Acrylic Windshields are tough - BUT
THEY ARE NOT UNBREAKABLE - use care in handling and working
-
A Band saw it the most common way to trim the
edges of aircraft Windshields. Use a blade with at least 24 teeth per inch
and a high speed - about the same speed as is used for wood.
DO NOT use reciprocating saws, such as
saber saws!!!
-
A high speed router may be used for trimming,
however, a fixture guide or a very steady hand is required to use this
method.
-
To remove smaller amounts from the edge, generally
1/8 inch or less, a hand held disk sander may be used. A medium grit paper,
and very light pressure on the disk sander produces good results. A belt
sander may be used.
-
Hand tools, such as files, hand saws, sandpaper
may be used. Be careful, any binding of saws or files may cause breakage.
-
Before installing the Windshield, carefully smooth
the edges to remove notches. Acrylics are notch sensitive
-
Any drilling must be done with drills that are especially
sharpened for the purpose. See drawing
