Ready to talk Power Loader but first, coffee.
In the last episode of the Power Loader series
we finished fabricating the left arm
and started working on the design for the back
and the shoulders in order to get the full range of motion of the Power Loader.
In this episode; we're going to finish the design,
fabricate everything and hopefully get the Power Loader onto the test stand.
So here we have the finished design of the deltoid plate.
This part will actually mount to the side of the bicep.
With this face here. It will bolt on with 12
half inch screws.
Then it has a a few round pieces to hold the cylinder head as well as a few ribs
to ensure the whole thing doesn't bend under pressure.
So we should be good to build it.
Alright so were back in the shop and there's lots to do so lets get to it.
We have to fabricate the shoulders,
grind some stuff, weld a bunch of stuff, fit it all together...
and stuff.
It will be fun! It will be fun.
Here's the actual shoulder piece for the Aliens Power Loader.
It's one of the most critical pieces to get right,
because it will actually join two of the axis' together.
In reference to the model, it actually it combines this back piece here.
As well as the top linkage there
and a very large hydraulic cylinder.
Which has a five inch bore. Capable of outputting almost 60,000 pounds of force.
Now this critical to do a stress analysis on this part
because that is a lot force.
We don't want the part to deform
or break under the full load.
So the stress analysis just finished and we can see that, is a problem.
The red there signifies that the material
is taking to way more load than it's capable.
That would cause some serious deformation and likely failure of the entire shoulder.
We're gonna have to make some changes in the design
to ensure that doesn't happen.
Alright, so we beefed up the material of the side walls
but unfortunately while it's a lot better
it's still not ideal. We're going to need a different solution.
So I just got back from Metal Super Markets
and asked their opinion on the design.
They had really good suggestion.
Why not try a better type of steel?
So lets load up that into the Solidworks model and see if we can get better results.
Okay well that looks a lot more promising.
Lets get that steel on order and continue to build this Powerloader.
That's your plate. That's the AR400.
Very nice and you said that this was how many times stronger than A36?
About 4X stronger. 4X stronger.
It's strong as hell and it's gonna stop a bullet.
So now that we have the full design completed.
We can start working on the box tube.
That's kind of the core of the entire design and getting that completed
would put us on really good trajectory
for completing the Power Loader shoulders.
Does that look straight to you?
Now that every piece of the design is fully fabricated,
we're going to test fit everything
to ensure that all pieces move nicely.
Then we're going to send it off for painting.
Hey! It's me the Hacksmith.
You might of noticed I haven't been in to many of the videos lately.
Have I been off on a yacht enjoying all that Youtube money?
I wish.
No I do actually spend a lot of
time at work.
Like 60 to 80 hours a week.
I basically live here.
I've just been working on the business, not the videos.
Or even the projects really sadly.
The Power Loader project was my dream project idea from 4 years ago.
In fact I announced it publicly the day I met Bogdan at the GTA Expo in 2016.
Bogdan has since taken over the project and I couldn't be more proud of what him,
and what the team has accomplished so far.
It really is incredible.
But as you know building a giant mech on Youtube is rather expensive.
And not to point fingers but another Youtube channel literally went bankrupt
building a mech.
And we don't want that to happen.
Right?
I want to see this project through to completion as much as you guys.
That's why I'm really happy to announce this videos sponsor.

Like I said.
We've been using the platform for years.
I ordered my original CNC Laser Cutter off of Alibaba.com
Which helped me start this Youtube Channel and Business seven years ago.
All of these LED lights in our new facility
we've save thousands of dollars ordering them from a supplier in China off Alibaba.com.
In fact the sales team even came to visit us in Canada to make sure we were happy.
We recently got a hydro massage bed for our employees
Can you guess?
Yup we ordered it from a company in South Korea off Alibaba.com
This month is March Expo 2020 for Alibaba.com
There's over 3500 featured global suppliers
with over 300,000 new products, upgraded logistics,
finance and payment services.
As a part of March Expo we just got this awesome thermal camera from Maka.
Off Alibaba.com
It has a big 2.4inch display.
You can even save images off of USB and has
quick imagery refresh, and as well 300,00 HD pixels.
So you can see exactly whats heating up.
Plus there's tons of other great products
Like 3D printers from the supplier Anet.
or even a giant laser cutter from the manufacturer Bodure.
Learn more and checkout March Expo on Alibaba.com today.

We're gonna try to put the side shoulders on
and then put the biceps on to see how the whole thing moves together.
And make sure we have appropriate clearance everywhere.
Why did you give me the heavy side Chris? You always give me the heavy side.
You always take the heavy side.
Watch your fingers.
That goes on here.
It should be able to do this.
There's a notch to align as well.
THERE'S WHAT!
This notch needs to be aligned to that notch.
Ah.
Can you stop filming for just a moment?
For Bogdans safety I cannot strop filming.
For filming sake I would for you guys to attach the other arm...
but for sanity sake...
I could understand why you wouldn't want to do that in this very moment.
I'm fine to attach the other one.
Who's with me?
Let's do this.
Now all we have to do is install that piece to the fingers.
Which is 400 pounds alone each.
So we got to add another 800 pounds to this thing and then.
We get to add another side plate, hydraulics, all the hoses,
all the decoration pieces.
It's going to be a fun Monday.
Big thank you to Alibaba.com for sponsoring this video.
Alright its fantastic to see the Power Loader coming together.
It's freaking huge.
We've got both arms and shoulders mounted to the body now.
The next step is adding the hydraulics and doing a test
to make sure everything moves as we though it would
in our Solidworks design. Make sure you subscribe!
