Man, that makes so much sense. I have been struggling for years with pipe bending. I always made it work out, but it was something I always dreaded when going to a job and having to do it. Gonna check out the rest of your channel. Thanks.
I am quite embarrassed to say it but I've been in the trade for 15+ years and have never known to put the pipe in the bender like at 1:22 to hold it while i cut it! I have never seen anyone else do it either. Such a simple and effective way to stabilize the pipe while cutting. This will save me from using the old knee vise method lol. Thank you so much!
Bill, have you ever seen the equation for marking for multiple bends before bending? Using the gain and shrink for the total length? for instance, taking 2 90 degree bends that are kind of stair stepped to one another. say you have a 12 inch stub and a 18 inch stub. and a back to back measurement of 60 inches and let's say the gain for this 3/4 inch bender is 3 1/4 inches. you are supposed to be able to add each stub and the back to back measurement, which is the distance from one end of the conduit to the other since there are only 2 90's in the run. the stubs plus the back to back measurement is 90 inches and you subtract the gain of each stub, which is 3 1/4 inches each. when I subtract the gain of 6 1/2 inches from the 90 inches, I have 83 1/2 inches left. I haven't been able to test this since I'm presently laid off and waiting to go back to work, but when I measure it out in my head: I deduct the 6 inches for a 3/4 inch bender for take-up, 6 inches on the 12 inch stub and 12 inches on the 18 inch stub; I have 65 1/2 inches left between my marks; now, if I deduct the 6 1/2 inches for the gain, I'm actually short 1 inch for what I need. The same equation worked on a section with 3 90's. What do you think of this manner of equation, Bill? Have you ever used it, and would you be willing to demonstrate it on your channel? thanks
@@SparkyChannel I wouldn't mind a video demonstrating common problems and corrections to conduit bending. I always seem to overbend but I don't always know how to correct it. Just a suggestion. Thank you again.
@@SparkyChannel hi Sparky im a apprentice electrician and im new to conduit bending can you explain what are multipliers and shrinkage and how to use it in the field ?

