basic band saw operation
A band saw is basically a 'curve cutting" machine. It
is also used for straight-line cutting operations such
as cross cutting, ripping mitering, beveling, com-
pound cutting, and resawing. It is not capable of
doing inside cutting,
This band saw is designed to cut wood and wood
like products only.
For general type scroll cutting, follow the pattern ines
by pusnlng and turning the workpiece at [ne same
time, Don't try to turn the workpiece while engaged in
the blade without pushing t: the workpiece could bind
or twist the blade,
A curve cut _sbest performed by keeping the oattern
line in line with the blade while turning the werkp_ece
before tne radius of zne curve is cut The blade
should cut in the middle of the pattern line _saw kerr',
since wood cutting band saw blades are tnln.
NOTE: Blade guard is raised and right hand removed

1. Use both hands while feeding the work into the
blade. Hold the workpiece firmly against the table.
Use gentle pressure. Do not force the work. but
allow the blade to cut.
2. The smallest diameter circle that can be cut out Is
determined by the width of the blade. A !14" wide
blade will cut a mm_murn diameter of approximate-
ly 1-112". A 1t8" wide blade will cut a minimum
diameter of approximately 1/2".
Relief cuts are made when an intricate curve rtoo
small a radius for the blade) is to be cut but. A relief
cut _smade oy cutting through me scrap section of
workpiece to curve _n pattern line, then carefully
backing blade out. Several relief cuts should be made
for intricate curves, then follow pattern line as sec-
tions are cut off of curve "relieving" blade pressure.
