[00:00] Fun fact: it only takes about 1,000 lbs worth&nbsp; of pressure to completely shear off a human&nbsp;&nbsp; finger. This tidbit of information will come&nbsp; in handy later. Here at my wheelchair factory,&nbsp;&nbsp; of off-road wheelchairs this summer as&nbsp; we relaunch our redesigned Rig 2.0. And&nbsp;&nbsp;
[00:18] this machine, secretively wrapped up&nbsp; in white, is going to help us do it. The brake press weighs about 12,000 lbs. So, we&nbsp; have this custom forklift—a rigging forklift—which&nbsp;&nbsp; has a crane on the top. But it's also interesting&nbsp; that the back of the forklift can extend farther&nbsp;&nbsp;
[00:33] out to better counterbalance the weight that&nbsp; we have on the front. Take a look at this&nbsp;&nbsp; over here. Kind of fun. Pretty heavy-duty&nbsp; equipment to move heavy-duty equipment. This is what we are trying to build with our&nbsp; new machine. What you see here is a few of&nbsp;&nbsp;
[00:46] our one-off prototypes—prototypes that we've been&nbsp; using for testing and filming for the past year.&nbsp;&nbsp; Building them one at a time, though,&nbsp; is slow and rather expensive. So,&nbsp;&nbsp; just like Henry Ford did with&nbsp; the automobile back in 1913,&nbsp;&nbsp;
[00:59] we'll be mass-producing our off-road&nbsp; wheelchairs to bring the price way, way down. There are about 5 1/2 million people in the&nbsp; United States who use a wheelchair as their&nbsp;&nbsp; primary means of mobility. And our goal is&nbsp; to build enough of our Rig 2.0s for everyone,&nbsp;&nbsp;
[01:13] which is where our new machine comes in. It's&nbsp; called a Trump TruBend 2100. And while its&nbsp;&nbsp; name is rather unfortunate, its abilities&nbsp; are extraordinary. The TruBend 2100 is a&nbsp;&nbsp; 100-ton CNC press brake, and we can use it to&nbsp; turn 2D sheets of metal into three-dimensional&nbsp;&nbsp;
[01:31] Basically, this has the crushing&nbsp; force of 20 full-size elephants;&nbsp;&nbsp; but since we don't have the resources&nbsp; to feed that many elephants, we bought&nbsp;&nbsp; we have to get our laser-cut parts from inside the&nbsp; laser. A lot of our off-road wheelchair parts and&nbsp;&nbsp;
[01:51] wheelchair parts use sheet metal for, like, the&nbsp; seatbacks and kind of like the frame design. So,&nbsp;&nbsp; we put a giant 5x10 sheet on this side, and it&nbsp; gets pulled into the laser where laser beams&nbsp;&nbsp; can cut out the exact dimensions we need.&nbsp; The laser is what helps take the 2D flat&nbsp;&nbsp;
[02:08] sheet metal and gives us a dimensional shape&nbsp; that we can then make 3D with the brake press. Flat sheet metal is one of the most common&nbsp; ways metal is manufactured and distributed.&nbsp;&nbsp; And we can use a literal laser beam to cut out&nbsp; the intricate shapes we need for the off-road&nbsp;&nbsp;
[02:22] wheelchairs. Basically, the CNC laser concentrates&nbsp; a beam of light onto the surface which melts the&nbsp;&nbsp; metal into a molten lava. Then, high-pressure&nbsp; compressed air blows the molten metal out the&nbsp;&nbsp;
[02:34] backside of the cut. Thumbs up for that. It's&nbsp; an extremely impressive machine. If you want&nbsp;&nbsp; to learn more about lasers, I did make a whole&nbsp; video on this guy when we bought it last year. Our wheelchair factory is growing super fast&nbsp; thanks to you watching our videos. And here&nbsp;&nbsp;
[02:47] comes all of our laser-cut parts. The sheet&nbsp; is actually still really hot because of all&nbsp;&nbsp; the energy that went into making the cuts.&nbsp; But as you can see, some of the parts are&nbsp;&nbsp; already coming out of the metal. This piece is&nbsp; going to become the base of the battery box,&nbsp;&nbsp;
[03:02] and this will become the lid. They're flat right&nbsp; now, but not for long. Basically, any shape we&nbsp;&nbsp; can dream of out of aluminum or steel, this laser&nbsp; can provide for us really quickly. We can probably&nbsp;&nbsp; cut out all the individual parts we need for a&nbsp; single off-road wheelchair in about 20 minutes.
