Turn the handle on the side of the box and the vertical shaft rotates back and forth. Use this mechanism as the starting point for your own character based designs or as a way of learning first hand how mechanisms work.

Look out for the owl model using this mechanism coming soon.


Print out the parts onto thin card. You will also need some normal copier paper to make the paper straps. Score along the dotted and dashed lines and cut out the holes before carefully cutting out the parts.


Fold up and glue the side tabs on the box to make right angle triangle tube sections. Fold round and glue down the other side to complete the base.


Glue together the two box sides.


Fit the base into the box


Fold in and glue the four tabs to the inside walls of the box. Make sure everything stays as square as possible.


Assemble the hinged plate as shown.


Make up the two crank ends from double thickness card.


Glue together the push rod and glue on the two crank ends.


Roll round and glue the four paper tubes accurately lining up the edges with the arrows.


Thread the second-to-shortest tube into the crank ends.


Assemble the two crank pieces


Finish up the crank pieces and glue them to the axle.


Fit the shorter of the two remaining axles into the crank gluing them fully home in the square tubes.


Fit the crank into the box using the picture above to help with orientation. (Note especially which way up the push rod is.)


Glue the hinged plate to the back of the box.


Glue the push rod tab to the front of the hinged plate.


Glue the stop to the vertical shaft.


Make the handle in three steps.


Glue the handle to the crank.


Cut two paper strips 5mm x 100mm from ordinary copier paper. Glue them to the grey areas on the vertical shaft.


Wrap the two straps twice each round the shaft, one in each direction.


Add glue to the grey areas on the locater plate.


Place the vertical shaft over the green line on the locater plate. Pull the two straps tight and glue them onto the glued area. Cut off any remaining paper.


Assemble the triangular push rod and glue the back of the locater plate onto it.


Fit the vertical shaft into the hole in the bottom of the box.

Glue the tab on the end of the triangular push rod to the hinged plate.


Complete the model by gluing the box top into place. Once the glue is dry, turn the handle and the vertical shaft will twist back and forth.

Next step, design a character to go with the mechanism.

Print out the parts onto thin white card (230 micron / 67lb) Score along the dotted and dashed lines and cut out the holes before carefully cutting out the parts. The construction of this model is basically the same as the Rotating Reciprocating Vertical Shaft model and the Guard Dog model combined. It is supplied in both coloured and non-coloured versions.


Fold up and glue down the tabs to make right angled triangle tubes.


Glue together the base box. The picture shows it upside down.


Make the two cams from double thickness card.


Slide the two cams onto the longer square shaft lining them up with the grey lines. Notice that they are rotated by one hundred and eighty degrees from each other.


Glue together the two box sides.


Fit the box base into place. Glue the four tabs onto the inside walls of the box.


Assemble the handle in three steps as shown.


Roll round and glue up the axle tubes lining up the edges with the arrows.


Fit the shorter axle into the cam tube.


Glue the drive plate to the shorter square tube, lining it up with the grey line. Slide the square tube onto the longer axle sliding it into place between the two grey lines.


Fit the drive shaft into place in the box.


Drop the vertical shaft into place.


Fit the box lid over the vertical shaft and glue it down.


Finish the box by gluing on the handle. Turn the handle and make sure that the vertcial shaft turns back and forth.


Glue together the body of the dog. Glue the front legs to the grey areas.


Assemble the back legs.


Glue the back legs to the grey circles on the side of the body.

Download Display Gears

Four interlocking gear wheels in a display case. Art and engineering in perfect harmony.

This project is also on Instructables

The parts of this project are cut out from three millimetre plywood using a laser cutter. In this case, an HPCLaser 3050.

The plans for making this project are available for everybody to download for free. As well as the plywood you will also need a piece of dark coloured paper as a background and a sheet of one millimetre thick clear acrylic for the front of the box. One final addition, you will need three pieces of six millimetre wooden dowel. Two of them twenty four millimetres long and one eighteen millimetres long.

 


The parts file is divided into two pages. The file is a pdf. As different laser cutters use different file formats I leave it to you to convert it to a format suitable for your machine.


The HPCLaser in action cutting out the parts.


All the parts apart for the dowel pieces cut out and ready to go. The blue piece is the clear acrylic front with its protective film still attached. Having cut out all the parts follow the instructions below to assemble the gear display.


Glue together the two eighteen teeth gears. Make sure that they are aligned precisely.


Glue the outer ring to the thirty eight tooth gear as well as the centre hub. Again, make sure you are as accurate as possible with your alignment.


Glue the eighteen toothed gear to the hub. Use a spare piece of dowel to make sure the holes are lined up accurately.


Assemble the twenty two toothed gear as shown using the pentagon hub.


The thirty toothed gear has no hub. Carefully glue the secondary gear ring in place making sure that the teeth are accurately lined up.


Glue together the three base pieces and fit the two longer dowels into place tapping them home with a hammer if necessary. They should be a tight fit and should not be free to turn.


Fit the various spacers into place as shown in the picture.


Glue the eighteen millimetre long dowel into the knurled gear as shown. Make sure that it is sitting accurately square as the glue dries.


Glue the dark backing paper into place. This paper provides contrast with the gears making them stand out visually.


Fit the knurled wheel through the remaining hole in the base plate. It should turn easily in the hole. Fit the small gear into place on the dowel so that it just touches the spacer on the base. It should turn easily via the knurled wheel.


Drop the largest gear onto the dowel. Check that it turns freely via the knurled wheel.


Drop the final gear onto the remaining dowel. Fit the remaining ring over it so that it holds the gear down but still allows it to turn.


Fit together the five main pieces of the frame. Use glue if you need too.


