Handy man's workshop and laboratory . With the aid of theworking drawings and the hints here given, the amateur mayeasily construct for himself an experimental static motor whoseaction will be highly gratifying and instructive. A horizontally oscillating lever, a, of round vulcanite rod,carrying at its extremities two hollow balls, b and b, of soft pine,communicates its motion through a slender vulcanite connecting 234 HANDY MAN S WORKSHOP AND LABORATORY rod, c, to a light flywheel, d, of thin wood. The lever, a, passestightly through a turned wooden hub, e, into whose lower end isinserted a pivot rod, /, of steel wire, slightly under y% inch insize. The lower portion of f, whose end terminates in a sharppoint, turns freely in a vertical socket, g, rising from the woodenbase of the instrument. The flywheel is supported in a similarmanner by pivot socket g\ These sockets, which are of 5/16-inchround brass rod, soldered into turned brass foot pieces, h, aredrilled longitudinally in the lathe with a ^-inch twist drill to a. Fig. 198—Plan view of the motor depth of 2}i, inches. To reduce friction as much as possible, theparts of the pivot rods within the sockets are filed down slightlyin their middle so that they may bear against the sides of thesockets for short distances only, near the tops and bottoms of theholes. A circular polished plate, i, of sheet brass, centrally locatedon the upper face of the wheel serves to give the latter a finish,and to assist in binding it with small screws upon the turnedwooden hub, k. Into the ball, b, is inserted vertically a shortpiece, /, of j£-inch round wooden rod having a rounded top to HANDY MAN S WORKSHOP AND LABORATORY 235 reduce the friction between itself and the connecting rod whoseend it supports. A round-topped conical wooden crank pin, m,rising from the wheel, supports the other end of c. The lowerend of m is turned down slightly and glued into a ^-inch holebored through one of the arms of d near the hub. The connect-i
