How To Bending?!

Little follow up on the weld cart build where I did a lot of bending but didn't pay it much mind.
Sheet metal, specifically, but this goes for all bending in general (sheet, tube, pipe, bar, spoons etc etc etc)

[@A.Lifecraft]

With metal that is mostly incompressible, one could calculate this by the crosssectional area. The outer curve will be pulled inwards while surplus material from the inner curve pushes outwards, so the neutral axis might do all kind of weird things and wander within the material, but in the end the area of crossection represents the volume of material that has been moved but it will still be the same volume.

In that time I’ve typically used slitter, stomp sheer, box/pan break, and a standard 10 foot break. Pipe lock and Pittsburgh machine. Good to see some tin knocker content. Thanks for the vids!!

[@WhereWhatHuh]

Back in my days as an electrician, in a galaxy far far away, we used bend setbacks all the time in bending EMT and "Rigid" conduits. It was not uncommon to see an electrician mark out all the bends in an entire 20' piece, then start at one end and make every bend in order all the way down the pipe before sticking it into place -- where it would fit precisely. Maybe something like a 1/2" offset to go from a surface mount box to flush with the wall, poke through a deck, then a 90* bend, then maybe a 5" offset to go back up flush with the bottom of the deck, then a tiny 1/2" offset to go into the other surface mount box. The "cheat" there is that the setbacks were usually marked on the bending head, and the good heads even had the factors by which a given offset would shorten the work -- for example, a 45* kick would be 1.4, so if you needed to offset 5" x 1.4, you could make two marks, 7" apart, make opposite 45* bends with the "back" of the bend at those marks, and you'd have a perfect 5" kick. Yeah, math nuts, it should be 1.41424, so sue me. And, yeah, go over 360* total bends in a run and you'll have hell on a stick pulling wires. But so it goes -- make the kicks 30* then. You get the idea. So to make a long post short, great video. Thanks for that.

8:59 Best video tangent EVER!!!

[@Twisty1024]

I came back here several months later just for that. Also just beforehand he says using this tool is 'usually not very pretty' 😆

[@aceroadholder2185]

The most important point Tony made was that drawings or sketches rarely if ever contain the information you need to bend tubing or sheet to size. You have to figure that out for your self. Another point to stress is that for sheet material, especially aluminum, you have to take into account the direction in which the material was rolled at the mill. Avoid bends that are parallel to the way the material was rolled. You are much more likely to get cracks. When you have to bend parallel to the direction of the rolling or extrusion marks, aluminum should be annealed before bending. The easy way to do that is to blacken the material with soot by just using acetylene from the torch. Heat the aluminum with the torch and the moment the soot burns away the aluminum is ready to bend.

[@scottwatrous]

This is true about the direction of the grain structures in aluminum, which is something I have to account for a lot. It's often I have to put parts on a 30-45 degree bias in order to fit them onto a sheet or to make it so that various bends all avoid being along the grain. But, I've bent tons of full-hard 6061-T6 and as long as one sticks to a generous bend radius it should not be a problem with cracking. The problem is almost all people are setup with equipment to do steel sheet which doesn't much care about the bend radius so when I say "I need to just throw a bend into some 6061-T6" they get incredulous or warn me that it will crack. But doing a lot of it, I just use a min 1/8" radius for anything from .016 up to .040 and Bob's yer Auntie. And to do that on equipment setup for knife-edge tin-knocker bends, get some strips of said tin sheet and bend those around the nose of your break to form a shoe. A few layers should do, and with a little tape it'll hold until you're done. Of course it means you'll have to offset your clamps a good margin to accommodate for having a few layers of extra shim, and so that's more work to reset when all is done.

[@aceroadholder2185]

Scott, you're right about bending aluminum (and the most common 6061-T6). But for years I got drawings from MIT engineers who had a lot of book learn'in, but zero experience in actually having to make the stuff they designed. So, "generous bend radius"wasn't in their vocabulary. In the shop I worked in for many years, we did a lot of peculiar work for Sandia and Los Alamos Nationial Labs and GE jet engine division. It was fun because they were willing to pay for doing it. We did a lot of fabrication that pushed the limits of what is usually done in the shop.

