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?

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.

On 20mm its about 50mm from back of the former,so mark former mark conduit and bend you could mark conduit say 10mm longer for your first bend and adjust mark on former to suit

Who cares, just palm it off on a pipe fitter! :smilielol5:

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.

Bloody amateur!!

Thank God you're just a spark and not a plumber!!

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.
