Ok show me where wooden machine out performs metal machine?

A well built wooden machine will outperform a poorly built metal one. We see it all the time over here in the DIY section. The material does not make the machine. And I said "rivals" not outperforms.

We see machines made from aluminum extrusion that are not very rigid sometimes. Most DIY'ers are not engineers so many are lacking in their design, whereas if someone with a strong engineering background builds a wood machine, it can easily rival the extrusion based one.
