TIPS FOR WORKING WITH CARDBOARD:
The corrugation must run vertically to maximize its weight bearing properties. This is ESSENTIAL. Keep this in mind when cutting the cardboard, and be sure to double check that the corrugation is running in the right direction.
b. Strengthening Large Surface Areas:
If using Tri‐Wall, two layers can be glued together for added strength. If you’re using single layer cardboard, gluing sheets together until they are 1 1⁄4” thick will achieve the same result. To do this, spread a thin layer of white glue evenly on the cardboard. We’ve found that an old credit card works best to spread the glue. Press the layers together and apply weight (any heavy item will do) for about 20 minutes. To see a “how‐to” video watch: http://www.youtube.com/watch?v=evHXoM6GUGE&feature=plcp
Cardboard Carpentry 101: Scoring and Bending
Corrugated cardboard can be bent to create angled or curved pieces. This helps make corners more durable.
- 1.) Cardboard should be bent parallel to the corrugation rather than perpendicular for ease of bending.
- 2.) Narrowpiecescanbebentbypressingthemovertheedgeofatable.
- 3.) Wide pieces need to be scored before bending. This can be done using a blunt tool or the round handle of a tablespoon.
- 4.) To note: Sometimes you have to score farther from where you actually want the bend to account for the thickness of cardboard. For instance, if your cardboard is 3⁄4” thick, you may need to score and bend your cardboard 3⁄4” farther from the actual corner measurement.
