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. To find the points for pins to describe a curve parallel to A C B Set off from C to P equal B N from the point P as a centre, with S N as a radius, describe arcs cutting the major axis in the points 4 and 5 place pins and describe the curve required. Fig. 2 exhibits a plan and elevation of handrail at the starting. To find the easing and points to bore for balus ters Set up from 2 to 3 on the pitch-board, equal the differ ence in the heights of newel post and short baluster square over for the newel cap mark from the pitch-board for the point to bore for baluster. T 0 continue the height of rail at the starting to its termin ation, care should be taken to measure the rise from the points to bore for balusters, as shown by the dotted lines.
