Begin by cutting equal squares, spaced 4 inches (10 cm) apart. Precision enhances the aesthetic quality of the coasters.
Ensure the plastic sheet is sufficiently thick for hollowing a circle to hold the base of a glass. Use a sheet at least 0.4 inches (1 cm) thick for this purpose.
-
With your squares prepared, use a lathe to create hollow circles.
Secure the square in the clamps and drill a central hole, 0.2 inches (5 mm) deep.
-
With the center hole established, proceed with the rest of the circle. Stop when 5 mm (0.2 inches) of edge remains on each side.
-
With a polishing machine, round the four corners and smooth the surfaces as needed. Additionally, round the edge of the hollow circle.

Enjoy your drink on a splendid coaster.
To create an under-glass coaster using a 0.8-inch HDPE sheet, you'll need the following tools and materials:
Tools
- Precision cutting tool (for cutting HDPE into squares)
- Clamps (to secure the sheet during drilling)
- Drill with a 5mm bit (for creating the central hole)
- Polishing machine (to smooth edges and surfaces)
Software
- No specialized software required
Hardware
- Lathe (for hollowing the central circle)
- 0.8-inch (20mm) HDPE sheet (primary material)
- Drill (to create the initial hole)
- Polishing pads or discs (for finishing)
The process involves cutting, drilling, lathing, and polishing the HDPE sheet to achieve the final design. Ensure precise measurements for aesthetic consistency.
