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.
