EMT Bending: How To Make a 3 Point Saddle Bend Without Charts or Apps



Sharing buttons:

this is bill for Sparky Channel and

today I'm going to show you how to make

a three Bend saddle and my emphasis is

going to be trying to get you to be able

to do it without looking up any tables

or apps on your cell phone or anything

so this is an obstruction I've got a six

foot piece of EMT conduit right here and

say you're going along and boom you hit

the obstruction and you gotta go all you

got to jump over it and this is a two

and a half inch obstruction and we're

gonna clear it by a half an inch so

we're gonna jump over this three inches

for a 3-band saddle you're gonna have to

make three bends so that means you're

going to have to make three marks on

your pipe the first mark on your pipe

you're going to make at the center of

the obstruction plus the shrinkage so

you start great wherever your conduit

starts in my case this talks of this

fitting and it goes into the fitting

about five eighths of an inch so I have

a screw right here that will signify the

beginning of our content and then we're

going to measure over here to the middle

of the obstruction not to sign not

decide the middle the center of the

obstruction so you go like that that's

34 inches

so the middle of our instruction is 34

inches but this says plus shrinkage

because when you go over this pipe your

pipes going to shrink so the shrink is

3/16 per inch o height of obstruction so

we've said the we're going to jump up

three inches so 3/16 times three so

that'll be 9/16 so we've measured this

at 34 and then you add 9/16 so that's 34

and 9/16 it's gonna be our first mark so

34 and 9/16 right there now that we've

made the center mark we need to make the

two marks on either side of the center

mark and remember it's two and a half

inches times the height of the

obstruction so that's seven and a half

inches to each side of the center mark

that we're going to be making two more

marks that'll be our three marks so I've

made the center mark at 34 and 9/16 and

then the two outer marks are 7 1/2

inches on either side and I've made my

marks all the way around and have made

them a pencil before we start doing the

penny I want to show you that the center

mark will be lined up with what is

called a rim notch right here the only

thing is used for the center of a three

point Bend it's called the rim notch and

there's one on this side too

and that's what we're gonna line our

Center mark with the rim notch this is

the hook of the bender when making the

middle Bend of a three-point saddle bend

the hook of the bender can be pointed in

either direction as long as your line is

on the rim notch so the first thing I'm

going to do is put my middle mark on the

rim not right there the middle marks on

the rim notch and upend this the 45

degrees which is right there

okay we have 45 degrees then you leave

it in the bender and we're go down to

the arrow put it right there like that

and you get this in the same plane if

you don't you'll get what's called a

dogleg so we're right there the outer

mark is on the arrow we're in the plane

and this was going to 22 degrees

okay now we're gonna take this one put

it in the bender get it in the right

plane get this lined up right with the

arrow mark all right in the right plane

right there we're going to go to 22

degrees again

all right we're gonna put it down on the

ground cheese came out good so you put

it on a level to check it out that looks

pretty darn good

I'm gonna go ahead and put it in this

fitting right here and this thing over

here okay you can see I got the middle

Bend aligned with the center of the

obstruction and here's our other two

marks over here okay so the next thing

to do is to use a little cleaner and

clean off your pencil marks okay you see

I've cleaned off the pencil marks and I

think it looks a lot better that way I

think it looks a lot more professional

so there's your three Bend saddle so in

review your first mark on your pipe is

at the center of the obstruction plus

shrinkage okay and the outer marks the

two outer marks are two and a half

inches per inch of height of instruction

so if you have three inches of

obstruction it's seven and a half inches

on each side of the center line and the

shrink is 3/16 four inch of height of

obstructions now if you look on your

ideal bender here it's not on there and

it's not on my client better handle

either so I actually wrote these things

on my bender so three bins saddle two

and a half inch 4 inch 3/16 inch per

inch of free here's a real nice table

for a three point saddle bends and here

we have the 3 inch obstruction nine

sixteenths shrinkage and seven and a

half inches between bands and it will

give you a link in my video description

for it it's been slow does this memorize

this stuff your work way faster that way

so if you can just remember these simple

rules and you're using the 22 and a half

45:20 two and a half degree format then

you can make any three-point saddle band

at any time without consulting any chart

or app or anything I'll put links in my

video description for the Cline magnetic

25-foot tape measure with conduit

bending tables and for the Cline digital

magnetic level I'll also put links for a

Cline and ideal conduit benders in the

half inch three-quarter inch and one

inch sizes both in aluminum and in

ductile iron and I'll put a link for the

Kline full brim hardhat I'll also put

links for our Cline kneeling pads what's

really safe wear and tear on your knees

thanks I hope this video was helpful
