I made this wind driven whirligig for my father-in-law’s 70th birthday. I thought it would be a nice gift since he has been working as a logger (and still is) for at least the last 40 years of his life. He has had his own business with a harvester and a forwarder. Both machines are now sold but he still occasionally helps out driving the machines as a fill-in and also does more manual work with disforesting.
I got the idea for this whirligig when I saw the traditional “BUCK SAW WHIRLIGIG”. I thought it would be nice to make it more three-dimensional like a model and adapted towards my father-in-law’s occupation.
The figures are carved from a piece of linden tree and then painted and varnished three times to withstand harsh outdoor conditions. The short tube (that the whole arrangement pivots around) which is inserted from the bottom has a ball from a ball bearing inserted at the top. Likewise the shaft going into the tube is prepared with a roller from a roller bearing on its top so that there will be a long lasting low friction suspension of the whirligig.
Since the complete chain saw man is a bit heavy on the nose it would not start moving that easy when the weight of the figurine had to be initially overcome by the winds force on the propeller. This was solved by compensating the weight by glueing a washer on the back of the propeller. The whirligig has been tested outdoors and works great! The cat wagging its tail is the icing on the cake, an idea that came to me late in the project.
Here is a video of the whirligig in action: https://youtu.be/7IM2bnq100s