[03:17] Then, it's time to take the parts over to our&nbsp; press brake. This machine is going to help us turn&nbsp;&nbsp; flat sheets of aluminum into our next-generation&nbsp; off-road wheelchair. Creating something out of&nbsp;&nbsp; nothing doesn't happen by magic, and it doesn't&nbsp; happen overnight. And really big machinery like&nbsp;&nbsp;
[03:32] this is what helps make it happen. We got this&nbsp; machine used for about $100,000. But luckily,&nbsp;&nbsp; and decided to hook us up with their heated and&nbsp; cooled massaging office chairs and help offset&nbsp;&nbsp;
[03:48] a significant portion of the brake press machine.&nbsp; So, thank you, HBADA, for supporting the factory. These chairs are pretty epic, by the way. It's&nbsp; called the HBADA X7 Smart Ergonomic Chair. And not&nbsp;&nbsp; only does it have automatic lumbar smart tracking&nbsp; to make life easier on your lower back, but it&nbsp;&nbsp;
[04:03] also has 8D biometric hand massaging built right&nbsp; in. The chair can auto-massage you after prolonged&nbsp;&nbsp; sitting with three levels of red light therapy&nbsp; that heats up deep into your muscles. Imagine&nbsp;&nbsp;
[04:16] being at a spa while gaming, because that's what&nbsp; you get with the HBADA X7. The automatic lumbar&nbsp;&nbsp; support moves with me automatically every&nbsp; time I change position. There's a magnetic&nbsp;&nbsp; charger, a 5,200 mAh internal battery for 3 hours&nbsp; of full-power use, and dual-fan ventilation built&nbsp;&nbsp;
[04:33] right into the seat to help keep all your bits&nbsp; cool, and a super comfy zero-gravity recline. of its own. But until then, there's a link in&nbsp; the description; because if you're sitting down&nbsp;&nbsp;
[04:46] for most of the day, it's probably time to treat&nbsp; yourself to something nice. You can give yourself&nbsp;&nbsp; a promotion with the HBADA X7 Smart Ergonomic&nbsp; Chair, and the link is down in the description. But let's get back to building our off-road&nbsp; chairs. We might not have automatic lumbar&nbsp;&nbsp;
[04:59] support, but the improved suspension makes&nbsp; up for that. Instead of outsourcing our seat&nbsp;&nbsp; manufacturing, which could cost us hundreds of&nbsp; dollars per seat, we build everything here. So,&nbsp;&nbsp; it only costs tens of dollars per seat. We&nbsp; have the tooling set up in a way that each&nbsp;&nbsp;
[05:12] of the operations has its own set of teeth.&nbsp; Uh, what's interesting is that they call this&nbsp;&nbsp; top piece the "jaws" and then obviously this&nbsp; the "teeth." So, it's like a big old mouth&nbsp;&nbsp; that just clamps down on the metal. So, each&nbsp; of these stations is a different operation.&nbsp;&nbsp;
[05:26] And the stops on the back make sure that we're&nbsp; not pushing the metal too deep into the machine. The CNC brake press knows the length of&nbsp; the flange that we're trying to create,&nbsp;&nbsp; and the back gauges make sure that we don't screw&nbsp; it up. Each of these individual teeth—this one,&nbsp;&nbsp;
[05:40] the lower portion—is called a die, made out&nbsp; of hardened tool steel. And then up here,&nbsp;&nbsp; these are called the punches, and they have like&nbsp; a little indention at the top which helps them&nbsp;&nbsp; clip into this groove and hang where we tighten&nbsp; it with these Allen bolts here. But these allow&nbsp;&nbsp;
[05:56] us to set how long each of the bends is going to&nbsp; be, up to a total of 10 ft. So, we could put a&nbsp;&nbsp; whole flat sheet of steel in here and bend it&nbsp; at the same time—assuming, of course, that the&nbsp;&nbsp; bend itself wouldn't require more than 100 tons,&nbsp; because that is the limit of this brake press.
