That's amazing. I see a lot of people make tubing benders, but this is the first time I've seen a die build that made me think "OK, that works for a home shop". Even if you had to re-print the inner part once a year, it would still be awesome.
Where did you get the STL and the Plasma file from?
This is great! More and more people are discovering that 3D printed plastic can be used in a lot of high-force applications. As long as the plastic is well-supported, it can handle amazingly high loads. Others have made dies for press-forming sheet metal with excellent results. I think this is the next frontier for DIY metal fabrication tools.
PD: it’d be great to see a build video for the tubing bender itself!
Had 3d printers since 2014.
Been looking for a good, cheap tubing bender for almost as long as a DIYer.
REALLY glad I found your channel today!
I am already printing cores and will make the metal parts at work this week.
Thanks!!!
Howd it go?
Will the plans for the tube bender also be available for sale?
What a great idea! I don't have access to a plasma cutter, but I do have a angle grinder and a bench drill + a 3D printer, and I mostly print using PETG. I did not think PETG would be strong enough for this usage, this surprised me ☺️
I need a bender for 1inch / 25mm diameter pipes having 16gauge / 1.5mm wall thickness. I'll just have to try a 3D printed version now 😁
Thanks a lot for a great video!
Doing the lords work sir! I’m so excited to buy your plans for this!
I have seen videos of printed gears replacing metal gears in a lathe and they were quite resilient. Amazing you can make a bender dye using 3D printed components.👍
Excellent, clever use of 3D printing.
Awesome video and an amazing idea using the 3d printed parts. I would to be able to buy the files and even the plans for the bender if you have them. Great job on the video, thanks
Very impressive! I'm surprised with how perfect that it turned out. Thank you for sharing that!
Nice looking dies and bender. Thanks for the interesting video.
Good work on this die. We shared this video on our homemade tools forum this week 😎
That’s just awesome I would love one of those dies
Love your ingenuity JD! Was surprised to see using a 3D printed part as a component.
You guys are awesome! I hope you break the internet!
Awesome. as soon as your plans become availible id love to have them.
Very clever guys…I had a JD2 bender and apparently the dies are machined with slight flats on the side to support the tube where it usually likes to deform, results were true round tube after bending, by printing your own this would also be achievable. Either way…great result. Cheers from Australia
Awesome! Did you design and build the bender mechanism also? Would love to build one.
Very cool pipe bender. Love the 3D printed die.
Brilliant. Thankyou fur sharing that hard won knowledge
Absolutely awesome work sir.
I modified a Harbor Freight “pipe kinker” die and I can bend .120” wall 1.75” DOM without issues. No waves, no kinks, no cracks. I also modified the other die to bend 1.625” (1-5/8) .134” wall. They all work! Make sure to use lots of oil while bending.
More info on your mods please?
en argentina tienen harbor freight?
@@beno.- no se. Pero si buscas “Harbor Freight pipe bender” vas a tener una idea de cómo es y probablemente encuentres algo similar por ahí. No es una herramienta muy sofisticada y se puede hacer una usando un gato hidráulico.
Nice build!
Really great idea! I have made drawings of a similar construction. But I was thinking of using oak. This is a better idea.
Awesome ! Thanks for Sharing.
PETG is more than enough for thin wall tubing. Nice work guys
Wow! I never thought that the plastic would be strong enough so that it doesn't deform. I was thinking about casting aluminum dies but this is way simpler.
Wow! I never thought that the plastic would be strong enough???
Depends on what you want to bend. JD's even says it can't bend seamless DOM tube. Lots of people use ERW or electrically welded tube, it has a seam inside and is MUCH more easy to bend because it is MUCH less strong.
I need to bend both. So I only use steel or aluminum dies. I build dune buggies and race cars and would use both DOM and ERW. But in any high speed use such as racing or a roll cage that your life could depend on what do you want to do? ERW or DOM?
On a kids dune buggy that goes 20 mph ERW is fine but I probably would still make the main roll cage hoop out of DOM then use ERW for the rest. If your building a small buggy that will use a 90 hp snowmobile motor and will go 100 mph then come apart and kill you when it rolls and flies end over end, you going to build that with ERW? Not me, I am going to use DOM tube.
