Awning whirley-gig thingy.
So, after going through two genuine store-bought Girard anemometer propellers in two weeks, I decided to try a cheaper route to the next replacement. I ordered a “Davis Wind Cup” from Amazon for $18. I drilled a small hole for the tiny drive shaft and tightened the set screw…reassembled the whole thing.
Problem was….it was made to revolve the opposite direction than the original Girard…After looking at the device, it looked like it might work spinning either direction. Eureka, it did….I’ve got the fix, now! Course it’d be cheaper if I’d stay away from the trees…
