Flaring Seat Corners Part 2
Then take the length of line 1, and lay off from the B on D, and draw the line L from the point of S, so as to intersect with D at the point on D, the exact length of the line 1.
The next step is to lay out a draft of the work, which may be done as follows:
Set the bevel by line 2, Fig. 211, and place the stock against the bottom edge of the board; for the back, mark across the side of the board. Then set the second bevel by line 8 of Fig. 211, and placing the tongue or blade on the side, make a mark across the edge. Next take the first bevel, place it on the mark on the edge, and mark the opposite side. Measure the length from outside to outside required at the bottom on the gauge mark, which was made for building the bottom edge, and lay out the same as the first end. Proceed in the same manner for the ends, using the bevels set by lines 2 and 3 of Fig. 212. After the work has thus been laid out and the joints cut, bevel off the bottom edge a little scant, so that the parts will stand in, say a quarter of an inch in the width. The effect of this is to hold the joints close when the work is put together.
To get out the blocks for the corners, set the bevel by line L of Fig. 213. For the cut on the bottom ends, set one bevel by line 2, Fig. 211, and the other by line 2, Fig. 212. This operation will form a corner, as shown in Fig. 214. To make a corner as shown in Fig. 215, when laying out the pack and end, make a mark on the inside of the bevel, as line 1, Fig. 216. After the miter is cut, gauge the dotted line V. Take the corner as drafted in Fig. 213, and place the line P on the line B, as shown in Fig. 217. Other lines of the first corner, same as corresponding letters, show position.
Next make line 2 of Fig. 216 at right angles with the gauge line to the corner W. Take the length of line 2 and add on to line D of Fig. 217, as shown above the first corner. Next make line 3, Fig. 216, at right angles to corner of miter marked W. Take the length of line 3, and mark down on lines B and L of Fig. 217 the same distance. Strike lines from the points thus obtained upon B and L, to mark of height raised on line D. Next cut the second bevel off from the ends from lines V to 1, as shown by the dotted line N in Fig. 216. To make the corner block set the bevel by either line. As already explained, this operation forms the corner shown in Fig. 215.