No, the bends make the conduit shrink by 1" so you would cut it at 39" after making the bends. Or just cut the conduit at 40" then make the bends. It will "shrink" to 39".
@ 2:56 you said to get a 40” piece you would cut it at 39”. Since you have a shrink of 1”, wouldn’t you want the overall to be 41” to come out to be 40”?
I suppose he meant after you made all your bonds. It was a bit misleading but he needed a total length of 39" with offsets as he alludes to at 0:48 . I had to rewatch it as well to confirm. @sparkychannel always produces such great content and the bending library he's created is outstanding.
A N, Lets say you start with a 40" piece of conduit. Now make your bends and because of the bends the overall length is now 39". The conduit "shrunk" as we say. What I'm saying is that you can take a longer piece of EMT, make the same bends, and then cut the bent-up EMT at 39". It will come out exactly the same.
I have a question that has always confused me, if I want to go over a obstacle, say a 1” drop ceiling grid. Where I my first measurement to get the offset closest to the obstacle? I know that if I’m using 10* I multiply 1” x 6 but where do I start those measurements from my box ?
It's hard for me to tell what happened without seeing it but I would guess that you have a hot wire touching a neutral or a hot wire touching a ground.
@@SparkyChannel well it’s confusing what I’m trying to ask, but say my box is on the wall and it’s 48” from top of box to the 1” obstacle I need to go over. My multiplier is 6; my second mark is 6” from the first mark but where do I make the first mark? At 48”?
Question I have is that I've been trying to find everywhere is, are the multipliers the same for different size conduit? If you use the same multiplier for 3/4 on a 1" it's a bigger radius pipe and the shoe on the bender is bigger. If you use same multiplier of 3/4 for a 4inch offset on a 1inch it ends up being like 7 inches.
The multiplier he is talking about is the 4 inches of obstacle the needs to clear which it was 4 inches, so 4 inches x 2 multiplier = 8 inches, and he put his first mark at 6 inches from the edge of the pipe but that's what he was using you can make that first mark however fits your bill best , so again 6 inches from the end of the pipe for the first mark the second mark needs to be 8 inches away from that first mark to clear 4 inches of obstacle 4 x2 multiplier= 8 inches, so 6 inches first mark + 8 inches second mark = 14, 6 inches for the first mark and 14 inches for the second mark from the edge of the pipe... hope this helps and makes sense
6" is just the tail, when you bend pipe you can choose your own tail length. Then from that first mark you measure from that to get your second mark aka the multiplier amount.
@@lancec6342 Thank you Lance. Since my last inquiry, I have been working with my JW, bending offsets of various lengths. I am also working with Rigid pipe for the first time and bent an awesome 3 point saddle on the Chicago bender!!
IDEAL gave me those gloves at the IDEAL National Championship. They're really nice but I don't think they are for sale. Playlist for all of my competition videos: IDEAL National Championship 2019 Competition Videos from Sparky Channel: ruclips.net/p/PLSD43kAzjUIRfq58lAqj2dXKhTY_8QaDO
It is a 4 inch offset. 8 inches between the marks. The 6 inch mark from the end of the pipe was just for the tail. There isnt a specific point you have to put your first mark. So, if you decide to put your first mark at 6 inches, you measure 8 inches from the first mark to your second mark. This gives you a total of 14 inches from the end of the pipe to your second mark.
It's true for all benders but the correct way to say it is when the bender handle is perpendicular to the ground because maybe your ground isn't really level.
in your other videos you show the obstacles and how measure them but this one you just told us it was an 4 inches obstacle. i wish you could had shown a wall with ostacles like most of your videos is helps alot when i see your other videos but this one was a lil bit confusing
Just imagine running a conduit on the side of a house, and you have a chimney/architectural design that is bumped out of the wall 4"+. You could use this 30 degree offset to continue your run
At 4:13 Shouldn't the offset be measured from centerline to centerline, or at least from the same side of each conduit? Looks like you measured it from the bottom side of one to the top side of the other which would result in a measured amount off by the diameter of the conduit?

Thank you so much for explaining how to calculate the height I was having trouble understanding why we need to use the multipliers.

Thanks Johnathan!
Somehow I got here from Futurama. Interesting knowledge of the day. Thanks
Thanks for watching!
Thanks teacher sparky channel for keep us teaching stay healthy and safe
How do you know how far back you make the first mark? I’ve seen people do 3 or 6 or another number
Thank you so much for good teaching
Great video.
Thanks!
Great lesson.
Thank you sir, very helpful
Glad it helped, thanks!
Very helpful, thank you so much!
You're very welcome!
Is there a video showing how and where to measure to get the amount of bent needed
if the offset bend shrinks the conduit by 1", wouldnt you have to cut it at 41" instead of 39"?
No, the bends make the conduit shrink by 1" so you would cut it at 39" after making the bends. Or just cut the conduit at 40" then make the bends. It will "shrink" to 39".
Sparky Channel oh I see. Thanks for clearing that up
Exelente video!! Gracias my friend..
No problem, thanks Efren!
thank u for this.. helps a lot...
@ 2:56 you said to get a 40” piece you would cut it at 39”. Since you have a shrink of 1”, wouldn’t you want the overall to be 41” to come out to be 40”?
I was thinking the same thing

Although he may have had a hick up i still understood what he was teaching. Really good man 🦸♂️

Are these calculations all the same regardless of emt conduit size?
No
where do you get the 6’’ tail from?
It doesn’t matter, he just chose it. You can choose whatever you like too. Like he said it’s arbitrary.
Do you mind making a video on rolling offsets
Thanks!
No problem!

