Trim the edges, and black and polish them, paying particular attention to the part about the buckle.
There is an opening from the metal loop to the buckle remaining unstitched; this, with a groove cut underneath on the lower side, is for the loop, which must be about 2 in. wide. Having inserted one side for about half the width of the tug, stitch it with six-cord double waxed thread from the buckle to the metal loop, being careful to bring the awl out with each stitch in the centre of the groove. Stitch the other side as far as the buckle and make two or three cross stitches on each side of the buckle.
If there is much unevenness on the part from the end of the loop to the buckle, a little filling may be put in the space. The loop must be longer than usual because the back-band is extra thick. Shape the loop with a thick bent loop-stick big enough to make plenty of room for a back-band. Black and finish the loop, make a pattern or check it if necessary, and then remove all unevenness, close the grooves, and trim neatly about the loop and buckle. Repeat the operation with the second tug, and then all will be ready.
The big loops for a shaft and the hame tugs, etc., must always be made of firm loop leather, which will grow hard in finishing and retain its firmness and shape in spite of rain and weather.

For the traces, trace end chains will be needed; van and cab traces are stitched to the hames, being shortened by having ten or twelve links of a chain at the other end. The traces may be 4 ft. 9 in. long by 1¾ in., being 1 ft. 1 in. longer with a chain. They must be in three thicknesses, but with two thicknesses to go through the chain dee and hame ring (Fig. 171, p. [123]).
In putting the upper and lower part together, place the light end of one against the heavy end of the other, thus levelling the trace and making it of equal strength. Shave the points well where one ends and another begins—for example, the lining in the hame ring and chain dee. Having turned the leathers down to the right length, crease and prick them, seven or eight per inch. Tack down with only the chain on and stitch the four rows, but not so far in the hame end as to prevent the hame ring being placed in position when they are finished. When both are stitched, trim, black, and polish them; then rub down the stitches underneath, and having fixed them to the hame ring, stitch them to it, and finish that end like the other parts.