[@Gottenhimfella]

Good points, aceroadholder A couple of further related points: IF you don't have acetylene, another way to gauge the (crucial) temperature for hot-bending or straightening alu alloys is to smear the zone with hand soap and heat only until chocolate brown. A decent hot air gun will do the job on small work And if you don't have a male V-punch with a big enough radius to prevent cracking when press-braking alu alloy, a quick and dirty approach is to grind or machine a flat on the end of the punch. Keep increasing the size of the flat until the cracking is eliminated. This works by effectively substituting, for a single 90deg bend, two 45 deg bends so close together that they effectively blend and look like a single bend.

[@throngcleaver]

Or, since (nearly) everyone has access to the internet, just look up the minimum bend radius for whatever metal and thickness you wish to bend... I spent my career in aviation, and bent 6061-T6, 2024T-3, and 7075-T6 on a daily basis. Not sure about other industries, but the minimum bend radius given in aviation pubs, is good for any grain orientation of the metal.

[@JustinCrediblename]

with my .06" 3003 h14 aluminum, I've never worried about bend radius or grain direction. never had appreciable tearing. (depends on alloy and thickness whether a 0 bend radius matters). that needed clarification in this video, and in your comment as well.

[@DFWKen]

Wow! At my HVAC dealership, I owned an 8' brake, stomp sheer, lockformer, and several other pieces of sheet metal equipment. Over 30 years, we made thousands of plenums, transitions, register boxes, and the like from 18 gauge galvanized sheet. I knew that there had to be more to it than bend on the dots. (We used awls to mark the ends of the material to bend). The tolerances for the things we made were not critical enough to cause problems without knowing about the bend allowance and neutral axis that you explained so well in this video. But I always wondered. This video is worth a second (or a third) viewing.

[@diamondflaw]

Just to poke one more thing onto an exceptional video - the difference between the flat pattern length and the sum of the flange lengths to OML (Outside Mold Line, intersection of the planes of the flat outside of the material to either side of the bend) can be referred to as "X-Value". This is effectively the difference between the Bend Allowance and the sum of the Set Backs. The X-Value is very useful when going from a drawing like shown at the end of the video to a Flat Pattern drawing because you can just overlap your distance from the edge of the flange to the bend apex by the X-Value and you've got your FP length. Again, awesome video - I work drafting aerospace sheet metal parts for manufacture and I found zero fault with it, just wanted to contribute.

Very interesting I always do the trial and error method. I worked at a rail car company where we rebuilt wrecked rail cars. We had a humongous press brake that would bend up to 2" thick steel at least 10' long actually I think it could bend a lot longer but it wasn't what I did. All I know is that we all had much respect for the main operator. He was a mountain of a man and the parts he made for us always fit. He would come to the car and we would help him get his measurements these parts weighed several tons. I worked on the open gondola cars that carry coils of steel. They have 1.50 to 2" side's bent like a j and an even heavier sub frame or in the industry it's called a center seal? Watching this video raised a lot of questions that I never thought to ask our wonderfully skilled press brake operator. And I now have an even higher respect for his work.

A Q&D way (and really very accurate) is to measure a piece of scrap, bend it 90, measure the two flanges, and figure the difference between the flat and the result. That will give you the exact bend allowance for the tooling and setup you're using for a 90. Repeat for other angles.

"sheet metal" would actually spell "mathletees" but we can bend the rules a bit this time. see what I did there.

[@bvcxzgt5451]

I was going to go with matheletes

[@Dr.JustIsWrong]

I usually go with #@$&&_$@**%!!!

[@sajinkahnalt]

Mathletes often don’t have the greatest spelling skills

[@hadinossanosam4459]

@@sajinkahnalt Most mathletes I've met are nerdy enough to have pretty damn good spelling skills. Math-leet-es, on the other hand...

[@Alteca1995]

At least there is a little bit of comedy left in the world

[@Iceflkn]

I asked Bender Bending Rodríguez for his take on this video as we watched it together. We laughed, we cried and then we binge watched the rest of your videos!

[@Gruncival]

I just came here from Practical Engineering's Welding 101 video-this is my first of yours, and oh my gosh you're perfect. Never change, HAGS, xoxo. Time to go binge on all your videos!

[@jcs6347]

A couple of questions please. Can you show us application of the bend radius by completing the cell phone holder correctly and to spec's? And, what is the measuring device called you were using that had the vernier scale of the other side, and who makes them? Thank!

[@groushkolb]

I think I "need" one of the measuring devices, what is it called and where can it be bought?

[@bitlunislab]

You are my favorite channel. Would be a dream to collaborate with you... if we had similar topics...

