Bending of 1.5" OD 0.125" wall 6061 T6511 aluminum tubing on a JD2 Model 4 tubing bender with electric over hydraulic setup. This bending was done post annealing as shown in a previous video.
excellent work. i have given up on getting outside dime correct with one piece two bends. always end up making separate pieces and cut and weld the pieces at correct dimes. the bubble in tube is genius! funny how i can eyeball plane and lay it on the floor and be so far off. white lithium my friend also.
Man a saw your video thats cool I wish I had a bender like that,,,im so lazy I bet if I had a bender i be too lazy to usen it... Man you are a Boss!!!! cool video thks
Great job on bending the aluminum! 6063 bends much easier than 6061 btw. If you are trying to repeat and make the same part over and over, setup a stop and "bump" the ram the same number of times on each bend as well as each time you retract the ram. Every time you load and unload the material, you relieve tension which will cause a different final angle when going to the 94 to 94.5 degree. One way to eliminate this in between ram retracts is to run the ram until it stops, then retract. This will ensure you apply the same tension to each bend prior to retracting the ram. If you do a lot of the aluminum 90's you can drill a hole into the base plate and insert a pin or bolt or the like where you would want the bend to stop. You can have it hit the lower bend arm without interfering with the bend process. The table has a ton of room so you can put a lot of stops at different angles. If you make the stop stout enough you can run the bend arm into it without "bumping, thus ensuring repeatably. Keep up the great work!
Based on JD2's claim on their website "The Model 3 is the best selling USA made bender in the world", www.jd2.com/p-38-model-32-bender-hydraulic.aspx. Don't get me wrong, I think the Model 4 is fantastic, the Model 3 and Model 32 are more common for folks building roll cages. The dies are the same, the benders just are basically reversed.
i have this bender made my own roll around base . bend mostly raft frames 1in emt 30 mm die 1 1/4 emt 1 1/2 die 4.5 radius looking to buy dies for alum similar.
I'm getting ready to bend some 1 1/4" and 1 1/2" 1/8" wall 6061-T6511. I have a model 53 JD2 bender and two things I did prior to a 90 test bend on 1 1/4" x 1/8" wall was I chamfered the back edge of the follower die and I used axle grease on the follower die. I bent a perfect 90 degree bend without annealing the aluminum, no scratching, cracking or any evidence of failure so I think that the lube having high pressure characteristics is the key.
Hello: Get a copy of Manufacturing Engineering and Technology or Manufacturing Processes for Engineering Materials by Serope Kalpakjian. This will help you understand your bending issues with all materials. Also, there are charts that will help you after annealing the AL to get the bending prosperities you needed, then to heat treat after bending to get your AL6061-T6511 properties back. Also, there are additional bending trick, like filling the tbg with sand or a long chain of washers spaced apart by about the wall thickness of what ever you are bending. These methods are used to make sure that the tbg maintains its shape with out wall collapse. Good luck David Bradley (Mechanical Engineer)
I have a job where I need to build some railing for the back or a boat and I actually have another guy that wants 12 boats built...do you prefab and send stuff out?
Sorry for the delayed response, my youtube game has been weak recently. We can definitely do some pre-fab and ship but it might get expensive shipping bent tubing.
4.5", I only have 1 radius die for each of the tubing diameters I have dies for which is a factor I have to design around. The dies are pricey though, and usually the compromise on the radius I have available doesn't hurt the overall design of what I'm working on.
Depends on what your using it for and how many you need to bend. It is easy to find 6061-T6 or 6061-T6511 and those are easily welded. Most 7000 series stuff isn't weldable but is slightly stronger. My buddy imports 7005 from Taiwan in 0 heat treatment (and prays it isn't too age hardened) and that stuff bends like butter and is weldable.

Thanks dude. I just bought a No Dog because of you. Great tip. Thanks. And I love your can do attitude and determination.
Such a simple little tool but saves a lot of frustration when you are bending a tube multiple times!
good stuff
Man a saw your video thats cool I wish I had a bender like that,,,im so lazy I bet if I had a bender i be too lazy to usen it...
Man you are a Boss!!!! cool video thks
Keep the great videos coming thank you for the info

That's what i need JD2M4,Thumbs up
I think the Model 4 is their least popular model, but it fit my needs better than the other models.
why do you say it's the least favorite model? I'm in the market for a bender and i'm looking at the model 4. thanks

Dude is awesome, what an inspiration

My understanding is age hardening is also a big issue.
GREAT JOB MAN, GOD BLESS YA
awsome vid!
Pretty cool man!

Can you please share were you bought the little tube level ?

What radius die are you using? Nice work btw!
4.5", I only have 1 radius die for each of the tubing diameters I have dies for which is a factor I have to design around. The dies are pricey though, and usually the compromise on the radius I have available doesn't hurt the overall design of what I'm working on.
I have a model 32 and am hoping to use it to bend 1.5 '' aluminum tubing but not sure what type to buy
