powder you end up with a coating that looks like solid stainless steel or chrome mirror finish without the grainy look and producing a nice curl when machined. Castolin/ Eutectic now sells a ninth generation torch . With the right training your torch can duplicate those results. I did it for 30 years. Nice job.
You are a great presenter! That's a great skill beyond the machining. One of the best TH-cam videos I've seen on any subject. Good job. I worked in factories where we occasionally had shafts spray welded but I never saw the whole process up close.
Glad to see Abby out in the shop. I'm retired from a naval shipyard and the flame spray process was used extensively to repair high end components.

Also the spray material has micro pockets that hold oil better
I doubt it was the cold process as shown here. The application you describe may have been a fusion process which looks similar to this.

As a dentist, I thought our profession did some precision work but this is just amazing! Love watching a craftsman. All the best from Scotland.

To see a true craftsman take this kind of pride in his work, makes him more than just a machinist, he's an artisan. This is a true art form in metal.
Thanks for taking the time to show the entire process.
When you stumble across this and really have no reason to check it out, but watching the precision work keeps you interested. Truly nice work!
Efficient, meticulous and properly reasoned. This is a man at the top of his trade.
Love that this type of repair is carried on by displaying it on TH-cam. Techniques like this used by industrial craftsmen of the past are being lost in today's service oriented throw away society.
To all who may read this comment: I've been working with machinists for 30+ years. Very few will use this process. Most will lathe the original work piece smaller and then add an additional piece of material/metal. Spray welding is an art. This video is the mark of a MASTER. 'nuff said.
Watching a craftsman take pride in his work is a great thing. Well done.
This guy is good. I would hire him any day. He does work as if it was his own.
Thank you for taking me back down memory lane. I sprayed thousands of parts back in the seventies. Started off at 18 as a sandblaster. Worked my way up to metalizing, thermospraying and then to plasma spraying. I enjoyed those years working in that machine shop.
There's a certain satisfaction you get in repairing something not many others can repair.
WELL DONE ABOMB 79
I dont understand why anyone would thumbs down this video I got nothing but complete and utterly satisfaction from this video...you dont see many good machinists anymore, oldschool skill is slowly fading away with today's technology.
Jared Simpson, I don't think they thumbs down due to video quality. My best guess is that they just don't want this type of content to show up in their recomendations? I agree with you that this was a great video. 👍
I can't speak to all your viewers, but speaking for myself, this is a hell of an interesting process and I'll never get tired of watching you spray weld.
I am a retired Machinist/ Toolmaker of 45 years and I must say you are doing one fine job. It’s nice to see some people still have what it takes, common sense, patience, and perseverance. Well done!
There’s a man who takes incredible pride in his work.
...a man **who can** take incredible pride in his work.
Litch anyone can take pride in their work. You just have to want to do it.
As an apprentice millwright, I find that many tradesman go the extra mile to do a good job. Settling for nothing but the best way.
Theres always a few hacks.
Just take pride and ownership in your job and it will pay off every time, regardless of the industry you're employed in.
@Igor Stephonivich Crash not in a capitalist world. it's nice that capitalism is losing supporters as generations come and go. soon we will have all working people taking pride in their jobs. Sadly, the way it is now, people's pride and values can be easily bought off in a world where money is everything.
@@Ryzot -
Capitalism is freedom to do your best, the better your product the more the reward. Some people like the state to take care of them and other people like to take care of themselves. You can not group all people as one kind, if you want to live in China, Cuba, North Korea, Venezuela, Finland, Germany, etc. go ahead but I'm staying right here, and loving it!
Not just fixed, it's cleaned up from top to bottom. Lots of pride in your work there and I admire that.

This is what YT is about for me. Not some silly ass influencers and their bullshit. I prefer watching content like that, with hardworking, skilled people at work!
You are a true craftsman. I’m an engineer and sometimes I feel like we get all the glory but it’s our manufacturing people that are truly amazing. God bless you sir
I am beyond impressed by your level of expertise and craftsmanship. Utterly fascinating seeing this hidden world. You are truly an awesome example as to why we should encourage young people to consider trade schools and the like.
Really nice job, it's good to see real tradesperson doing a proper job. I work in maintenance shop and it is very hard to find a good machinist. Keep up the good work!
I have to say that, if this one video is any indicator to me, you are a great machinist and an excellent teacher! You laid out all of the information in a logical way, took me step by step through the process, and showed me the end result. I have subscribed so that I can learn more.