[@Hagledesperado]

Yea, come to think of it, the two of you do have a sort of similar sense of humor.

[@adamonline45]

There is hope, I'm sure you saw he did a collab with Alex French Guy Cooking!

[@shodanlieu7705]

Thank you for these! Your version of edutainment is teaching me a lot.

[@usvalve]

This stuff is really interesting, and this guy keeps answering my questions! Alas, I was a bit short on technical training at school because I did languages. Non-language students were allocated to either technical or domestic subjects determined by a small part of their anatomy. Hard to believe in 2021!

[@michaeldurling793]

It's to bad that school teachers do not posses your ability to make learning fun. I had a blast and learned a lot about bending.

[@maxcohen13]

In England, they call the machine a sheet metal brake. "Bender" means something _totally_ different.

[@ThePsiclone]

nobody has been called a bender here in centuries, I'm sure we'll manage to understand :D

[@Luckingsworth]

maxcohen13 And England has not been relevant in engineering and manufacturing in a long time either, go figure!

[@CreatureOTNight]

Bite my shiny metal ass, as Bender would say.

[@iwtommo]

Jon M - You know where to kick a guy dont ya!

[@Gottenhimfella]

@JonM : Hmmm. Rolls Royce Pegasus / Harrier Jump jets (progressing to the LiftSystem as used on the US F35B Lightning II, the only vertical lift system for supersonic fighters in production? Or their XWB engines in the Aerobus? RR are also front runners to provide engines for Boeing 797.... OK, that's a revealingly thin defence of the Poms, but lets face it, the US is also slipping from relevance as the industrial focus increasingly collapse towards propping up the military complex, and research and development is increasingly restricted to applied science (a glorious present, but no future). Witness CERN, and climate science ... And isolationism will probably only accelerate that decline for both nations (Brexit, Trumpism)

[@leonkitshoff2271]

Greetings from South Africa! I happened upon your channel several days ago and you’ve got me hooked! I’m a qualified tool and die maker and have been molesting steel for 16 years professionally and double that for fun. Your attitude and viewpoints are refreshing and I had to subscribe. Have a good one and I’m looking forward to your next video.

[@routercnc9517]

Cheers Tony I think that was one of your best. Great combination of education, humour, and clear explanations. As a fellow KZbin video creator (not in your league!) I really understand and appreciate the time you have put into the production. Keep up the great work, regards UK.

[@mpc77769]

Yesterday was Thanksgiving. Today Old Tony... am I dreaming?

[@mynameisjo1949]

Not all videos make it into our homeschool, but this one will. 😎

[@autotek7930]

Man your humor is exactly like mine. I'm pretty sure I'd have a blast hanging out and building stuff with you. You having a good time is at best a possibility no matter what your teaching us I'll be watching!

[@alwaystinkering7710]

Nicely done. I do precision sheet metal using Solidworks for a living. This is probably the best explanation I've ever seen. If I can toss in $.02, if you use the K factor of .4 for steel and aluminum you'll be pretty close. K factor will always be less than .5 and normally more than .3. Most shops don't do it that way, they a limited by the bend radii their tooling can produce. Therefore for maximum accuracy they have done a lot of test bends. Measure a sample, bend it 90 with the tooling they have, measure the 2 legs, add them, and record the amount of stretch. Every precision sheet metal shop has a table of those numbers for every thickness and type of material to produce the sharpest bend possible. Most designs assume that kind of bend but if a larger radius or angle other than 90 is specified, we had to do the math. Now software does the heavy math lifting but even then it needs to be set up to match what the shop's tooling can produce. Impressive precision is possible even over multiple bends. There's an art to bending sheet metal that accurately and many tricks to the trade. If you're at all interested in this as a trade, there is a serious shortage of people that can do it and it pays well.

[@bobsnalbert5700]

Dang i haven't even mastered earth and this guy is doing metal bending

[@harisonk]

I'm surprised I haven't found more Avatar Puns. Tony needs to step up his game.

[@p165ter]

My girlfriend says that you have to make longer videos. Apparently its the only time I sit still, be quiet and stop bugging her.

[@sajinkahnalt]

Oof

[@garymucher9590]

Very good video. Anybody that has ever tried to bent sheet metal has had those same issues crop up. But your video shows it so well. Bravo!

[@RJ9mech]

Memories of the late Brass Bull, the dreaded hat section, and setback/bend allowance many moons ago in metallic structures class. Loved the video!
