How to Bend Electrical Conduit for Beginners



Sharing buttons:

hey homestead prepper I want to show you

guys a beginner's guide to bending

electrical conduit up to one inch so

this is just going to be the basics a

couple things you might need are or some

conduit vendors this is a half-inch

bender I bought back in 80s at a flea

market for five dollars this is a newer

one I don't know what I paid for that by

thirty-five dollars this is a one-inch

bender I bought at a flea market here

recently and it was twenty dollars I

know it says 3/4 rigid on it you can

bend rigid pipe which that set heavy

wallbreach 118 these are half-inch

benders where my three-quarter inch

bender is right now I'm a big ol foot

board I can make the explanation without

that bender but basically EMT is electro

repelling tubing it's a thin wall pipe

it's galvanized you see in a lot of

commercial buildings movie theaters

high-rises all kinds of places and what

you have to realize is when you're

bending this pipe we have take up and I

my first pipe bending experience was a

long time ago and we were doing some

remodeling work at the tarpon springs

eye clinic my the guy was working for a

time was real high-strung and he put me

in an office and told me to pipe it in

there and you know push the wire in and

I said well you know can you show me how

to bend the pipe and he got really

excited he said just grab a bender

grab some pipe and get to it well he

want to see fire shooting out of my feet

so I went and got some of this half inch

conduit and consequently what I did is I

bent the 90s and then I had to use a

hacksaw foxes and couplings but that it

mattered him

later when he left I was able to you

know get some of it more figured out and

you know mess up you know some of his

conduit to while I was doing it but I

don't know any good electrician now

there were many conduit whether we're

trying to learn how to bend pipe so

that's just part of the learning process

but basically this is half inch this is

3/4 and this is one-inch now these are

trade sizes these are actually a lot

larger than half inch diameter and 3/4

all that so just FYI but basically you

have five inches of take-up on 1/2 inch

and six inches on three-quarter and

eight inches on one inch and what that

means is if I put the bender right here

this little arrow like if I were to put

the arrow on that mark right there and I

were to bend this up this would Bend a

ninety ten inches tall I were to put a

three-quarter bender on here put it

right on that mark at six inches and you

add six to it that would make it 12 and

if you put it right here at eight inches

that would make it 18 so if you want it

to build bending a 90 like I'm wanting

to make for my micro barbecue smoker I'm

going to be using this 1 inch conduit

which is a pretty strong stuff I've used

it replace of dowel rods and closets

that were wood that broke this stuff

will take a lot of weight I've even done

pull-ups on it I don't know if I would

do the whole 10 foot section between

bars but you know if you're only talking

to span like 4 feet it's going to hold

up the average person now if you you

know if you weigh 800 pound is it's not

going to work but for most applications

this 1 inch is pretty strong but I need

to build it bend a 32-inch 90 so what I

would do is measure from here tape

measure

and I would put a mark right there and

if you bent it you'd be adding 32 inches

to it it'd be 40 inches tall so that's

why I might take it up to subtract 8

inches which would be 24 so if I put

this right here at 24 inches and I put

it on that arrow and I bend this thing

up it's going to give me a 90

approximately 32 inches tall so the

other way you can do it the way I really

like doing it is that the Bender is

facing this way and you put it right

there with that arrow is and you bend it

up and you're going to get a 32 inch 90

if you measure 32 inches this is less

confusing I think

you put your mark right there at 32

inches and you see that little thing

right there that little star if you put

the bender like that you're not you're

not going to get a 32-inch 9 you have to

flip it over now this is facing the

other way

and you put that on there like that and

you'll bend a 32-inch 90 you don't have

to know when to subtract or whatever

that that goes for any of these other

pipes in here just mark whatever you

want the 90 to be at you put it there

and turn to the biggest the vendor can't

be this way it has to be this way and

you'll Bend this up now if you're

bending a short 90 right here you don't

ever want to go on a job and do the

bender like this where you're bending 10

feet of pipe up in the air the other

electricians will make fun of you and

laugh at you so you know that that's why

you have to turn around do it the other

way so I hope I was clear on that Khan

conduit bending some people take it very

personal like an art I remember a long

time ago here in Florida if you lost

your job or if you got mad at your boss

you could go to another company that day

and have a job as an electrician one of

the journeyman that came to work with us

he had left the company was working for

which I'm not going to say who it was

but they had rules where they wanted you

to you know run at least 300 feet of

this stuff in the day and running 300

feet of that in a day on straight runs

it's not a problem but when you start

running it in offices and you have to

take the walls apart and all that it can

be a little time-consuming can be

labor-intensive too but he told me they

would give you 300 feet of pipe and what

a lot of guys would do is at the end of

the day they couldn't you know bend up

300 feet they would just throw whatever

they had left over open the ceiling and

you know the supervisors and bosses were

all happy that you know that pipe got

used up so anyway guys I just thought

I'd share that but let's let's see about

bending up some of this pipe and I'll

just show you all a couple more tricks

okay another thing you need to learn if

you're going to bend pipe is you need to

be able to bend an offset or some people

call it a dogleg that you got you got a

peace pipe here and if you have a piece

of a box

the the hole the knockout for the box is

a little bit higher it's not flat I've

seen people run the pipe straight and

it's a little bit off and they run it in

there and it's it's sloped and it looks

well it looks unprofessional but yet

they're very easy to ban all you do is

just put the benefit here

it's not an exact science take this and

you just give it a little a little kick

like that okay you see how it's bent

then you take it and you put that right

where the bend is you just give it

another little kick like so and that

makes a dogleg and it makes your work

look a lot more professional because

this can be strapped to the wall flat

and then that will go into a conduit box

okay I got my mark there 32 inches

that's the point where I'm measuring

from you notice which way I have the

bender is facing a weighting mark stop

at that center star see we could zoom in

a little bit see what I'm doing here

okay I got that right on there

now

okay what we're going to do you're going

to put a foot here and I've got a hand

right here we're just going to step on

this and we're going to pull it towards

us

this should measure exactly 2 inches

with there abouts

pretty close to it if you can see it so

basically that's how it's done the

problem we have is I need to bend

something like that so how do we do that

okay I just want to make the copy of

that so what we can do is just lay that

on top of that pipe with this as a guide

I can take my marker

we can just put a mark right there and

what we're going to do is take the

bender the measuring from that end the

bender faces this way just like we did

before

okay you want to make sure that you've

got the 90 up this way go here you don't

have it laying down because it will

bring up all cattywampus so we're going

to try bend this

we go see how it looks

all in this anyway

pretty much exact copy I just need to

hand Bend it out a little bit so it's

even and just whack that off right there

okay like they turned out pretty good so

just need to figure out how to space

them and I've got the set of wheels over

here

my wheels so okay I got it all finished

I'm gonna set my barbeque on top of that

I took the wheels off of the old smoker

it's pretty strong so let's get it set

on there okay I got it all bolted on

there it wasn't a lectric ajob per se

with wiring but nonetheless I was able

to use electrical conduit to make a

stand for my barbecue grill I just need

to wire wheel the thing and get it all

cleaned up and paint it and put a vent

and that in and put a out on that end so

okay guys I hope I hope that was
