Hi, Looks Good. To make these really useful you need to have sectioned Punches & Dies of varying widths. Also if the smaller V's are closer to the edge you can get a shorter leg to a reverse fold.
Yep exactly. I have another sectioned punch on 10, 15, 20, 40, 50, 80, 2x100 mm width so I can make different combinations when folding small boxes, etc.
Go ahead you won't regret it. I am using it all the time. If you didn't watch the videos of my Navara build series. Check them and see for yourself.. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lYj3bCHYfJQ.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lBNvOv8oa-A.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pd0TZ6MmaFs.html
Loving what I see, so far, and based on that I subbed after only partial viewing, for craftsmanship, ambition, and engineering! Only this: at 3:20, could thee not have taken up so much of the slop with only a few nylon zip ties around those lugs? Or even simply tapped the existing lugs, without rebuilding? I find that I must constantly struggle with my own compulsion to complicate, as I plan and daydream. No question, though, thy solution is rock solid and foolproof.
Came in mooching a few ideas for my latest project , liked the music , are those linear bearings ? Had similar idea using MC fork legs , what ever lies around ! Subbed
looking at the prices for the sizes of steel he used he mightve been better off buying a full size stand alone fingerbrake (though this on is able to bend thicker steel)
You prolly dont give a shit but does anyone know of a method to log back into an Instagram account..? I was stupid forgot the account password. I love any tips you can offer me
@Blake Pablo i really appreciate your reply. I got to the site on google and Im waiting for the hacking stuff atm. I see it takes a while so I will get back to you later with my results.
u have made very nice machine to make cheap but this is for small job can we do 3 mm and 2500 mm long sheet bend? how many ton jack and hydrolic cylinder power need advice me i want to make thank you
Generally, the formula for air-bending press is: F= (S² x 2 x R) / (1.4 x V) = ........Ton/m F - is the force to bend one linear meter S - Thickness of the sheet material R - is the tensile strength of the material ( mild steel 40-45kg/mm², Alluminium 20-25 kg/mm², Stainless steel 60-70kg/mm²) V - is the opening of the press die. You calculate this based on the thickness of the material you bend. For 0.5-3mm sheet V =6xS, for 3-8mm sheet V=8xS, for 9-10mm sheet V=10xS . So in your case for 3mm sheet metal V=6x3= 18mm opening of the die.
The expensive bits were the punch and dies. The rest is the price of the metal and what the machine shop would charge you to mill the base, punch holder, and the bearing plates.
I disagree. Taking stock and prints to a machine shop for custom machining is still 100% DIY. Nobody owns every tool, the largest shops will still sub certain work out...
less chance of binding if you bend something at the corners of the machine. Also if I was to buy the steel for the shafts and the collars and pay a machine shop to turn them on a lathe I would end up even with what I paid for the bearings and the shafts that are heat-treated and precision ground.
