Small Table Mirror
From DT Online
Design and make a small table mirror based around a 150mm x 150mm square mirror.
- Either a 150mm x 150mm square mirror tile or one cut from 3mm thick Acrylic mirror sheet.
- 3mm and 4mm Acrylic sheet on which the mirror is mounted.
- 5mm dia Pop Rivets and backing washers.
- 15mm - 20mm thick timber or 2mm Aluminium sheet for underframes if required as alternatives to Acrylic.
- How can an appropriate viewing angle be assessed?
- Will the mirror need to be adjustable?
- How will stability be ensured?
- Will the mirror need to match a particular room décor?
The mirror itself can be enhanced by Sandblasting or Engraving if suitable equipment is available, but a more accessible alternative may be to mask off a design with tape or self-adhesive film and use a low voltage mini-engraver or similar, to create a ‘frosted’ surface where exposed.
Design Development and Construction
If Blow Moulding is used, start with this process first, choose a larger Acrylic sheet and shape to size after.
Note: When using Pop Rivets in Brittle materials such as Acrylic, drill over-sized holes and fit backing washers either side to ensure the material is subjected only to Compression and the rivet is prevented from creating Tension as it swells inside the hole.
Testing and Evaluation
- Estimate the materials and production costs of your completed mirror (estimate a cost for your time and add a percentage to allow for equipment and energy use).
- How does the cost of your product compare with similar commercial examples?
- If commercial products are less costly why might this be so?
- Can you think how your design could be made more economically?
- Are there particular features or characteristics of your design which would justify a higher retail price?
