I made a Giant Mechanical Pterosaur out of cardboard!

[Music] hello again this video started out as a nice simple project but things got out of [Music] hand grab your apple pie glue stick or your favorite glue flavor because we're making a big bird this is pretty big but is it big and enough now we're talking sorry Shena terce we're doing Chia yongo terce the paper model I started with had four rods on the big one I want to add an additional pair of rods to animate the wing tips now let's get [Music] cutting this is some cardboard that I salvaged from Home Depot I'm going to use this Steam and hot glue gun on this cardboard hinge to connect the wing segments now the wings can fold like this same thing for the larger panel and two more hinges for the body it's getting bigger now we can make it three-dimensional with some cardboard ribs cover those up and this piece will turn into the tail after we give it a little pinch tail that's the top now the underside will need some strong pectoral muscles to Flap those [Music] wings now I need to transition from the muscle into the [Music] neck I don't really know what I'm doing here we need a long neck and the comically large head but he's in Good Company goodbye two-dimensional beak we've got a three-dimensional [Music] beak like [Music] that sorry about that can't forget the upper Peak when you don't know what to do just glue layers together now this will be our face shape I made this smaller template to Mark out scoring lines that's where I'll cut the back of the the panel so that when I bend it it bends where I want it to that actually worked this gets glued onto some cardboard supports and the top of the head gets glued flat there's a little Gap in elevation here perfect for this beak detail this piece just needs a little twist perfect more perfect I'm using little pieces like this for support but they'll get covered up later it's working so far this piece needs to be flush so I'm cutting the edge at an angle like that and here's where it goes on the throat this is a funny piece I'm bending a curve into and that goes right there next I'm going to use this paper bag to cover some seams and [Music] gaps all of these unsightly seams need to get covered as well for the eyes I'm going to form this piece of paper around the [Music] socket now that it's formed I can just trim off the [Music] excess I'm using paperboard from a cial box to create the eyeball and [Music] eyelids the body and head are now complete back to the wings for a moment I'm going to make the Arms by curving these 2D cutouts but they don't look like arms oh I see now we need some hands there we go now we can walk and hold stuff this is how the hands should sit with the Palms facing outwards now I need to do it all again for the underside now all the hinges are sandwiched between a top and a bottom wing panel the cardboard sculpting is complete now we got to make it Fly let's start by adding some mounting hardware I'm using brass machine screws with a nut and some tiny universal joints I found on [Music] Amazon this will allow the rods to Pivot in any direction now for the crankshaft this is what will create the animated effect after doing math I'm ready to cut the [Music] pipe nice these elbows will provide all of my right angles back to the hot glue to build a mounting point we need this to hold the majority of the weight I had to do some surgery here hot glue solves all my problems he's ready to fly but it's not time yet we need to build a [Music] base [Music] now I have a template to trace out three more of [Music] these the crankshaft will go in this hole and these holes are for towels and that gets routered to give it nice round edges I designed it so that everything comes apart for transportation and [Music] storage normally you would solder copper pipe but that would prevent me from making any adjustments so I'm going to try this copper glue which works pretty well when they're not not moving the next step is to attach the rods I looked everywhere to find the right fitting but I couldn't find anything that would [Applause] work so I had to design my own here's what it looks like duplicate it for a full tube and a second piece holds the rod now the rod can move from side to side while while these two Wings prevent it from moving too far for the center Rod I'm using a pipe to hold all that weight I'm using a 3/4 in Te with some 3D printed bushings to fit over the/ in pipe and a screw so it can be disassembled the center pipe's holding the weight well but the brass rods don't let's try 316 Steel it moves but not great the wing tips are bending too dramatically so I'm going to shorten them and change the angle now that the mechanism is mostly worked out I can go back to finishing the bird let's start by beautifying the stand so we're going to take the marshmallow and we're just just going to dip it down let as much excess chocolate come off these copper pipes tarnished as soon as I looked at them Google said to use citric acid in dish soap so that's what I'm going to try oh there it is it actually works a bit Pinker than I expected after rinsing them I sprayed them with a coat of clear [Music] lacquer I was thinking about not painting it but then my nextdoor neighbor bullied me into it so let's spray paint Bas coat now let's switch to acrylic craft paint some brown that's disgusting black and water I'm using colors based on a real animal but I made up the pattern on the way wings now that the messy base colors are down I'm going to finish painting indoors and give them a bigger Crest let's start with some acrylic [Music] markers the animal I'm referencing is a duck called the spectacled Ider I assume because of its spectacled look time to break out a big brush for the beak [Music] and let's whip up just the right [Music] green I'm going to call it spectacled Ider green or mold green I want to keep this paint job fairly stylized with clean lines I'm using two additional colors to create a warm gradient as well as [Music] shading the Ider eyes are beautiful blue some finishing touches and that open mouth is panting for a tongue made from a frozen pizza box the head is finished now let's bring some of that eer green to the wings I'm mixing that with cream and white to create a nice gradient here it is taking up all my space and his little brother I added a feathery pattern to the body and arm arms now we can seal it all in these are some cores from a dog bag roll with some masking taped dowels to fit [Music] inside those mechanics weren't entirely ironed out this Wing shape is not working part of the problem is this nice diving motion is causing the body to travel too far away from the wings I had wanted to make this Bend shorter but the height of the elbows prevented that what if there were no elbows I could just bolt them [Music] together I've also added 56 screws it's working but this pipe is bouncing let's check the animation it's looking a lot better but this joint's still too Snappy and the whole thing bounces this design just wasn't made to handle so much weight I added this spacer here to prevent the hinge from closing too far and I close this Gap so the copper pipe can't bounce forward okay we're finally ready to [Music] fly [Music] wow that was a lot trickier than the paper version this video is going to have a part two we'll start from the beginning beginning with a prototype to a template to a working model and then re-engineered into a kit with laser cut and 3D printed Parts if you'd like to get the kit early there might be a few on my Etsy shop or you can download the template for free and I'll show you how to make it from scratch okay see you in the next [Music] one a
