I could not bring myself to pay for the falcon rotor sled sprinkler from BIGSPRIKLER.COM. Ball park 150 ish bucks delivered.
So I built my own and even used the stainless steel falcon rotor instead of the lesser plastic version for a total of 43 bucks.
Note: I was worried the weight of the base would not be able to handle the “torque” of the sprinkler. However it’s so solid I can probably make the support legs 1/2 as long reducing its total size.
