Wood, Plywood, and Composites

From Idea Shop Wiki
Plywood Samples


Plywood is a sheet material composed of thin layers of wood veneer glued together. These thin layers, also called plies, are glued together in alternating, perpendicular directions to create a cross-grain pattern.

The Idea Shop stocks plywood in following thicknesses

0.125" (3mm) in Baltic birch
0.25" (6mm) in Baltic birch
0.5" (12mm) in Sande plywood
0.75" (18mm) in Sande plywood

Advantages for using plywood include

  • Improved dimensional stability
  • Increased strength and structural qualities - no "weak" direction (due to cross-hatched grain)
  • Minimal warping
  • Aesthetically pleasing finish over other composite materials


Medium Density Fiberboard (MDF) is a sheet material composed of wood fibers and a binding agent pressed together under heat and pressure to form sheets.

The Idea Shop stocks plywood in following thicknesses

0.125" (3mm)
0.25" (6mm)
0.5" (12mm)
0.75" (18mm)

Advantages for using MDF include:

  • Uniform composition
  • No grain
  • Cost-effective


Wood Glue is required if you are attempting to adhere sheets of plywood. After applying the glue, use clamps to keep the pieces together and wait for the glue to solidify. Be sure to use butcher paper (available in Assembly Area), and if you are clamping for a long period of time, please do so in the Assembly Area space.

Do not use superglue for adhering plywood or MDF.
