I too tried with sand and failed exactly as you said. Then I used solder to melt (and solidifies) inside the aluminium tube, and it worked. The backing plate part is very useful. Great vid. Thanks for the upload and good work. Love from Indonesia.
Congratulations! You are a very gifted fabricator. I enjoyed watching your video. You demonstrate and communicate your artisan skills in a relaxed, clear manner.
Thanks for sharing this hard earned knowledge, really very helpful. I hoped to see more of your videos..I hope you post something before long. can you please tell me what grade Aluminium you used and if you annealed it? thanks
Allsome video very interesting, i like custom parts anf modified parts content! Can you show us some more of you tricks of the trade, snd how you build bikes and things?👍🏻
Cool method. I think I've seen videos where they've used sand but welded the ends shut before bending. You'd imagine the same process would work with a liquid as liquids can't be compressed. Maybe even have a valve on the end where pressure can be added if the tube stretches.
Awesome technique. Would recommend exploring a material without cadmium because of the health and environmental concerns. I'm a long way from green peace, but the juice isn't worth the squeeze. I'm not willing to risk cancer for a nice bend.
Great video, what grade of aluminium are you using? also, does the low melting point alloy leave a residue inside the tube after you melt it out? I'd be worried it would contaminate the material for welding
Can you please repeat the name of the material you use to fill the tube before bending? Fantastic video, BTW. It is hard to find real informative content straight forward like you did here.
Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a pentavalent post-transition metal. Melting point Bismuth 271.5 °C Melting point Aluminum is 620-650 °C
You could make a end flange for the tube that strap to the end openings ,or weld end plates on the tube and add an air valve...then compress the tube with air and then do your bend ...just need a compressor and a way to hold air in your tube....you could figure out how to make custom end plates to save time...then you would just hook up the air hose and then go bending...or 3d print it then dip it in ceramics (lost pla) and then cast it in aluminum that is another very easy solution when working with aluminum...........your welcome.

Brillant!!
Really enjoyed this look forward to try this technic!
Bloody Clever Mate. Top Job, thinking outside the box. Excellent video. Cheers from Michael. Australia.

I just learned more in 8:16 than I thought I ever would.
All very clever , Hat off to you sir
Thank you very much for sharing ,and love your work . Brilliant !
badass!
Brilliant! Thanks!

Dang, he called it Horror Freight in public before I did. I've been calling it that for years.

Super smart!!
Thank you so much.

Legend. Excellent work sir period even enjoyed the music and your commentary:-)

I have never seen this before! Thanks!
Wow thanks for the knowledge drop!
Thanks
Do you have any trouble getting all the bismuth out before you weld it? Wondering if it leaves a residue that needs to be sanded out?
Any process for making sure the bending alloy is completely removed and doesn't contaminate the weld or boil off when welding?
Im wondering if filling the tube with plaster of Paris, or even a block of plywood would also help?
I'm one of your subscribers
Does all the bismuth come out of the tube will it contaminate welds?
the bismuth all comes out, it sits on the aluminum like oil on water, so as long as you get the tube warm enough, it all rolls right out
From Philippines?

search woods metal
the second i saw the steel plate i knew what you were doing haha
We're real proud of ya
Can I have one piece of metal tube squar u use
Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a pentavalent post-transition metal.
Melting point Bismuth 271.5 °C
Melting point Aluminum is 620-650 °C
the metal he is using actually called "woods metal" has a melting point of 70C. Its an alloy made out of bismuth lead tin and cadmium
Can you make me a die set for 3” square tube?
HORROR frieght??
Sir
What the name of the metal
aluminium
Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a pentavalent post-transition metal and one of the
Because in our country we
Don't have that kind of metal
