In plugging screw holes glue the edge of the plug; put no glue into the hole. By this means the surplus glue is left on the surface, and if the plug does not hit the screw it will seldom show.
Where brads are used the heads should be well set in; then pass a sponge well saturated with hot water over them, filling the holes with water. This brings the wood more to its natural position, and it closes by degrees over the brad heads. The brad must have a chance to expand, when exposed to the heat of the sun, without hitting the putty stopping; if it does it will force the putty out so as to show, by disturbing the surface, after the work is finished.
CHAPTER V.
PARTS COMPOSING THE UNDER-CARRIAGE.—FRAMING THEM TOGETHER.—WROUGHT-IRON PERCHES.—BRAKES.
We have now to consider the construction of the lower framework, or carriage.
The following is a list of the chief parts of a coach, as generally known:—
Wheels.
Axles.
Springs.
Beds, or cross framing timbers, which are technically termed the fore axle bed, the hind axle bed, fore spring bed or transom, hind spring bed, and horn bar.
Perch, or central longitudinal timber connecting the axletrees.
