Figure 6-86.-Driftpins (driftbolts).
Driftpins (driftbolts) (fig. 6-86) are long,
heavy, threadless bolts used to hold heavy pieces
of timber together. Corrugated fasteners (fig..
6-87) are used in a number of ways; for example,
to fasten joints (miter) and splices together and
as a substitute for nails where nails may split the
Glue, one of the oldest materials for fastening,
if applied properly, will form a joint that is
stronger than the wood itself. Probably one of
the best types of glue for joint work and furniture
construction is animal glue, made from hides.
Other types of glue are extracted from fish,
vegetables, casein, plastic resin, and blood
albumin. Glue can be obtained commercially in
a variety of formsliquid, ground, chipped,
flaked, powdered, or formed into sticks.
