Segment Elbow Bend 90 Degree

hello and welcome back in another sheet metal  workshop video in this video i'm going to show   you how to make a 90 degree elbow just like this  one and it's got a radius you got a diameter   and it got segments so everything will be  explained during the video have a seat and   enjoy okay well let's get started now before  we start we have to know some information   and well that information if you have  measured or you get some information about   the pipe we're working in with there's an the end  list that will appear now in the screen so you   can see now that the endless there are all sizes  in in inches in the end you can see the radius   and you can see also the real pipe dimension  in millimeters so i have decided for a dn for the dn80 so i'm gonna write it on dna  it's got a five dimension of 89 millimeter it's a three inch pipe and it's got a radius of 114 millimeter and okay well that's that's all the information  we have and the pipe i'm going to insulate scott   also well that's something random i'm just going  to take 50 millimeter 50 millimeter in silation that means i'm gonna round off some sizes so if i  have a 89 millimeter pipe i'm gonna round it off   on 90 millimeter and if my radius is 114 14 i'm  gonna round it off my radius is going to be 120   radius and the pipe insulation is  50 millimeter so that means plus 100   we have a diameter of 190 with a radius  of 120 and it's going to be a three part bend so that is the information i have so i'm just going to show again the list in the  screen you can make a screenshot of that list so   if you don't have any idea or any clue how to get  those radius or dimensions it's a standard list   of course there are also other pipes with other  radius but that's uh something you have to figure   out by yourself once you have learned how to make  the segment bend then after it it's also easier to   take sizes and find out the radius  you need okay now let's get started now first what we do is make here a working line and now so we said we have here 190 diameter we have  a radius of 120 that means we go from the side   from the zero point here 120 millimeter and diameter 190 that means 95 is half so now we're going to make here a half circle i'm going to check it here so  we have exactly 190 diameter now we're going to follow up in the middle line  up you're gonna divide this part in two and now you're gonna divide here this part in three  equals parts or in six six equal parts one two three five six so we have here one two three four  five six parts divided with a bow divider   and for the next thing now we're gonna need an  angle because the band is 90 degree and we have   a three part band that means we need an angle  of 30 degree now if you have a a degree ruler   that means a degree rule i'm gonna then it's  easy because you just put it here on 30 degrees and that's 30 degree this is my zero point here then i'm put here my zero point and  then you can just pull a line for example that is my angle but we  are not finished so we're gonna do it   the way i've learned it in  school so you just take a radius you can take this one doesn't matter which one  you take because it doesn't affect the angle   so i'm just gonna take a radius well say from here you can also take the radius from from here or  a smaller radius i just don't take it from here   so those lines go do not cross each other  so you have a better look on what i'm doing   now if i divide this one you see here this one should exactly cross the line see this  exactly fits so this is exactly a tree part and if   i divide this one here and it's the same dividing  system as here only now i'm dividing a quarter   that means this angle this angle is 30 degree plus  30 60 degree plus 30 we have 90 degree so that   means if you have more segments you justified this  in the part segments you need you can also take   the circumference and define it the circumference  in the parts you want and then measure it up with a with a ruler like this and then take  that size so if you have five parts six parts   you just take the circumference  size and make that line now once you have divided like i have in three  parts i need now a half segment that means i'm   gonna divide this one again so that means if you  have three part segments i'm gonna divide it in   three parts and then i'm gonna divide it again in  half and that's the way i'm going to show you how   to do that so i'm going to go in on this point  and i'm just going to pull up here in a line   and here also from my working line one  so now i have here my point that means i'm gonna pull a line from the zero  point here where it all started through this point so now we have the exact angle we need for  our uh model we make the template we make here   so next thing what we're going to do is we're  going to pull up those lines so this here one going to pull up and the next one [Music]   so these are now my points so i'm gonna number  it number one number two number three number four   five six and number seven  so these are my points here now what we also were going