100 Year Old Broken Gear Brazed Back Together
ฝัง
- เผยแพร่เมื่อ 9 มิ.ย. 2023
- I received a couple of parts that were badly broken that come off a Silver Manufacturing Co. post drill press that is 100+ years old. The gear and feed arm were broken during shipping and will need to be brazed back together. In this video we'll work on the gear. I use a combination of fixturing and clamps to hold all of the parts together for brazing. For the brazing filler rods I am using my Eutectic Xuper 146 XFC premium brazing rods. These are high quality rods that will provide good strength for the life of these parts. Because of the amount of work needed for these parts this will be a multi part video series on the repair. #abom79 #brazing #industrialrepair #gear #vintagetools #oldtools #postdrill

I’ve not seen brazing filmed this clearly before. I could clearly see the interaction between the flame and the rod. This should be a standard for technical schools.
*Trading schools
@@kramler If you really want to get picky about wording, "technical schools" is better than your suggestion because presumably a "trading school" would train someone selling stocks. The "technical schools" were, once upon a time when some of us were young, called "vocational/ technical schools" and included a significant amount of skilled trade coursework. Metal shop taught machining and welding. Wood shop taught some framing carpentry, some finish carpentry, and fine woodworking. Portions of the time were carved out for the students to get academic credit and actual on-the-job training in their chosen trade. Some no longer teach the skilled trades, but many still do.
Did you miss the parts where he says he screws up. Or his monologue in part two where he blames out of practice, been years, oh the hub may not be centered. Did you even watch before commenting?
@@jerrylondon2388 perhaps we have different views on education? I think showing things where someone eases up and admits it. That can give someone more confidence to admit their own mistakes.
@philipallard8026 Then you will love part 3 where he doubles down and screws it up even more. Then finally asks the owner what kind of repair they want, wallhanger or useful? Then proceeds to do his usual "good enough" repair in a rush to get it out of his shop! "World class" I had to put that in there for the fanboys.
Adam, nice weld job. Nothing against your new shop, but I always like watching you work in the old shop. Must be the older equipment and the way the shop is set up. I like old stuff....
Quincy, Massachusetts
In 1962 just out of high school I worked at a farm machinery repair shop in Wrens, Ga. My first job at the shop was to make long brazing rod out of short ones.
I remember learning to braze with Oxy-acetylene in the 6th grade,... in the 70's when things were cool and kids could be curious! ( a small hammer that I still have in my tool box.)... It is so sad that kids do not have shop classes these days in school. I developed a love for tools and craftsman skills in my 6th and 7th grade shop classes.. Woodshop and metal shop... We cast belt buckles, spot welded, bent steel and used machinery for candle holders, and in woodshop made family signs for our houses and learned the tools and the methods of building from wood..... I have all my items from shop class... They are very cherished items... I hope one day kids can once again learn to manufacture and build... It is a skill very much lacking in our kids education!!
I too went to shop in high school in the 70's. In the 80's the education system got into "social engineering" along with liberal political movement and one of the first things that got sacrificed on this "alter" was the technical shops.
Adam, I'm a licenced forklift driver (although it's not how I put food on the table at the moment) and I always operate on the principle of "how I would I like to receive this if I'd ordered it for myself?" and behave accordingly, I work in a supermarket doing the home delivery but sometimes I also do shopping and I use the same idea, "would I buy this for myself?" it doesn't take much effort, physical or mental, to do things properly, some people are just lazy.
My father used to work with safes and they were always coming in damaged and having to be returned, because fork jockeys and truck drivers see a safe and think "oh it's metal, it'll be fine" or "it's metal, it's heavy and doesn't need to be secured as much as the manufacturer specifies" not realising that a lot of the time the skin is relatively thin and the interior material, which provides the fire resistance, breaks from shocks and big impacts which compromises that aspect of it, making the safe worthless and unable to be sold.
