Under this head I purpose showing a few stair parts things not generally included in works of this kind, but which will be found very useful to the general workman as well as to the specialist in stair-building.
Stair Parts Fig. 88, 89, 90 & 91 (clockwise from left to right)
The illustrations shown in Stair Parts Figs. 84 to 91, inclusive, exhibit a number of different designs for stop chamfering. These will be found useful in determining the style of step for chamfering the corners of a stair parts newel post, and in many other instances as well. Some of these chamfers and stops are quite elaborate and will require considerable labor to work them out in good form; particularly is this true of Stair Parts Figs. 86 and 89, as one has a concave and the other a convex surface, and Stair Parts Fig. 89 has an ornamental termination.
Besides these styles of stops there are many others, the simplest of which is just a bevel ending of any pitch and the ogee ending, and several others of which nearly every workman is familiar.

The illustration shown at Stair Parts Fig. 92 gives the method of obtaining a reduced pattern for a bracket as required for the ends of winders Upon the top edge of the bracket used for the flyers describe an equilateral triangle. Divide the contour of the bracket into a number of parts, and draw lines from divisions perpendicular to the top or base of the triangle. From these intersections draw lines to the apex of the triangle. Next mark upon the sides of the triangle, from the apex, the length of the bracket required. Join these points by a line, a a, which is parallel with the base, and upon the points where the line cuts the, lines drawn to the apex, erect perpendiculars; make them equal in length to the corresponding lines drawn on the original bracket.
The eight illustrations shown in Stair Parts Fig. 93 give brackets and sections of handrails of various kinds, and is offered as a supplement to the page of stair parts handrail sections shown in part three of this work. In the examples given the centers of the curves forming the handrails are given, and the sizes of the rails are marked on the sections in two instances. The stair parts numbers 5 to 8, inclusive, show patterns for brackets which may be made to suit almost any style of stairs. Other patterns will be found illustrated in previous pages of this work in connection with examples of platform stairs.

Tables
The following tables which are taken from the Builder and Woodworker, but which I believe were first prepared by The California Architect, will be found very useful to those "figuring" on the run and rise of stairs. The spacing of the lines of figures into groups aids the eye in following the direction to the final point.
Directions: In the column beginning with the rise of step desired, find. the height of story from top of floor to top of floor, then follow this line to the column under risers, which gives the number of risers. In the column under "treads" find the number of risers, less one, and on this line under the column of width, of tread will be the length of run.
