Ok, but what is the application?? They have tubing benders, and expanders and reducing jigs for that. What are you fabricating? A muffler for a lawnmower?
I could never remember all that folding... lol heres how I'd simply do it: Take bigger diameter and retract the smaller diameter. Split the difference in however many sides you want (3 for a square, 5 for a hexagon, 7 for a octagon etc.) The result is the width of each triangle cutout, all you have to do is space them out evenly... how far you cut your triangle into the end of the pipe determines how steep/shallow a transition you will get... Bobs your uncle....
@@ronaldgraham8449 yeah, leave my uncle out of this! Becides, he would understand what you stated anyway! However, even I understood this great vid as did my 14 year old, (not bob).
Yes, but measuring and marking is a different thing than calculating. Subdividing an arc and getting precise and parallel tick marks is difficult without a pattern.
Don't be discouraged by the critics below, as this is a great video. Keep up to good work. The critics may have learned other ways but what they haven't learned is empathy or patience. Dhaaaah, what question?
This is the type of shit someone does to their exhaust and lays a bubblegum weld with tons of leaks because they can't weld for shit laying on their back, then brings it to me when they can't get it sealed and says "can't you just weld it up?"
I've worked on oil rigs where running to a parts store isn't an option. Also a mobile mechanic and sometimes in the middle of nowhere, and these types of fixes, when done correctly last for years. Not to mention it's a good way to help the environment by not purchasing something you don't need.
@@glumreaper8885 yes, they do very much. If we need to have oil, then we need to find other ways of helping our planet. Little things done by millions of people add up to alot.
Or in the same amount of time, run to the parts store and get the correct reducer like a professional. While you're there, buy some gloves and a guard for that grinder.
@hey guys This is a trash method to make money. I'm sure some shade tree hobbyist with 110v Hobart using innershield throwing bird crap at a rusty exhaust on a $200 Ford Ranger might do this. Or some hippy making yard art out of junk. A reducer is $4. The cut off wheel is $5, plus the time to do all the measuring, cutting and fitting. Anyone doing this lost money. Just buy the right parts.
@@johnsaa7325 Wrong. I've been through both OSHA and MSHA training. As well as being a safety supervisor at a massive fab shop. Wearing gloves while grinding is just the opposite of unsafe
Most welders cutters and fitters would not do this because they have tools that give them the measurements and knowledge of where to make changes at. Now, this would be handy when you do not have the right equipment
Есть формула для переходов , диаметр б трубы , минус диаметр м трубы, умножаем на 3.14 , и делим на кол-во вырезаемых сегментов, в итоге получаем ширину вырезаемого сегмента
@@alterstassfurter5743 if you use translator on two upper comments, yo'll understand tha't author is taking hard and timewasting moves instead of simple math. zoomers VS geometry it is.
@@user-xf9uk9xr9w Причем можно высчитать настолько точно, что малая труба будет вставляться в переходник, или стыковаться кромкой. Для этого необходимо учитывать толщину стенки и делать расчет по внешнему или внутреннему диаметру трубы. На видео показан вариант для тех, кто не учил математику ;)
En resumidas cuentas...dividio la diferencia de tamaño en 8 partes ...luego le saco 1/8 al tubo grande y magia.....muy buen razonamiento. Para calcular y ejecutar..
I work for a very large gas and electric utility. We have so much pipe in the ground with home made reducers like this. But like 16" to 6" with 60psi of gas in it
And not have the disk spinning directly towards your very vulnerable wrists so any metal shards or, of course, high velocity chunks of particle disk, fly off and sever arteries or tendons in your wrist if the disc explodes.
@@jonathanfinger712 yes, but when it stars to grind the glove you've got the time to remove your hand. I always use thick leather gloves when I use an angle grinder and dispite all my care sometimes they got bite by the grinder (especially after several hours of work). But once I forgot my gloves and it nearly cost me a finger (not a playword lol !!)..
A piece of string works... or just cut your strip over length, then do the "wrap and lap" he did for the smaller tube. As to width, just double the dimension you want for your conic transition, which can be anything from half the difference in diameters (a square flange transition),to the full length of the larger diameter (a very gradual conic transition) tube. The technique works at both extremes, or anywhere in between. The only difference is length and angle of your waste "dart" cut drops
And sometimes, you just got to make it work "right now". In the military we called it, "Field Expedient Repair". When you don't have a retailer nearby, you need skills.
Hi guys, excelent to know , just in case!, I see a lot of comments about security, to pick up the correct adaptor, gloves " guantes" First sorry my english, ours grandfathers sertenly will appreciate this method. And the world is not the same in diferents countries In my place, impossible to get adaptors and a lot of things. Thank you for share your knowledge body!! Tucumán 🇦🇷 Argentina
There's no reason to appologise for your English. You can speak at least TWO languages. Most 'native' English speakers - usually those who deride people whose FIRST language is not English - struggle to even speak English correctly. No hay razón para disculparse por su inglés. Puedes hablar al menos DOS idiomas. La mayoría de los hablantes de inglés 'nativos', generalmente aquellos que se burlan de las personas cuyo PRIMER idioma no es el inglés, luchan incluso por hablar inglés correctamente.
Sou serralheiro e projetista, existem muitas formas de fazer o mesmo trabalho, cada um faz da forma que deseja, que gosta e que sua condição permite, parabéns pelo video e continue com o ótimo trabalho.
Psk, that is what he did - graphically instead of mathematically. The cool thing about the way he did it is that it’s easy to make the marks around the pipe without any extra figuring, measuring, etc. By doing this the marks are automatically equally spaced around the pipe without trying to bend a tape measure around the pipe. And he also sets the location of the tip of the triangle to cut out at the same time.
Yeah... This Is DIY... So It Mean This Things Is Suitable For A People That Are Not Affordable To Spend A Lots Of Money On Somethings... Same As Me... So This Type Of People Ofcourse Does Not Have Much Money To Spend For A MIG Type Welder... Same With Me, Maybe They Will Have A Cheap Type Welder, Arc Type/Rod Type... It Is Really Hard To Weld Thin Plate Using Rod... If They Got A Money To Buy MiG Welder, Im Sure It Is Better They Buy A Joiner/Socket To Connect Those Pipes Than Doing This Thing....
@@DS-mm6fh Ofcourse We Can Braze It... It Is Much Easier... But As I Mention Before, We Need To Find That Tool For Brazing... So It Will Cost Us More Than We Buying Socket/Joiner... As DIY Concept, We Save Our Money By Using Our Ready Tools And By Do-It Ourself... Not Much People Having Brazing Tool... For Me, Yes I Have It Because Im Doing Metal Works... But For Other People, I Think A Lots Of Them Does Not Have Brazing Tools Compare To Rod Welding Tools... For The People That Already Have MiG/TiG Or Brazing Tools, Ofcourse They Can Used It... It Is Easier And Practical...
These videos are so funny because these “hacks” take like an hour or more of intense work and there are very cheap adapter and fittings for all this stuff.
Nice, until that cutoff wheel removes human hand parts. No guard? no gloves? and the pipe should be in a vice so that the grinder can be properly controlled. Lost fingers or cut hand tendons could be the bigger lesson learned here.
