I don't understand what is the point of all the electronics and the computer/key pad, if you have to adjust the angle manually? What is the point of all the electronics?
Dan Since you made your 18 video series, have you acquired a 3-D printer? I was told that the water jet can also have a Z axis and cut in 3-D - I am having trouble visualizing this considering the material sits in water. Regards Randy New Orleans, LA
AISLE3B I don't have a 3D printer as most of the stuff I make is either high precision or high performance (i.e. metal, ceramics, specialized plastics). A Good metal 3D printer is very expensive, about $500,000. It is better to design things to be made on the waterjet, as the volume production methods are closer to WJ than to 3D printing. Using the WJ for 3D is a waste of time.
Dan's presentation is good - I learnt how to make stiffened bends more easily. But Dan has no idea about safety. He puts his fingers repeatedly between the dies with the power on. It would only take a slip and fingers are lost. A sheet metal fabrication company I have used a lot has a very simple policy - the first time you put your fingers in you get a written warning. The second time you get another written warning. The third time you put your fingers in, you get the sack.
Hi Dan, hope you're doing well. I am looking for recommendations on some good sheet metal design/manufacturing references. I recently purchased the ASM Handbook Vol. 14B Sheet Forming as well as Tool and Manufacturing Engineers Handbook (Vol 2: Forming) but looking for any other gems out there. Thanks in advance and I can't wait for new content. Take care.
Can't think of a book, but best is to get a tour of a large local sheet metal fabricator and ask them to point out to you well designed parts and poor designs.
Dan I have seen some press brakes like yours for sale, but none of them have the keypad console as yours does - may I ask what added functions it adds to the machine opposed to a machine without the console. Do you think it would be false economy to buy a two foot machine over a 4 foot machine? Is there any particular areas to look for when buying a used machine, like do the air pistons need periodic maintenance? Regards
Hi Dan I think you said that you were using a 20 ton brake. Does that mean that if you were bending a sheet of metal across the length of the brake that there would be 20 tons of pressure applied across the entire length? And if you were doing a smaller piece (five inches wide) would there be more than 20 tons applied, even though it is a 20 on machine? I see louver dies for sale on internet (about five inches wide) that I would want to use on 12 gauge galvanized sheet metal - have you used your machine with a die to cut the sheet metal? I really like your videos and am sure they have been helpful to a lot of people - can they be purchased on a cd? Regards Randy
The pressure is always 20 ton, even on a smaller piece. This is not a problem. If it is, like when bending soft materials, the brake has an adjustable stop on the die travel. 20 ton should be sufficient to cut 5" louvers on 12# metal, but it depends a lot on the die design. When I make louvers I cut them on the waterjet first, then use the brake to bend them. You can do the same with plasma cutter. You don't need a CD, you can download all videos from YouTue using one of the standard downloading tools you get for free from the internet. Cheers, Dan

Bending the rib was worth watching all your videos...thanks!
My jaw dropped when I saw it. Just brilliant.
Right?! 🐸 Just Rib-It
The undo button, ha! I laughed out loud!! 😆 You have an amazing shop and I have learned a lot from your videos, thanks!
I'm cringing every time he puts his fingers in the press
I'm in awe of his genius modifications to this machine.
Great tutorial thank you for sharing!
thx!
Ah! I never realised how the little rib could be formed at the same time as the bend! I've learned something (actually, a few things - thank you!)

brilliant set of videos should be permanent additions to RUclips and linked to google search . I found this from another link about laser pointers

This series of videos is fantastic! Great class

Hi . ive got the same machine but i cant find tooling for it. do you know a place to buy the toolings ? im in the uk . thanks
I bought one long (48") bar and cut it into the different length tooling with the waterjet.
7:44 Yikes - watch those hidden personal fingers!!
Thank you sir!!! This world keeps getting better because of people like you! 52,500 views! for this one you've taught 52,000 learners!

Dan Gelbart Thanks Dan. I'm actually at a shop right now trying to work through some gusset design challenges. Thanks again and take care.
Dan
Do you have an ironworker in your shop?
Regards
Randy
No. Still looking for an excuse to buy one.
I've seen those stiffened bends before but until now didn't know how they were created

It is just a faster way to prest the back gage, can be added later. 2' or 4' depends on your needs.
Thanks again.
It’s an Atek Bantam 24 ton with the Smart-gage control. Looks like the B424.
Pro tips!
this series is epic!
This guy make me nervous punting he´s finger inside de machine like that.

After you cut the louvers first with a waterjet , how do you bend them with the brake?
Randy
AISLE3B By setting the depth stop to just bend the 45 deg, not 90 deg., using a top punch narrower than louver.
Dan - thanks, you helped me a lot.
