Thanks, Sparky. I'm in my second month of electrician training at UEI and these videos are GOLD. I'm trying to get through the entire series because they get to the point and come from field experience, not sterile lab environments. I Appreciate your efforts Sir.
Hello, sir. I've been working as an electrician for 7 years now and wanted a quick brush up on bending. This was the best explanation I've seen for bending (also enjoyed your 3 point saddle video). I'll be forwarding these videos to my apprentices! Thanks for taking the time to make these videos!
Question, for the 3rd mark added on the conduit being 7 1/4” away from the first mark made; is that measurement the actual width of the obstruction? And if it is, is the 3/4” shrinkage factor applied to the width of the obstruction as well? Or is it not added? The first mark is distance to obstruction plus 3/4” so it’d make sense to add 3/4” to the width of the obstruction right or no?
Hey Bill, glad to have you back! Just wanted to say your old videos of pipe runs helped me figure out the math involved back when I was non-union. Now I'm in the union (IBEW local 58 Detroit), and getting a great education, but I still love the way you do your walk-through demonstrations!
Great video! How things have changed over the years! Remember learning to bend conduit, was told to write this down, then told get to work. Years ago it was a complete sink or swim attitude in the industry, even the apprenticeship was designed around weeding out the weak, started off with 140 student and ended up with less than 20.
Man I have been a sparky for 11years and I still find very valuable knowledge on your channel ,even if In this case it's about a new tool!!! Lol 🤙 god bless you sir!
@@SparkyChannel glad to hear I think everyone has their own tips and tricks just like my journeymen tell me, I’m a second year apprentice in trade school in the IBEW, I appreciate your response sir!
Hey Sparky, love the vids.. I'm starting school next week.👍.. yesterday I did a 4 point saddle bend came out great.. my journeyman just gave it a little tweak.🤙. Gonna go back through your vids and try to get ahead of the guys in class. Thanks for your wisdom.
I found your video by accident, but I have subscribed and found your explanations very easy to understand. I used your 3 point technique today and it was perfect !!
Just a phenomenal channel!! Thank you for everything Sparky Channel!! You make me realize that everything is pretty simple and that I just need to quit overthinking it. 👍 Edit: four bend saddles used to give me headaches when I was an apprentice
I don't like bending on ground but I like your idea as water level degree Marks are more accurate. Hard to get right degree when bending in air. I know few electricians who use rim notch as their marking on conduit which is easy and less complicated. Thanks for all the videos
Another great video! Question for you: the other day (not the first time this has happened) I had to bend a saddle close to the end of a stick of pipe. What is the proper way to measure and mark for the "push through" method? I made it work somehow, but wondering what I should do next time...thank you!
I have a question. You have your first marked 33’7/8” because of there is a 3/4” shrinking this one I understand. However why don’t we add another 3/4” on the other side? So that should make 1’1/2” shrinkage in total.
The other 3/4 of shrinkage wouldnt appear until after the second set of bends. If he only did the first offset there would only be a 3/4 difference from the original length of the pipe. The distance you have to cross over your obstruction won’t grow or shrink so the center point of the bends should be a constant. I’m not sure if that made complete sense. I’ll think about it and try to figure out a better way to word it
@Sparky Channel: Could you do a show on how properly air bend 3/4" conduit. It's pretty difficult and FAILED HARD on 3/4". I tried doing this several times with 3/4" conduit, and messed up each time. The last time, the conduit and bender slipped in the air and I got injured badly. Both my left little finger and my left big toe got seriously SMASHED when it cut loose. Enough so they both turned black and I'm losing my fingernail and my toenail now..
I watch all of your videos. You have so many ways for 4 bends and 3 bends. Some push through and some traditional. What is your go to methods while in the field?
He did 30° bends and shrinkage for them is 1/4", obstruction is 3 inches, 3 times 1/4 is 3/4. So he lost 1 1/2 on the full stick because the two bends each lost 3/4 × 2 = 1 1/2
Klein should make tape measures with the back side having essential conduit info, concentric bend formula, ohms law etc but skip the inch measurements on the back. Also tape measures need to be slightly compact not a big block. They need magnets on the ends that won't break off.
Hey i like the video!!! but isnt that arrow on the bender that you were using for offsets only meant for 90° bends? I thought you were supposed to use the notch for offsets
Does the multiplier or shrink change with different size of conduit? So if the multiplier for a 1/2 inch conduit is 6 will the multiplier for 3/4 inch also 6?
Inside mark bend, outside mark bend *flip conduit around* inside mark bend, outside mark bend. Finished. And all from the ground (for better results) Try bending 45+degree offsets this way and you’ll find the plain of the pipe is directly in contact with the handle.
Hi David: I just made a video that should answer your question: EMT Shrinkage To Make 3 Point Saddle Bends: Save $$ by Knowing EMT Shrink Calculations: ua-cam.com/video/Xfsk74ffdpQ/v-deo.html
He only accounted for shrinkage from one side of the conduit. 3/4". HOWEVER the actual shrinkage is double that amount because you are doing twice as many bends. How do you account for that extra shrinkage?
30 degree triangle is a special triangle with adjacent = sqrt(3), opposite = 1, hypotenuse = 2. Scale that up to match the opposite (height) with 3" requires multiplying all sides by 3", so the hypotenuse becomes 6". Also the shrinkage factor is just (hypotenuse - adjacent)/opposite, or how much more length along the pipe compared to the horizontal length, all per unit height gained (it's actually like 0.267" per inch for 30 degrees). The steeper the bend the less accurate the triangle approximation works, since the bends have arc lengths that aren't actually at sharp angles.

