Where is the back of the bend on the conduit former?
have a look at plumbers guide
hold an offcut at 90o to the conduit and that will show you centre of bend

Who uses conduit these days?
tube is tube, i was taught by both a plumber and electrician when i was at college and other than multiple names for the same thing the principle is the same.
i can make a framework up in the workshop then take it to site and no need to tweak so i think knowing how plumbers dose it is very useful.

Basic college stuff this!
2.5 times the pipe diameter = 50mm or 62.5mm or whatever. Hacksaw cut in the former that distance in from the top.

As boydys post earlier
my tip for a double set is get the first one correct.
then mark it out on the floor
return to bender.
make second set to match your outline marked on the floor.
result spot on double set.

Haha Geordie !
mind we have to get wires down the pipes and not just a dod of waater now.
i should have actually said it was a method shown to me by an old boy to get matching double sets around a dirty great beam.
i don't see many plumbers doing 2ft double sets these days....
usually a bit of speed fit with a few push on elbows seems to about the limit just now.

I found silly little tips and tricks help with tube bending, I learnt from several sparks when I was a apprentice and adopted bits of all of them to make my own technique.
But 2 uncommon ones that I found help alot is:
1) Get a little magnetic bubble level (the 360 degree type) and mark on it 30, 45 and 90 degrees. Then stick it on the side of the bending handle perfect angle every time!
2) After you have set up your bender and you have marked the position for the back of bend (always worked from the back
) transfer the mark to the former to save time in future, We tend to nice ours with the hack saw so it doesnt dissapear LOL
3) As someone said above make it up on the floor first, Its easier than trying to do it when up steps!
Oh and Besoeker, I dont use it since I changed jobs recently but before that I used PVC and galv on a regular basis.
There is nout more satisfying than taking a step back from a nicely done conduit install and thinking "yup I did that and it looks the dogs danglers!"

There are lots of tricks but when you have been doing it for years and were a properly trained apprentice, it just flows, 2nd nature. Geordie knows what Im saying.

Exactly!!
That said, there's some good useful stuff on you tube showing exactly how it's done.

You tube - seems entirely appropriate.

You would have liked my last “conduit” install in the casting shop. It was close to the hot metal so the best thing to use was 1” black iron pipe.
One of the other shift teams had originally used SWA, that lasted ½ a shift. Galvanised conduit came next, that succumbed to the production lads cleaning iron splash off with a windy pick.
Before anyone asks, we would always try to avoid the danger spots. Sometimes they couldn’t be avoided and drastic measures were needed.

Are you being serious? please reply so I know whether to laugh with you or start ripping you

you mean you ----, oops sorry I remember now :leaving:
Measure the distance from the fixed point to the object you are passing over, call this measurement A. Now measure the depth of the object, call this measurement B.
Subtract B from A and mark conduit.
Now you need two 600mm rules, one of which will adjust for the angle. Now subtract B from the 600mm rule, place the other 600mm rule and adjust to new measurement, this is your bending angle.
place conduit in bender and position mark so it sits on the edge of the former. Bend to the angle of the adjustable rule.
Now remove conduit, and place so a parallel line set to measurement B is below, now mark conduit where the conduit crosses that line.
Again place in bender and place mark so it sits on edge of former and bend until parallel with conduit.
You will get perfect sets and less waste.

You forgot a final....remove from bender ...
Oh and file off the vice marks and paint vice marks and all bends.

No matter how good the vice or the grease is the conduit will need touching up.
A good vice will leave smaller teeth marks than a bad one but the marks will still be there.
D
davesparks
What make of vice are you using? Mine has teeth at least twice the width if a normal saddle.
greese and rag is all you need usually or a file on an old vice
D
davesparks
But the teeth of the vice still bite into the galv or enamel.
Galv and enamel can and will crack off at the bends with the carp quality of pipe these days and whatever you do there will be a slither of bare metal at each joint. Plus the guide on the stocks will scratch a bit as it goes round.
Painting the conduit is not just about what it looks like, it's to maintain the protective coating of the conduit.

i didnt add a rag to the list but would use it with treflex on galv.Time to change your college Shanky, or demand your money back:6:
Boydy
not the way i would do it, answer me a question
what is the point iin spraying cuts on pre galv trunking etc in a boilerhouse?
it will rust like a bastad anyway
D
davesparks
The point is to repair the galv coating wherever it is compromised.
You should use a 'zinc rich' paint of some kind.
If you know for certain that it is going to rust despite being properly treated then you shouldn't be installing it there in the first place!

I can honestly say I have never painted galv tube.
But then I have only ever installed it inside so it doesn't really matter lol

If you cut it, you paint it.
If you bend it, you paint it.

These days I end up painting every last inch of it, matt black is the order of the day for everything in theatre land!
Now black tube thats something i dont miss!
Orrible crap that was!

It's not black tube, that is way too shiny, its galv tube and a few tins of matt black spray paint.
Nothing escapes the paint! tube, trunking, tray, switches, sockets, apprentices all get it.
Yup horid stuff!
Used it the once in college and never again since. Plain galv is king lol
But PVC FTW
