Nice build and great re-cycle of the broken rivet tool. As for your brazing skills, I can only repeat the tipps/comments of some other fellows: you're starting brazing by far to early. Your burner has certainly enough temperature/power for the job (at least for such small parts), BUT you need to get the part to brazing temp first and only then start fluxing and melting the brazing rod. For steels a good indication for having reached brazing temp. is usually when the part starts to be of cherry red colour.
If you start earlier, you only burn the flux and with that the flux is not working anymore at all. Then you get a so called "cold braze" with internal pollution of burned flux which consequently weakens your braze joint.
thankyou its my first time and im learning thank you for the tips
ALLAAHU AKBAR.
SALAM DARI JAKARTA INDONESIA.
hamdo lilah
very very nice,tank you ostad
marhaba you are welcome
Good Design!
thank you new and improved one is coming soon
Don't use the torch flame to melt the filler rod, use the heat of the part. That avoids the filler just sitting on top in a ball. When you flux, wait for it to actually bite before adding filler.
So, ignore the outer flame (yellowish cone), and use the inner blue "flower" to heat the part. When the part goes dull red, flux. Keep the filler rod in the yellow cone to build heat in it, but not melt. Work the "blue flower" over the joint until its bright red, and the flux has wet out, and floated off the oxides and crud (black stuff floating on top of the puddle of flux). Now put the filler into the "blue flower", touching the joint. If everything is hot enough, you should only have to do a quick dab, and the filler will melt and flow out a bit. Pull the filler rod away (back into the yellow cone so it stays hot) and use the blue flower to add heat where you want the flowing liquid filler to travel. Repeat the heat, dab, flow steps until your joint is to your liking.
thank you so much for taking the time to give all the details i'm still learning and i'll keep what you said in mind when i start i thought i just have to melt the road on the joint and that's it :) thank you
@diycreativecrafts4461 a pleasure. It just takes a little practice, and knowing the steps to do it. When you see the filler sitting in a ball on top of the joint, you're working too cold. If your flux dries out and turns into a black crust, it's too hot or you waited too long. When both parts are bright red to orange, it's good heat to add filler. The filler rod cools the parts when you dab, so quick dab and then keep the blue flower on the joint, favoring where you want the filler to flow to. The filler wants to flow toward the heat. You can also "push" the filler with the force of the flame, so if the parts are hot but the filler isn't quite flowing fully into the joint, you can adjust the flame angle so the heat in the part pulls the puddle and the flame blast pushes it too. Just practice, you'll be brazing like a pro quick.
@@ludditeneaderthal thank you you ar the best all the tips are awsome im making new torch i cant wait to put all the ifo to practice thank alot
@@ludditeneaderthal thank you im making new torch i cant wait to try all the tips you provided you are the best
@diycreativecrafts4461 it's a pleasure man, glad you're learning the skill. Once you like your brazing, move on to gas welding. They're 2 skills you'll use your whole life
You gotta get that flame much closer, you're not heating the metal enough to braze. Aim for the "flower" of the flame, not the tips of the longer flame. Itll heat a lot quicker
thank you so much i will practice it my first time i thought of adding compressed air to get more heat
Isme koun sa salding ho sakta h
Get some powdered Borax to use for flux.
i had a flux but i dont know if its the right one
Merci❤❤😊
