Wood, well most wood, is heavy. Is there any such thing as people ever hollowing out the inside of the wood to make the finished product lighter?
For example, let's say I have a 4in. x 4in. x 8' piece of timber to make 4 desk legs out of. Instead of having four square desk legs of solid wood, could I hollow out the inside of the timber leaving only about a 1/2 inch thickness on each of the four sides? This would save wood for other projects, and accomplish making the desk lighter while hopefully still providing a pretty sturdy, un-wobbly base.
What tools and method could I use to hollow out the inside of this piece of timber?
