Homemade Press Brake

- This is a homemade finger press brake. It will be powered by two 20 ton air operated bottle jacks. It has a bend length of 62 inches. I will be used to make lids and hatches along with other random bends.
That brake press is killer. I love that design.
Great job
Really nice size brake. I want to weld up a brake but I'm not sure how wide to make it. I don't have much space so getting the size right is pretty important.
For the top, adding a "spine" on it will help. That should bend 1/8" steel to 90° easy. I'd guess you'd need 2 20 ton jacks. Also, have an update video on this?
Looks great. But to answer your questionif the top 6x4 beam will bend, it will. I built a brake almost identical to yours about ten years ago. Worked fine on 14 gage material but bent the top on a piece of 10 gage by about 40 I inches long . Weld the truss assembly on top before you try anything real heavy. Great job though!
Ron what size jack did you use for 14g..I want to build an 8ft for sheetmetal.
Using two 12 ton bottle jacks
@@rontucci3552 how long was the 14g piece of metal?
60 inches
you mention a online calculator, have a link ?
Hey, I just stumbled onto your videos because I was thinking about building a boat like you are, and really liked your work. I am sorry to hear about your injury and hope your healing process if going well. So you can continue to do what you love.
Alex Grulkowski . Thanks. so far I get along with very minor issues.
Not a problem, and I also thought it was pretty cool that you live in the cities, I am a few hours away in Wisconsin.
I'm going to Midway and sending my friends there too.
Instead of just using Midway as a quote source you could give them your business since your supplier was giving it to you! "Discount" seams like they've earned losing some business.
Wow that’s a cool monster 👍
I don't see any other videos on this? Just the demo. Really interested in building this.
im a boat builder too. pretty much the same as you ive built 4 hulls from scratch without a brake. i love yours. where did you get the finger dies for this build? it would be awesome to have something like this that doesnt take up much space but can brake .125 5052 for furniture and lids.
how is your arm doing? you should make an update video on the boat and your arm
Nice work!
what was the online calulator you mentioned please? great build by the way
Like your shop! Where did you get the fingers for your break witch looks awesome.
I machined them on my mill. Made a jig that held at 60 degrees and machined both sides
Amazing job! Better than the crap they sell in stores. Where did you get the bending blades? Sorry I don't know what they're called.
R.C. Welding's garage . Thank you. I machined the dies myself
@@TheJessehart05 That's some quality work there.
You’ve gotta worry more about deflecting the bottom beam, also don’t know if you have a crown on the bottom plate, all brakes have crowns for deflection.
Do you know approx. how much of a crown needed for a 30" wide brake? Thanks
@@donsmith9081 I think I would just buy a 4 or 8 ton bottle jack and rig it up too the middle of the bed, a lot of brakes I’ve operated had hydraulic cylinders, longer brakes had 2, all you’d have to do is put 1 jack in the Center, and use it when you’re doing heavier material. I wouldn’t worry about a crown on such a small brake, use the bottle jack.
Also what material are you bending and thickness. ? I’m a 100% sure that idea i posted will be your best bet.

@@duramax78 I appreciate your replies. I have a 50 ton Ramco press. I would like to bend mild steel 1/4" 30" long.
@@donsmith9081 thank you, I’ve ran anywhere from 80 ton to 750 ton brakes and presses for many years, you’re getting fairly thick for a machine like that. Is it manually powered or powered? You should maybe look for some old dies made for a bigger brake, if you can find one area of a 18’ or whatever die your length that is in good shape you can always cut it down, there’s lotsa damaged dies with good pieces. And also do you know the 7:1 rule in braking? What kinda radius are you looking for.? You should be looking for about a 2” bottom.
Sweet build! Been wanting to build one for a while now. Getting tired of clamping my plates to a piece of W24 I-beam and hammering the angles I need. Where did you get the top dies from?
MAJOR OVERKILL . I made them on a mill.
Beautiful work
Nice build! How thick of plate did you use for your press break teeth/dies?
Yo bro... question how thick is the die? Or what dimmensions is it? Need to order some 1018 CR Steel for my break project. Thanks in advance?
Eric E. Vera I believe the die was 1” thick by 3”wide
How did the press do?
What calculator online did you use?
Where did you get the finger press brake part with the dies? Hope the injury is healing well. I want to see more of your big boat! Awesome work. Looking forward to more videos in the future of how you're doing hatches, etc.
Noah Lochner . I made the fingers on my mill. 60 degree angle.
+TheJessehart05 badass! How’s the hand doing? Any progress on the boat?
Where did you order the finger dies from? Currently building an 8ft brake and was wondering where u got yours thanks!
I machined them out of cold rolled 1018 steel. Good luck with your build
TheJessehart05 Awesome! Very talented thank you for sharing your build
Hey Men that's exactly what I want to build, but I need at least 2 meters long. So do you think it's possible? May be using two jacks? And I need to bend 1.5 mm thicknesses but 2 meters long.
alvarenga512 . Yes, I have 2 20 ton Jack's that bend full length of 1/8 aluminum like it's nothing. PM me and I can send you finished pictures.
Thanks a lot! But where can I send you a PM? I already add you in my google account
alvarenga512 . Email me. jessehart05@gmail.com
Very nice work. Where did you get the fingers?
Rocky Blankenship I made them on my milling machine
@@TheJessehart05 Even better! Great work.
Jesse ,
Did you make or buy the fingers for this brake ?
Daniel Lance I made them out of 1018 cold rolled steel
@@TheJessehart05 Thanks for the response Jesse . I apologize because right after I sent you that message I read through another comment where you answered that detail . My bad ! That's a nice brake . I have a pair of 50 ton air assisted hydraulic jack's that I'm going to use to build a 10 foot wide brake . I am primarily going to use it for aluminum but might occasionally bend some steel or stainless steel and am concerned that mild steel fingers will deform .
Daniel Lance No problem. Good luck with your build.
You should just buy a used electric log splitter and use the hydraulics.
What's the calculator on the Internet that you used
Garrett Caryl . Just Google press brake tonnage calculators
Did you sell that brake?
Randal Nannie yes
how did the bends turn out? anything you would change?
Bends turned out awesome. I wish it was bigger and I'm going to make an adjustable back stop.
@@TheJessehart05 What do you mean Adjustable back stop?
Rocky Blankenship something so you could slide a piece of metal in and it would stop so you could have repeatable bends without measuring
@@TheJessehart05 Nice build. Researching how to build an adjustable bottom die.
Rocky Blankenship don’t over do it. Keep it simple. Make two different dies if you need to. Good luck with your build.
Any new vids of the press working or done
I can make one for you. Give me some time to get to it.
I would love to se more videos on this press.
What did this project cost you?
About 800
@@TheJessehart05 is that with the price of the knife fingers or did you fab those too? Asking because im lookin into building one for bends of 3/16 steel 30" wide. Ill be constructing it for about 60 tons.
@@tribounty1392 I made the fingers and the beam they are bolted to
@@TheJessehart05 ty very much.
Just keep that right hand out of the way and you'll be fine!
Robert Unversaw . I was thinking the same thing 😎
Plans for this?
Nicholas Kin . Sorry it's from scratch. 4x6x3/16 box tube.
TheJessehart05 no prob, u think this would hold up to 40 ton jacks?
Nicholas Kin . More bracing and thicker metal it will hold. Alot depends on your lower die radius.
