How to Make a Bubble Set or Swan neck bend in Conduit

[@rogerbradbury9713]

It's been 30 years since I did this, but I would mark the 20mm tube in three places before I bent it. The marks being (I think) at 125mm spacings for a bubble set over another 20mm conduit. I'd then line each mark up in turn relative to the hacksawed marker groove that you'll find on nearly every former, then make each bend in turn. One mark would be against the groove, the other two offset from the groove by different amounts. This gave me a symmetrical bend with each mark in the middle of its bend. I would check for alignment against a handy door frame; there's usually one nearby when surface conduit is being installed. I much prefer these Hilmar benders to any other. I remember one Hilmar I used was built with round section tubing, not the square section tubing most of us are used to; it must have been a very early version.

Good video and good skills. Electricians are required to have lots of technical and practical skills honed over years to earn yhe same money as decorators

[@stefangiurgila7807]

Haha yeah

[@Mike_5]

PVC conduit installers are one thing but proper Galvinised metal conduit is a different world!

[@andysims4906]

Bit like plumbers . Plastic and copper

[@alanmarriott9216]

Great video but can I ask. On site there very rarely is a desk or work bench available so any tips on striking the line for bends would be much appreciated.

[@dexwhitmore]

use what you have; spirit level, speed square, edge of a workbench or toolbox

[@grahamshortt2525]

Great video lads . Same Hilmar bending kit but called a saddle set in Ireland and a swan or goose neck is something you do on outside lanterns .

[@mij.londoner]

A great bubble set video . Thanks for sharing My fav Elec channel.

[@Xlanzilla]

The back bends would be half of the angle of the initial bend. If you have a angle gauge on your former you can get a good approximation.

[@thattoolguy9432]

Well done Jake

[@Dragon-Slay3r]

This is why they trying to literally take me out and then say it was welldone 😭 Is this because I ate the long kebab side and the short skinny side is in the Thor bin and they used aunty as a cover for it

[@williamcuthbertson4903]

I love these videos. They're helpful. However, on a massive industrial site, I've found applying the techniques much more challenging to the point of not doing it the ways shown in your videos.

[@efixx]

Thanks 👍🏻

[@matthewcampbell9956]

Lmao they only read the first 2 sentences 😂

[@Dragon-Slay3r]

They they used a seagul to make a short paper clip behind the swan centre flats which took cover from hair straightner few months ago then so the signature bumble “spell” can be used to cover the will situation and they used a double surname of sajdah to cover death row records situation which was masked with basketball outside 3 years ago situation and a different cat left next door due to outsoor burger situation

[@impactvision]

A swan neck is a completely different bend, generally to drop into loop in/out boxes or go round external 90's without having to chase out the blockwork.

[@shanemcredmond9751]

Thanks for the helpful video. Just one question. You state, the first mark is approximate. How do we get an exact measurement for the center of the bubble. For example if i need to measure 800 mm from the back of bend to center of obstacle.

[@eanan00]

Did you find out the answer?

[@shanemcredmond9751]

@@eanan00 no, I can get it pretty good by just guessing, but I'd like to have an exact method

[@benmanning5789]

Could you indicate exactly where you need to line the black mark up on the bender please for the different types of bends?

[@charletonzimmerman4205]

In the USA, North America, we "Electricians", call it a "3-Point" saddle, one 45 degree, with both side, 22 1/2, @ ends. or 15, 30, 15.

[@MrUtube1916]

Would yous do a video on a 4 piece bridge bend? Aka handle bars? Cheers

[@Crissecrisse98]

Usually my first center bend is 45 degrees and the 2 other one are 22,5 degrees

[@joanofarc708]

This seems to be a better way

[@brendanosullivan2484]

Then to find the distance between the center you need to find the Hypotenuse, which is the opposite (distance of jump (50mm in this case)), divided by sin ((angle(which is 22.5)). So here it is Hyp = Opp/sin22.5 => Hyp = 50/.38 ==> 130mm....

[@ukclimber]

So how would a bubble set effect conduit capacity. If 2 sets is equal to one bend (a bend being defined as 90°) would a bubble set be classed as 2 bends?

[@abscomm]

How do you set the tipex marks if you don't have an inclinometer? Also, using a ruler that bends could give you some issues, but if you rotated it 90 and used its edge rather than its face you may have better results.

[@dexwhitmore]

spirit level with a 45 degree vial. Inclinometer is just a fancy spirit level

[@ThePUTNON]

Can you show how to do bridge set please

[@Alan_AB]

So. What's the difference between a bubble set bend and a saddle bend? I'm a retired U.K. sparky and learned my first saddle bend back in 1975. But I've never heard of that bubble set stuff.

[@joanofarc708]

Thanks for sharing i must try this

[@dja.selekta]

Quality Guv. Thanks

[@shinyjohn6568]

when you establish your first bend can't you put a reference mark where you handle stops on the base frame so all the bends are exactly the same... if that makes any sense 😕

[@BloodmoonDawn]

Question : I’ve been told that in the AM2s and e , that there has to be a 25mm clearance between the bubble set and the pipe work it is going over. Can you help clarify please. Thankyou

[@N-hunter]

Called a three point saddle in the US. We do simple calculations and mark conduit first, then use a hand bender. Seems much simpler and more accurate than this method

[@alfredoowns12]

Bro, my thought exactly. Regardless if it's emt or rigid conduit hand benders are way more practical for use in the field. Especially when we are running 100'-300' of raceway a day. Definitely appreciate the American conduit bending practices.

[@alasdairmacleod5638]

You'd need a pretty solid hand bender to do 25mm galv 😅

[@jparagallo]

@@alasdairmacleod5638 over here we call it 1”, and yes we have a hand bender for it

[@DasTwigster]

great head up... thanks.

[@arputharajr7842]

Please explain to Metal trunking cutting different shape

[@efixx]

coming soon!

[@joemoore9991]

That is a big bubble mind. Usually just jump over another conduit

[@Dibbo1979]

Great to see proper electrical work, anyone can house bash. When i sat the 18th the lecturer and other pupils were all house bashers, what a load of shite.

[@tpb2987]

What if you dont have a table?

[@ranpederson5482]

In America I would call it a three bend saddle.

[@mpalaskokkalis1476]

Perfect electric

[@darrenfindrick834]

Every 1” of rise there’s pipe shrinkage…….. they just wasted another piece

[@darrenfindrick834]

Lol….. these guys are real pros……. Lol hacks

[@stuartcraigon2003]

Somewhat defeats the point of all the fittings manufacturers make!

[@Andrew-bl2vo]

"Bubble "

[@kidsanjose4707]

Slow…

[@DuvalDilly]

It's called a 3 point saddle. Get your terminology correct please.

[@alfredoowns12]

🤣 that's UK terms. But still crazy how different it is out there
