great video,it is always better to repair then to spend money , i usually buy “broken” tools and fix them , now i learned how to fix bandsaw blades i will try it thank you
This little band saw has turned out to be the best tool purchase I've ever made ruclips.net/user/postUgkx5ZrqmYO2uJq_nuU8TopyWxVzn8vqmPUL Once doing the set-up as per the included suggestions, this table top tool has been my go-to saw ever since (8 months as of this review). There are few things I wouldn't attempt with this saw. It takes up much less space than my table saw yet delivers twice as much punch. I've used it to create slices of wood no thicker than an 1/16th of inch by using the POWERTEC BS900RF Rip Fence. For small shop projects this tool can't be beat.
Great stuff. Thanks.
Genial video...y qué buenos esos planos detalle!!!
Good Job.
muy buen tip
gracias
Gracias por enseñarnos como arreglarlas. Es un garron tener que esperar para poder seguir trabajando. Estoy mirando aqui en Argentina si consigo el alambre, que entiendo que es una aleacion de estaño plata y cobre. Gracias!
should there be a chamfer on each side of the break?
Muy vuen video pero que soldadura usa
Nice tip for saving money, I hope I never have to repair one but now I know.
Haha, you need the machine first, or do you have it😋
I need one :-)
What materials you put on blade before flaming please tel me
Mármol granito puede ser de piedra pulidas todo material en piedras y granitos
I am a machine repair RUclipsr in Korea. I'm going after watching the video.
I use a dremel diamond bit to sharpen mine. It works great.
What kind of soldering wire did you use?
nice one. my bandsaw blade just cracked and i plan to repair it. what soldering material did you use to weld it?
Silver
Long time thinking to repair that blades, if you are in the same situation, go and fix them
The teeth around the solder are ruined and weak now due to the high heat removing the temper, be careful not to put to much stress or cut anything with to high a hardness.
If your blades are snapping instead of popping out from too much feed pressure your over tightening the blade. Back off a little. That partially split blade you tried to repair that ended up breaking during the fix is really telling for that problem.
Some time later this video I found that the problem were some bearings in the machine that were blocked, once I replaced them, no more breackings.
What type of solder is used
It is silver, but it breaks again really fast
Hello,
How much have this torch °c/f ?
The silver melts at 962 ° C, the density is 10.49 g / cm3, but is the Worthington cylinder ts3000kc have so much °c?
I don't know the exact temperature, but I use a low temp. Silver solder, and that helps a lot
Que varilla utilizas para soldar ya que no he podido darme cuenta si lo dijiste, muchas gracia Alberto
Plata
Great video. I am about to purchase a vintage bandsaw and this will be very helpful in the future. I'm looking forward to watching your other videos.
Nice job mate , gonna av a go myself ,the blades are too expensive to throw away . i had a metal cutting saw a radial one, and it just kept breaking them i set all tensions right i didn't force it ,so at £16 quid a blade i got rid and got an old donkey say from the 50s it has 1 big thick blade and had it for ages . anyway its my woodwork bandsaw blade now thats broke accidently when woods twisted and ive thrown them but not any more im gonna av a go at this ,how long did they last ? Greetings from Wales UK .
They dont last long, I stopped doing as they breack again
Not sure if you mentioned or not but is that silver solder? Sorry if i missed it.
It is
Itu kawat apa, sebagai bahan soldernya
Que es mejor plata o bronce?
I've never heard of just putting solder! People always say to grind the ends to an angle, that's what I've always done. It's a little tedious, and the silver is as strong as mild steel anyway. They don't usually break. You do have to file the joint smooth.

Hallo ! Does this type of welds last for a while or do they break just as fast ?
It breaks again but normally let's me cut few more things. I use it when I don't have extra blades
@@edupuertasfruns i guess it breaks right at the welding spot. thanks for the reply !
Long time thanks...
I Love Ur videos, they help me a lot! Im working on a new Project right now, i want to make a figure with realistic muskle behavior. But i just cant figure out How to do it... i had an idea for the biceps an triceps how to make them flex if u move the vor-and-upperarm togeter the biceps would get bigger and if u straighten the arm the triceps would be showing! But im running into alot of Problems. Could u please try to make Ur own Version in a vid! That would be so helpful!
Wow, that seems so complex to solve, I will think about it but that is not something normal I have seen in stop motion.
Como se llama el polvo que echaste y se puede calentar con gas butano
Es flux y el combustible no importa sino la temperatura alcanzada
Hola no hablo inglés pero entiendo bastante de lo que dices amigo, creo saber por qué se rompen o agrietan las cintas a mí me estaba sucediendo lo mismo y lo pude solucionar quitando la cinta después de cada trabajo ya que si se queda montada en la máquina se estrellan cuando se enfrían después de cada trabajo
Pongo subtitulos en los videos en español. Yo he visto que normalmente se me rompen si no limpio el interior de la máquina muy a menudo. El pico de romper cintas fue porque tenia algunos rodamientos rotos y esto las rompia
Una vez estubieron rompiendo las cintas muy rapido y note que no tenia el hule que lleva y lo cambie y quedo listo

Crack
Wow, i thought that the soldering would break immediately because it's not flexible enough. But it seems like I'm wrong.
It works, would be better to supperpose the blades in 45deg, more surface to solder, but my machine has not much tolerance
He does say welding at least once.
To flip/reverse the blade you can use a corner of a table or anything like that. Hard to write out tho

I can fix your machine if its cracking again and again your blade and also teach you how to guaranteed un breakable joint will weld because I'm woodcutter here in pakistan faced too much machines with same problem and also fixed lucky know from my dad.
Wouldn't it be more ideal to just tig weld it? I'd imagine welding is stronger than fusing it with solder
Welds are brittle unless they are annealed afterwards.
I tried but its supertricky becausa the blade is super thin
This old tony make a video about this, and how to prevent a break in the weld
I've seen it much better than mine, I am a true big fan of his vids and jokes
edu puertas me too : D
edu puertas you know the frank howarth channel?

You're not addressing the real issues here. Stress cracks are caused by blade tension issues, band saw blades are welded with Flash butt welding. Blades need to be heated to 650 C for 30 seconds to anneal and return flexibility to the weld.
no material is added to a bandsaw weld. this will last for 2-3 cuts tops.
In my machine it was because a bearing but I did not know then. The welding worked for some more cuts while you get a new one, but I agree is not definive.
provato più volte, non regge si rompe di nuovo
Silver solder - 80/20 ?
Low melting point silver solder 55%
I did it too. This is what I used Woodglut designs for
Is this safe? 🙄
Going careful
Like si también odias ver sufrir al pobre :&.
You're trying to weld something in the wrong way
I will appreciate advice then
Thank you it’s very interesting although, in my case, the price of silver solder is much higher than new blades! Can I use something different? Anyone tried stick welding?
Silver solder is expensive but you only need a tiny amounts to solder a blade .. I cut of a piece about 6mm long and place it with flux over the joint .. its better to angle the joint to give a bigger soldered area .. its called a scarf joint and there are plenty examples on Google on how to prepare the blade before sondering
Yho😢4b
.ji ..😅
change the brand of blades wtf is that
