Hey guys! It's time for our second update on the aliens power loader build.
In the last episode we talked about the design and started plasma cutting the steel
for the first arm. Let's finish cutting those pieces, go
shopping from some hydraulic parts, get it assembled, welded and then well we can
do our first hydraulics test. Oh, and don't forget to follow us on social
media @TheHacksmith for real-time updates on our projects.
Alright, this plate of steel weighs 600lbs,there's only two fo us here, so hopefully we don't die.
What are you doing there Bogdan? So now we're exploring all the remaining DXF for the
three-eighths steel, and then we'll be able to start welding then we'll be welding forever!
I just have to make sure that all of these don't intersect.
So we forgot the mounting holes for the cover plates,
so we brought them back in the software, but we also had to re-zero the
machine because it ran into the cupboards so
hopefully it's gonna work
That is the bicep of the power loader!
Bicep number two!
Why do you want me to carry it? Here, you're the one who goes to the gym.
So we got our motor, the weakest of all the options. James: Yes, but it comes with a
remote and a valve Bank built-in, it'll be useful for future hydraulic projects
that we can still use this for. And we got the fluid, got a bigger
reservoir cuz that is tiny, got our two cylinders and our final solenoid valve.
You happy Bogdan? Bogdan: No, I wanted the bigger motor.
This is only $1,500 worth of stuff for testing. One arm!
First came here back in 2007. Yeah that's $500 steel now. Look at all this steel!
Oh god.
You gotta use physics!
This is the bicep hydraulic cylinder!
It can put out 30,000 lbs!
20 L of hydraulic fluid!
As you can imagine, building a giant hydraulic power loader
from aliens is a pretty expensive endeavor.
I believe that shopping trip alone was well over $1,000 by itself and that
wasn't even all the parts we need, because of that we're super grateful for
our sponsors who enable us to take on these engineering challenges in order to
make awesome videos for you guys! This video sponsor is world of warships who
helped make building this arm possible. world of warships is a free to play
online game that takes wit and expert strategy to dominate the seven seas, it's
the perfect balance between both action and strategy which really makes it a
thinking man's action game. You get to command a massive naval fleet with some
of history's most iconic war vessels. With changing weather and over 30
million players worldwide no two missions will ever be alike, what I like
most about the game is the attention to detail the game models are super
accurate because they actually base them off of real-life 3d scans of the ships
and with over 200 ships from 11 nations there are so many different ways to play
updates are constant which ensure new experiences new missions game updates
and special events. Play today using my link below in the code playlangley2019
and you'll receive 1 million credits, the premium USS Langley aircraft carrier, 3
days premium time and more. The aircraft carrier allows for a completely
different form of fast-paced world of warships gameplay. Plus by downloading it
you ensure our channel can afford to keep building this massive power loader!
This bushing is a little tight so I'm going to fix it.
That's better.
I need a little bit more off of that.
And that's the wrist joint!
As long as I got my tolerances this should just fit into place.
Why do we make such heavy projects!
All right it's time to look at some of the hydraulics for the power loader.
Now, funny enough my first job out of engineering school was actually designing hydraulic
systems for injection molding machines for a company called Athena automation so
I have actually done some of this stuff before a long time ago but I've never
actually assembled it myself so this should be interesting.
Right now we've got our manifold block which we can connect three closed Center
directional control valves to and basically we're able to control up to
three cylinders from this block so I've got all these fittings which I mean to put
in there which then can connect to these hoses and then we can connect everything
together with our pump and hypothetically move some oil around.
Okay so we can tighten this guy in. It's quite tight!
That is snug!
Let's see what this looks like. So for testing we got some pre-made hydraulic hoses standard
lengths this one's three feet long I got some four foot long ones when we
finalized the design we'll get custom length hydraulic hoses
Okay next cylinder!
All mechanical portions are
done now which means can do a test-fit and potentially test the hydraulics.
So Bogdan, you and me will lift and Ben can hopefully line it and this is the tricky part
And this is the tricky part
we have to put the valves on the inside of the arm, attached to this manifold block.
Fits pretty slick! All right so we got the valve bank installed now we just have to add in the wires
I'm just gonna install all of these plugs. All right so all the fittings in the manifold block are tight
now which means when we add the hoses we just have to tighten those ones, but this is the
evidence of me saying everything is tight so hopefully nothing bad happens.
That's how engineering is done!
okay so we got a pressure gauge, we got some
manifold connected to the hydraulic pumps, we have one remote right here
the pump has a built-in two-stage valve bank, so pressuring one-way pressure out the
other. We'll just be doing one way because we're adding pressure here and then
we're using these valve banks that then control the ends of the cylinders. And because
they're close center we only have to attach four hoses you just have never
press the other button. Don't press the button!
Now, whatever you do don't push this button okay.
No! That's the button that will kill everyone!
First time using hydraulics!
Let the record state this was Bogdan idea to extend the cylinder
before attaching the arm. So! Pressing this button turns the pump on.
Alright this is still not great but everything else is alright.
It's not gonna crash into itself right?
Alright so this arm can curl... It curls around six to eight thousand pounds so
that means we actually hold a six thousand pound barbell right here. That's
more than a car weighs so with both arms we should actually be able to flip or lift a car.
Well, after a week of work- James: It wasn't even a week. Friday Saturday we built this in five days!
I didn't think we could do it! Everything works which means we have to take it
apart again, clean it up a little bit more, paint it, drill some more holes then
we can put it back together again and then it's done for now until we build
the other one and then we build the body. Bogdan: Knowing how much work and effort went
into this and just not even, like, building it. Just assembling it. Just putting
everything on while it's super heavy and really cumbersome. James: It took two hours just
assembling two hours of footage for the editors to go through.
Oh yeah, this is a temporary test hydraulic
system that's why it's so slow it's just so we can test to make sure the
hydraulics work in the end we're probably gonna actually have like a gas
engine on the back of the mech and it will have a much higher flow rate so
the arm should actually be like...
Alright, that's the end of whatever part of the video
Alright it's really starting to come together. So like I said last
video we're gonna be releasing one video on the series per month going into a
little bit more detail on the project than we normally do for our videos it is
an extremely big project so we're gonna do our best to stay ahead on this
project to ensure you guys get consistent updates once a month but if
you're dying to see more make sure you follow us on Instagram where we post
real-time updates as we work on the project in part three we'll be painting
reassembling the arm and doing our first real hydraulics tests including lifting
people after that it'll be a video on our jaws of life the claws of this bad
boy that will be able to crush xenomorph skulls!
Make sure you subscribe this is our biggest and best project yet. Plus I've
got quite a bit of reading to do...
