First instructable - give me a break.
Over the years I have improved a personal model of weathervane. Today Strolling on the beach with the grandkids, I built one for the Nth time and decided tto share.
1 seagull feather and
various sized pieces of bamboo
If it splits, the hole wasn't big enough. If it wobbles, the hole is too big. Carve away a strip about 5mm wide on both sides of the propeller, one on the top-left and the other on the bottom-right.. Shave the blades in alternate inclination.
Split a piece of bamboo to make the axis. Leave it ticker on the side of the notch, to retain the propeller. Trim the other side to fit loosely in the spacer.
Insert the axis in the spacer and balance the propeller. If one side tends to swing down, it is heavier than the other. Carve away some shavings on the back, until both sides compensate each other.
For windy days, use heavier, thicker pieces of bamboo. It will outstand months in the wind and rain. Fragile bamboo and lowest tech. handicraft amaze me every time.
While combing the beach for the materials, it’s a good idea to keep the knife closed, for safety.
It’s not an excuse if there are no drift bamboo pieces on your beach, or beach in your area.. Look around… improvise. And, have fun