What a treat watching a master at his craft - not just the spray welding but also the polishing, the measuring, the fine lathe work.
What a pleasure to see a professional tradesman at work. Good onya mate. Such a thorough and beautiful job. Fantastic dialogue too, really well explained. I remember seeing the machinists do this when I was an apprentice mechanic in the 1970's. It was Eutectic Castolin equipment too. They sprayed crankshaft journals where the bearings had spun. Quite amazing. How tough is that shielding paint!
It's nice watching someone who takes pride in their work and goes the extra mile. Good work!
Thanks to the
Very trye.. a craftsman who knows his trade backwards.
There is a certain joy I get from watching an expert at his work. It doesn't really matter what that is.
Working for Otis Elevator as a Service Manager in Richmond VA my repair crews would encounter a galled shaft on a worm gear shaft or other shaft. Due to maybe a failed bearing on very old elevator. Our vendor machine shops could spray weld the shaft then turn it beck to original diameter. This was in the mid to late 60’s . We had wonderful machine shop vendors who could fix just about anything made of steel or bronze. Great video .
Great to see this being done again, I used to teach spray welding back in the 1980s with kit much the same as yours.
I don't comment on many videos but I must say you have a great way of explaining and demonstrating your craft.
The world does not turn without guys like you .... nice work
Skilled craftsman doing fine work. The heart and soul of America.
Thank you for sharing with us. This is the kind of repairs Dad, Jack Karp, used to do for Commercial Fisherman in South Beach, OR. I hadn't seen this tool in many years. Reminded me of the 1980's, watching Dad do repairs for a good price, high quality & timely delivered to get them back to sea fishing. He could fix it better, quicker & cheaper. He liked his work to be perfect. I miss him.
Wow, this brings back some cool memories of when I worked as a machinist early 80s for a now defunct company, Beach Russ in Brooklyn, NY. We used to make vacuum pumps, smaller ones mostly for the food industry and the large ones for the US Navy. When the pumps would come back for rebuilds, I would repair the shafts in some of them using this very same method. Saved many shafts this way. I suppose, this technology was pretty innovative at the time. Amazing it is actually still being used. Great vid.
What I love about wasting time on TH-cam; you learn something you had no idea existed, and all of a sudden, you didn't waste any time, and you learned something that might come in handy someday!
Very good video! Back in the 1990s I had a 3" or 4" by about four foot long shaft repaired by spray weld, as far as I know it is still running 40 years later. It was a large blower fan (60 HP or larger) on an air handler, first we had some vibration, than it became a rumble and then we found the culprit. The worn shaft was spinning in the bearing.
A new shaft would have been a lot more cost than the repair was and we also replaced the bearings.
Awesome job dude, I never came across watching a lathe in action ever since way back when I was in high school metal shop class. But this is way more advanced..... you have given that worn down shaft another chance at value, and prob. saved the owner a lot of $$$..... You are a true Craftsman, thank you for sharing the value of your trade.
Thank you for taking time out editing and sharing your craft , and all your knowledge, it’s absolute gold . I’m not a machinist I’m a artist , but I appreciate the technical craft. And the precision is addicting .....
This is people’s livelihoods and it’s also craftsmanship of highest degree and it’s art to me
It has been years since seeing this done, outstanding job! Was stationed on a TENDER in Norfolk, Va. from 1970 to 1973 as a Machinery Repairman 2nd Class. Our shop had about every type and size of machine you could imagine, in late 1972 we started doing metal spray on pump shafts in an attempt to shorten the turn around time, had pretty good success with it. Great video! Will back for more.
Outstanding work have not seen this in the UK since the 70s , people have signed up for the throw away society now, decreasing number of skilled people like this. Thank you for video.
I'm 75 today and if i could live my life over again id learn everything i could in machine shop works and Spary Weilding, beautiful work this guy does.
I'm not a welder of any sort. I have no aspirations to be a welder or machinist. But I've just watched this entire video to see a master craftsman at work.
True! I'm and IT guy and I love this!! :DD (but until I was 12 I helped my uncle every day with machining & repairing agricultural machines and cars/trucks)... Kinda reminds me on my young days ...
