- I made this small white metal arched gate for the front of a clients house. It was very simple but fit the style of what they had going on.

I see this radius issue all the time doing circular graphic designs. The inner most radius will have a tighter circumference as the outer radius will be larger in diameter. They're online calculators that can help you figure out the exact math. Stack 2 of the same coins ontop of each other and slide one below the other, the radius will not match. Hope this helps.
^ said it better then I could 😂
This is exactly the problem!
:) I think at one point in time we all ran into that-- I learned it to understand a bit different : take a big washer, cut it in half and place them on top of each other, than slide one of them -- tataaa -- now the problem is at least visible. its not solved, but at least my brain stoped passing out :)
Yup...just look at a washer...big circle and small circle - they track equally the whole way around.
I see this as a reason to purchase a bender to do at home.
Great job
another work of ART!!!!!
The inner radius must be smaller than the outer radius if the center point of the circle is the same. In this case you needed to have the inner radius 5 inches smaller than the outer radius. Whoever did the bending should have known that.
This is correct.
Appreciate your honesty always, most people make things seem easy but I’m sure it took many trial and error to learn and master the craft
If you put heat into just the inner part of the circle ...cool and repeat in sections...you'll get your tighter radius without any tugging. When you put heat into the outer edge, you were fighting yourself.
Looks awesome! Love your channel!
Can a gate be gorgeous? It's gorgeous and cute too!
Concentric circles have different radius always. Otherwise they lay on top of one another.
2 different radius! You got it. If it went on the bottom... the same distance from the center, it would have matched. Needed to be a tighter radius which is exactly what you did.
Love your videos!
Whether the top radius or the bottom one is your target radius, it's calculated from a fixed point on the center line so the difference in separation is the difference in radii. Say that the inner edge radius of the bottom piece is 12 ft, the inner edge radius of the top piece would need to be 12 ft 5-1/4 in. The same holds true if you were to make an arch from some kind of sheet or plywood. The difference would be the width of the arch you are making.
Hope this helps.
There's a trick to bend the tubing a little more with the torch. You have to heat up only the inside of the radius red hot, then immediately quench it with the hose. Repeat it for each of the sections that you did it on, and you would've been super close on the first try.
I agree, it can be used for bending and straightening.
@brent8922 Yes, it works every time for me. There's a bit of an art to it, but I use it when the material pulls on me.
Yes, as the comment two below says, concentric circles have different radii. Turned out great though... nice work as usual.. cheers
Post radius is genius. Great work
Beautiful gate! And King Metals has a great spokesperson!!!
Working with curves is always a treat! Good work.
Sweet
Very nice job.
For a visual of the problem. Try stacking two exact round discs on top of each other. Then slide one down about a 1\4 of the way. You will see the same problem you have. Thats because the diameter of the disks is the same and you are moving the center of the circle down. To have an equal gap from the top you need a smaller circle and not move the center of the circle down. Think of a dime on top of a quarter with the same center, and a quater on top of another quarter sliding one down with out the centers matching.
But anyways, like always a great job!!!!
Well said and good example. The reason this probably hasn't come up before is the "smallness" of the gate. With lower dimensions this difference get exaggerated quickly.
Im a welder based in Ireland and would never use a angle grinder with out a guard. Great video
Good looking gate 👏 every job is a learning process, of your learning your doing good. 🇺🇸💪
Both arks have to be , in the inside of the sides ,you have the top on the outside . After that you cut the tip and add some metal .
Difference in radius is inside and outside
Jimbo is the man
Beautiful gate. That must be very satisfying doing such fine work. Thanks for sharing
Absolutely beatiful.
Looks great!
Looks awesome great work as always 👍👍👍
Nice work as usual Jim!
hi Jim regarding the Radis if the second one is 5 inches away just imagine a circle that's 5 inches smaller that will be the right one if your drawing it you basically offset the second circle by 5 inches
Great video and you sorted out that curve in the end. Whatever radius you ask the metal supply store for for the outer curve you just need to subtract 6 inches (or whatever the spacing you had between them was) for the inner curve.
Draw two circles with same diameter moved against each other in line - they will form kinda moon crescent instead of a parallel object. Good job tho!

The inner and the outer diameter of the curve ain´t the same if you do it another time remember to order the outer diameter at one piece at the same diameter at the other inner diameter. kind regards Erik I enjoy to watch you work I live in Denmark
Jimbo, when you were heating that radius piece with the torch you could see it moving back towards being straight, so when you would bend it, you were pretty much bending it right back to where it was before you heated it.
Take a pair of dividers and draw an arc. Now close the gap on the dividers and use the same center point and draw a smaller arc. The arcs will both have a different radius but they will be concentric to each other.

Difference between this two lines is the difference in radius of inner and outer lines of the square tube. Which is as You said 1.5”. Imagine that you try to match two different radius’s
If you don’t mind me asking how much does something like this run a customer?
Try a thicker gauge, like 14G it won’t deform as much when you roll it
You need to calculate the smaller radius and then multiply it by 3.14 to create the smaller circunsference.
If you are building a curved panel yes you want both radius the same. But if you are building a gate where the arch will be under the top you need to roll a tighter radius for the bottom you want it to fit nice under the top arch not staked on top
Beautiful gate... Just not fond of the white. Great job Jimbo !
Olá, eu também sou serralheiro e estou dando só a minha opinião, uma vez que o segundo tubo fica por dentro do aro o raio não pode ser o mesmo porque a medida interior é menor
Same radius circles will always overlap
Where do you go to get the bends done? I need to find a spot in L.A./O.C. area. Thanks.
I was told there’d be no math. 😂😬
What table is that Where did you get it
How much this gate ?
In order to stack arcs and maintain equidistance the inner arcs must be smaller radius. Think of a bullseye target. This is a classic mathematical error. While we think, oh its just the same radius over the other, when in fact the right way to think about it is just a smaller circle inside a larger circle so the inner circle must have a smaller radius to maintain equidistance.
Nice !!
Brilliant explanation. I never thought of it that way.
Very nice work, shame about the colour. Chrome or black paint would look much better
That isn’t stitch welding.
Beautiful job! Geometry is a bitch, huh?
The difference is the material thickness, so your inner piece radius needs to be the inside radius of the outer piece, basically it needs to sit back to belly else it wont fit, in future remember they need to spoon else you will have this issue again
Making this comment in the middle of the video, I don't know how it's going to end... but concurrent circles aren't the same radius!! What's the matter with your education system, i thought it was decent, say 20-30 years ago.