Then there is 4130 chrome molly tube. Super strong, super expensive and hard as hell to bend. Best race cars are built with it specially in the EU.
So these plastic fantastic dies don't actually seem so whiz bang great after you think about it. At least not to me. Build cheap dies? I would find some 1/2 aluminum plate sandwich it together with steel outer plates then use a home made fly cutter to do the profile I wanted such as 1.5 or 1.75. But I am a machinist so I can do that. I also save up $$ and then buy good steel dies but find used ones.
Decently good aluminum dies are easily available even used on ebay. I have used them to build a simple bender that did struggle but could bend DOM tube. While bending the DOM tube the aluminum die had no problems, my 8 ton jack did though. Should have used a 20 ton air/hydraulic jack.
Build a good bender with strong dies. Then if you need to pay for it rent it out. Or charge by the bend. After I built my first bender and word got out, I had lots of new friends who needed to bend tube, everything from exhaust tube to DOM tube. I said bring the beer and your tube and lets do it. Thinking back I should have charge them $$ not beer but oh well. They all still owe me favors now. Racing is like that, more people you know the more you can get done for cheap.
You are the MAN!! Thank you
Thanks Great ideas and video
Awesome work on the tube bender design and build. Those look like stainless steel bolts on that 1-1/2" die. You need to go to steel bolts. They are almost twice as strong as stainless.
I was a tool and die maker for years. We used bacon grease to hand tap and to cut threads on the lathe. Give it a try.
Man I love this video but unless someone has a 3D printer and that material and even the plasma cutter, they're NOT making this under $10.
I still think that's an incredible use of a 3D printer, but this is not repeatable by 99% of DIY'ers.
I'm still giving your video a thumbs up because it's still awesome.
Just a heads up, most public libraries have 3d printers available for public use
Man, that turned out great. Do you have a video, or plans on the plastic part of the die?
Did you design this bender yourself too? Looks simple to construct. If so I'd definitely be interested in plans.
Really amazing project, I have never seen or thought of printing a die. Just one helpful suggestion from an old retired structural engineer, all bolts are designed to stretch, however under proper specified torque. Look up the torque specs for the bolt size and grade instead of using an impact. The impact may have yielded the bolts, or not have tightened them enough. In all honesty, those bolts may have been a little small and of lower quality. That would have been the cause of your die opening up when bending thicker walled tube. Love your video, subscribed. Cheers from Canada.
Great video. Didnt know that petg could whitstand that force.
2 JD garage.
Best videos I've ever seen on TH-cam on building crosscart. Thank you for these videos and information on how to.. I deeply appreciate that and also all the research that you do share to the TH-cam Community and specially to me. Question where did you get that tubing Bender with the hydraulics did you build it or did you purchase it. if you have any information on the tubing Bender machine can you please share that with me I would like to find out where I can pick one up at just like that. God bless to you your family and all your friends thank you sincerely Walt. God bless brother.
We built the tube bender, more information about it will be available in a future video.
Surely as you go up in diameter of tubing and strength, the gauge of the side metal should be thicker to cope with the extra force, plus thicker/stronger bolts too.
Very interesting. Hadn't considered that fabrication method.
Great job. Impressive. Please can you share details about the bending machine itself? Did you buy it or make it? If it's bought, where from and what specs? Thanks!
JD you could use steal inserts for your bolt holes then you could torque the bolts but awesome build.
Awesome Buddy
in reference to the 3D printed centers... what was the % of infill and # of permitters. Is there a specific infill pattern that works better than others?
Super awesome and smart thinking, but as you pointed out the person who did the setup for the 3d printing knows there stuff an most people would have no clue the settings or correct code to use. I brought my 3d printer off a tool making an the things he could do/make compared to what i can do/understand as a novice (he even gave me some test prints an the files but i can't get them anywhere close to the standard he could do)
Thanks for an awesome upload :)
Do you make the die radius same as the OD of the tube? Or a slight ellipse ?
Very clever, i have a baleigh 125, are there any plans available to make dies for these. I have a plasma cutter but no experience with 3d printers
awsome tools...6 one way half dozen the other,,,,they could use scafolding and dual elevators for air cargo...if you look you might make some money....we could alll use some of that...if not can always make toys....happy holidays...