LOL! Good one, thanks! 2 more EMT bending videos coming this weekend. :) Check them out if you get a chance.
I was thinking the same thing lol. Sounds just like him
That is spot on..😆
Thought that the other day from one of his videos
But the difference is this guy is cool. Scotty kilmer just preaches Toyota and says everything else is junk
I just started my 1st year apprenticeship and I have to say that I'm learning alot from your videos. Thank you so much.

The other half comes off the other side of the pipe so you only add it to your overall length, but you don't need a mark on the pipe for it

I like the way how you explain things up. But the question is ? Do you just add the shrink once or you add it on to both side ?
Very informative!
I like to use center of bend for everything. Especially for saddles, that way I can just use the push through method.

Boring for the pros, fascinating for us amateurs. --- Thanks for the great upload. ---

For the 3rd mark, it’s the distance across the obstruction minus shrinkage?
Why would you MINUS for shrinkage? Use your head

My pleasure, thanks Georgio!
I watch all of your videos. You have so many ways for 4 bends and 3 bends. Some push through and some traditional. What is your go to methods while in the field?
Usually traditional method.
I saw you did shrink for the first offset, do you add shrink for the second offset as well?
Only if you're trying to reach a set point. (Like a box) But, more likely the pipe will end and you'll be using a coupling. So it wont matter.
4:08
But didn’t he had to add 1 1/2 in shrinkage instead of 3/4 ?
He did 30° bends and shrinkage for them is 1/4", obstruction is 3 inches, 3 times 1/4 is 3/4. So he lost 1 1/2 on the full stick because the two bends each lost 3/4 × 2 = 1 1/2

Excelente explicacion !!! Grafica !!!! Saludos desde argentina
Cheers from San Diego!
does it matter which bend you do first on the two inside bends?
No it doesn’t
Nope
You used the 30 degree bend correct? So shouldn’t the shrinkage be 3/16” per 1” and not 1/4” per 1”?
for 3/4 conduit 3/16 per inch is 22.5 degree, 1/4 per inch is 30 degree. it goes up 1/16 per inch starting with 15 degrees at 1/8 per inch
Hi Mr Bill, thanks for your lessons
No problem, thanks!
where you getting 7 1/4 from
The 7 1/4" was the width of the obstacle.
Is that 7 1/4 " from the outside of the first pvc to the outside of the second?
@@mikegranese5480 Yes.
Hey i like the video!!! but isnt that arrow on the bender that you were using for offsets only meant for 90° bends? I thought you were supposed to use the notch for offsets
The notch is for your middle bend if a 3 point saddle bend and that’s all it’s used for outer bends on a 3 point saddle use the arrow as well
Hi Steve. David Zee gave a perfect answer for you.
So you added the 1/4" shrinkage and 2.0 multiplier but did 30° bends . Am i wrong?
You are right. That is all correct info.
Does the multiplier or shrink change with different size of conduit? So if the multiplier for a 1/2 inch conduit is 6 will the multiplier for 3/4 inch also 6?
yes it will
Absolutely will.
Excellent work thank you.
Do you have a chart like in the 3point saddle bend video please?