My dad was a certified welder with a degree from Ferris. He told me the torch never stops moving in brazing, and your to use a near elliptical pattern across the weld to draw the braze into the joint by moving the heat across it. With this method i have never failed to braze anything properly, still use his old torch set.
Adam, Abbey is not only a beautiful woman but an excellent camera lady too, well done both of you. Joe.
The close-up camera work is just incredible! Many thanks for bringing us in close, from all of us who will likely never experience this firsthand!
Wow. Abby sure got some great close-ups of that brazing. Some of the best I've seen. Many thanks to both of you!!!
Great camera work Abby !!!
Yes , that was AWESOME
Thanks Abby !
The best close ups of brazing cast iron I've ever seen. Assuming Abby gets the credit there :) I like your new shop, but always feels like coming home when you're here.
Nothing beats a bit of Abom79 after a long day at work! keep up the great work!
I've used the techniques and processes you've demonstrated on your channel to sucessfully repair several damaged or broken castings. Thank you for taking the time to demonstrate and share your knowledge.
I also enjoy you taking the time to share your desire to expand your knowledge and experience in your new shop, despite those that may not be as into it as the rest, even to the point of being rude. Again, thank you for shairing on YT.
I can remember the early SNS days when you were planning that side extension, now you have another shop and over half a million subs.
What a journey.
Adam, this is the best brazing job I have seen you do. When Abby grabbed the camera she followed the torch so closely. It was like "Blazing Saddles" and "Ring of Fire all at once"!
Did you count how many times he admitted on camera he screwed up? And yet you're fanboying "the best brazing job!"
Step 1! Dye Penetrant Testing. Determine the scope of your work! It could have a dozen cracks you cannot see. It's not a child's jigsaw puzzle. It is a brittle metal that was dropped. He still needs to test for crack before proceeding. "It's cracking!" No, it was already cracked. You didn't do your prep work! Not professional. Clearly, he did line work, the same thing, all day, every day. Your general skills never improve, except that one single skill is great. Brazing, is not that skill. Nor was job planning. That is why he can't learn CNC, it requires job planning and problem solving in detail.
You haven't seen much brazing, then
I'm not a religious man but as far as I'm concerned that is gods work😊 so good to see the prep work, attention to detail and professionalism.
AMAZING! You sir are a master at your craft. I went to university of Miami with a scholarship but working with my hands was what I really enjoyed, so I left the university, tried other jobs and became an electrician, so for 45 years that's what I did and never looked back. Best decision of my life. Was never happier. Once you find yor niche in life it gets easier.
Best video brazing I have ever seen. I am not even a welding/brazing apprentice, but I love learning something I have no clue about. Most videos are just a bright 2" blinding light. This was good. Thanks.
No blinding light because it was brazing, not welding.
I usually set my torch lower when brazing with bronze so that bronze only melts on the nail pattern of flame at the tip of your torch, that helps me keeping the torch at a same closer distance (not moving back and forth) without melting anything else than the bronze rod. I'm sure your method works fine too, but it's what I learn from my dad who is great at brazing with bronze. Thanks a lot for your awesome content!
3:10 You're right the cog and pawl are part of the downfeed. As you crank the handle to rotate the drill there's a cam that engages the pawl's arm and it advances the downfeed screw a couple notches to put pressure on the drillbit.
It works sort of like the table crossfeed on your shaper.
What I find interesting is it kind of hammers the bit down into the work one chip at a time rather than a continuous feed. I think this would probably give advantage when drilling steel with crappy carbon steel drills of the time, encourages a less than capable bit to dig in and make chips rather than rub and burn.
Keep up the great work, we appreciate you.
I just inherited my father's shop full of tools, some of which I have no idea how to use. Watching you has taught me a great deal. I look forward to learning more about how to use some of his equipment, some of which I remember from my single digit childhood. Thank you for your clear, easy to follow descriptions of what you're doing.
