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
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! 🎉
You're very welcome! I am glad that you found it helpful. Thanks for the comment!
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.
Haha I feel that. I recorded this video twice. The first time I explained the formula and realized no one wants to watch me teach a math lesson. Then I made the calculator and second video lol
That was simply outstanding. Thank you so much for this. You've saved lots of people time, materials, and curse words.
I’m glad it’s helpful! Thanks for watching and commenting Diane.
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.
Awesome to hear that you find the videos helpful! Sounds like you've got some cool projects. Let us know if you have any questions as you're planning/building down the road. Thanks for the comment!
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!
Awesome, I am glad that you found it helpful! Thanks for the comment
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.
Glad you like the video and website! Let us know if you have any questions. P.S. I'd love to see your camera dolly!
Also…thanks so much for the calculator.
So incredibly useful!!!!! 🌎☮️
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
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!
That's really awesome to hear! I'm glad that this was helpful! Thanks for the comment
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?
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.
Nice! I’m glad I could be of help! Thanks for the comment.
Thanks for this most helpful video.
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.
Nice, glad you found it helpful. Thanks for the comment!
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 for the comment and good luck with your project!
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?
I love this! I’m definitely going to use this
Awesome! Can’t wait to see your builds! Thanks for the comment
Could you please tell me how to bend a 75 foot circle is it 1.5 degrees per 7.5"
So helpful! Thank you!
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?
thanks, always wanted to learn that skill
Happy to help. Thanks for the comment!
"Circle Back To That", really... just really?😆
Great video, thank you for doing all the leg work!
Haha just be glad I forgot the other ones I thought of before filming 🙈 happy to help! I don’t want bending circles to be your ARCH nemesis lol
Be sure to keep each bend on the same plane
That's a good tip! Thanks Jim
I would like to get the App you use to calculate a bend, where can I get it?
It's on our website here. makerpipe.com/pages/incramental-bend-calculator
Thanks for the app I wanted to make hoop house roofs and tomatoe trellis
You're welcome. Glad you found it helpful for your projects!
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?
Sorry for the delay in getting back to you. I don't see why it wouldn't but I am not 100% sure tbh. Have you attempted the bend yet?
Great video! Is there a way to join the conduit seamlessly...similar to extenders for pvc?
Thanks Elaine! You can use no lip threaded pipe inserts with a bolt between the two
Fantastic video and Tool thanks
Thanks so much Galen!
How would you bend pipe into an ellipse? I imagine the angle changes as you progress along the pipe
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
That's a cool idea! You might could use the Maker Pipe Coupling and Quick Clamp combination to achieve this. It might be kind of tricky though because bent conduit arches tends to fight back when trying to align and couple them together perfectly.
How would you recommend connecting two circles together like an “8” pattern
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!
Hi there, glad you found it helpful. How wide are the two rows of crops?
@@MakerPipe Yeah, it's kinda a weird bend, at least for me. The 2 rows of crops are 30" each with a 12-14" path between. So I need 7' diameter. But I want the first bend to start at 3' using 2 sticks and then joining them with the MP connectors I recently ordered. I also don't want the top of hoop to be more than 6 feet so it doesn't block my neighbor's light over the fence. Does that make sense? Thank you for your time.
Great video. If I want make arches will this calculator work if I choose 2 sections?
i would assume ye
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?
Hey Don, great question! Basically we are limited to 120" per segment because thats the longest off the shelf stick of conduit we can buy. So in your case you would still want to calculate for 6 segments of a circle because that comes out to 100.5" per segment. However instead of bending 6 segments into a complete circle you will just need to do 3 to get half of a circle or the U shape you're after. Unfortunately the calculator can't figure out any more than 4 segments but I can do the math and let you know the measurements. What angle would you like to bend to each time?
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.
Thanks for the comment! Glad you liked it. I am currently working on updating the calculator to work for any size etc. I should be finished in the next couple of days and will report back.
Here is the updated calculator! makerpipe.com/pages/incramental-bend-calculator
Hi. Will you mind send me the link for the bend calculator? Cant find it below you video, please.
Yes, here you go. makerpipe.com/pages/incramental-bend-calculator
@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!
Hi sorry for the delay in getting back to you. After doing the math, I think you'll need 585" in total conduit. Each segment is 73.125" and you'll bend 10 degrees every 16.25".
The formula is radius 2 times pi times radius. That tells us how much conduit is needed. Then you divide that number by the number of segments you want to find out the lengths of each segment. In your case you're bending eight 45 degree segments with incremental 10 degree bends so you'll divide 45 by 10 to get 4.5. Then divide the segment length by that number to get the distance between each incremental bend. Hope this helps.
Nice. Is the calculator for 3/4 only?
I'm pretty sure it will translate to 1/2" and 1" as well but I haven't tried it so I'm not 100% sure. I'll see if I can work through some math on it and follow up.
@@MakerPipe Did you find out if it works for 1/2” yet? I’m very interested in doing this, ordered a few items from you already. For my project 1/2” is not only less expensive, but it would otherwise be overkill if I used 3/4” THANKS
@@lindseyoldani3557 yes it works.
Thanks man. I’m doing this today and honestly that 10 degree bend is difficult to not surpass, I got my bender used and the stopper is gone. I’m making hoops though so there’s that
Is this sold in the UK as it might be something of interest for some projects I have lined up.
We are able to ship to the UK but the main issue is pipe. Our connectors fit .922" and 1.163". There hasn't seemed to be a comparable size that would work over there. Do you know of any?
@@MakerPipe It might do for copper pipe. We have similar sizes which are near 3cms for the 1.163". It might work. Aluminum pipe could also work if the diameter is below 2.9cms which most EMT pipe is 20mm or 2cms in diameter. SO it could work on both items described.
I need to do a bend a this for a 100 ft diameter tank battery.
Woah that's a big one haha Have you attempted it yet?
Thank you, now I don’t have to borrow my son’s geometry book!
Happy to help!
Awesome video. Thank you for sharing your knowledge. Bret / AC0AE
Glad you enjoyed it! Thanks for the comment!
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).
I ended up with a octagon
Uh oh. Did you bend each time at 10 degrees?
Angle!!! I meant ANGLE!!!
😅🤭😑
can you go over the math, without using the calculator
0:10 Clearly stated he’s Not trying to make a math video. Maybe go to your local school and ask a math teacher.
Who pissed in ur cereal
Length of conduit = pi * diameter of final bend. So a 36” diameter full circle = 36” x 3.14128 = 113.097”
Degrees per bend = Total bend in degrees divided by number of segments, so a full circle (360°) done using 10 segments requires 36° per segment.
Length per bend = length of conduit divided by number of segments. So, for full circle in this example, each 36° bend will be about 11 inches long.
But not 100%