If you'd like to hear a lot of really broad spectrum music mister click on my icon it's good stuff
That spray welding is a process that if you hadn't known about it, and someone told you it would work, 99.9 % of people would say you're crazy, and laugh. Amazing how that flame keeps oxygen in the air from burning up the metal powder before it reaches the work piece. And how those particles can bind to the relatively cool metal shaft. It shows how the bond is at the atomic level, right at the surface. Like when steel cutting torch slag sticks to concrete. I've got some on my driveway that a pressure washer didn't dislodge.
The camera work was outstanding.
I was hired on to a factory back in the early 1990's. They gave me the job because I was the only applicant who could spray weld. I ended up spending six years sitting on a chair spraying finger sized casting to harden them.
When I took the job I was given a coffee can full of the clips to demonstrate my ability. I didn't know there was a warehouse full of 55 gallons drums of the exact same clips to be sprayed.
what the hell is clips ?? just asking
I don't completely understand what I just watched, but I'm glad I found this channel.
Lol! I’m with you!
He putting metal back on that metal piece man
I am a Journeyman HVAC Tech. I don't know nothing about machining, but I find that I am glued to watching this. I've had some big blower wheels shafts get absolutely milled when a pillow block bearing goes bad. I didn't know you could do this kind of repair. Very cool.
Yep! If no one notices till too late they can cut almost all the way thru the shaft.
As of today 803 thumbs down. I am amazed at how many people that are so gifted that they can be so critical of his effort to give useful information and entertainment. I just wish there was more accountability in these comments. KEEP UP THE GREAT WORK
totally agree - I'm often amazed how many dissenters there are.
Nice job
Hey, no worries…thanks to Bye,Done! and his amazing popularity (/s); YT is no longer letting anyone know (publicly, at least) how many thumbs down a video has received! In other words, we deal with tanking political public approval by CENSORING!!! YAY! Cheers, and who cares about the haters? They’re not who you make the videos for anyway!
You did a very fine job on that shaft. The customer should be delighted to get that shaft back. It is good there are people around that can save that shaft in a professional manner. Much respect to you.
Thank you for showing and explaining this process to all. Found it fascinating and your skill is quite obvious, old school Craftsman methods are still alive today. Two thumbs up for sure!
Very nice, as a former auto-detailer I look for the final shine. then
i know the true gift of an artist, as opposed to someone just filling the position. Sad thing is it took me three hundred video's to find this channel. Now I have 299 to watch to catch up. Thank you for your time and talent, most important your willingness to teach any willing to learn. Best wishes, and good health to you and yours.
You said it. The difference between skilled and competent is a canyon! Johnny Idiot can clamp a spot welder down and hit the trigger, but can he make it LOOK good after?
Its quite humbling watching a person with so much skill and confidence. I throughly enjoyed watching this.
Very satisfying to watch that whole process. I've been a Tool & Die Maker/Repairman who has been welding and machining for nearly 40 years and I really enjoyed this video.
Nice use of PPE. You don't just teach what you intend, you teach everything you show.
Great camera angles on the spray welding. The multiple angles really make for a professional looking video. A lot of people think making videos is easy. The editing for this multiple angles is a lot of work
Love seeing old techniques still being used in modern times. Time is money to everyone and spray welding done right will save a lot of time and bring in a lot of customers. Well done!
Nice shop you have there. I worked in a job shop with an old guy when I got out of trade school as a welder back in "81" for about three years. They were a dying breed back then, all the others opting to move to production work. That was one of the more enjoyable jobs I've had. That was so much fun learning to use all the machines in the shop and new projects to figure out and work on every day almost. The old guy was a master at it and a hoot to work with.
I moved on and wound up in electronics which I've done for the past 30 years. But I'll always love and have a soft spot in my heart for machine shops. :)
Great vid. Thanks for sharing!
I'm an attorney. I have never even been near a lathe. Had no idea of what "spray welding" was. I am in awe. What precision. I wish I had valuable knowledge and talent like this. This is what made the country great.
You've got skills! Getting a law degree is a big deal. I feel you though. I have a degree in mech engineering and often overlook how much work it took to get my stamp.
