ABSTRACT:
A system for producing precise angular measurements in order to accurately configure an object, such as a wing rib, to be fit within a cavity, such as a wing. This system includes a device for measuring the interior angular measurements of the sides of the cavity and a device for measuring the exterior angular measurements of the sides of the object to be fit therein. Once these angular measurements are made, the exterior angle measuring device is made to encompass the interior angle measuring device. Any difference in space therebetween is related to the difference in angular size between the sides of the object and the cavity into which it is fit. Appropriate size adjustment of the object can then be readily made.
