Handcraft in Wood and Metal [PDF ebook] 
A Handbook of Training in Their Practical Working for Teachers, Students, & Craftsmen

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The general impression in the past has been that any attempt at freehand curves or decoration in models necessarily means neglect of the mechanical side, but this does not follow according to the authors experience, and they would deplore the acceptance of this idea. The main feature of handcraft work after the early stages is individual effort on the part of the pupil, which adds to the interest and value of the subject as a whole. Much has been said upon correlation in handcraft. In well directed handcraft correlation is inevitable. Thinking and doing must perforce be linked together, and when this is done in the class or craft, room it must work toward a better general education.
