Radii Chart.
Internal Contours
1.
To prepare for internal contour sawing:
(a)
Drill a
starting hole in the stock;
(b)
Run the saw band
through the hole;
(c)
Weld the saw band.
Insulate
the saw band from contact with the stock or the
worktable will insure a better weld.
Typical Internal Contour Sawing.
2.
The diameter of the drilled starting hole is determined
by the size of the saw band being used. A hole is
usually drilled in the stockpiece when a sharp corner
is to be cut, as shown in the illustration. However,
a corner may also be by-passed by cutting a curve,
and leaving the remainder to be notched out later.
Use the widest possible saw band for cutting the
curve.
3.
Attempting to cut too small a radius with too wide a
saw band will cause binding, saw band breakage
and/or excessive insert/roller wear.
4.
Radii chart recommendations are based on sawing
relatively thin stock. Consider these variations:
(a)
Use a heavy gage saw band for heavy stock sawing;
(b)
Use a narrower than recommended saw band
when sawing stock more than one (1) inch (25.4
mm) thick.
