Assembling a water wheel
====Assembling a water wheel====

* Parts of the wheel were first made up in the Blair Laboratories. They were then taken to the irrigation canal at Mazowe and assembled. The wheel was made up mostly of plywood and pine beams. The axle was made from 75mm steel pipe, reduced through reducing sockets to 50mm pipe. The axle was mounted through two sealed ball bearings mounted on the two brick built supports at the side of the canal.
* A drum was mounted on an eight metre platform high above the canal. Water and air coming from the coils was led from the axle, through a simple water seal to the vertical pipe which led to the drum. This photo shows the modified water entry point into the axle, to one side.
