How to bend square tubing without a bender - metal fabrication

706 ratings | 101951 views
I made this video to show you how to bend square tubing without a bender. You can bend small or large bends this way. You will need a welder, chop saw and math. I ended up making a gate with a couple bends and this is why i ended up using this method. I didnt have a bender…. But i did have my skills, and now they are yours! I hope that helps. See you later internet. Start over the math portion here: 04:50 SONGS: the urban symphonia, bubble walk. Both can be found on the youtube audio library

I love it. Practical math. One edit. At 10:43 where you say you need to add a cut, going from 10 to 11. That's not true. You still want to remove 1.25" = 10 x 0.125 (blade width) of material. But those 10 cuts will divide the length of tube into 11 sections, so to determine the spacing of the 10 cuts you divide the length of the tube by 11. Now that I got that sorted out it's time to fire up the chop saw and welder and bend some tube. Thanks.

How can you measure the ANGLE without computer or auto cad?
TRY to HELP you (5 months ago)
Yep, I said "cut". I meant, and also showed, divide by 11 which gets you 10 cuts overall. Thanks for catching that!

Pretty cool man - cheatyness is pretty much how everything is made! Cheaty? Yes, cheaty! You didn't make an arc, you made a segment of a polygon - but, nobody cares and it works so, cheaty. And good cheaty at that!
Brother man, excellent job. Im currently working on my gate and i am going the same route with the bend on top. Thanks for the video

Nice but I feel does cuts is adding a lot of extra work having to weld it and then grind it flush

If you know of another way without a bender please share. There are multiple ways to get the same thing done and without specific tools.

Excellent use of practical math. That being said, by the time I was done actually doing the math, I’d be done with the project through trial & error...or I’d just buy a bender instead of kerfing.

Your "wysiwyg" didn't work out. On the computer, the wood was cut at the same radius as the tubing.

once it's welded I think it is just as or stronger than straight

An easier way to find the length of steel needed for the arch is to measure the length of the gate and add the hight of the arch, done. If using a roller bender add extra length for the ends of the steel that doesn't get bent. And judging by all the time, effort and money spent on cutting, welding and grinding - it would have been easier to make your own roller bender which will also give you better results.

It's called kerfing . I use this method when make curved fronts on decks, or a window box. When I use this in fabricating, I always tack the middle first to hold it. Great video.

anlumo1 (5 months ago)
Doesn't really matter whether you're using imperial or metric here… if you just treat it as centimeters, it will work just the same, it'll just be much smaller.

Yes, yes... A way. We shall bend with the best of em.
If i have a piece of square steel that is 50 inch and the door is 35 inch the witdh of my blade is 1/8 is it possible to calculate 50-35=15 inch so 1/8*60 cuts 15 inch to get the proper length will the hight be the same 50-35=15 inch tall at the peak?

After Einstein and Bruce Wayne, you're next in terms of intellect and practical application of Geometry. Having been told by 5 metal fabricators that bending of Square tube needs a hydraulic. Press, die, gears etc., Your neat trick helped me get a gentle bend representative of a flower stem. Thanks for posting your video without which it would not have been possible!!! Will send you the pics when the structure is complete :)
purple6932 (7 months ago)
@TRY to HELP you ... let me know your email, i will send them there. I have recieved very good response from the client because i completed the job in under 3 days tops. Your technique was the key in saving time to get a curve in the 40mm GI tube. I shall post the photos on our webite https://arachne.co.in/ later, but you deserve the first look!!!

Awesome! I am gonna use this to cut my curved frame tubing for my new teardrop trailer. It is a french curve but once I figured out that all I had to do is change the distance between the cuts for the thing to work out, it was pretty easy. I made a test cut out of wood to see if I goofed, but I got it first time! I will do some minor tweaks though - it is nice to make test pieces. I am going to cut the metal next week when it gets here.

ok how about a 76 inch half circle out of 2x2 square tubbing how much far apart would i cut the tubbing with a chop saw to bend a half cirle 76 inches across . it would be 76inches half circle .how far apart would i cut the slots.

v8trauma (9 months ago)
Using imperial measurements as you do: Cut it twice as many times (21), then put a 1/16" shim in before you tack it up. Gives a smoother bend, pull the shim out before the final welds and you'll also get more penetration.

My wife and I are doing a school bus conversion with a roof raise. I have been looking for a bending tool to create a curve at the front and rear of the roof to give the bus a more retro look. Essentially an old Crown bus is what we are working towards. This technique looks like it will solve our problem of bending the tubing without spending a grand to buy a bender capable of doing what we need. Thanks for this video and the excellent explanation of what is needed to make the cuts to get the bend we want.
