After I'd completed the Flying Cow project I had a spare cow head just lying around doing nothing. "Trophy Cow" I thought. And so, without further ado, I present this special, members only download. It fits on a single page and only takes a few minutes to do but the result is quite cute I hope you'll agree.
Print out the colour or mono version onto a single sheet of thin card (230 micron / 67lb) Score along the dotted and dashed lines then carefully cut out the pieces.
Starting from the top of the shield, fold over and glue down the tabs to make a right angled triangle. After the top, fold down and glue the two sides then the four sections of the curve.
Complete the shield by adding the hanger as shown above.
Fold up and glue together the neck.
Assemble the head and the horns
Glue the horns to the head, glue on the eyes then glue the fringe into place.
Glue the neck to the grey area on the shield.
Complete the trophy by adding the head to the neck.
Find a suitable place to hang your trophy cow.

A Flying Cow to download and make. Turn the handle on this fun papertoy and the cow flaps her wings using four bar linkages to make a the movement particually enthusiastic.
As always, members can download the parts for free at the link. Non members can download the parts for £2.50
Print out the parts onto thin card (230 micron / 67lb) Score along the dotted lines and cut out the holes before carefully cutting out the pieces.
Fold over the push rod ends and glue them down to make double thickness card. Once the glue is dry carefully cut them out.
Fold round and glue together the main push rod. Glue the push rod ends onto the grey areas.
Glue together the three section of the crank tube. Join the long piece to one of the short crank tube using one of the crank joiners. Thread the push rod end onto the longer crank tube.
Glue on the other crank joiner and crank tube to complete the crank assembly.
Fold round and glue down the tabs on the box pieces to make a right angled triangle.
Glue the two box side together.
Fit the crank into the box. This is a bit fiddly but stick at it, you'll get there!
Fit the box top into place over the push rod and glue it down.
Assemble the slider tube, slide it over the push rod and glue it to the tab in the box top.
Assemble the handle in three steps. Fold up and glue the two tubes. Fold one tube into the other and glue it into place. Roll round the long tab and glue it down.
Glue the handle to one of the crank ends. Pick one, it doesn't matter.
Fold the tabs round on the two body supports to make triangular tubes. Glue them to the top of the push rod, front and back.
Assemble the body. Glue the body support into place approximatiely 25mm from the front of the body.
Glue together the three parts of the neck.
Glue the neck into the body.
Assemble the head.
Assemble the horns.
Glue the horn to the head, glue on the eyes and glue down the fringe holding the horns into place.
Fold up the tab on the end of the wings to make a right angled triangle.
Assemble the linkage parts. Glue them to the wings so that they criss-cross as in the picture above.
Glue the linkages to the body.
Fit the body to the push rod so that the push rod lines up with the back linkage.
Glue the two wing push rod supports to the slider tube 2mm from the top. The longer of the two should be at the the front of the slider tube.
Invert the model. Glue the wing push rods to the centre linkages so that the end of the tabs touch the end of the linkage.
Turn the handle so that the push rod is at its lowest position. Lift the wings to their highest position then glue the wing push rod to the tab on the wing push rod support.
Assemble the udder. Glue the body supports in place front and back.
Glue the udders into place in the body.
Fold the legs in half and glue them together to make double thickness card, once the glue is dry carefully cut them out and glue them into place.
Finish off the model by adding the head.
Once the glue is completely dry, turn the handle and your cow should moo-ve smoothly through the air.

I've put together a flying cow model based around the four bar linkage wings. Pictures below. I'll put together a colour version with animation tomorrow.
Thank you everyone, for all the splendid ideas in the previous post. I think this mechanism will be particularly fruitful :-)