You need some Cleco Clamps for that. Originally developed for the aircraft industry. They are used across many industries now. There are many different formats of the Cleco clamps from hole type to hold sheetmetal aligned for assembly or jaw style clamps. I have collected a large supply of these and found they to extremely useful in all types of situations. Always amazed at the quality of brazing you can accomplish. Thanks for sharing.
P.S. Glad to see you back in the original shop. You seem more comfortable here.
Nice to see you back in your old shop.
I like the old shop!
I love the look of brazing. It's like that japanese art of repairing ceramics with gold.
Great job filming the brazing process!
A very difficult job done with great skill and excellent camera work by Abby. My hats off to Adam for brazing those cracks successfully from both sides without the filler falling out.
It's still cracked! He didn't test for cracks. It was a mediocre job, and we haven't seen part 2 yet! Fanboying doesn't make it better!
Same way my dad taught me to fix cast. Also enjoyed the video from the home shop for a change. Thanks
Love the camera work up close... First time I've ever seen brazing. Looks a lot like soldering, which I've done a lot of, just a LOT hotter.
Brazing IS very high temperature soldering. While quite hot, the base metal is not melted. In welding, the base metal is melted. The bronze alloys used in brazing are comparable in strength to cast iron, BUT the difference in cost between ferrous material (low) and cupric material (high) is SUBSTANTIAL.
I would highly suggest looking at Instapack bags for these expensive parts. You do the mix procedure, put them in the area/box your trying to protect. Will save you a great deal of time packing, and when you choose the right densities, its hard to get wrong.
Never seen anything like this before. Fascinating. Brilliant camera work. Thanks for sharing.
Love the new shop, but really good to see the home shop.
My Dad worked as a blacksmith when he was young. This upload brought back memories as his brazing was absolutely beautiful. I loved watching him weld/braze.......he couldn't see why I was so intrigued.
I've watched you for a long time Adam, but that's off the scale control and pure talent.
I love Brazing! At work one time many years ago the shipping guys knocked a Toledo scale off the counter shattering the cast iron cover on the base! The scale still worked fine but the boss asked if I could fix it. Must have been 20 or so pieces. Now fit them all back together. I got it done but it took a while!
And @1:54 Forklift "Squirrels" really piss me off! They go running around full throttle like it's some kind of game instead of a job! I have two certs, regular and all-terrain, and I did NOT EVER try to rush the machine! My job was as an Engineer so I had to be certified for everything we used, from Bobcats to small Cranes! Just to move around the parts for things we were building! 😆😆
Great job, and super camera work. Was that Abby? Such a difficult thing to film with such huge differences in brightness. Cuts of this would make a great tutorial video with an explaining voiceover.
I believe that is well done enough to qualify as Art.
Exquisite camera work watching Adam tip toe along the brazing work , great focus and colour temperature , probably among the best camera work I have appreciated on this excellent channel!
Absolutely I was going to comment but you beat me to it.
Awesome! Love the old shop stuff. I miss the big projects you used to do at Motion. Been following you for a long time.
Always love to see cast iron repairs. Different jobs & different people call for different methods, but just the reputation it’s got for being tricky to repair always gets me interested.
It’s another one of those jobs I’d love to get into, but just don’t have the time, not since I started rebuilding vintage magnetos & other old vehicle electrical components.
Looks like machining is problem-solving. The more skills, knowledge, and experience you have the more problems can be solved. Thanks Abby for the killer filming!
Absolutely, the worst that I've ever had to deal with was a maritime satellite antenna assembly that got forked. It was on a beautiful skid and boxed with 1/2 or maybe 3/4 plywood. But at some point in shipment or storage at our site. There was a fork blade punched through the box that left a gouge in the gel coat and glass mat. We got a decent repair of the dome using a repair kit from West Marine, and with the dome in place, you can't see the repair. Honestly, after it was repaired I had trouble seeing the repair from 4'.
Brazing is a skill set on its own. Great work Adam.
What a great video. Loved watching you working to control the puddle, loved the camera work that allowed me to watch you working the puddle. Most excellent team work.