Between my time as: a Fabrication and Repair Machinist in the Army, Tool Maker Apprentice, External Crankshaft Grinder, Kearney & Trecker Milling and Grinding Machine Rebuilder Machinist, Deburring/Parts Finisher, Tool Room Machinist and Parts / Production Machinist I can run and do everything he can except Spay Weld. But I can also run CNC and older Automatic Screw Machines and Tape Operated Machines. It gets tough when you have to switch back and forth between old and new machines because of differences in the lines of code language used and the different codes as well. I can Mig, Tig and Heil-Arc weld, Silver Solder and Braze as well. I started running Sunnen Hones, Natco Multi-Spindle, Radial Arm and regular Drill Presses, Engine Lathes, Surface Grinders and Air Grinders part time back in 1969, while in HS. Shapers and all the other machines on and off until 2017. Good thing I'm retired or someone here would want me to fix something for them. This man is very good at what he does using old school machines. there is a lot more to do when using these things and many things come with experience and "touchy-feely" adjusting and correction skills learned.
Randomly found this but was fascinated and loved every minute till the end. Thank you
300! Seen em all! Really enjoyed the explanation at the end. Thank you and God Bless.
I know almost nothing about machining but I really enjoy watching your videos reminds me of the reason our country is so great, we have talented people like you repairing rather than replacing things in what has become a throw away society. Thanks and congrats on your 300th. video.
That spray welding always looks amazing.
I appreciate this man because he doesn't treat his knowledge like it's some secret that he must never share for fear of becoming obsolete. I was a maintenance technician for 28 years, and besides many hours of tech schools, my training was OJT. The techs who were most valuable to me were just like Abom79. They shared what what they knew to make me a better technician. They understood that more qualified people carrying the load made the job easier for everyone. They also knew that passing their knowledge to the next generation was the best legacy they could build for themselves.
The spray welding I remember as a kid, watching my grandfather and Dad, they called it "studite" (spelled wrong I'm sure) but they put it on plow shears and lawnmower blades to make them last longer..... Thanks for the flashback makes me miss my grandpa! They called him Flamin Raymond for a reason! Great video!
In the early 80's I worked for a company that repaired cast iron moulds for the glass bottle industly, we used spray welding to fill in the cracks & damage. Nice to see it again :0)
I'm the medical field but I truly enjoyed watching your video. Nicely done and very professional. Talk about precision work !
Great video. I really like how much care and attention you put into getting the item absolutely right. The final finish looks great and the tolerance and level of detail you go to. Its great to watch.
Agreed. The whole process with the micrometer on the lathe was amazing.
I love seeing someone take pride in their work. Good job.
The scotch bright polish is a nice touch. I was a machinist at a phosphate mine for 40 years and did quite a bit of this type of work. Been retired now for 10 yrs.
Thought I would scan through it quickly , however I was quickly hooked, and ended up watching every minute. Fascinating. Thank you for sharing.
I am 60 and a former A & P Mechanic and had never heard of this type of welding, this is one of the best videos I have ever watched and wish I had half of your skill.
Yes same.. never heard of a spray weld befor..
same here never heard of spray well before but I've done a lot of different type of other welding this was the most awesome thing I've seen and very well explained throughout video step-by-step.
I would have been afraid to take off the other end where point meats shaft. Steering shaft may get too hot and sag.
Whoever invented spray welding was a mad genius.
I do this quite often for centrifugal pump shafts. I’m glad i have found Adams channel about a year ago. This process is way faster than trying to hog out a complete shaft.
Wow, your camera girl is pretty good. Good framing. But the icing on the cake is those goggles. I expected to see Mad Max come charging in to get his goggles back!
Seriously though. Some people like windchimes to soothe their weary mind... But I could watch this metalworking all day... It's just relaxing to watch a skilled tradesman work out a masterpiece.
Wonderful nostalgia. You are using the most primitive first generation flamespray torch that Eutectic started selling in the 1960's. The most unique thing about Eutectic was that, at one time, the Eutectician would train customers on the optimization and limitations of the maintenance and repair products and procedures they sold. You did an amazing job with limited information. Imagine that in a fraction of the time and using exothermic powder you end up with a coating that looks like solid stainless steel or chrome mirror finish without the grainy look and producing a nice curl when machined. Castolin/ Eutectic now sells a ninth generation torch . With the right training your torch can duplicate those results. I did it for 30 years. Nice job.
Adam you are one hell of craftsman i truly enjoy to watch and learn from, Keep the good work up, and keep them coming 👍👍👍
You are a great presenter! That's a great skill beyond the machining. One of the best TH-cam videos I've seen on any subject. Good job.
I worked in factories where we occasionally had shafts spray welded but I never saw the whole process up close.
