Coping Saws
Coping saws are made with a taunt thin
blade, useful for cutting unusual shapes and small curves
in wood. Typically, it is used on trim work, where a cut
is made so that one contoured molding can join neatly with
another. The blade is designed to cut along a wide range
of angles. The fretsaw is closely linked to the coping saw
because they perform similar tasks.
The coping saw consists of a U-shaped metal
frame attached to a hard wood handle. Within the metal frame
contains a thin blade. The frame and the blade are connected
to the handle with a slotted pin. By turning the handle,
the tension of the blade will either tighten or loosen.
Also, holders are placed on both ends of the blade that
can be adjusted for different angles.
The blade on a coping saw is 150mm in length
and at each end there is a pin that holds the blade to the
frame. If you are fitting a new blade in, the frame will
need to be flexed. Once flexed, the blade will fit into
the slotted pins on the frame. When the pressure is released,
the frame will spring back into position and hold the blade
in place.
Not only are coping saws great for fitting
molding into corners and making small curved cuts, but it
is also great for cutting shapes in the middle of a piece
of material. In order to make such cuts, the blade must
be removed, placed through the hole, and then re-attached.
The saw can then be used in the usual way, cutting the "inner"
shape.