I built that bender a couple years back from the gottrikes plans. Can you tell us what 3D printer works best for printing those die cores?
Wow, hanks for the idea. I have a bender but figured out lately the dies would cost almost as much as the bender did, but now, thanks to you, I have a solution!
Is the center part printed solid? Or what infill rate and geometry?
JD, would there be any benefit to a) alternate the sides every other bolt so the heads are opposite to counter any stretch of the bolt? snd b) gluing/epoxy the two halves and the steel together to solve the DOM issue longterm?
I am impressed that this works. Thanks for sharing. DOM is desireable because it is so much stronger, so it is understandable that it is harder to bend.
But, there are more than 10 dollars worth of bolts, probably more than 10 dollars worth of PETG, and a few dollars worth of steel plate. And then you reused parts from the old die. Clearly an inexpensive die, maybe $30-$40, but not $10.
Suggestion: Go to a pawn shop and buy dedicated end wrenches for your bender. Then weld on some hooks to hang all the tools needed for the bender right on the bender.
I thought DOM was a manufacturing technique that could be used with a variety of alloys
@@neffkI suppose it can, but when someone uses the word DOM in the USA in fabrication circles it refers to steel tubing.
I have been a fabricator and welder since 1967, and have never heard the term describe anything else.
Next time you are in a steel supply place, ask to see DOM and see what they show you.
Now you should look into dimple dies and metal brakes made from 3d prints. I'm glad I found this channel lots of good ideas and I think you folks are close to me in ND.
A CNC Plasma cutter kid nice, but far from necessary. If you feel a CNC cut part is important, sub it out. This piece can be made entirely by hand, it may take a little more time.
@@paulkotowski4006 Its all about efficiency and repeatability. If you are doing a 1 off sure but if you have to make 5 of something this saves you time. I run a router CNC, CO2 laser and 3d printers I can make parts to sell and tools for my shop at the same time.
Any ideas on a mandrel? I'd like to build a machine to do 3/4" x .062 square mandrel bends.
Do use specific manufacturers for you filament choice or any quality filament?
How much would you charge me to plasma cut plates & print cores for a die that takes 1" tube at a 3" radius? I can handle the drilling & tapping.
Excelente!!!
Any word on when this design will be released? Almost time for a new winter project. 😉
Would your 3D printed system work for making a 2" OD die?
How do you determine what the radius is on the bend? Like, how aggressive can you get?
This is awesome. Is the file for the core available for download or sharable? I'd love to build a 1" and 1.25"
Currently it is not but it will be soon.
This is great! when were you hoping to have the files up for sale for these? I have all the tools to make these and would love to test them out
In about a month or so they will be available.
@@jdsgarage701 Any luck getting these die plans on the product page for sale yet?
I’d be interested in purchasing the plans and print file as well. Have all the tools to do this just horrible at the computer design
For those without a 3D printer do you think someone could use two sheets of 1/2" plastic and router it out with a 1" concave bit? For the plastic was thinking HDPE. But would HDPE be too soft?
this would be a use for aluminum casting using the plastic as a plug..
Nice job! I would never expect PETG die to work.
What is the model of a bending machine you are using? I like it since it bends vertically, it is easier to measure the angle.
It's a homemade bender.
Hello im very interested in your process did you build the 3 d printer ? if so are you open to help people one ?
Hi, I want to build a 180 degree, 1-1/4 sch 40 pipe die. A couple questions: are the outside steel sides the same on all dies for the model 32 bender? Can you build the plastic 3d parts for me, and what would it cost? Thanks.
Nice!!!
Brilliant! How much for a 2.375 die? Just want to bend chainlink fence posts.
When are the plans and dies going to be available?
I did hear about 3D printing sheet metal press. But Bending machines with 3D printing blows my mind
This is brilliant. I’ve purchased your plasma cutter plans, will you be selling the files for the various size of dies?
We've got a bit more testing to do but eventually yes.
YES! 👍😎👍
Would you be able or willing to share or sell the layout of the the frames of the GoCart Frames that you built with your dies? We would like to try to build something like that for our son, we just cant afford to purchase a Turnkey Unit.
do you have any plans to sell any of the dies if so do you know when
Plastic! 180 degrees too. Never would have believed it.
An improvement would be to run sleeves so that the bolts can be preloaded. That would make stretching less likely.
