Wind turbine hub from a chopping board

White polyethylene is really expensive when purchased as an 'engeering plastic'. But it's great when you get it from cheap import shops or from Kmart.

It's resistant to heat and chemicals, soft to work with, and it absorbs vibrations.So I had a go at making a wind turbine hub from it. It is the ideal material for the job - and cheap. I'd better replace ours before my wife notices...
