QUALITY CONTROL EXERCISE - MAKING A MODEL GLIDER BY HAND

 
   

A model glider is manufactured by hand. For each of the stages listed below add a Quality Control Check. The checks should ensure that the final product is as perfect as possible.

   
STAGE 1

1. A card template is drawn accurately and then placed on the modelling making material (zepron, depron or balsa wood).
A china graph pencil or water based felt pen or even a pencil is used to draw accurately round the template.

2. A craft knife is used to cut out the shapes of the fuselage and wings. Great care must be taken as craft knives are dangerous if used carelessly.
Alternatively, a fretsaw or a fine toothed modelling saw can be used.