Do you sell the 3 d printed section I need 2 different sizes 1in and 1.25in I can make the outside plates just need the center part and how much thanks love all of your videos
Currently we do not sell them, but are working on logistics to make it possible.
@@jdsgarage701 can you let me know when you get them ready and how much thanks.
I have an Ultimaker 3 Extended 3d printer. The build plate is about 8.5”x8.5”. Is that large enough to print that die core? Also, if a larger radius die was needed (larger than the printer’s build plate), what are your thoughts about printing the core in multiple parts?
It would be a tight fit since the dies are 9" in diameter, it would still probably work if you split the core into multiple pieces.
What bender is that?
Also do you have the CAD/plans for these dies? Or the F3d file available?
It's a home made bender that we made a while back. The files are currently not available.
When you cut that out I could see what needs to be done to build your own die. Just cut the next one one eighth small then the next one a eighth smaller and so on till you get half the demetion you need then cut Sam different size for the other side bolt them all together and a little grinding and there you have built your own die.
Sorry if it’s already been asked but what makes bending 1-1/2 0.120 questionable? (In the link for purchasing plans)
Why didn't the CNC plasma cutter thread the 1/4 20 holes while it was at it?
Dude, i freaking LOVE printing with PETG and i actually need to build a bending die for a 1/4" aluminium rods...
Do you have plans/files available for the bender and these dies please. Great video 👍🏼
Not currently but they will be soon.
Seems to me that installing bushings around the bolts would let you really tighten the bolts without deforming the plastic.
Relatively cheap upgrade and could be just as easily be made from some tube
great video.is there a reason why u didnt make the 3d printed part one peice instead of two.thanks
Overhand angles are too large to print it in a single piece.
Is there no deformation in the central part ?
Thank you for the great video, have you thought or tried to build a die for square tube?
It will be in the next video regarding the dies.
This is great guys! I have the same bender and I've been looking at the KJ Cross cart builds. Can you tell me what 3D printer you're using? I'll be looking to purchase one soon!
We are using a lulzbot Taz workhorse and an ender 3. Both have had extensive modifications.
When you say you have extensive mods to the printers, does this mean it's probably not something that can be done as practice while learning 3d printing. That being said can these be made with a fairly basic printer? What's your preferred platform? Awesome job, I'm a fab/welder but still do it all the hard way...lol which isn't neither bad or good right haha! keep it I'm definitely subscribed!
@@squatchusmc9133 Most of the mods are fairly simple to carry out. We would recommend starting off with and ender 3. They are pretty much plug and play and cost $100 when on sale.
Great idea, was wandering if the 3D printed part would be available to buy ?
The printed cores are not available. The files to make your own will be soon.
What's your infill percentage?
Cool
What did you use for a follower?
Would it be possible to get the dimensions of your bender and for the die also? I would like to build my own. I am willing to pay you I need dimensions only.thank you much Jim
PS love you're channel
Send an email to the channel, in video description.
Thanks for sharing your experience and expertise. Are you planning on selling the dxf files for the dies and 3d printer files for a nominal fee on your website?
We've got a bit more testing to do but eventually yes.
Can't wait until you release them. I already bought the plasma cutter plans. Keep up the great work! 👍😎
Couple of things. Where do purchase your 1/4 plate? That is more than $10 US ea plus the material for the print. Plus fasteners. I'd say closer to $40 but still pretty cool as long as you had a plasma table and a 3d printer and know cad. Not like it is in everyone's garage yet.
Next, do you have to drop the follower out every time to remove the bent material from the bender? If so that would be a nuisance.
If you purchase the steel at a reliable steel supplier it is much cheaper. Around $6-$7/sqft for 1/4" both plates fit onto 1sqft of material. The die uses around 300g of PETg which goes for around $15/kg. You don't have to remove the follower, it makes it easier to remove the tube when you make large bends.
Para tubo de 40 y de 60 funciona?
Hi real nice never thought about building a die like this are you going to sell any if so how much for 1- 1-1/4 - 1-1/2 -1-3/4 thanks
Currently we do not but we may in the future.
does your 20 dollar kit plans include all dies up to 2 inches?
Let me just grab my 3D printer here.
I was excited till I saw that part.