to give here under so  this is here this distance is here 20 millimeter   and i'm going give swage  allowance 5 millimeter that means i'll give you 15 and now i have here down on the line so these are exactly my points including  the swage allowance the swage allowance   allowance doesn't affect the angle so if  you forget the swage allowance to give or   you give a little bit less or more it won't affect  the angle it will just affect the radius so the   radius is getting a little bit smaller or a little  bit bigger that's everything now this is now done   for now i hope you have understand everything if  not you can always ask me in the comments so the   next thing is what we're going to do is we have a  diameter of 190 that makes a circumference of 597 millimeter plus 30 millimeter overlap that makes 600 27 millimeter i need a metal of 67 27 millimeter  now i have here already prepared and metal and so i'm going to check this here out see and  put it here exactly on the metal where it is   and here you see we have here so we put here this exactly on the size  and here we come to 700 627 millimeter   see okay now what we do is we go left and right 15 millimeter and here also 15. [Music] and well i have here you see so the the  outside the biggest size from the outside is well   it's almost 65 so that means i need a maximum wide  metal of 130 140 so this is bigger i have here 180   yeah so you can always check here the biggest size   how big your metal should be so 180 i have  so i'm gonna put in here the middle line that's the middle line now of course i can make here this line a little bit more visible so and we're going to divide it in 12 equal parts so  i'm gonna make this also a little bit more visible yeah that's the thing if you  work with real sheet metal   it's always a little bit hard to make everything  looks visible because of the light and everything   so now as always we're going to use this  method to divide so i'm just going to hold my my measure tool here 650 i have here [Music] in  diagonal and a half of 650 is 325 wait a minute but you can  also put normal diagonals but just a diana diagonal also a method here if this smaller see exactly the middle so this is exactly the middle check this out so here touches and it touches here  see exactly the middle okay now next thing is we're going to divide  these parts exactly in 12 equal parts so putting this here on the line see here   the mill on the line and i'm going to  find something i can divide exactly in six   so six thirty maybe not thirty yeah okay  thirty yeah three hundred millimeter exactly in six parts so we have here   5 10 15 [Music] 20 25 and we do  the same thing on the other side and there's always a number you  can divide in equal parts 5 10. so once we do that again all of those lines now once we have everything ready the  next thing is we're going to number it   so well this is the the back and this is  the the the biggest size and that's the   smaller size so we when you look here that the  band here we have here the bigger size and we   have here the smaller size and exactly in the  middle where the seam is that is number four   so we start with the seam number four  and then we go backwards number three   two one and then number two three and you  see number four is in the middle and then   we go number five number six number seven that's  the biggest one and then we go back number six   five and number four so now we just what we have  is left is to drag over those points so number one here's number one number two number three number four number five six and the last one number seven i mean normally i i do not do that with a with an  adding it's always better to use this one   scratch needle you have exactly better sizes  but this is for the video i use this one   so now what we're going to do is we're  going to just connect those lines   so number three four and five should  be always will be in one straight line then we go from number five  four and five also straight line now we're going to make this rounding form  you can take a metal put it in a just like   this here i put and then pull up the line  but i have also something like this you see   it's it's a it's a rubber with something  like a metal in it and it's a good thing for   things like this so i'm just gonna put it here  on number one number two and number three see right i'm just gonna hit it once okay now we have a straight line and now number three two so now it's already in form okay well that's it so the next  thing what i'm gonna do is i'm gonna mark here the holes so just  gonna mark here the holes take my hole puncher and i'm also gonna punch the middle one so once you punch out the middle one you can also here cut this out okay now now i'm gonna just cut out my segment  and i'm gonna cut out sigma by hand because it's   always better to cut out by hand with your snips  so i'm gonna speed up this part in the video okay well once you have cut out the segment   your template is done so anything what is missing  is the information on it so always if you finish   if you finish a template always write  