Creating Laminating Base - V1 - Wood Support¶
25° wooden base with acrylic sheets for laminating carbon fin blades.
Goal¶
Create a rigid angled surface to support fin blades during lamination.
Specifications / Dimensions¶
Dimensions
- Long Side (Flat):
- Minimum width: 25cm (to accommodate 20cm blade width and additional room).
- Minimum length: 30cm (to fit a 25cm blade length and additional room).
- Angled Side (23°–25° Incline):
- Angle: 23 degrees (or 25° based on matching geometry).
- Minimum width: 25cm (to match blade width).
- Minimum length: 20cm (to fit 15cm blade length and extra space).

Instructions (step-by-step)¶
-
Base Construction
- Use 1cm thick timber to create a solid base.
- Cut wooden side supports to a 23°–25° angle to replicate blade geometry.
- Secure side supports to the flat base using metal brackets for rigidity.
-
Laminating Platform
- Tape clear Acrylic Perspex sheets (A3 and A4 sizes) onto the wooden base using thin double-sided adhesive tape.
- Ensure the surface is smooth and taut to properly press against the blade.
Data to Record / Results¶
- Notes on surface flatness after cure
- Any deformation or movement during lamination
Limitations¶
- Does not scale well: In order to create bigger fins, the wooden structure needs to be re-worked.
- Vacuum Bag Fit: Ensure the base with acrylic layers fits entirely into the vacuum bag.
- Air Trapping Issue: The gap between the angled section and wooden supports bends the acrylic during vacuum bagging
