I HAVE GIANT MECH ARMS! (Aliens Power Loader Part 7!)

I HAVE GIANT MECH ARMS! (Aliens Power Loader Part 7!)
we

have

to use all three stupid fittings to make this work well I think that's the last time I'm gonna pinky promise hey guys it's time for another update on our

power

loader

series in the last episode we resumed the project after about a six month hiatus we were able to get the second arm mostly fabricated we were able to test the wrist joint and we even did a few tests with our encoder system to

have

digital control of the arm on this episode we'll be finishing the second arm
i have giant mech arms aliens power loader part 7
there's still some welding we had to do completely building and welding together and assembling the gripper we're going on a shopping trip to pick up all the hydraulics and supplies we need for the project bhajans gonna start designing the shoulders which is the next major

part

of the

power

loader

and we're hopefully going to

have

everything ready to be shipped out to be painted and in the last video i also pinky promised that we'd

have

a video ready for you guys by february 13th
which means we've got a lot of work ahead of us and we're probably gonna

have

to work some overtime to get all this stuff done Ceramics so before we put this arm back together and build a second arm we want to do a better job on the paint what we're doing is we're taking these away to get them sam blasted so we can repaint them properly i think we're gonna use implement paint which is used on tractors so it's very hard enamel finish that should be a lot better than this
gem clap whoa whoa a steal so last episode James made a pinky promise i pinky promise i pinky promise so now I'm here designing the shoulders while everybody is slaving away trying to finish the second arm as we've done culture of the completion of both

arms

we need to start looking at the shoulder system and here's what I've come up with a design basically we've got an H frame out of box tube which holds the two

arms

together and makes the whole entire body rigid behind it
we're using two hydraulic cylinders to actually push and pan the

arms

in and out there's one for the left arm and one for the right arm the shoulders are one of the most critical

part

s of the

power

-law design as you must be extremely rigid in order to hold the weight of both

arms

and whatever you're picking up as well as the extremely precise to allow the

arms

to be very accurate at the very front of the gripper the safest Tama on the design I'm actually gonna reuse all the mass
from the wrist joint in order to calculate and figure out the linkages for having the arm pivot up and down last episode you saw us finish the wrist rotator and that completes one full arm you also saw that we started welding together the bicep the forearm and the wrist that means we still need to finish the second gripper the wrist rotator all the mounting joins and by all the hydraulics perhaps one of the plates is warped and it's not fitting together as well as we want so I'm
just patting as many clamps as I

have

top plate of this yeah so I can see this step here can't quote me on this but I think we

have

enough claims in either case the next video will come out on February 13 our problems last time we went shopping for the apparel odor we actually bought everything in like four or five trips and this time gins like right you're gonna go do it all in one so hey that's gonna rack up a huge bill and be a probably missed a bunch of stuff so let's
i have giant mech arms aliens power loader part 7
didn't go back at some point I got I get a medium double-double a large dark roast with an espresso shot risotto to get some

part

s to the

power

loaded of comments being like whoa there's a store where you can buy like hydraulics and things and it's pretty normal here in Canada and the US the main customers stores like this are farmers because farmers are the ones buying the hydraulics to fix the tractors and whatnot and most countries

have

farming so there's got to be some
hydraulic stores out there just gotta find this is the farm look how fast our bill is going up I think we're already over half person totally we need about three dozen fittings and they're all different sizes styles and angles okay basically we need to be able to run each arm to a central pump clean to make a split connection that's gonna split the pump outlet and the pump Inlet we want to be convenient as well so what we're trying to do is we're trying to use these quick
disconnects to be able to remove the arm very easily so if we want to change how the pump which is disconnect the arm look at a new pump these are literally pull that she bath and they pump right on just like an amount of connection 90 degree juice you just picked those up 90 degree V t2 380 I see you guys might be wondering what MPT J I see an orb move well MPT stands for national pipe thread it's a slightly tapered thread that basically the more you tighten it the tighter it gets
Jesse's on the other hand our far superior component because a jic fitting is a face sealing fitting so it's actually got this which pushes into a seal and then there's another seal along there and the beauty is most jic things can also rotate then we introduced something called the orb fitting I don't really know much about org fittings but it's basically a straight thread with again a face seal and it seems like hydraulic cylinders and I draw it pumps use that thing so the
beauty is because of our fantastic system with North America like the US and Canada and every other standard out there we

have

to use all three stupid fittings to make this work or the GIC jic two MPT MPT jic i don't think we

have

any orb to MPT though yeah fun facts we're gonna need another organizer for all this all right think we're about through most of the list the first list now let's start taking bets okay what's the total the 2100 there we going Price is Right rules
you go over we all lose all right three Kevin 21 3,000 3,000 and $3,200 two thousand eight hundred and thirty eight dollars and thirty four cents I mean I mean Darryl wins nice job girl but really I'm the real winner because I get to pay for it this is just for one arm of the

power

loader

when you're done online look up the hack Smith there we go just give it a bit longer and she's going to be glowing holy crap wait here one second this article Tori so all that is for one arm
i have giant mech arms aliens power loader part 7
we've already built one arm and our rebuilding in secondary ago I like the car that you built that was I'm a jerk yeah that was really cool it's almost done video be next week or the week after guys who did awesome yesterday if we do the same thing today we probably only

have

to stay overtime we'll

have

two fully working

arms

and hopefully by this weekend we might even

have

the shoulder design done some next week you might

have

count the shoulders done in this race needs these
molds to be drilled out and sized up and reach aft to half inch bolts do you

have

trouble drilling holes and large steel plates do you

have

a hard time keeping the drill straight to make sure your holes are perpendicular are your

part

s too big to fit on the drill press what you need is a mag drill you need a magnetic drill press so how does it work so basically you've got your drill here it's got a linear slide that goes up and down but the real magic happens over here see we've got
this big electromagnet unit right here so you can basically set this on your steel plate align your hole where you want to drill it then you hit the on button and then it produces over a thousand pounds of magnetic force holding it to the steel plate allowing you to drill a nice clean perpendicular hole through your steel right he's this mag drill please consult your physician about magnetic field fence the following side effects of magnetic field press is named for the scenic irritation
likely death daddy she's free--free magnification in adjustable so grinding yes we should do that in the shipping container should we all you want to second we get this cannon over here now building a real-life version of the

power

from

aliens

is quite a challenge but when you're problem solver by nature anything's possible and with a resource like the Internet you really can learn how to do anything on your own today's video sponsor is brilliant org a fantastic resource
to help you learn new skills it's a problem-solving based website and app with a super hands-on approach for learning a wide variety of stem topics from solar energy to special relativity these subjects

have

storytelling interactive challenges code writing and probes to solve to make sure you truly understand the topic anyone can read a textbook but until you actually apply what you learn you're not going to remember it which is why brilliant is so great at teaching technical concepts
basic problem solving will help you in every aspect of life brilliant also just launched a brand new course the chemical reaction starting from simple puzzles you'll see how energy charge and probability determine the basic behavior of chemical reactions in real systems from the cells in your body to batteries and even internal combustion engines try brilliant org today using my link below and start your journey of becoming an Axman just like me today well I think that's the last
time I'm gonna pinky promise something the team had to spend a ton of overtime but we managed to get the second arm done and even the second gripper so now we've got both

arms

done they're sandblasted and we're ready to send them out to be painted a nice Caterpillar yellow in the next episode we're gonna start building the shoulders and then designing the torso this thing's really coming together and in case you guys are curious this already represents tens of thousands
of dollars of engineering R&D costs so if you guys want to help support this project and our channel check out our new merch there are links below
