So I've got the Paper Bird outline done. I now need to add some movement to complete my tweeting bird project. I think I mentioned before, I'd like to be able to drive the beak and the wings using linkages hidden in the legs. Here goes.

I'm using pull straps rather than push rods as small pull straps are easier to make, you just need to cut a strip.

The leg has a knee in the middle, to transfer the pull round the corner I have made a small bell crank.


The bell crank fits inside the leg and the two connected tendons protrude out of each end of the leg.


And there it is fitted to the box top. It works a treat! Next step, make two, one leg to control the beak, the other for the wings.

Download Paper Bird

These simple-to-make paper birds are a delightful decoration to brighten up any house!

The parts are available at the link for everybody to download for free. Included in the parts file is a special discount code that gives you 10% discount on standard membership and 20% discount on membership plus! The special offer is valid for use until the end of August 2014. I hope you enjoy making these paper birds!


Print out the parts onto thin card. 230 micron / 67lb is ideal. Score the dotted and dashed lines and cut along the solid lines before carefully cutting out the parts.


To make the bird extra colourful, print it out twice onto complementary coloured card. Cut out both sets of parts then use the legs, feet and beak from one colour and the remaining parts from the other colour. Once you are done you can make a matching, complementary bird with the remaining set of parts.


Glue one side of the beak to the head lining it up between the two dots. (Arrowed)


Glue the other half of the body to the other side of the beak. Don't glue anything else, just the beak. Make sure that the body halves are lined up.


Glue the body top into place. Start with the first set of tabs lined up with the bottom of the beak. (Arrowed)


Finish gluing the body top into place lining it up with the top of the body sides.

Glue the two wings to the tabs on the side of the body.


Fold round and glue down the end of the body inner to make a triangular tube.


Glue the end tab of the body inner to the front underside of the body top. Glue the sides of the body inner into place so that it slopes down at forty five degrees.


Assemble the legs as shown. The knee should be at ninety degrees.


Glue the feet to the legs.


Glue the legs to the body inner. Use the grey glue areas for alignment.


The completed paper bird! Try making a flock of different colour birds or try making birds from pattern printed papers.

I'm delighted to say that I have taken back the reigns at www.flying-pig.co.uk

Flying Pig was my first website and is still a source of pride. It is the place where you can buy many of my printed kits and books. Over the last couple of days I've updated the website, focusing it exclusively on my own designs, I've reduced the prices of the kits and dropped the price of shipping to only £2.95 for any order, anywhere in the world.

Thanks to Peter Dean in HK who has so ably run the website these last few years. I wish you every success with all your future endeavours.

As a final cherry on the cake I've added the Make Your Own Animation Machine book to the site. It is probably cheaper on Amazon but hey, these one's are signed :-) You can visit the website here.

Time to convert this paper bird from rough paper outline version to digitised version.



The first step is the hardest, or at least the most unnerving. I need to take a scalpel and scissors to the model and cut it into pieces ready to be scanned.

 

I've scanned both body sides, one showing the outside, the other showing the inside so that I can see where the internal pieces were glued.

The scan is dropped into Illustrator where I carefully trace the pieces.

The moment of truth, does it go back together? Yes it does!

Here you can see how the legs fit into the body.

Next step is to make some minor tweeks then add the lower beak and wing linkages.

Before I start, can I just ask, to the person who sent in the picture with the Escher Tiles, please could you resend it? It looked great and now I can't find it anywhere! Thanks

I've been tardy posting Michael42ers wonderful videos. Here are three for your delight!

Running man , featuring the double crank box.

Michael's version of the twitter box (I'm back to working on the bird now after my T.Rex diversion)

Finally, another model featuring the double crank box. Nice work Michael! Thanks for sharing!

Turn the handle on the Ski Rex and watch our prehistoric friend indulge in a bit of cross country skiing!