[06:10] One way to keep all of our fingers intact is a&nbsp; laser beam system that watches where the tips of&nbsp;&nbsp; the punches are at. Kind of like the laser below&nbsp; your garage door. If anything disrupts the laser&nbsp;&nbsp; beam that's not the punch itself, like a finger&nbsp; or an arm, the brake press will stop and hopefully&nbsp;&nbsp;
[06:25] not shear off any of your digits. It's super nice&nbsp; that the machine does all of the measuring for us,&nbsp;&nbsp; which saves the operator a lot of time as&nbsp; we build our off-road wheelchairs quickly. What's interesting, though, about this TruBend&nbsp; 2100 is that obviously dealing with the downward&nbsp;&nbsp;
[06:39] force of 20 elephants stacked on top of each&nbsp; other, or the weight of two whole excavators,&nbsp;&nbsp; the bottom jaw is bound to flex. So, what Trump&nbsp; has done on their press brake is to hollow out a&nbsp;&nbsp; cut in the super-thick lower steel plate and adds&nbsp; reinforcing hydraulics on either side of the jaw&nbsp;&nbsp;
[06:56] so that it can offset the crowning or bending of&nbsp; the tool itself. The lower hydraulics compensate&nbsp;&nbsp; for the natural deflection of the bed, which is&nbsp; the lower part, and the ram, which is the upper&nbsp;&nbsp; portion. The amount of flex is predictable, so&nbsp; the compensation needed to offset that flex is&nbsp;&nbsp;
[07:13] also predictable. The large hydraulic pump on&nbsp; top is regulated by two proportional valves&nbsp;&nbsp; which allow the hydraulic fluid to flow on both&nbsp; sides of the ram for super precise positioning. It's hard to see with the thin aluminum, but I&nbsp; got some 1/2-in steel plate that we can also try&nbsp;&nbsp;
[07:28] bending as well. A 1-ft segment of 1/2-in steel&nbsp; plate would probably require about 40 or 50 tons&nbsp;&nbsp; worth of pressure to bend. So, our press is&nbsp; still overkill for even 1/2-in steel. But,&nbsp;&nbsp;
[07:40] it's super cool watching our laser slice through&nbsp; the steel like butter. We are cutting out the&nbsp;&nbsp; shape of an oversized wrench just for fun&nbsp; so we can turn it into a wrench bench. The steel wrench is a tad more complicated&nbsp; to place inside the opening since we don't&nbsp;&nbsp;
[07:54] have a flat spot on the flange of the&nbsp; CNC back gauges to reference off of,&nbsp;&nbsp; but I'll just eyeball the lines we scribed&nbsp; on the metal and hope for the best. Glorious.&nbsp;&nbsp;
[08:09] You'll notice that the bottom die we are&nbsp; using is quite a bit larger this time around,&nbsp;&nbsp; since the radius or curvature of the metal is&nbsp; also going to be larger. The punch on the top&nbsp;&nbsp; is also quite a bit thicker. And the coolest part&nbsp; that's now easier to see with the steel is that&nbsp;&nbsp;
[08:22] the press brake actually bends the metal past&nbsp; the 90° we want so that it will spring back to&nbsp;&nbsp; the angle we request. Intelligent machines are&nbsp; extremely helpful, and luckily metal is pretty&nbsp;&nbsp; predictable. As long as the machine knows what&nbsp; type of metal it is, it can predict the flex.
[08:38] It's nice. That's a good height. We're&nbsp; going to have a nice wood seat on it.&nbsp;&nbsp; You've got to try this. It's nice. I'll have&nbsp; to add a wood top to our wrench bench later,&nbsp;&nbsp; but I think it turned out super cool. And speaking&nbsp; of intelligence, like I mentioned earlier,&nbsp;&nbsp;
[08:52] it only takes about 1,000 lbs to shear&nbsp; off a finger. And this machine would&nbsp;&nbsp; probably be capable of shearing off about 200&nbsp; fingers all at the same time. We'll have to&nbsp;&nbsp; save that test for a different video. But&nbsp; luckily, there's a level of safety with a&nbsp;&nbsp;
[09:04] laser sensor to keep that from happening on&nbsp; accident. Protection is always a good thing. we could basically reconstruct society&nbsp; from scratch or build really cool,&nbsp;&nbsp;
[09:16] inexpensive off-road wheelchairs. I'll leave a&nbsp; link down in the description for the HBADA X5,&nbsp;&nbsp; as well as we are doing pre-orders for&nbsp; the off-road wheelchair. That'll be down&nbsp;&nbsp; in the description as well. Thanks a ton&nbsp; for watching, and I'll see you around.
