apart. Each cutting edge is curved with the cutting edge on the convex
side. This blade has the cutting edges on each side, and the teeth run in
opposite directions of each other to allow the blade to be turned over when
one side becomes dull and unusable.
(3) Maple Solder Paddle. This paddle is made from maple wood because it
does not split as easily as other woods. It is used to shape hot solder to
the desired shape. It is used with motor oil, beeswax, or tallow to prevent
the hot solder from sticking to the face of the paddle.
Metal Body Equipment
Hydraulic Body Jack (figure 9 on the following page).
(a) Direct Acting Jack. This type jack has the power unit or
hydraulic pump integral with the ram. The action may be only one direction,
or it may work in either direction, pushpull.
(b) Remote Controlled Jack. In this type jack, the hydraulic power
supply is separated from the ram unit of the jack. The two units are
connected by a reinforced rubber hose.
(2) Remote Controlled Jack Components.
(a) Pump (B) (figure 9). It is handoperated, with all controls on
the unit. The pump also serves as the reservoir for hydraulic oil. The oil
level should be periodically checked.
(b) Ram (V). Threads on the ram are for attaching other jack
attachments. If the jack is used without attachments, a thread protector
must be used on the top of the ram body.
(c) Flexible Rubber Heads (K). Two sizes of rubber heads suit most
body needs. Rubber heads are generally used on dry painted surfaces because
they will not slip or mar the surface. These heads should not be used in or
near oiled surfaces as they can slip and cause further damage. Internal
threads are provided for other jack attachments.