Gas welding is how I lerned to weld as a teen , way before Mig or Tig , nice repair .
I'll be honest, brazing is usually about as fun to watch as watching paint dry, but the way you filmed this was fantastic. It was cool to see the braze flow in the joint, and definitely made it more interesting to watch. Keep serving up different perspectives on everything you do! I look forward to every Saturday when a new video drops!
Thanks Adam. Great Video. We appreciate your hard work on these.
Fantastic brazing tutorial. Thank you, Adam!
Great close-up footage of the brazing! Thank You!
That thing was smashed, literally, into pieces!!! Amazing brazing job, man. Much respect from Texas.
Great work, as always. It's nice to see your decisions on the best way to make a repair come to fruition. And I always love seeing the picture, at the end, of what I assume is you, your father and your grandfather; so great to see a family business handed down. Thank you again for the work recording, editing and publishing your videos!
Absolutly fascinating video. I'm no metalworker, but I'm constantly repairing stuff and your method of dealing with complex shapes is super helpful.
Love seeing the old shop again…..
a perfect example of the fact that no one ever had too many tools. experience and understanding what is needed good work. looks like you are having fun life.
GREAT WORK ! .. BOTH OF YOU ! .. THANKS
Abby killing it with the camera today!! 👏👏👍👍
Might want to put him in touch with Clarke over at Windy Hill and see if he can get another one cast, bc I have a feeling as old as it is that more cracks are going to develop, not on where you brazed but in other sections just bc of its age. 👍👍
you mean in touch with Karen and Kurtis at CUTTING EDGE ENGINEERING AUSTRALIA...the best
@@SalvoMorina CEE doesn't do casting though?
@@dolvaran you are right, but CEE produce the best video in machining community ever...
@@SalvoMorina Can't argue with that. Karen is excellent.
If you have hundreds of thousands of dollars of new CNC equipment, why would you cast a replacement part. Even after a successful casting, you still have to machine the new unit. You need to spend hours or days designing and making a model to create a mold. Even then it may fail spectacularly.
Somewhere Rucker is smiling! XO
Outstanding camera work! Great job Adam.
am farmer so repair stuff all the time. this vid really helpful. thanks
The camera work was just as good as the repair.
Great clip and excellent commentary, makes it understandable to anyone
Looks good,Adam.Hampty Dumpty sat on a wall,Hampty Dumpty had a great fall and Adam put it together again.Thank you.
Stunning camera work! Thanks!
That breaks my heart, excelent repair!
Same tool shipped to me ( post Drill ) with a broken Arm. Fixed it but I hate Brazing cast Iron. Great Job.
Nice seeing the old shop in action again.
You're the man Adam, nice work
Looking good and strong Adam, be great when its all done and cleaned up.
Congratulation adam, im very happy to see your old style videos ❤
Nice repair, Adam. Always learn something watching you!
As alway it's good to see you do your great and qualty work lear alot from you Thank you
You did an awesome job on this repair and an excellent video! The camera work really captured every step of your process. Well done, Sir!
Beautiful work Adam
As Justin over on the Fab Series keeps chanting, your mantra in TIG is "time is temperature", so holding the arc just a fraction too long will melt the base, which is what makes TIG brazing so hard. A TIG arc is also up to 11000 F whereas an oxyacetylene flame is anywhere from 1500F up to 5700F depending on your gas setting, so the heat transfer can really fly with TIG.. I personally find TIG welding and TIG brazing to be very different feeling processes even though they are both done on the same kit.. In TIG brazing you really have to be modulating your foot control carefully and paying attention to where you're pointing that tungsten to not overheat, whereas in welding, if you overheat the pool a bit, the weld looks a bit uglier there, but no real consequences, and it's very different feeling vs just briefly pulling the flame away to solidify the filler and regain control of the procedure in gas brazing. I personally would have MIG brazed the part having had lots of success with that process with various broken castings..
