CHAPTER I 



INTRODUCTION 



In order to obtain good results in the using of tools 

 it is necessary to know their construction, how to prop- 

 erly sharpen and adjust them, and the correct method 

 of handling them. It is also essential to know how to 

 lay out and work the material or stock. Carelessness 

 or a lack of knowledge is invariably followed by a 

 failure. It is more important at first to work carefully 

 and accurately than rapidly. 



" Tools are made to be used, not abused." They 

 must be kept clean and sharp and should be nsed only 

 for the purpose intended. Wipe tliem off occasionally 

 with an oily rag or waste to prevent them from rusting. 

 Put away all tools not in use and keep the top of the 

 bench clean. Do not mark it with a joencil or scratch 

 it with a knife. Do not cut into it with the chisel 

 or allow other tools to mark or deface it. When using 

 glue, shellac, or similar materials, cover the top of the 

 bench ; or, better still, do the work on a table provided 

 for that purpose.
