** A Carpenter's Gauge [19]

The home workshop can be supplied with a carpenter's gauge without any expense by the use of a large spool and

[Ill.u.s.tration: Round Stick In a Spool]

a round stick of wood. The stick should be dressed to fit the hole in the spool snugly and a small brad driven through one end so that the point will protrude about 1/16 in.

The adjustment of the gauge is secured by driving the stick in the hole in the direction desired. A better way and one that will make the adjusting easy is to file the point end of a screw eye flat and use it as a set screw through a hole in the side of the spool.

** A Flatiron Rest [19]

The iron rest and wall hanger shown in the sketch is made of sheet iron. The upturned edges of the metal are

bent to fit the sloping sides of the iron. The holder and iron can be moved at the same time.

** Use for Paper Bags [19]

When groceries are delivered, save the paper bags and use them for staring bread and cakes. Tie the neck of the bag with a string and it will keep the contents fresh and clean.

** Use Chalk on Files [19]

If a little chalk is rubbed on a file before filing steel, it will keep the chips from sticking in the cuts on the file and scratching the work.

** A Homemade Steam Turbine [20]

By WILLIAM H. WARNECKE

Procure some bra.s.s, about 3/16 in. thick and 4 in. square; 53 steel pens, not over 1/4 in. in width at the shank; two enameled, or tin, saucers or pans, having a diameter on the inside part of about 4-1/2 in.; two stopc.o.c.ks with 1/8 in. holes; one shaft; some pieces of

[Ill.u.s.tration: Details of Turbine]

bra.s.s, 1/4 in. thick, and several 1/8-in. machine screws.

Lay out two circles on the 3/16-in. bra.s.s, one having a diameter of 3-1/2 in. and the other with a diameter of 2-3/4 in. The outside circle is the size of the finished bra.s.s wheel, while the inside circle indicates the depth to which the slots are to be cut. Mark the point where a hole is to be drilled for the shaft, also locate the drill holes, as shown at A, Fig. 1. After the shaft hole and the holes A are drilled in the disk, it can be used as template for drilling the side plates C.

The rim of the disk is divided into 53 equal parts and radial lines drawn from rim to line B, indicating the depth of the slots.

Slots are cut in the disk with a hacksaw on the radial lines. A small vise is convenient for holding the disk while cutting the slots.

When cutting the disk out of the rough bra.s.s, sufficient margin should be left for filing to the true line. The slots should be left in their rough state as they have a better hold on the pens which are used for the blades. The pens are inserted in the slots and made quite secure by forcing ordinary pins on the inside of the pens and breaking them off at the rim, as shown in Fig. 4.

When the pens are all fastened two pieces of metal are provided, each about 1 in. in diameter and 1/32 in. thick, with a 3/8-in.

hole in the center, for filling pieces which are first placed around the shaft hole between the disk and side plates C, Fig. 1.
