cutter block as described in 1 above and an appropriate
reinforcement of the same type material as that used in

the original fastener location. Secure the reinforcement

(b) After repair of the fabric in the
original snap fastener area has been completed, further
preparation of the repaired area may be required
according to the following criteria.
1. When the replacement action
involves a socket and clinch plate of a lift-the-dot snap
fastener assembly, cut an appropriate sized hole in the
repaired material to accommodate the size of the
replacement fastener clinch plate and socket. Cutting of
the material will be accomplished using a rawhide mallet
or other non-steel impact device, a lead cutter block,
and a lift-the-dot fastener cutter (fig. 3-36).

(a) General.
Installation of a snap
fastener may be performed by three different methods.
The most common method is the hand-held method that
requires the use of a leather mallet (fig. 3-37) or other
non-steel impact device, a holder to hold the appropriate
sized chuck (A, fig. 3-38), and an anvil which is used to
contain a compatible sized die. A second method of
installing a snap fastener assembly is by use of the
hand-operated press (B). The hand-operated press is a
lever-type device that can accommodate an appropriate
sized chuck and die. When installed in the hand-
operated press, the chuck and die are individually
secured in position by a threaded screw that is tightened
using a suitable sized key (Allen-type hexagon wrench )
or a flat-tip (common-head) screwdriver, as applicable.
The third method of snap fastener installation is by use
of the foot-operated press which, except for the means
of operation, functions similar to the hand-
