First RainFLOWr at northLake community garden is finally complete again. After some experimentation, modification, and repairs, i think it is finally ready to go. I modified the tarps to have a rounded petal rather than it being straight across.
I was hoping to use bamboo as support for the arch, but it turned out to not work out very well. The pieces had to be too long for the bamboo i had available to me and the it kept breaking at the joints when i tried to bend it. As such i have gone to 1/2″ pvc for the supporting structure.
I also had to upgrade the brackets that hold the arms from unistrut to 1/8″ steel angle. The unistrut just could not stand up to the stress of the uplift caused by the wind. I am pretty confident the steel L will be plenty strong and i can avoid tying the arms back to the ground which would be undesirable on several levels.
I will be working on building a page for the RainFLOWr on the website. In the meantime, pictures of the completed RainFLOWr can be seen here.
