This video describes my technique for braze welding (silver solder) broken bandsaw blades. It includes description of a jig for grinding a chamfer on each end of the broken blade, a jig for holding the blade for welding, applying silver solder to the joint, the welding process, grinding the weld smooth and annealing the blade after the weld.

Carl- finally broke a quality expensive blade. Went to a major welding school and they could not help stating it required a special jig. At a large welding shop they stated they wished there were a way to repair their blades. Your talent is very much appreciated! Now installing retractable casters on my heavy table saw with information from another of your videos. Thank you so much to share your knowledge. Best of all I have my 10 year old grandson with me for the summer and am trying to instill these 'fix it' habits that are lost in our disposable society.
You remind me of my uncle. He was a wise man who spent a lot of time in his wood shop. He had no problem letting me watch and he took the time to explain. Just wanted to say thanks for taking me back to a time that meant a lot to me.
Not only do I really enjoy these videos, but it is a reminder how our shops can be made and not bought
Watched other videos about this topic. You have added a number of useful tips and info. Cut the solder and place between the joint. Anneal the metal. And you make folding the blades look so simple. I would probably cut my nose off LOL.
I'm just getting to the point in my woodworking journey that I felt compelled to find a fix for broken band saw blades. This is the first RUclips video that I watched on the subject, and it will be my last. Carl, the way you provided references in the beginning, and your way of creating this video has given me a complete understanding and confidence. Thank you Sir.
In today’s instant on-line information on everything. With all written material outdated. I also have a large collection of magazines and books. I have learned the value of an author getting information published. Today anyone can publish anything. No experience required. No fact checking no proof of accuracy. As a master craftsman like this gentleman can spot bad information. This is why published information is so much better. After it is published in a magazine. The readers Peer review the information and a good magazine will publish good and bad comments. With the online experts the only comments are what the author allows. So no negativity.
Young craftsman are often misled. That is why I maintain a library that I can refer to along with my written notes.
Thank You for sharing and including the references. This is a sign of a REAL craftsman.
I like your blade-folding technique better than the “flip-and-twist” I’ve seen elsewhere. Thank you.
You have such useful, practical and often ingenious videos; I have no idea why you don't have 10 times the number of subscribers. Some time ago I watched a video from The New Yankee Workshop that showed a retractable-caster assembly-table. One of your videos was recommend by RUclips afterwards. You are in great company for a good reason. Thank you so much for sharing your knowledge with the world.
Carl, thank you for sharing this video with us. Your presentation style is a joy to behold. I admire your conscientiousness in crediting your sources.
Love the jigs so muck simpler than others i have seen.
Great video Carl! Love your resources and your integrity passing down where the information originated....love your characture, videos, and ingenuity. Thank you for sharing.
Carl, you're a trucker on the Information Super-Highway, just delivering loads of useful stuff. ;)
Great presentation Sir! I loved the tip at the end for turning the giant loop of the completed blade into a much smaller, tri-loop!
Great video, chief, thanks again for posting this, very inspiring !
Keep on trucking ! (from France)
What a nice old Gentleman! Thank you so much, Sir! Thanks to your good-humoured and very informative video presenting some really great tips now, on the other side of the globe I can finally fit some good quality and cut to size blades on my peculiar German made band-saw. Well done! Regards form Bulgaria
Great demonstration Carl, thank you. Every video of yours I've watched is useful or inspirational. You have an amazing mind good sir.
Thanks Carl I really liked that jig for the disc sander
Great video. Loved how you folded the blades at the end
Thanks for the excellent content. You make that look easy.
Awesome simple video in both explanation and execution.
Thank you so much, a wonderfully clear video and a charming gentleman to boot!
Very informative. I'm looking at buying my first band saw and doing all the research I can.
Thanks for this video, Carl. I just broke two blades on my new bandsaw. Now that I know what not to do (too much tension), I can try my hand at soldering them back together.
Great video. Some very useful information! Thanks
Great Video Carl.
Thank for "twist the top" simple for a good job !
I doubted whether I would dare to start the job, but after watching this video, it seems a lot less complicated. Thanks !!
Most excellent video! Thanks a lot!
Hi, Carl
Excellent job !
I do it the same way !
Fritz, Germany
Well done, Carl.
Very nice work keep up the good work we need you...
Thanks for that great tip Carl!
wonderful tutorial! Thanks!
Great job. Thank you for making the video.
Interesting to see you using regular solder paste for silver brazing. I did 10 blades today with hard silver.. should be good for years now. I sharpen them too.
Thank you for posting this! It's going to save me a lot of $
Great video. Thanks for sharing your knowledge. 👍
Thanks Carl. Great video.
It really worked! Built the alignment jig and the grinding jig and fixed my first blade. I bought enough solder to last 5 life times LOL. But even that was about what 1 good blade costs. Thank you for you video! JohnB
Awesome as always!
Thank you for the video ,greatly appreciated
Nice informative video, Thank you.
Hello Carl,
Many thanks to you for sharing and taking the time to make this video, it was just the information I was looking for as My band saw has just spat out another broken blade.. As I am a refrigeration Engineer, I was already thinking I have pretty much have all the tools I need to silver solder the blade, I just wondered if it was indeed practical and was also wondering how to build a jig to hold the blade in place...
