Soil pipe propeller

          

 

Using a piece of readily available 6" diameter PVC soil pipe, this aerodynamically 2 bladed propeller was produced.

30" in length, the pattern was printed off and glued to the inside of half of the pipe.

A hacksaw and file were used to create the propellers profile.

Because the soil pipe is made of P.V.C it will fade in U.V light - a good coat of paint should be applied.

 

New: I have read that over time, maybe 2 years with exposure to light PVC can become brittle, not ideal

when a prop is running at 200rpm - a safer alternative is to use A.B.S pipe.

Bicycle wheel hubs make good strong reliable mounts, for both the vertical and horizontal bearings. One of the flanges can be

either hack sawed off or removed on a lathe.

 

The blade profile can be downloaded as a PDF file or JPG image and printed off -  it will require 3 sheets of A4 paper .

The vertical lines are position markers. Please print in landscape at 100%
