About This Book

A practical trade manual that presents step-by-step methods for laying out, cutting, and assembling stairs and handrails. It begins with elementary geometric problems and stretch-outs used to form curves and easings, then explains how to transfer site dimensions onto rods, set out risers, goings, strings, newels, landings and winders, and apply the steel square for accurate profiles. Plates and worked examples illustrate full-size layouts, recommendations for rise-and-run proportions, and a tested square-section and falling-line approach to handrailing, with detailed workshop techniques for cutting, fitting and joining components.

PLATE. 5.

PLATE V.
DETAILS OF CONSTRUCTION.

Fig. 1 shows the top rail of spandril, with the tenon cut ready to go together.

Fig. 2 is the middle rail tenoned and haunched ready to go together to fit into the stile.

Fig. 3 shows the other end of the same rail ready to go into the top rail.

Fig. 4 shows the bottom rail tenoned ready to go into the stile against the newel.

Fig. 5 is the same rail tenoned ready to go into the top rail under the string.

Fig. 6 shows a part of one panel with the moulding. To cut the moulding in, bisect the two angles as A B and C D; this was shown on Plate I. Make cuts in the mitre, cut to A B and C D, and cut the mitres to it. In putting the spandril together, put all muntings, rails, panels, top rail, bottom and middle rails first, and the stile against the newel last.

Fig. 7 shows a part section enlarged of the top rail of spandril, string of stairs and capping.

Fig. 8 shows a round-ended step. This is got out in three thicknesses, as shown at Fig. 9. This block is prepared as shown; the riser is cut to the thickness of a veneer, it is glued and screwed at the back, is well glued, brought around and well wedged and screwed as shown; the scotia is glued and screwed to the block, and the tread is well glued and screwed from the bottom. The newel is mortised into the step diagonally, as shown.

Fig. 10 shows the elevation of the trimmer at the top.

Fig. 11 shows the plans of the trimmer, with wedge and method of jointing.

Fig. 12 shows the section of newel and a part of door, frame and spandril.