down immediately the information so we   have here a diameter of 190 and we have  a radius of 120 and it's a three-part   segment 3t dry tile so that's how we call it  in german so that's it now we're going to make   the band so you can always  check here this is a half   those two segments are actually almost like a  half segment and this is half segments let's   check out after if you cut it out if  there is any difference between see it's cut actually good so now i'm gonna make here [Music]   the band [Music] so now i have here you see it's already cut on the  exact size so i want to have a starting segment so so if this is my band so i'm  going to make it with an angle   this is my band and so normally it's round  but this is my bend and i want to have a size here of say 200 and here  i want to have a size of 180 that means if the radius is the radius is 120  that means its radius 120 200 minus 120 is 80.   so that means i give 8 plus 80 radius  plus 80. same thing here i have here 180   minus 120 so 60 is over that means and n segment  is radius plus 60 that is what we're going to do   so radius 120 starting segment is 200 so we're  going to do plus 80 that means 80 millimeters and if you if you give a swage so if  this segment is connecting another pipe   of course you have to give also  a little bit five millimeter   swage allowance you have to give but i'm  not gonna give here any swages so and now   here that is why we have cut out here this  middle part line we're going to put exactly here this on the middle line  same thing on the other side also so now we have exactly in the position  and now i'm just gonna draw here nice segment i'm coming here just to drag over those holes and now you just put it here on this line and if you have cut it out  good see it's almost equal drag over the holes so foreign and the last one now the last one is just put it on the line here and we're gonna only mark  the holes and here this line we're just gonna   make here the marking same thing on the other  side here also just make the hole and we mark   so that is the starting segment and that's the  end segment which that end segment is plus 60 so   i'm going to give here 60 millimeter plus and here also on the other  side also plus 60 and now we can connect this one we  don't have to but should be just for the picture so this is now my bend don't forget the holes so now almost done i'm gonna  punch all the now the holes in it now next thing is i'm to cut  this here out on the galantine [Music] and now of course i'm gonna use here  the electric shears to cut out [Music] okay well because it's a standing bend so the  band goes from from from left to the right   which means this is here the starting  segment the one with 200 so normally   i say here comes a swage the x is for a mil a  female swage and i said here okay 200 length then   the middle part comes also with a female swage  a male swage these signs we use here in germany   but you can also find them on a playstation  controller okay now here we have a swage female swage mill switch and  now the end part comes also   mill swage and we said the end part should  be 180 so if you have more more bands to do   in some kind of a cereal i think it's always  good to write down exactly the sizes now next   thing is what we need to do is we're going to  swage it round it and put this thing together so i have here swage wheels number one i can also use smaller or  maybe a little bit bigger but   the number one for a diameter  190 i think it's a good size so now we're going to round it [Music]   oh yeah one here are these things see just put them here in and you don't need screws   it's really quick okay okay  for the starting segment so so the first time here goes against  the plate and now i'm gonna hold it   straight here so this is here in a straight  line see i have here a lot of air under so by the next round i'm gonna push it down that's the female switch and here  also again and the same thing [Applause] mail switch so i'm going to give the  middle switch a little bit more   only a little bit and if you come by the seam  it's always good to pull it a little bit up so that that hit this one  here really close very good hey [Music] hey and the last one gets only  a meal switch [Applause] hey [Music] [Applause] [Music] okay that was a swagging part  and now let's put this thing together [Music] now if you did it right you sit always like  something like a half hole you call it a half hole [Music] that's the one the whole next one catch the hole okay [Applause] because if you're going  to fit the band it shouldn't fall out must be really good and the last one [Music] [Music] okay well that's the bed and now the  biggest question you're going to check out well it is as you can see 90 degree a little bit okay not easily maybe from here see it better you can also look inside okay well that was the 90 degree  segment band in this video [Music] i hope you   enjoyed watching and have learned something i  have i have tried to explain it as good as i can   so guys have a good time and see  you in the next video man see ya you
