The windshield is provided in trimmed form and should not need any
major trimming. Test fitting will confirm if trimming is required. Please
review the link below on tips for successful trimming and drilling of Acrylic.
•
Observe all Safety and Health Warnings when handling Acrylic.
•
Sandbags or similar weight will be required in part of the assembly to hold
the Windshield in place.
Below are some hints from the Acrylic Windshield Manufacturer.
What is the proper technique for cutting a windshield?
•
Before you begin trimming your windshield, trim the protective film back
away from the line. Tape the edges down with clear packing tape, also
tape any seams of the protective film. This will prevent Acrylic chips and
dust from getting under the film. An abrasive wheel powered by a drill,
Dremel tool, or a die grinder is recommended. Reciprocating saws like
jigsaws or sabre saws are not recommended and will probably break your
windshield. A tool that grinds the windshield is best. Mark your
windshield with a grease pencil or a Sharpie. Allow the windshield to
warm to room temperature. Do NOT allow the windshield to vibrate or
chatter while cutting or it may chip or crack. Support your windshield so it
will not twist or spread during trimming. Duct tape is handy to hold things
in place. Cut slowly, do not push the cutter. Let the tool do the work. Use
eye protection. Acrylic chips can be a problem in your eyes since they are
clear and difficult to see. After the windshield is trimmed, use a hand-held
belt sander (we prefer the 3"x18" 40-60 grit) to sand down to your line.
De-burr the edge with a scraper or sandpaper before trial fitting to keep
from breaking the windshield or cutting your fingers.
What is the proper technique for drilling?
•
When drilling Acrylic, best results will be obtained using commercially
available acrylic drill bits (We recommend the Diamond Dust drill bits
available from Craftics). If the desired hole is larger than 3/16", drill with a
Diamond Dust drill bit first and then enlarge with the Unibit #2 (New styles
should not be used to drill a 3/16" hole due to the aggressive nature of the
SpeedPoint). For holes larger than 3/8", different techniques can be used.
