Doing some steel conduit bending (90, single set and double set) but can't find anything online of how to do it or such, can anyone direct me to some posts/videos on how to bend them?
Thanks,
Kieren

I didn't check any of them out but if you type the term "Conduit bending" into youtube you may get a pleasant surprise. About 6 seconds work that was.

buy some pipe and have a go yourself, no need for videos, you will need to mark your former as well, I cut a grove in mine with a hacksaw so the bend is right every time, however 2-3 attempts may be needed to get it right, bending pipe and becomming a conduit commando is all about practice not videos IMHO.
I found the document below a useful reference, particularly with the explanations on how to approach 30 / 45 degree sets and bubbles. From page 27.

I was trying to look on YouTube but it's blocked in college, so couldn't check yet. Thanks Happy Jack, got a lot of useful stuff in there 
There is, isn't there! Although they refer to the ETCI, Electro-technical Council of Ireland, each rule appears to align with BS7671 to some extent, and component / accessory parlance is identical. I would, however, err on the side of caution and cross-reference for accuracy before acting on any of the guidance there.
A number of their course notes are available online, so would assume available for public reference, else it would be stored securely via their intranet or other means, surely.
I link to their 'portal' below, which I've found a very useful resource; their literature is peppered with real-life photographs and other such references, which makes reading a little richer and informative than some of the B&B handouts. In my opinion, of course.
To the mods, please remove this if this isn't appropriate.

Plus a mentor who will patiently show you how to do it then supervise you while you do one, and who will slap the crap out of you if you bugger it up too many times.
Worked for me
its practice.
i had 2 days at work of bending conduit last year, glad work we do is so varied as i dont find it too bad now.
a lot of skill in making a good piece of galv

Perhaps, but I doubt the OP has a bending machine at home.
Thanks Marvo.
I remember one of our tutors explaining the formal method of produce concentric / segment bends. I remember thinking at the time that doing it 'by eye' was surely impossible, and that without knowing the method, you'd had nothing to gain from any practice. Unless you wanted to practice getting things wrong. Repeatedly.
There is some value in having a reference unless you really are that capable with the stuff.
always more satisfying doing it by eye then grabbing tape to make sure.
(i have used plumbers method of using piece of paper but tend to work to back of bend)

When I was at college my dad hired a bender for me 
He stuck me in the garage with about 20 lengths and told me to get to work, needless to say I worked up a bit of sweat but I got my technique just right! hahaha
Treat the bender well, give it some attention and some tender loving care and you will be rewarded my friend

I do, he can always come around for some practise, I can show him how to make nipples :biggrin5:
You are correct Sir, I do not have a bending machine at home.
And MDJ, I'm not sure if I like the idea of making nipples...
It'd be cheap as chips to hire one for a week! Add a few quid for some lengths of galv and robert's your fathers brother

when I was an apprentice I used to spend all day making nipples, you will have arms like popeye with practice.
not that tricky.
put conduit in bender and rest bar on top.
then using an off cut (put it with side facing up so makes a T then set square (or easy method and use groove/mark on bender)
this is the centre of your bend.
now it depends if you were asked/are measuring to end off thread or couple/centre of box.
seriously its exactly the same as the plumbers method just the benders have a slightly different forn but you use them the same

Not sure if that story would be suitable for a public forum mate :shades_smile:
