    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

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

    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 .

      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

    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.

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

  • @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.

    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.

    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.

    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

    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.

    • @brendanosullivan2484
      @brendanosullivan2484 11 месяцев назад

      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....

    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.

    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.

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

    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?

  • @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
      @alfredoowns12 Год назад +2

      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.

    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.

    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

    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 😕
