It's barely visible, but it is twisted. Some time ago I was messing with 3d software and first thing that came to my mind was to make wind turbine blade. I left memory stick in a workshop with file, but as far as I remember there is 5 degr angle at the tip and 10degr at the root. Blade was designed to fit 120x45mm 650mm long leftover timber from Wickes I had.
I may someday consider to make the proper ones and raise some wind turbine:whistling:,but those damn stupid permissions- can spoil whole fun of hobby engineering:sad:.
I'd like to make them fiberglass ones, but wooden ones sanded, dyed and high gloss lacquered- pure beauty- I could keep then in livingroom and enjoy their stunning look