Welcome
Question I have is that I've been trying to find everywhere is, are the multipliers the same for different size conduit? If you use the same multiplier for 3/4 on a 1" it's a bigger radius pipe and the shoe on the bender is bigger. If you use same multiplier of 3/4 for a 4inch offset on a 1inch it ends up being like 7 inches.
If I need to get to two Four Square Boxes, which one is better? Make first my box offsets or my 30 degree offset?
Thank you for your great videos I have a question what degrees should I use for a 3 bend saddle when I have an obstacle of 1” diameter???
45 first bend, 22, 22
Hello Sparky. Not understanding how you got 14" as the second mark if the multiplier is 2? 6 x2 is 12...
The multiplier he is talking about is the 4 inches of obstacle the needs to clear which it was 4 inches, so 4 inches x 2 multiplier = 8 inches, and he put his first mark at 6 inches from the edge of the pipe but that's what he was using you can make that first mark however fits your bill best , so again 6 inches from the end of the pipe for the first mark the second mark needs to be 8 inches away from that first mark to clear 4 inches of obstacle 4 x2 multiplier= 8 inches, so 6 inches first mark + 8 inches second mark = 14, 6 inches for the first mark and 14 inches for the second mark from the edge of the pipe... hope this helps and makes sense
@@tattooaddicts23 So 14 inches total: 6 + 8 = 14 from the edge. Thanks friend*
6" is just the tail, when you bend pipe you can choose your own tail length. Then from that first mark you measure from that to get your second mark aka the multiplier amount.
@@lancec6342 Thank you Lance. Since my last inquiry, I have been working with my JW, bending offsets of various lengths. I am also working with Rigid pipe for the first time and bent an awesome 3 point saddle on the Chicago bender!!
The distance between 6 and 14 is 8
The measurement was 4 multiplied by two which is 8. 6 was starting
Is the shrinkage all the same for conduit 1/2", 3/4"and 1"?
I think the 10° multiplier is a little generous at 6. May I suggest 5.8 since you're taking it out to one decimal point?
Yes, you may. Thanks!
Fantastic
Thank you! Cheers!
Im doing this same method fpr 3/4" rigid and it's not coming out right
ridgid uses a next size up bender the multiplier is relatively the same. Your technique might need to be adjusted or addressed
3/4 rigid I believe uses 1” emt multiplier and shrinkage
Where can I get a pair of gloves like yours?
IDEAL gave me those gloves at the IDEAL National Championship. They're really nice but I don't think they are for sale. Playlist for all of my competition videos: IDEAL National Championship 2019 Competition Videos from Sparky Channel: ruclips.net/p/PLSD43kAzjUIRfq58lAqj2dXKhTY_8QaDO
I’m lost. 6 x 2 is 12. Not 14. Did you add two extra inches because of shrinkage ?
Most likely because 90 degree bends will take off 5 inches if I remember so now imagine 60 degrees.
I was confused to. 6” was how long his tail is and he’s doing a 4” offset the multiplyer is 2x4=8. 8” from his original 6” mark. 6+8=14
He means 4x4 because 4 inches is the gap and 6 inches is the tail
It is a 4 inch offset. 8 inches between the marks. The 6 inch mark from the end of the pipe was just for the tail. There isnt a specific point you have to put your first mark. So, if you decide to put your first mark at 6 inches, you measure 8 inches from the first mark to your second mark. This gives you a total of 14 inches from the end of the pipe to your second mark.
Are these degrees, multipliers, and shrinkage the same for rigid conduit?
Yes.
Is the 30 degree while the bender straight only for ideals ?
It's true for all benders but the correct way to say it is when the bender handle is perpendicular to the ground because maybe your ground isn't really level.
I have a question on the Gray PVC Condo it how do you bend it🍺😃🍔
That will be another video down the road. Cheers with burgers and beer!

he measured from bottom to bottom instead of middle to middle
How do you know the tail length
dude every video doesnt tell you.
@@austinreeves5221 the tail length is whatever you need it to be I work with IBeW and I failed my Bend test 💀
