Fig. 1 shows the plan of an open newelled stairs, starting from a bull-nose step at bottom, and having a short piece of rail along the top to give sufficient headroom. The dotted lines show the joist.
Fig. 2 shows the elevation, with spandril and newels. After having taken the width, height and going or run on to the rods, set up an elevation to 1½ scale, when the size of strings can be taken off; newels, length of rails and spandril can all be set out. Draw the line H H parallel to the line of nosing and 7 feet above. Keep the bottom of facia crossing over the bottom flight above this line. After having set out the stairs to this scale mark off the rods full size.
Fig. 3 shows the width rod, with the two newels marked on it.
Fig. 4 is the going rod, with newels, face of risers, joist, &c., all marked on it.
Fig. 5 shows the height rod. Mark on to this rod the two landings.
Fig. 6 shows the newels on the half-space landing. The newel A being the bottom one, runs right down to the floor, the bottom square on it being to receive the bottom handrail, while the short level rail is above this. The newel B, the top square, is to receive the top handrail, and the short rail is below it. Thus it will be seen the twining on the top newel is shorter than on the bottom one marked A.
The details will be found on the following plate.
