The tracing paper or velograph sheet would be placed on the Ozalid sheet stuck onto the drawing board and the air brushed away. Brushing charged the surface, and the film would then be taped taut (but released at the end of each ...
A typical construction of a ratchet-based mechanical pencil. A mechanical pencil or clutch pencil is a pencil with a replaceable and mechanically extendable solid pigment core called a "lead" / ˈ l ɛ d /.
