HOME HANDICRAFT

steam escaping from the two small holes in the small tubes re­volves the boiler at quite a rapid rate of speed. A small pulley can be attached to the top for transmitting power.
Tin-Can Turbine
In Figure 33 we have a drawing of a turbine type of steam-engine. This is also made from tin cans without the use of wood in its construction. If you obtain a good sized syrup can, all the movable parts can be soldered to the lid and it will not then be necessary to punch a hole to put in water— everything being fastened on the cover the whole top can be removed. This model requires a cover from a baking-powder can and this cover is cut similar to markings at A and bent like those in the drawing at C. These can best be bent with a round-nose pliers after they are cut. Next, punch a small hole in the center; insert a hatpin, slip a burr on opposite sides and solder fast, being careful to get the hatpin centered correctly. Experience will be the best teacher in this. Out of some old piece of sheet brass or sheet iron, cut two pieces about 1/2 inch wide and 3 inches long; bore a small hole near the ends and in the center of both pieces, large enough to allow the hat­pin to turn freely. Bend at the bottom, as in drawing at D. Now slip them over your hatpin shaft on opposite sides and solder the bottoms to the top of your can so that they will set about like the ones in the drawing at F.
Make a little tube or use a little piece of brass tubing, partly fill with hot lead, then make a little hole lengthwise in the tube about 1/16 inch in diameter. Punch hole in top of can large enough to receive the tube, then solder in position as shown at G. Cut off your hatpin just outside of braces and solder small burrs to prevent lateral play. Fill your can about three-quarters full of water; put lid down tight, set over gas or oil stove and when you get up steam and it begins to escape you will be surprised at the speed your engine will turn up if you have made a careful job in the making of it. This one model sets forth the idea. A wideawake boy will be able to adapt this in a number of different ways.
