sander is extremely useful for doing many different sanding
jobs. It will produce a smooth surface on a board in less
time and with less work than hand sanding.
sander also offers an important advantage over disc sanders:
The abrasive belt travels in one direction only, leaving no
swirl marks. With a belt sander, you can sand parallel to
the grain of the wood. This will produce a smooth finish free
of scratches and tiny blemishes.
the belt sander has capabilities which permit you to sand
end, miter, and bevel cuts quickly and accurately, sand convex
and concave shapes, round over the edges and the
ends of workpieces, and create compound curves in wood. You
can also use the belt sander to sharpen tools.
sander works by driving a continuous abrasive belt over two
drums: a drive drum and an idler drum. The drive drum is covered
by a nonslip rubber sleeve and drives the belt continuously
in one direction. The idler drum is spring loaded to automatically
tension the belt. The tension knob on the left side of this
drum releases a torsion spring that presses the drum forward
to tension the belt. The tracking knob (behind the tension
knob on the left side of the belt sander) changes the angle
of the idler drum in relation to the drive drum. This, in
turn, centers the abrasive belt on the backup plate. Since
the abrasive belt moves in a straight line, the machine is
particularly suitable for sanding parallel to the wood grain.
In some particular instances, especially when a lot of material
must be removed, crossgrain or diagonal sanding techniques
may be used.
width doesn't limit how wide stock must be in order to be
sanded. Repeat passes and special procedures permit smoothing
materials that are wider than the belt itself..