This model is actually a mash-up of the double crank box model and the pose-able T. Rex with added skis poles and a bit of colour! I've put all the parts into one file in both coloured and uncoloured form. If you are a member you can download the parts for free at the link. Non-members can download the parts for £2.50



Let's get started!

Print out the pages onto thin card. (230 micron / 67lb) Score along the dotted and dashed lines then cut out the holes before carefully cutting out the parts. There are six sheets in this model.


Start by making the T. Rex

Glue together the four parts that make the body.


Assemble the head upper, gluing the head inners into place (Deep red in the picture) make sure the tabs on the head inners are folded inwards as shown.


Glue together the tongue support.


Glue the tongue support into the assembled lower jaw.

Curve the tongue round and glue it to the tongue support.


The arms and legs are double thickness card. Fold them over and glue them down leaving the tabs unglued. Once the glue is dry, cut out the parts.


Fit the legs into the body. Glue one of the large disks to the leg tabs. Make sure that the leg is free to move as the glue dries.


Repeat this process with the arms. Use the small disks to secure them.


Thread the tabs from the head inner through the holes in the lower jaw and then into the body. Glue the remaining disks over the tabs making sure that the head and jaw can move.


Glue on the eyes and the feet to complete the T. Rex. Set her to one side as you start on the box.


Assemble the two short crank pieces.


Assemble the long centre crank piece.


Fold up and glue down the four push rod ends to make double thickness card. Once the glue is dry cut out the hole and then cut out the pieces.


Roll round and glue down the four pins lining up the edges with the end of the grey area.


Assemble the push rods. Glue the two push rod ends into place and thread the 'Centre' pin through them. Make sure the pin is free to turn.


Glue the long centre crank piece between the two pins. Make sure both push rods are the same way up.


Complete the crank assembly by adding the two shorter crank pieces and the two pins. Make sure everything is as square and lined up as possible.


Fold up and glue down the tabs at the side of the box-top and box-bottom to make a right angled triangle section.

Fit the box-top stiffeners into place next to the slots in the box-top.


Fold round and glue the flaps on the box end to make equilateral triangle tubes.


Glue the top of the box end to the box-top. Glue it to the end opposite the long slots.


Assemble the two slider bars and slider tubes.


Glue the two slider bars as centrally as possible in the two slots.


They should look like this from the top. The slider tubes should be free to move back and forth.


Fit the crank assembly into the box end with the tabs on the push rods facing downwards.

Glue the tabs to the slider tubes. The crease on the tabs should line up with the centre of the slider tubes.


Fit the other box end and the box base into place to close the box.


Fold in and glue down the end flaps to make triangular tubes.


Fold in and glue down the flaps at the other end of the box onto the inside walls of the box.


Assemble the handle in three steps.


Glue the handle into place to complete the box. Once the glue is dry you can check that it is working properly by turning the handle. The slider tubes should move back and forth in oppoite directions to each other.


The skis are made from three layers laminated card.

Glue the three layer of card together. Curve the ends upwards before the glue dries. Once the glue is dry they will maintain its shape.

Let the glue dry then carefully cut out the curved end of the ski and cut off any excess card.


Two skis ready to go!


The skis glue onto the tops of the slider tubes. Turn the handle so that the two slider tubes are lined up with each other in the centre of the slider bars. Glue the two skis carefully into place so that they are centred on the box top. Make sure that the skis don't get stuck onto the box top. Rock the handle back and forth a little as the glue is drying to make sure everything is moving freely. Let the glue dry completely before moving on to the next stage.


The T Rex is glued to the ski by the front of the inside toe only. This allows her to lift her ankle as she skis. With the heel roughly five millimetres from the end of the ski glue the toe down onto the ski.


The poles are glued to the underside of the ski. They must not be glued to the box top. Assemble the two poles. Glue the tab on the end of the pole to the underside of the ski next to the star. Glue the circle onto the underside of the ski so that it is centred under the pole.


