The owl model is the latest in the projects I'm highlighting from the Brother International site. Turn the handle and the mechanism turns the head back and forth almost all the way round.

Everyone can download the model for free from the Brother International Creative Center. I'm hope you enjoy this updated version of the owl model!

The ever inventive Michael42er has uploaded a new video onto his YouTube channel. This time Michael has turned his attention to the new Shark Attack model modifying it to include an underwater view of the terrifying circling sharks.

Thanks Michael, I love it!

Essential Mechanisms™

Mesh Gear Type 2

Turn the handle on the side of the box and the large disk on the top of the box revolves. The type 2 mechanism features a fixed tube to which stationary objects can be attached making it possible, for example, to make a model featuring a dog chasing round a stationary tree.

 

Paid subscribers can download the parts file from the link for free. Non-members can join in the fun for just £2.50.

Once you have downloaded the file, print the parts out onto thin card (230 micron 67lb) I have used coloured card in these instructions to create a colourful model. You can use coloured, white or patterned card for yours.

Score along the dotted and dashed lines and cut out the holes before carefully cutting out the parts.


Fold the gears in half and glue them down to make double thickness card


Once the glue is dry carefully cut them out.


Roll up and glue the three axle tubes lining up their edges with the points of the arrows.


Glue the gear axle tube to the gear then glue the 9mm diameter tube into place inside the square tube. Line up the end of the axle tube with the end of the square tube.


Glue the pinion gear to the pinion gear axle lining it up with the grey line.

Thread the 8mm tube into place lining up the square tube between the two grey lines and glue it into position.


Fold round and glue together the base. Don't glue the ends yet.

Glue the spacer into place as shown reaching inside to press the tabs down firmly.


Glue down the base ends.

Fit the 7mm tube into position.


Glue the box sides to the base using the small arrows for alignment.


Top view of the base with the sides glued on.


Glue one edge of the front to one of the side edges closest to the rectangular hole in the box side.


Glue the other side of the front into place.


Drop the large gear into place onto the vertical shaft. It should be free to turn.


Fold up and make the pinion support.

Glue it into place between the two sides with the hole facing towards the front.


Fit the pinion into place between the pinion support and the box front as shown.


Glue the box back into position.


Thread the box top down over the vertical shafts and glue it down to the box.


Fold in and glue down the tabs at the back.


Assemble the handle in three steps.


Glue the handle to the pinion shaft.


Thread the disk inner into the disk and glue it down.


Glue the disk to the outer rotating vertical shaft.

If you choose you can add the square section piece to the inner tube as a place to attaching model parts in your design. This part will be stationary.


Turn the handle and the disk rotates. The gear reduction is roughly 2.5:1

Use this an experiment in pure mechanism or as the starting point for your own designs.

Paper Unicorn!

Rock the unicorn back and forth and she stretches out her head and neck using a simple linkage concealed beneath the body.

I designed this model for Brother International Creative Centre, it is available to download for free here.

It is a fairly straightforward model being classified as medium difficulty on their website. I hope you enjoy it!

Shark Attack!

Turn the handle and the sharks circle menacing around the boat. Duuh duh! Duuh duh!

This model uses a variant of the mesh gear essential mechanism which I will shortly be releasing as a stand alone project.

Paid subscribers to robives.com can download the model for free at the link, thanks for your support! Non-members can download the parts file for £2.50


The model comes in both coloured and non-coloured versions. Print out the one you choose onto thin card. (230gsm/67lb is ideal) Score along the dotted and dashed lines and cut out the holes before carefully cutting out the pieces.


Fold over the gears to make double thickness card and glue them down.


Once the glue is dry carefully cut them out.


Roll up the three axle tubes carefully lining up the edges with the arrows as shown.


Fit the pinion gear into the pinion tube lining it up with the grey line and gluing it into place with the tabs.

Fit the 8mm tube into the square tube lining it up between the two grey lines.


Fit the gear shaft into the large gear and thread in the 9mm axle tube so that it lines up at the bottom face of the gear.


Fold round and glue the base piece leaving the ends unglued. Fit the base spacer into position. The end of a chop stick can be handy for reaching inside the base when gluing the tabs on the spacer down.


Glue closed to complete the base.


Fold up and glue the box front and box back. Note that the long triangle tube is a right angled triangle.


Crease the score lines on the box sides in preparation for assembly.

Note the four grey alignment arrows, arrowed in the picture.


Glue the two sides to the base between the alignment arrows.


With the two sides glued into place, glue and push home the 7mm tube.


Fit the large gear over the 7mm tube. It should be free to turn smoothly.


Glue the box front to one of the box sides. Make sure you glue it to one of the edges closest to the rectangular holes in the side pieces.


Join the box front to the other box side.


Fit the axle support between the two box sides making sure that the circular hole is facing towards the front of the box.


Thread the pinion gear into place between the box front and the axle support.


Glue the box back into place.


Thread the box top down over the vertical axle tubes and glue the top into place.


Assemble the handle in three steps as shown.


Glue the handle to the pinion shaft.

Once the glue is dry turning the handle should turn the outer of the two vertical shafts. The centre vertical shaft should remain stationary.


Glue together the rotating disk and tube.


Make up the shark fins from double thickness card. Once the glue has dried carefully cut them out.


Glue the fins to the disk. The wake pattern on the disk should be behind the fin.


Fit the rotating disk to the outer vertical tube. Turn the handle and test that the disk turns properly.


Assemble the boat stand and boat stand inner.


Fit the boat stand to the inner vertical tube.


Assemble the two parts of the boat.


Fit the boat onto the boat stand, you won't need to glue it down.


Assemble the boater man from double thickness card.


Glue him into the back of the boat to complete the model.

Turn the handle to see the sharks circle menacingly round the boat!

I was recently commissioned by Brother International to produce a set of paper projects for their website. I'm delighted to say that they are now available to download for free! There are six models in total section divided into easy, medium and hard.

The crab model is one of the hard models. Don't worry it's not so hard and it is definitely worth the effort! Turning the handle drives a scotch yoke that will be regulars to this site. The scotch yoke in turn drives the crab claws raising the arms and clicking the claws together.

Everyone can download the crab model for free here of the Brother Int. website.
