Round Pipe Bending Mistake // Round Pipe Bending Tricks How to prevent thin stainless steel pipe from being compressed metal and steel pipe wrinkle problem solve #mdkhan #diy #welding
Great idea ! I worked in a metal forming shop, we used a special metal called "KIRK SITE", it is like Aluminum, except it melts at 165. degrees Fahrenheit, we would heat it then pour it into tube or pipe then make the bends. Mostly in STAINLESS STEEL, then heat the piece and the KIRK-SITE would run out and the piece would be smooth without defects. Great Video. Greetings from Los Angeles. California 🇺🇸
Thank you for this: This was amazing to me, so I did some research - : Kirksite melts at 395°C (745°F), it looks incredibly useful - The stuff you were using appears as though it could have been Cerro Bend which melts at just 70°C (158°F) ?
первая труба была с тонкой стенкой ) а у второй стенка толще) и согнуть ее без вмятин проще ) засыпь песок в первую трубу и посмотрим на результат)))))))))))
First tube was thin wall aluminum. Second tube was thicker wall stainless. (You can tell by the color of the weld) I call BS using sand without capping the ends TIGHT.
Cambie la curvadora, trabaje con una bien diseñada y nunca deformo un tubo sin añadir arena .en produccion en masa no puedes estar perdiendo tiempo en taponar con trapos apretar la arena etc. Osea mala la maquina ademas esta mui lejos el punto de apollo, y pierdes tiempo en amordasar el tubo .lo digo con 5 años de experiencia trabajando con curvadoras curvadoras
The pipe which came out with fine bended is thicker than the previous one which was very thin but the guy did not show the thickness of the pipe but for first pipe he showed that it was thin
You need to fill sand to be successful, that is because your technology is not good, so how much time will be wasted. You don’t need to fill sand, just change the shape of the mold groove and you can bend successfully.
First you must wear the shirt for two to 12 months straight, this will allow your bodies natural body odour to linger and survive long after you remove it for washing[your body not the shirt] remember you didn't wear it months straight to wash out those built up grease stains, next find a third world country so dirty no one notices your stench or filth, once you have gained access and blended in with natives you begin to whiten you clothes[note the joke of using plural of cloth as we all know that one shirt is it] now the whitening begins, role in lots of dusty environments usually asbestos is good as impregnates your rags you will become more or less fire proof, then the final stage is to literally burn all that grease and fat out of the clothes as you enjoy the once a year bath in the nearest river/sewer and bingo fire proof clean rags which no one dares steals as the stench is your own unique flavour. Enjoy.

I don't understand how that worked. When I use sand I have to crimp the end of the tube off or it'll simply push the sand out of the way. This is for things like a brake line or gasoline line and making those tight corners.
Apparently you missed the part where he tamped the sand down after plugging the ends with rags. It does work. I have also filled them with water and froze them.
@@donmunro144 I didn't miss that part. It doesn't work. I tamped it down with as much pressure as I can put on a 1/4" pipe full of sand. Even using a #5 hammer to drive a rod into it. I tried it dry, wet, it didn't matter. It simply pushed it out when I bent it. Rags won't hold it and I'm fairly sure they didn't freeze it given where they are and the equipment they're using. Maybe it's different with a big relatively thin pipe vs a small pipe. Even with a crimped end it still has to be a very good crimp or it'll push that out as well. That is, I can't simply smash it together with a hammer for example. I have to fold it over. That's why I'm asking here. I'm trying to find someone that has done it without crimping it. I have a lot more brake line to make soon and that pipe is expensive. I'd love to know how GM, Ford, Toyota, etc do it in the factory. I know it's done by machine. However, they still have to worry about it kinking. Maybe they can get away with heating it. The pipe I can buy has an external coating that is very good. However, I don't think it can take the heat needed to bend it.
@Robert Thomas when I'm doing brakelines i use a pliers style bender for 3/16 & 1/4 in line. Then I have a die and shoe bender for up to 3/8 line. Anything bigger i normally fill the line with water and freeze it. Then bend it.
@@robertthomas5906 ... I do brake lines all the time, and yeah, I do occasionally kink one. The key to NOT kinking is holding pressure so the line stays in the groove of the bending tool. Depending on where the bend needs to be, sometimes it's better to put your bender in a vice so you have two hands to keep the work in the right place. In recent years I have switched to the coper / nickel variety line. So much easier to work with. BTW, I concentrate on the actual bends and if they don't line up quite right you can twist the tubing for a better fit. That's where the new stuff shines. Hint: remove the old line, place in on the bench, then use that for your template. If the line is more that 3-4 ft long make it in two pieces and add a union where it's easy to reach. (thinking about those GM lines along the frame rail) I usually do from the rear to the middle, and from the front to the middle, then do the union where they meet. (where you have room to work)
The radius of the bend should be at least 6x the diameter of your tubing to prevent kinks. I do brake lines and fuel lines all the time using a beer bottle. It gets you a variety of radius to choose from at the bottom of the bottle and along the tapered neck. Move the bottle along the tubing as you bend so you are bending a little in each spot. Use 1 hand on each side of the bottle holding the tubing with your 2 thumbs pushing on the bottle. No need for sand or special tools. Dont put sand in brake lines anyway
