How to mark conduit bender?

[Alan Marriott]

Good evening Gents

Om after some help and advice please on setting up a new conduit bender.
Im wanting to ask how to score a mark on the forming wheel to indicate bending points etc?

I usually do the way of doing a bend then offering up and trimming excess off but would like to learn the old school way of measuring exactly please and seen many formers with marks on for bending points and wondered how the find it out please!?

Thanks

How do you get over the problem of not being able to screw the conduit together?

Conlok (ew gross). Running couplers don't look that bad, better after painting. I think they look cooler with lock nuts rather than lock rings.

oh no. Always lock rings, lock nuts should only be used inside boxes.

They do look slightly untidy, but they are necessary whenever you can't spin the conduit due or bends/obstructions or the conduit is just too long to assemble on the floor and lift into place.

I have never heard of a running coupler. Learn something new everyday. But then I have never had the need for them. I think they look a bit untidy though and would spoil the line of the conduit install. Although I can see they would have their uses.

Don't think they would look unsightly in an industrial install though, having used the extensively.

Remember showing one useless kid how to do one. I left him for a couple of hours to carry on and when I returned he was still struggling with it and I had to give him a nudge and tell him he needed to fit the nipple...still trying to screw the long thread in..

Did you make your own or buy ready made (nipples that is)

few times when a runnibg coupler has beed advise, I've unscrewed he box, screwed it onto the conduit, the refitted. saves a bit of Galvafroid anyway.

All depends. Usually some manufactured available, if not, no problem with a bit more arm work.

Something for a bored Apprentice, "here you go Son, stocks and dies pipe vice and a length of 32mm BE conduit, twenty nipples please cut them the same length as a normal 32mm coupler, oh and here is some Tallow to help cutting the thread, you won't need your Gym subscription this week either" see Sparking is give and take pays your wages and keeps you fit. wash your hands before you eat your Maccy Dees, there is enough grease in them as it is.

….and some of today's lads even use a machine to cut PVC conduit, eh?

Attached is the best written instructions I have seen on bending conduit. They are Irish and quite old but the basics are the same.
The best way of making offsets and bends I have found is to draw the required shape on the floor in chalk, then offer the conduit against the drawing to see where the bends should be.
On a different note it was once pointed out to me that there is a difference between the way Scots and English do conduit and having looked about it seems to be true. Scottish apprentices are taught to always use a lock ring with every thread cut, whenever you screw on a box or coupling there should always be a lock ring in there. And I have heard of guys being pulled up at their trade test for not using lock rings. In England lock rings are used much less frequently. Has anyone else noticed this? or knows why it came about?
