How to Make a Water Motor
By Edward Silja
After making several different styles of water motors I found the one illustrated to be the most powerful as well as the simplest and most inexpensive to make. It can be constructed in the following manner: A disk, as shown in Fig. 1, cut from sheet iron or brass, 1/16 in. thick and 9-3/4 in. in diameter, constitutes the main part of the wheel. The circumference is divided into 24 equal parts, and a depth line marked which is 8-1/4 in. in diameter. Notches are cut to the depth line, similar to the teeth of a rip saw, one edge being on a line with the center of the wheel and the other running from the top of one tooth to the base of the preceding tooth.
Metal Disk with a Saw-Tooth Circumference That Constitutes the Main Body of the Wheel (Fig. 1)
A 1/4-in. hole is drilled in the center of the disk and the metal strengthened with a flange, placed on each side of the disk and fastened with screws or rivets. A 1/4-in. steel rod is used for the shaft.
The cups, or buckets, are shaped in a die which can be cast or built up of two pieces, as desired. Both of these dies are shown in Fig. 2. The one at A is made of two pieces riveted together.
