The next operation is cutting grooves for the steps to set into the legs, and this requires considerable care.
The lower step is 5-3/4" from the lower end of the legs. This dimension is measured off on each leg, and a line is drawn parallel with the lower end of the leg. This may be done by either using a T bevel, set at the angle of the lower end of the legs, or the dimension, 5-3/4", may be measured up on both sides of the leg and a line drawn across.
Next take the lower step and mark one end A and the other end B. Place the end A, of the lower step, evenly on this line and make a mark above the first line a little less than the thickness of the step. The groove is marked a little less than the thickness of the step so that, in case the saw cut is made a little wide, the step will not be likely to fit loosely.
Square lines across both edges of the edge from the end of the lines previously drawn and measure down from the surface a distance of 1/4" on the edges. Draw a line through this point parallel to the edge of the leg.
Next saw carefully on the lines, first drawn, down as far as this last line and cut the wood out with a half-inch chisel.
If the step will not fit in the slot, plane a very slight amount from the surface of the step until it fits snugly into the groove.
End B is fitted to the opposite leg in a similar way and the second step is placed in a like manner, 6-7/8" above the lower step.
If the drawing is examined, as these directions for placing the steps are read, the explanation will be greatly simplified.
The two narrow cross braces are next made, 3/8" × 5/8" × 15-1/2". These are crossed at their middle point in a middle-lap joint, a groove being cut half through each piece wide enough to insure a tight joint. These braces are attached to the rear legs, 2-1/2" from their lower ends, with 3/4" No. 6 flat-head screws, the holes being previously bored and countersunk.
Cut the ends of the braces even with the ends of the legs.
