Practical 3

During practical 3 we were introduced to different ways of joining or molding cardboard to the desired shape. Such Joinery includes things like slots, tabs and slots, brass fittings and zip ties. some ways to mold cardboard to the desired shape include scoring, bending and L-bends.

During the practical we were tasked to make our own visual board of different attachment and molding technique. Our group were pretty ambitious and decided to make a house to represent some of the different attachment and molding technique. However, due to poor planning and poor teamwork, we were unable to make the house to a satisfactory level and hence was unsatisfied with our final visual board.

The types of attachment technique we used to make the house includes gusset plates for the roof, Score & bending for the walls of the house and slots for the tree shown below.

After the practical we had a little assignment which is to assemble a unicorn via a DIY kit.

After popping out all of the parts from the DIY kit it is first laid out on a table before assembling. Whilst assembling it, some of the attachment technique includes techniques like tabs & slots for the main body and head, Slots for the tail, horn and mane.

After assembling the body and head separately they were then to be connected together via tabs & slots.

The wings slightly bent according to the outline for some "texture" to the wings.

To make the wings move, holes were cut into the wings where a stick was placed through. This stick would then be moved back and forth to create the movement of the wings. The wings would be held to the stick via friction and hence will not dislodge.

However, for an automated way to allow the wings to move a cam and follower system will be used. The shaft/ follower will be connected to the wings and will be returned to place using springs. a motor will be connected to the cam and hence will slowly turn and rotate the cams to emulate the the flapping of the wings.
