Designing and Preparing the Plexiglass Windshield
Choosing the Right Plexiglass Type and Thickness
When creating a plexiglass windshield, it’s essential to choose the right type and thickness of plexiglass for your specific application. There are two primary types of plexiglass: standard and impact-resistant.
- Standard plexiglass is the most common type and is suitable for most applications, including aircraft windshields.
- Impact-resistant plexiglass, also known as tempered plexiglass, is designed to withstand high-impact forces and is often used in applications where safety is a top priority, such as in heavy machinery or military vehicles.
When selecting the thickness of your plexiglass windshield, consider the following factors:
- The weight of the vehicle or aircraft.
- The speed at which the vehicle or aircraft will be traveling.
- The type of application and the forces it will be subjected to.
As a general rule of thumb, the thicker the plexiglass, the more durable it will be. However, thicker plexiglass may also be heavier and more difficult to work with.
Table: Recommended Plexiglass Thicknesses for Different Applications
| Application | Thickness (mm) |
|---|---|
| Aircraft Windshields | 3-5 mm |
| Heavy Machinery Windshields | 5-8 mm |
| Automotive Windshields | 2-4 mm |
Measuring and Cutting the Plexiglass
Once you have chosen the right type and thickness of plexiglass for your windshield, it’s time to measure and cut it to the correct size. You will need a high-quality cutting tool specifically designed for plexiglass, such as a plexiglass saw or a laser cutter.
To ensure accurate cuts, use a template or a pattern to guide your cutting tool. You can also use a measuring tape and a calculator to double-check your measurements.
When cutting the plexiglass, apply gentle pressure and maintain a steady hand to avoid applying too much pressure, which can cause the plexiglass to shatter.
Tips for Measuring and Cutting Plexiglass

Shaping and Sanding the Plexiglass
Once you have cut the plexiglass to the correct size, it’s time to shape and sand it to achieve the desired shape and finish. You will need a variety of tools, including a jigsaw, a sanding block, and a drill press.
To shape the plexiglass, use a jigsaw to cut out the desired shape, and then use a sanding block to smooth out the edges and surfaces. You can also use a drill press to create holes for screws or other fasteners.
When sanding the plexiglass, start with a coarse-grit sandpaper and progress to finer grits for a smooth finish. Be sure to wear protective gear, including safety glasses and a dust mask, to avoid injury from flying particles.
Table: Recommended Sanding Grits for Plexiglass
| Grit | Description |
|---|---|
| 80-100 | Coarse-grit sandpaper for rough shaping and sanding. |
| 120-150 | Medium-grit sandpaper for smoothing out edges and surfaces. |
| 220-240 | Fine-grit sandpaper for final smoothing and polishing. |
Assembling and Installing the Plexiglass Windshield
Once you have shaped and sanded the plexiglass, it’s time to assemble and install the windshield. You will need a variety of tools, including a drill press, a screwdriver, and a wrench.
To assemble the windshield, attach the plexiglass to a metal or plastic frame using screws or other fasteners. Be sure to align the plexiglass carefully to avoid any misalignment or distortion.
When installing the windshield, apply a sealant, such as silicone or caulk, to create a watertight seal. You can also use a weatherstrip or a gasket to create a seal.
Tips for Assembling and Installing the Plexiglass Windshield
- Align the plexiglass carefully to avoid any misalignment or distortion.