Glue the dinosaur hands to the top of the poles


Let the glue dry then turn the handle to see your T. Rex ski. Ski Rex indeed!

Further to my previous post about Mr Cool's video. Shamelessly stealing his idea I put together a Too Much Coffee character printed at 80% full size and mounted it on a double crank box. While I was trying this out I noticed a T.Rex waiting around on my desk so I mounted her on the other double crank box that I had.

Both worked rather nicely! Even though they have a slightly shuffly gait I can certainly recommend them as projects to try! Thanks Mr Cool!

Check out both of the models on Instagram below.

Another fabulous mash-up from the every creative Mr Cool! This time he has taken the double crank box and added "Too Much Coffee" a project from a while back. The result is our coffee drinking hero shuffling across the box top as if in search of his frst coffee of the day.

Looks to me like a mash-up that I should make into a kit! Thanks Mr Cool!

The other day I had an email asking permission to modify one of my projects. Anneli from Berlin wanted to modify the Flexiphant to make a mask for her daughter. I was intruiged and happily gave permission ( Feel free to modify my designs everyone, I just ask for a link back to the site for anything that goes on the web)

Anyway, a couple of weeks passed and I received thse fantastic pictures of the competed Elephant mask.

Eight year old Mika shows off the elephant mask in action. She was leading elephant in the school play "Welcome to the Jungle"

Well done Mika! And thanks for sharing the pictures.

 


It works!

Pull the hidden tab and the truck raises.

Double crank mechanism. Turn the handle on the side of the box and the two pads on the top of the box move back and forth in opposite directions.



Make this project as a way of understanding mechanisms or as the starting point for your own character based paper automata.

Members can download the parts for free from the Add to Basket link at the top of the page. Non-members can download the parts for £2.50

Print out the parts sheets onto thin card. (230 micron / 67lb) The design has no colour in it. To make a colourful model print it out on some pre coloured card. Score along the dotted and dashes lines then carefully cut out the holes before carefully cutting out the parts.


Fold in the box top and box bottom and glue down the side flaps so that they make right angled triangles.


Glue the three box top stiffeners into place. Glue the flaps from the sides of the slots back onto the box top stiffeners.


Glue together the two slider bars and thread the two slider tubes into place. Make sure that the slider tubes are free to move back and forth along the length of the slider bars.


Glue the two slider bars to the underside of the box top so that they are exactly centred in the slots.


Make sure that the slider tubes are free to move back and forth.


Roll up and glue the various pins. Use the arrows and grey areas to make sure that the edges are glue down in the correct place.


Fold over, glue down then cut out the four crank rod ends. Glue two crank rod ends to each push rod and thread the 'Centre' pin into each one.


The completed push rods.


Fold up the long centre crank...


....and glue down the ends as shown.


Assemble the two other cranks in the same way.


Assemble the handle in the three steps.


Join the two push rods together by gluing the pins into the long crank section. Make sure that the two push rods are the same way up, tabs to the bottom.


Finish off the crank assembly by gluing on the two shorter crank pieces and gluing the pins into place.

Make sure that the push rods are free to turn on the pins as the glue dries.


Glue the ends of the push rods onto the bottom surface of the slider tubes. The crease on the tab should be roughly in the centre of the slider tube.


Fold round and glue the triangle sections on the sides of the box end.


Glue the box end to the box top. Make sure you glue it to the opposite end of the box from the two slots as shown in the picture.


Thread the crank assembly into the box end and glue down the box end sides.


Fit the other pieces of the box into place then fold them round to close the box.

Fold in the tabs and glue them to the inside wall of the box.


Fold in the two tabs at the other end of the box and glue them back to back to make a triangular tube.


Finish the model by gluing the handle into place.

Now that you have completed your double crank mechanism it is time to think about how you could add a character to the top of the box. What will you make? A cross country skier? Michael Jackson moonwalking? Two pirates swabbing the deck? It's over to you!