You just answered both my questions.. and guess What I shall be doing tomorrow ?
Oh.. BTW...
the ideas about chamfering and annealing the blades had not yet cured to me until i watched your video..so that was also very us-full..
great video..
Nicely done sir. I can do that now. Thank you.
Nicely done
Thanks for the tip Carl.
Thanks Carl, I actually have that issue of FW magazine! Little did I know! OK, off to repair some blades, Thanks for sharing
Fantastic informative video.
I would love to see a video were you tell us about yourself. For example about your hobbies and your working experiences.
Thank you for your informative videos.
That was great , I love the disc sander jig too but the best is how cool you loop fold your blades.. had me laughing ...I do mine outside, about 5 mins each and plenty of jumping out of the way . I'm going to practice that technique and one day be as cool as you Carl ... perhaps .
I made a copy of your scarf joint jig, thank you very informative
Very beautiful work...Good
Great Job! thank you for sharing
Thank you for such a smashing video, i thought it would be much harder to do :-D
Super helpful, thank you for sharing!
Thanks Carl . Good video.
BELLO BELLO BELLO! Bravissimo....
Nice fix.. thanks for the info..
Good one, Great way to save some money. Thanks for sharing!!
Hello Carl, thanks for this very clear demo. I would like to try this as I have quite a stack of broken blades. Can you reference the type of solder you are using, I find the world of solder and fluxes a bit bemusing as there are so many for welding, , bfrazing and soldering. Best wishes . Peter
Thanks for the clip some useful tips.
This is very informative
Svaka cast matori! Pozdrav iz Srbije
Хвала вам; greetings to Serbia from Canada. ////Carl

Спасибо Дедушка,но Вы опоздали,нас такому научили лет-так 25-ть назад электросваркой!
shouldn’t you use brass for brazing rather than silver?
Thanks Carl, I had never welded by blades. What a waist of money.
ممنون و سپاسگزارم استاد نازنین عالی کامل آموزنده بود . با احترام.🍕🌷☘🌷🌷🌷🌷🌷🌷🌷🌷🌷👏👏👏👏👏👏👏👍👍👍👍👍👍👌👌👌👌👌❤💛💚💙💜
What bandsaw is that and are you running that 3/4" blade on a twelve inch machine? Discuss please?
Great Video. I'm out to my shop to make a jig and try my first repair. Thanks
me too
Hi from Sweden nice and easy to follow your instruction by the way are you Swedish
Would this method work with a 38 foot bandsaw blade with a 15 guage steel that runs at a high speed in a sawmill? I'm told that they don't like to put welds in them because it makes them brittle so when our blade snaps we throw it away. The problem is that right now steel is so hard to get our company that makes our bandsaws is really struggling trying to find it. Thanks for your help.
I have no experience or training on sawmill bandsaws. I couldn't hazard a guess as to whether it would work. ////carl
Hello there, if you have a lot of problems with broken band saws, maybe they are simply to thick. Use a thinner blade and the problem can be solved. Also the sharpening techniques can be the
cause.
Thanks for this great information. How long do the silver soldered blades last? Do they fail at the soldered joint when they eventually fail?
Good quality (Swedish steel) blades usually last till they need resharpening; cheap blades may only last a few hours. Yes, they usually fail near the weld, ///carl
Great awosome Job 👍🏻 👍🏻 LG Sam
I’ve made dozens of blades this way and never had one break at the joint…
Carl, your garage is really un-American. Can't even imagine being able to park a vehicle in a garage. . . Thanks for sharing!
Thank you.
Hi Carl. Where do you get your silver solder? I know very little of silver soldering properties or various types of silver solder. Could you Please help me come up to speed with the stuff? Thanks (in advanced).
E-bay sells a lot of it. It's REALLY pricey.
What percentage of silver strip do you use, where do you get it,
B.P. www.leevalley.com/us/wood/page.aspx?p=41049&cat=1,41036,41048. This is a refill kit, solder and flux, for their bandsaw blade splicing kit. Unsure of silver content. ////Carl
Thanks Carl another great and helpful video.
Good idea, for those tiny saws, but being 45 yrs in the business of welding saws we call this silver soldering where silver solder melts at 1125 degrees , not welding, big difference
are u using flux?
what type to use . i tried 5 times and failed all attempts . i have hard silver wire 75% silver i cant even get it to melt .sigh , i have 3 blades to repair lol . not sure what im doing wrong . maybe my torch isnt hot enough ,
A.C. Thank you for looking at my video and thanks for the question.
I use flux generously. I buy bandsaw blade solder and flux kits from Lee Valley tools. Their flux dries up and solidifies before I use it up so I've been using muriatic acid paste flux with good success. The Lee Valley silver solder is in strips 0.005" thick, 1/4" wide several inches long. I cut off about 1/8" for narrow blades, 3/16" for wider blades and slide the piece of silver solder between the chamfered and overlapped ends of the blade. It only takes about 10 seconds of heat with an LP torch to thoroughly melt the solder and have it flow over the whole joint. Maybe 15 seconds for 1/2" or 5/8" blades. Remember, the tip of the flame is the hottest. If I was using round wire silver solder, I'd hammer it into a flat thin strip. Keep trying; we've all had to learn from our failures. //Carl
