What reading level is On the Springing And Adjusting of Watches book?
To quickly assess the difficulty of the text, read a short excerpt:
Pure olive oil may be used with confidence. It may be heated in a wrought iron pot, which must not be tinned. The cover may have a hole in it for the insertion of a ther- mometer, and hooks on the under side from which the springs may be hung.
Springs are more liable to distortion when perfectly hard than when tempered. No explanation appears to have been given of this curious fact, but, mention of it may prevent IO4 a beginner attempting to polish watch springs before tempering.
The most usual... method of mechanical polishing is as follows : The flat faces are polished by gently pressing the tip of the finger on the spring, and moving it in a circular direc- tion on a piece of writing paper on which red stuff has been rubbed.
The spring is drawn down over a piece of wood with a conical end like Fig. 66, with a pin at the apex for the eye to go over, and the outsides are polished with a well-worn brush charged with red stuff.
The inner sides are much more difficult to polish ; but if the wire is good, and has not been raised to an excessive heat in hardening, and if the air has been properly excluded during that operation, but little polish will be needed.
