bottom of the can was removed, care being 

 taken to leave a clean edge. A round 

 piece of glass was cut out and its edge 

 covered with a strip of sheet galvanized 

 metal which was cut as shown. This 

 covering was hinged to the side of the oil 

 can and a snap fastener was attached. 



The brake drums were made of hard- 

 wood, cut and turned to a diameter of 

 6 in. The centers w^ere bored out to fit 

 over the check nut on the wheel hub. 

 The drums were fastened to the sprocket 

 by drilling four holes through the latter 

 into which were inserted screws or small 

 bolts. A strip of metal was fastened to 

 the outside surface for the brake strap to 

 rub against. Measure three-quarters of 

 the distance around the disk and cut a 

 heavy clock spring to this length. Draw 

 the temper in each end and drill two small 

 holes in one end and rivet it to a piece of 

 }2-in. square bar 3 in. long. Drill a 

 single hole in the other end and fasten a 

 cable wire for operating the brake. Bend 

 the spring to the curve of the disk and 

 rivet a strip of motorcycle brake lining to 

 inside surface. If this material cannot 



be procured, a heavy piece of leather will 

 do, but it will not wear so long. Fasten 

 the free end of the bar to the under side 

 of the outside slat at a point where it will 

 just clear the disk. Fasten a piece of 

 3/16-in. cable wire to the single hole and 

 run it down and under a wood pulley 

 placed midway between the disk and 

 brake bar, as shown, thence to the end of 

 the brake bar where it is fastened in a 

 notch. 



The brake bar is made of a piece of