A tricky brazing job, making sure the gear still runs true with respect to the spindle bore. Great job, enjoyed watching your process.
I wonder how well the hub is aligned with the gear after the repair - the newly formed crack was awfully wide. I'd probably clamp the wheel upside down so it registers on the gear teeth to make sure the setup is in plane, and indicated the whole thing on the mill for concentricity.
Fork lift drivers take pride in their work too- I was often chosen for ticklish, expensive work. You don't get good work for minimum wage. But if you saw how some folks pack their stuff...
fantastic camera work!!!
Adam, the great closeup camera work (Abby) on your brazing should even aid you, perfecting your own skill as you watch this video playback!
Spectacular brazing images. Controlled chaos.
A real craftsman. Nice job as always.😎
Very cool fix.
Nice camera work!
Instant foam packaging is the absolute best invention for shipping irregular shapes and delicate items. I send instrumentation and pump equipment across the country and overseas with zero issues.
Great craftsmanship! As always 🙂
Always enjoy watching your videos. Nice work, nice shot, nice equipment and nice videography. Keep em coming! Much love
Awesome job, Adam :)
Thanks for sharing.
Darn good job Adam! You are a pretty talented machinist! It is always a pleasure to watch a man do a good job. Your customer will be highly pleased with the end result. REMEMBER, box it up right when returning it to your customer! 🙂
Amazing job.
Great job Adam.
thanks for another fine Saturday. night well done.
Hey Adam, your use of the TIG welding equipment begs the question, why don't you fusion weld cast iron repairs with nickel filler.. I have been doing TIG/Nirod cast restoration work for many years. A TIG/NiRod repair gives a good color match for restoration work and i've had 0 failures Just a thought, thanks for the great content
He says in the beginning that he thinks his chosen brazing method works better than TIG with nickel rod. Might make a neat video to demonstrate why
I guess he prefers to work a way he knows than experimenting with customer part
Hi Adam. I have done a lot of oxy acetalene welding in my time. Well done , great job.
Regards.
Steve.
I like it when you 'brazenly'repair castings(sorry for silly pun,LOL) these types of videos are my favorite!
Good day noble Adam. Excellent repair work. Oxyacetylene Oxygen is still a wonderful repair weapon for all welds.
I have some extremely fine oxy-fuel torches in my arsenal. Also try a Dillon MK3 / Henrob Torch. It takes a little getting used to in handling, but it is a very special device. With such a burner you can save a lot of gas / oxygen. He has a very soft flame etc.
I also weld lamellar (lamellar graphite) cast iron mainly with Castolin / Eutectic / Eutalloy welding consumables. It is one of the best welding consumables with the longest & best experience in metallurgy.
I always have very good experiences with welding additives of the same kind, for example = Castolin 14 or with = UTP 5 in hot welding. They are of the same species - cast iron welding rods in 4.00 mm or 5.00 mm.
This is then no longer brazing, but welding.
I really like your old workshop. That's how I've been working for over 42 years.
Warm regards from Lake Constance / Switzerland
:walter
Love the presentation and content. You Sir a master of metal! Fantastic film work, great....Just great (I think this was a great balance with CNC content as well.). Appreciate you both, stay safe!
The internal stresses will make this repair crack on its own. The entire part must be raised to the red temp.
Of all the welding/ brazing types, I think I like torch brazing best. The satisfaction when it flows is special.
I have figured a way to watch your videos while confined getting a pacemaker.
EDIT: Around 40:00 - Very nice fill.
I've had to heart valve replacements welcome to the zipper club I'm 40 still working 14 hrs a day it gets better brother
@@Kevin-qo6jw - Outside of the interminable periods of fasting before various tests and procedures, boredom was the worst part of the experience. They eventually installed the ICD (implantable cardioverter-defibrillator - gentle "pokes" to keep my heart at the right speed and a "zap" if my heart goes nuts) and sent me home on the sixth day.
