Pirate Chest

Pirate chest: a finger-jointed chest with a barrel lid of narrow staves laid over two arched ends, hand holds in the ends and a lock plate with an engraved keyhole. Each lid end is two layers glued together, so every stave has a broad edge to glue to, and the lid hangs on two leather straps glued across the back, the way old sea chests were hinged. Assembly: glue the chest, and glue each pair of lid ends together. Stand the lid ends on the chest's ends and glue the staves on one at a time from the back, keeping the gaps even. Glue two leather straps, 20 mm wide, from the back wall up over the

Grand Piano Music Box

Grand piano music box: a little grand piano that holds a wind-up music box movement. The case is a stack of frames cut to the piano's curve, the keyboard has raised black keys, and the lid lifts on its prop stick to let the tune out. The legs are crossed pairs that plug into the floor. Assembly: glue the frames in a stack on the floor and the cheeks, keys and name board at the front. Screw the movement to the floor with its key through the hole. Slot each pair of leg plates together and plug them in. Glue the two lid layers together, so the hinge screws have wood to bite, and hinge the lid alo

Kamishibai Story Theatre

Kamishibai: a paper theatre for telling picture stories. The story cards stand in a finger-jointed frame and slide out through a slot in the side, one picture at a time, while you read the words printed on the back of the card in front through the back window. Two side doors and a top door open like curtains for the show. Use 6 mm plywood or thicker so the hinge screws have wood to bite. Assembly: glue the frame. Hinge each side door on the front edge of its side and the top door on the top front edge with small brass hinges, using screws no longer than the plywood is thick.

Four in a Row

Four in a row: drop your tokens into the columns and be first to line up four, across, up or diagonally. The board is two face plates held apart by the column separators, whose tabs pass through both plates and are glued, so the board stays square and flat. It slides into the two stands, and pulling the release bar out at the bottom lets all the tokens fall out to start again. One player's tokens are walnut, the other's plywood. Assembly: glue the separators' tabs into one face plate, lay the release bar along the bottom without glue, and glue the other plate on, checking the bar still slides.

Crankie Story Box

Crankie: a moving panorama, the old storyteller's box. A long paper scroll winds from one upright spool to the other past a window, turned by the cranks on top. The window's lower edge is a skyline of hills and pines, so the foreground stays still while the scene scrolls behind it, and an open back lets a lamp shine through the paper. The spools are sized from the scroll's length and thickness. Assembly: glue the box together on the plinth, leaving the top loose. Tape the scroll's ends to the dowels, wind it on, drop the dowels through the bottom holes, then fit the top and glue a crank on eac

Desk Catapult

Desk Catapult

Catapult: a desk mangonel. A three-layer laminated arm turns on a dowel axle between two braced uprights, sprung by rubber bands from a notch on its short end to an anchor dowel behind. Pull the arm back and push the trigger peg across over it; pull the peg out sideways to throw. The arm hits the padded stop bar and the ball flies on. The peg stays in the right upright when pulled, so it cannot get lost. Assembly: glue the three arm layers into one, with the tabbed layer in the middle, and glue the cup and its ring onto the tabs. Push the uprights' tabs into the base, fit the stop bar and the

Captive sliding tile puzzle

Slide grid: a solvably shuffled sliding puzzle with a removable clear retainer. Circular finger ports let tiles slide beneath the cover while keeping them in. Assembly: glue the plywood spacer to the floor. Add tiles, then bolt the acrylic cover on with thin washers for vertical play. Undo it to change tiles.

Tilt maze

Tilt maze: roll a ball bearing from the dot to the star. Every seed draws a new maze, and there is always exactly one way through. The maze layer is stacked as many times as the ball needs, under a clear cover.

Wellspring saqiya water wheel

Wellspring: a saqiya, the animal-driven water wheel al-Jazari drew in the 13th century. Turn the ox round its walk and the draw-bar turns a peg wheel above the gear pit; its dowel pegs drive a lantern pinion at right angles, and the wheel on the same axle lifts a ring of pots out of the well and tips them into the trough at the top.

Dabble duck automaton

Dabble: a hand-cranked duck automaton on an open cam box. Three cams on a square shaft lift three dowel pushrods through the deck: as you turn the crank the duck dips its head to the engraved pond while its tail tips up, lifts its head again, then raises its wings. The pushrods are only lifted; the duck's own weight keeps them on the cams, so turn it slowly.

Peck pecking hens

Peck: the folk toy of hens pecking grain on a round paddle. Each hen's head rocks on a bolt through her body, and a string from her neck runs down through the paddle to a weight hanging below. Hold the handle and swing the paddle in small circles: the weight swings round, pulls each string in turn and the hens peck one after another, their tails bobbing up behind.

Helix Archimedes screw marble lift

Helix: an Archimedes screw marble lift. Turn the crank and a screw of 120 stacked plates, each a step round from the last on a square bar, pushes 16 mm marbles up a trough of dowels. At the top they drop onto a chute and roll back down a zig-zag track behind the screw to a ramp that feeds the screw again near the bottom.

Cascade binary marble adder

Cascade: a marble computer that adds in binary. A column of rockers on a leaning board holds a number, one bit each: 1, 2, 4, 8 and 16 from the top. A marble that meets a 0 sets it to 1 and drops into the return channel; one that meets a 1 sets it back to 0 and rolls on to the next bit, the carry. Drop a marble into the slot marked 4 to add 4; lift the bar behind to reset.

Weave pintograph

Weave: a pintograph, a drawing machine with two turning discs. The crank turns a small drive gear that meshes with both discs; the right one has a few more teeth than the left, so it slowly falls behind. An arm on a pin in each disc carries the pencil where the two arms cross, and it draws loop after loop, each a little different, weaving a cushion of lines.

Echo pantograph

Echo: a pantograph for copying a drawing larger. Four arms make a hinged parallelogram anchored to the board; trace the original with the stylus and the pencil draws it again, 1.5 to 4 times the size. Move the stylus and the pencil to the holes engraved with the same ratio. To copy smaller, swap them.

Crawl spider walker

Crawl spider walker

Crawl: an eight-legged walker on Klann linkages. Each leg is a six-bar linkage: the crank drives a connecting arm held by a lower rocker, and the arm swings the leg, held at the top by an upper rocker. Turn the handle and each foot follows a walking path, then lifts and reaches forward. The legs are phased to support the body through the crank cycle.

Lambda Chebyshev walker

Lambda: a four-legged walker on Chebyshev's lambda linkage. One square shaft turns four eccentrics a quarter turn apart; each drives a lambda whose far end follows an approximately level path before lifting and swinging back. The legs hang from those ends on flat soles. Turn the handle anticlockwise, seen from the handle side, to follow the walking motion.

Bloom expanding flower

Bloom: a mechanical flower that opens. Turn the drive ring in the middle and six couplers push six sculpted petals straight out along their radial guides, all together, so the flower grows from 34 to 42 cm across; turn it back and the petals close again.

Flight moth automaton

Flight: a moth automaton on a standing board. Turn the crank behind the board and a pin on the front disc pushes a slider up and down between two guide posts; two links from the slider rock the wings on their fixed roots, so both wings beat together.

Ascent marble lift

Ascent: a hand-cranked marble lift. Turn the crank clockwise and a pocket in the laminated wheel carries one marble up the left side, over the top and down to an opening in the shroud on the right, where it drops out and rolls down a sloping chute into a covered catch box.

Tidal wave automaton

Tidal: a hand-cranked wave automaton. Round cams sit off-centre on a square shaft, each turned a little further than the last, so as you turn the crank they lift seven fins one after another and the fins ripple like a wave.