Drop the acrylic front into place inside the box. Glue the two stops into place to hold the acrylic in position.


The finished front cover.


Fit the cover over the gear to complete the project.

An intermittent rotation mechanism for you to use in your own designs. Download and make the parts then add your own character.

Members can download the parts sheets from the link for free, non members can join in the fun for £2.50

Print out the parts onto thin card. Use coloured card or one of the pattern sheets from this website to make your model more colourful.

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


Start by putting together the base. Fold up the side tabs and glue them down to make right angle triangle tubes.

Fold the rest of the box and and glue it down.


Make up the drive plate from double thickness card glued together.

Glue on four of the assembled stops onto the grey areas.


Glue the fifth stop to the underside of the box so that it is roughly 5mm from the edge of the box and facing in the direction shown.


Glue together the three parts of the box then fold them round and assemble the box.


Roll up the two drive pins and glue then down accurately using the grey areas and arrows for alignment. Glue together the two drive shafts.


Slide the vertical pin into the vertical shaft with the end with the grey line toward the chevron end of the drive pin. Slide it into position so that it is between the two grey lines.

Fit the drive plate into position lining it up with the grey line and gluing down the tabs.


Fit the drive into the base. It should be a loose, easy fit.


Fit the box over the top and down onto the base.


Glue in the four tabs onto the inside wall of the box.


Assemble the horizontal drive cam.


Put together the handle.


Fit the horizontal shaft into place between the two holes in the box sides then push the pin through the the drive shaft and out the other side.


The drive shaft should look like this.


Complete the model by gluing the handle to the drive shaft.


You can fit the arrow if you like so that you can see the vertical shaft turning as you turn the handle. Over to you now to design your own character!

The Love Boat.

Turn the handle on this paper animation and the enthusiastic rower delivers his chocolate candy gift to your True Love.

This delightful model is driven via an interesting crank and linkage mechanism. The download comes in both coloured and un-coloured versions and can be easily adapted to add your own rowing character.

Members can download this project for free thanks for signing up! Non-members can join in the fun for £2.50


Print out the three pages onto thin card. 230 gsm / 67lb is perfect for the job. Score along all the dotted and dashed lines and cut out the holes before carefully cutting out the parts.


Make up the two crank ends by folding over the card and gluing it down to make double thickness before carefully cutting out the parts.


Roll up the three crank pins gluing down the ends as accurately as possible.


Make the push rod. Glue the cranks ends to the push rod and fit the longer pin through the holes.


Assemble the two crank pieces.


Glue the crank pieces to the centre pin lining them up as accurately as possible with each other.

Glue the other two pins into place.


Assemble the linkage. Glue it to the push rod so that the tabs are touching the tops of the crank ends.


Glue the oar holder into place.


Fold up the tabs on the box to make triangular tube sections.


Join the two box pieces together at one end and glue on one end of the box top.


Thread the crank pins through the holes in the side of the box and the push rod up through the hole in the box top. Glue the box top stiffener across the width of the underside of the box top lining it up with the edge of the long hole


Fold the box round and glue it closed. Glue the end of the linkage to the end of the long hole as seen in the picture.


Glue together the two boat sides.


Glue the boat to the box top.


Assemble the two oars and glue them to the oar linkage.


Assemble the seat.


Glue the seat into the prow of the boat using the long tabs to determine the height.


Make up the rowlocks with double thickness card and cut them out.

Glue them into the side of the boat between the two small black lines.


Glue the rowlock tops into place loosely constraining the oars.


Fit the rower into the boat. His waist crease line should be approximately five millimetres from the back of the seat. Glue his feet to the deck and his hands to the oars. He's going nowhere!


The box has a cut out at the bottom front so that it clears the linkage. Fit the base into place first then join the two sides together.


Complete the box but don't glue down the lid.


Glue the box into the boat with the cut out facing towards the rower. Add a chocolate and close the lid.


Set your rower to work delivering his gift to your True Love!

Download Owl Box

The shape of the Owl Box is inspired by a papertoy batman I came across whilst exploring the many and varied pages of Pinterest. I can't find it again so I'm afraid I can't give credit where it is due. That said, lets get on and make this simple but delightfully cute owl!


I started out by printing out the Owl onto a sheet of thin card (230micron/ 67lb) then printing a page from the Polka-dot Pattern download on the reverse. The polka-dots gives the inside of the box a nice finished feel. I then set the paper aside to let the ink dry completely before following these few steps to construct the owl box.

Score along all the dotted and dashed lines then carefully cut out the parts.


Pre-crease all the dotted and dashed lines. Note that the dashed lines are hill folds and the dotted lines are valley folds.


Fold up and glue the open topped box base.


Glue the two feet to the base.


Fold round and glue together the head part into a square paper tube.

Fold in the top front and back to make the two "ears"


And that's it! The head acts as a box top. Fill your owl with candy and give it to a friend.


Tu-whit Tu-whoo!

Here's as simple yet attractive gift box to cut out, make or modify. If you are a member you can download the parts for free at the usual link. Thanks for signing up!

Print out the parts onto thin card (230 micron / 67lb) Notice that the coloured version is printed on both sides. Print out one side, flip the card over and return it to the printer to print out the back. Once the glue is dry score along the dotted and dashed lines then cut out the single part that makes up the box. Dashed lines are are hill folds, dotted lines are valley folds. Pre-crease along the fold lines before folding up the box.


Fold the corners inwards then fold the box top over. Hook the tabs into the slots to hold the box shut.


There you have it! Make a couple of small holes in the lid and add a string handle if you are feeling adventurous. Use the gift box to give a present to someone special in your life!


This paper treasure chest uses the same basic design but with the sizes changed slightly.

It's perfect for storing your dubloons!