Thank you sir
@@vincentsmith4328 No problem, thanks! 2 more EMT bending videos coming this weekend. :)
How did you get 7 1/4 from the the middle ? Thought it was 6 inches from center? Just curious
You have to add 1/4 inch for shrink for every inch of rise on that side.
It's the total measurement of the two pipes, edge to edge
Sparky We need u to keep making more of these Great videos.
That's the plan! Thanks!
Do these principles apply for bending rigid metal conduit?
Yes.
Very detailed educational videos , love it , God Bless Sir .
God Bless you as well!
Great video I need a tape measure like that
Thank you for sharing your knowledge Sir
My pleasure, thanks Shane!
@@SparkyChannel you bet. You're Videos are Awesome
How did you decide to come up 3”?
The pipes were 2 5/8" off the plywood and you need to leave a little clearance so 3" was good.
Similar to the shrink when you get into a pool.
LOL! Good clean joke. I like that!
Haha. Thanks for the videos, learning a lot watching them.
Boom ! Great vid Sparky !! Thanks
No problem, thanks!
I'm confused about the 7-1/4"
I was at first to. 7 1/4 is the called the travel witch is the distance from the two pipe ends
Length of obstruction
Where did you get the 7 and a quarter
That is the measurement of the obstacle (the pipes the saddle was going over)
Good answer Jack! Thanks!
Inside mark bend, outside mark bend *flip conduit around* inside mark bend, outside mark bend. Finished. And all from the ground (for better results) Try bending 45+degree offsets this way and you’ll find the plain of the pipe is directly in contact with the handle.
Yea especially if the conduit is going to be in an area that's super visible and always seen, 45 degrees are sharper and look nicer
Couldn’t you use the push through method so you don’t have to keep taking it out?
Yes, you can do it that way too.
Esa tabla aplica para tubería de toda pulgada?
Si solo te da la medidas de reducción y eso.
Awesome video Bill.
Thanks David! 👍
You are a life saver
Thanks!
how come you only have to account for shrinkage on the first A/B bend and not again on the C/D bend?
Hi David: I just made a video that should answer your question: EMT Shrinkage To Make 3 Point Saddle Bends: Save $$ by Knowing EMT Shrink Calculations: ua-cam.com/video/Xfsk74ffdpQ/v-deo.html
Because the conduit is gonna shrink 1 way not both
where i can buy that meter.i like that
Is 2 -30° bends to its shrinkage isc1/4" so u just add a 1/2" for shrinkage..im confused..

Glad you enjoyed it, thanks Matthew!
He only accounted for shrinkage from one side of the conduit. 3/4". HOWEVER the actual shrinkage is double that amount because you are doing twice as many bends. How do you account for that extra shrinkage?
He accounted for both sides. Around 5:10 he adds 1-1/4" to the 6" distance between offsets.
That shrinkage is at the end of the run
@@josephguida5432That was for the obstruction dummy. The two middle marks have NOTHING TO DO WITH the offsets. 😂😂😂
@@That90sShow It's on the 1st and 3rd mark. Review the video again, you'll see.
@@That90sShow What you obviously don't understand is that the shrinkage is added in 2 different bends, in 2 different places on the conduit.
I had an obstruction that was 2" high and 4.5" wide. A four point saddle wouldn't work right, the distance between bends would be too close right?
you could always just use smaller degree bends to put more space between the bends.
You rule Sparky
Can you upload a vid about 90° degree bends , I'm really having trouble with that and subtracting 5 or adding 5 , thanks
Yes, I'll try to make one not only on 90° bends but on back to back 90's.
It’s a lot trickier on a electrical bender like a 555.
Yeah way more spring back.
Do you add shrinkage on both sides or one side?
One side.

Cool channel sir u explain it well I’m gonna get that tape
Sounds good Juan!
Why 6” distance between bends?
The height needed is 3", multiplier of 2 for 30* bends. So 3" x 2 gives 6" between bends. If that makes any sense
30 degree triangle is a special triangle with adjacent = sqrt(3), opposite = 1, hypotenuse = 2. Scale that up to match the opposite (height) with 3" requires multiplying all sides by 3", so the hypotenuse becomes 6". Also the shrinkage factor is just (hypotenuse - adjacent)/opposite, or how much more length along the pipe compared to the horizontal length, all per unit height gained (it's actually like 0.267" per inch for 30 degrees). The steeper the bend the less accurate the triangle approximation works, since the bends have arc lengths that aren't actually at sharp angles.