With thanks to Michael42er and Smelter, I present a slightly updated version of the nodding cow which now includes both a nodding head and swaying udders! Check out Michael42er's YouTube video of his version. Thank you both for the inspiration.
Members can download the parts for free at the link above.
Print out the parts onto thin card. (230 micron / 67lb)
There are three verions of the cow in the file, holstien, jersey and line only. Print out the version of your choice or all three for a mini-herd. Note that the second sheet in the two coloured versions has both a back and front. Print out the front, flip the card over and return it to the printer and print out the back.
Score along the dotted lines then carefully cut out the parts.
Glue the tail to the back of the body.
Fold round and glue together the head hanger
Fold round and glue together the udder hanger.
Line the end of the head hanger with the back of the body and glue it down.
Similarly, line up the udder hanger with the back of the body and glue it on top of the head hanger.
Glue together the two halves of the neck.
Glue the neck tabs to the neck hanger. Make sure there is no glue of the crease line so that the neck will move freely.
Glue the tab at the end of the udder to the udder hanger.
Make four coin parcels using offcuts of card and small 20mm diameter / 4 gram coins. UK one pence piece are perfect for the job.
Glue two of the coins to the pendulum as shown above.
Fit the other two coins between the udders so that the two udder sides stay parallel and the coins are just above the main body of the udder.
Fold the body round and glue it together.
Fold over the four legs and glue them together to make double thickness card. Once the glue is dry carefully cut out the legs.
Glue the leg stiffeners into place on the backs of the legs. Notice the leg stiffener for the front legs is the one with two crease lines. The stiffener for the back legs has only a single crease.
Glue the back legs into place making sure that they are lined up with each other and vertical. Notice that the top of the legs stick up a couple of millimeters above the top of the body.
Glue the front legs to the body. Stand the cow on a flat surface before the glue is dry and make sure that the legs are level.
Finish off the model by gluing the head to the tabs on the front of the neck piece. Line up the bottom of the chin with the end of the tabs.
Move the cow, even slightly, and the head nods and the udders swing. Charming!
Also available in Jersey Cow livery!

Smelter commented on the site that the new cow project could be improved with the addition of pendulum driven udders. No sooner said than the ever industrious Michael42eer took up the gauntlet and produces this wonderous little youtube clip. Don't miss the sound effects at the end.)
Thank you Michael42er and thank you Smelter!

>> Check out the mkII cow here! <<
A pendulum powered nodding cow for you to download, print out and make. Members can download this project for free, non-members can download the file for £2.50 at the link above.
The file comes with three variations. A line only cow for you to colour, a holstein type cow, shown in these instructions and a Jersey cow. Notice that the second sheet of the two colored cows has both a a front and a back. Print out one side, flip the card over and return it to the printer to print the other side.
Print the sheets onto thin card. (230 micron / 67lb) Score along the dotted and dashed lines then carefully cut out the pieces. This project doesn't need a sharp knife so may be particularly suited to younger people.
Glue the two neck pieces face to face. Make sure you only glue the body of the part together, not the tabs.
Glue the tail into place on the top back of the body.
Fold up and glue together the neck hanger.
Make two parcels from offcuts of card wrapped round a 20mm, 4 gram coin. I used a UK one pence piece for each parcel.
Glue the coin parcels to the end of the neck pendulum. One on each side. It is a little easier to see where the coins fit in the next picture.
Glue the neck hanger to the inside top of the body so that the long end is lined up with the end of the body. (Arrowed)
Glue the neck to the neck hanger as shown above.
Wrap the body round and glue it together so that the neck sticks out of the end.
Fold over the four legs and glue them together to make double thickness card. Once the glue is dry carefully cut out the legs.
Glue the leg stiffeners into place on the backs of the legs. Notice the leg stiffener for the front legs is the one with two crease lines. The stiffener for the back legs has only a single crease.
Glue the back legs into place making sure that they are lined up with each other and vertical. Notice that the top of the legs stick up a couple of millimeters above the top of the body.
Glue the front legs to the body. Stand the cow on a flat surface before the glue is dry and make sure that the legs are level.
Finish off the model by gluing the head to the tabs on the front of the neck piece. Line up the bottom of the chin with the end of the tabs in the position arrowed.
Once the glue is dry moving the model, however slightly, will set the head nodding. Moo!

Why did the cows cross the road? My guess, they were going to the milking parlour. I was struck, as I sat waiting for the herd to cross the road in front of me, just how rectangular cows are. They are just a big box on four legs. It turns out that a cow shaped box is the perfect place to house a pendulum.
And so, I present to you...
Pendulum powered moo-vement!
