Figure 37. — 1769: Roubo's illustration of the brace and 

 bit differs from Moxon's only in the precision of the de- 

 lineation. Contrast this form with that of the standard 

 Sheffield version in figure 38 and the metallic braces illus- 

 trated in figures 40 through 44. From these plates can be 

 seen the progression of the bitstock toward its ultimate 

 perfection in the late i gth century. (.\ndre-Jacob Roubo, 

 L'Art du menuisier, 1769.)
