Mechanics for young America; how to build boats, water motors, wind mills, searchlight, electric burglar alarm, ice boat ..etc.; the directions are plain and completeReprinted from Popular mechanics . The following description is how a minia-ture windmill was mad, which gave con-siderate power for its size, even in a lightbreeze. Its smaller parts, such as bladesand pulleys, were constructed of 1-inchsugar pine on account of its softness. The eight blades were made from pieceslxl%xl2 inches. Two opposite edges werecut away until the blade was about Vs inchin thickness. Two inches were left uncut keying the 5-inch pulley F, to shaft (G, ) which extended to the ground. The 2%-inch pulley, I, Fig. 1, was keyed to shaftC, as shown in Fi^. 4. The wire L was putthrough the hole in the axle and the twoends curved so as to pass through the twoholes in the pulley, after which they weregiven a final bend to keep the pulley inplace. The method by which the shaft Cwas kept from working forward is shownin Fig. 5. M, the washes, intervened be-tween the bearing block and the wire N,which was passed through th£ axle and thenbent to prevent its falling out. Two wash- fSwivelJ3ejxrtmcj C5$. at the hub end. They were then nailed tothe circular face plate A, Fig. 1, which was6 inches in diameter and 1 inch thick. Thecenter of the hub was lengthened by thewooden disk B, Fig. 1, which was nailed tothe face plate. The shaft C, Fig. 1, was^-inch iron rod, 2 feet long, and turned inthe bearings detailed in Fig. 2. J was anut from a wagon bolt and was placed inthe bearing to insure easy running. Thebearing blocks were 3 inches wide, 1 inchthick and 3 inches high without the upperhalf. Both bearings were made in thismanner. Shaft C was keyed to the hub of thewheel, by the method shown in Fig. 3. K,a staple, held the shaft from revolving inthe hub. This method was also applied in ers were placed on shaft C, between theforward bearing and the hub of the wheelto lessen the friction. Th
