5 Best Lightweight Plywood Substitutes - 3D Insider
2. Cheaper than solid wood. The fact that plywood is made of different types of wood means that it’s possible for it to be made of both high-grade and inexpensive types of wood. Compared to a similarly sized slab of solid wood, plywood will almost certainly be much cheaper.

Far better than 50% odds on that, which is pretty good. I'd have to do the experiment and I've got too much on my plate, besides the idea of a new design in telescopes. Edited by KBK, 12 November 2014 - 10:53 PM.
In general, hardwoods such as maple wood, walnut wood, and oakwood all have dark brown color and softwoods have lighter colors. Natural wood colors can also be based on the degree of saturation (meaning how dark a color is – high color or light pale) as well as transparency (meaning matte and glossy), divided into other groups.
As the most common wood used for structural lumber, as when framing a house with studs, Douglas fir, technically a softwood, is light, straight and strong. You can rip two-by-fours in half lengthwise to build the framework for a crate, or anything else. Douglas fir can also be used to build lightweight bed frames, struts for shelving or anything that requires a sound structural framework.
Wood is classified as hard or soft. Generally, the harder the wood -- like oak and maple -- the denser and heavier it will be. Softwoods are usually less costly than hardwoods, but despite being light, they can be very strong and durable. For this reason, woodworkers use many light softwoods to make houses, furniture, cabinets and packing crates.
Now, let’s talk about wood. Wood is lighter than metal and glass. It is not as strong as metal. But it is much stronger than glass. We use wood to make lots of things. Things made from wood are usually light and hard and strong. Chairs and tables are made from wood. Pencils are made from wood. Now let’s talk about cloth. Cloth is very light.
