How To Bend EMT Conduit Into Circles! 

I finally updated the calculator to work for more than 4 segments. Here is a link for those interested ------> makerpipe.com/pages/incramental-bend-calculator

Exactly what I needed! Your the best, SIR!! Making an observatory dome out of a geodesic kids monkey bar set and need to fabricate a roller bar to suspend it on my base ring rollers. Went from not having a clue to a solid plan in mere minutes! THANK YOU!

You just saved my brain! ❤ I have been trying to bend perfect arches for our hoop house and failed multiple times because I couldn't get my calculations right! Thank you for this video! 🎉

That was simply outstanding. Thank you so much for this. You've saved lots of people time, materials, and curse words.

Thanks for this most helpful video.

Also…thanks so much for the calculator. So incredibly useful!!!!! 🌎☮️

Forever thankful that I found this video! I was just setting out to do all the math with a paper and pencil, to figure out how to bend a 10' pipe into a 36" diameter circle. My last math class was 30 years ago, lol.

Thank you so much for this. I am doing a huge project with complex half circle bends like this, and you are a lifesaver! Rock and roll man!

You my good man are officially my favorite person of THE WEEK!!! Thank you sooooo much for this video and calculator from a total math-a-phobe.

really appreciate your channel. I am building an internal frame for my canvas tent and your videos have given me the right information I needed to make better decisions on the build. Will also to go ahead and get the Klein bender instead of getting one of the no-name ones off Amazon. I can already see a lot of future projects for my overlanding setup. Possibilities are endless.

Thank you so much for creating this, it was super helpful! I ended up having to make two circles, one at 30 degree bends and one at 10 and they both turned out great! Thank you again!

Dude. Thank you. I want to do a gradual bend for a camera dolly and this is perfect. Also, I am so excited about the online store that you have. This opens up my mind to so many cool ideas. I’m excited to start working more with pipe as ideas arise.

I love this! I’m definitely going to use this

Thank you for the tool recommendation. I'm building a circle of 40 inch diameter. It will have teeth for a gearing system. Ideally it would be perfectly round, but this will be a kit for the general public. What do you think the most likely errors people will make so I can try and build compensations into the design? Out of round? Warped? Something else?

So helpful! Thank you!

Excellent video. I am looking at building a magnetic loop antenna for ham radio. A 36" diameter loop is needed for the main, large loop for the bands I want to tune to. So, your tutorial definitely gets me started. Thanks!

thanks, always wanted to learn that skill

I've found that building big hoops and wanting them perfect "like on an airboat cage." I'll lay the OD and D out on the shop floor in chalk to mimic what I want. Then I'll take 1/2" plywood and cut 3 pieces based on a 1/4 of the circular layout. Then take one piece and cut 3/8" for "3/4 emt" or 1/2" for "1" emt" off the radius. Then screw them together with the shorter piece in the middle "lining up the flat edges". Then I'll bend a piece of flatbar to fit around the emt I'm working with, leaving 3" tails beyond the emt, and screw it over one end of the jig using a drop piece of emt as a Guage fir fitment. When it's put together it looks like a quarter circle with a groove in the middle "for the emt to ride in" with a strap to lock emt into or (like a giant tubing bender). For airboat cages. I make two pieces and cut the 3" tail off then weld the butts together making perfect hoops for the prop cage every time. I have several of these for different diameters. It works great, try it

I need a few 1" EMT circles 10' in dia. I thought I was in the market for a Harbor Freight tubing roller. Apparently I don't as I've already a set of Step On benders. thanks.

Fantastic video and Tool thanks

I want to build a foot rail. I have a curved island, wondering how to calculate that? What kind of professional would do bending pipes? Electrictian?

Thanks for the app I wanted to make hoop house roofs and tomatoe trellis

"Circle Back To That", really... just really?😆 Great video, thank you for doing all the leg work!

Could you please tell me how to bend a 75 foot circle is it 1.5 degrees per 7.5"

Easy way to repeat bending the same angel Bend your first angel (10 degrees or any other angel.). Measure perpendicular with tape measure from floor to top of bender handle. Make each consecutive bend the same measurement floor to top of bender handle. All your bends will be the same

This is great. I'm trying to build a light fixture out of 3/8" brass tubing and was curious if this calc will work for 3/8" if not would you be willing to share the formula you use?

I want to bend 1/4" copper acr tubing into a circle. I know the demensions but where can I get a bender for such small stock?

Be sure to keep each bend on the same plane

Great video! Is there a way to join the conduit seamlessly...similar to extenders for pvc?

How would you bend pipe into an ellipse? I imagine the angle changes as you progress along the pipe

I would like to get the App you use to calculate a bend, where can I get it?

How would you recommend connecting two circles together like an “8” pattern

Fantastic. Could the connectors at the segments somehow allow for adjusting a bolt to expand or shrink the diameter? I'm thinking of ways of securing a ring/strap around a 30 gallon bucket and would like to adjust the diameter a bit to allow for securing and releasing the grip on the drum

Great video. If I want make arches will this calculator work if I choose 2 sections?

Fantastic video and very helpful. I'm making a hoop house/high tunnel (but not that high) for the garden. Need to cover 2 rows of crops. Two sticks of 3/4 EMT (20 feet) will make it too wide or too tall. Is there a way to calculate for say 17 feet of EMT, ie 2 sticks at 7 1/2' each? Thank you!

This is fantastic and exactly what I was looking for! Thank you for posting! I'm actually looking to make a 344" ring for a cyclorama. Any recommendations on the number of bends/distance between bends for a circle of that size? I know I'm looking at ten 10' pipes, but that's about as far as i go before my math is tapped out.

Nice. Is the calculator for 3/4 only?

THANK YOU!!!! Question for you though - I'm looking to make a large U shape...on the order of 16' wide (192 inches from end to end. The calculator says it's 6 sections, but I'm not clear on the segments. I only need 1 U shape, and this appears to be designed for bending a circle. If I adjust this to 2 segments, would I then only need 1/2 the number of conduit sticks the calculator states?

Thank you, now I don’t have to borrow my son’s geometry book!

I need to do a bend a this for a 100 ft diameter tank battery.

Awesome video. Thank you for sharing your knowledge. Bret / AC0AE

I need a 9 ft raidis circle help please

Hi. Will you mind send me the link for the bend calculator? Cant find it below you video, please.

@makerpipe (Jake Lewis) I'm trying to bend a complete circle with a 15.5' diameter (186"), and 8 segments (I think they come out to roughly 6' per segment), but I can't get the calculator to work for this, can you help? I'd bend at 10 degrees to keep things smooth. Thanks!

Is this sold in the UK as it might be something of interest for some projects I have lined up.

I ended up with a octagon

Angle!!! I meant ANGLE!!!

Actually, I think you should have shown the math, so that people can understand it, if they want to learn how you figured out your segment spacing for a 10° bend at each marking. Here's how I reverse engineered your math: A half circle is 180° & since you made 18 bends, that is where you came up with the 10° per bend (i.e. 10° per pend * 18 bends = 180°). A 3 ft outside diameter circle would have a circumference of C/3=pi or C=pi*3 or ~9.4248 ft length (so you could have used a 10' piece of conduit for one continuous circle). Since a full circle is 360°, if you divide that by ~9.4248 ft, you get ~38.197° per foot. If you want 10° bends then you take ~38.197° per foot & divide by 10° to get ~3.8197 segments per foot. Then you take 12"/ ~3.8197 segments per ft = pi (i.e. 3.14" long segments markings--which is the length that you used between your markings).

😅🤭😑

can you go over the math, without using the calculator

But not 100%
