Homemade Ultra-Violet Lamp PRODUCES MAGIC “BLACK LIGHT”
With it you can perform unusual tests, do scientific sleuthing, and detect invisible erasures, stains, and sometimes forgeries
[no value]
[no value]
DOUGLAS LEECHMAN
"BLACK light," most amazing of many recent additions to the equipment of the scientific detective, is easily produced in your own home with an expenditure of but little time and very few dollars. These rays, the vibrations of which are shorter than are those of ordinary light, are called “black light” because they are quite invisible; but if an object is placed in their path, fluorescent light, similar to the light of luminous watch dials, is produced.

MOUNTED on the upper hinge of the right-hand front door of your car, a rear vision mirror can be so adjusted that it will show you the clearance between the running board and the curb when you are parking. Although an ordinary door-hinge mirror of the plate glass type is shown in the photograph at the right, a much wider view can be obtained if a curved, broad-vision mirror is used.

EASY WAY TO INSTALL FLOOR PUSH BUTTON

E. W. HUTCHINSON
A SERVICEABLE floor push button for an electric bell or buzzer may be made from an ordinary spring clothespin, a block of wood, a nail, a washer, and a few wood and machine screws. The accompanying sketch is self-explanatory. This style of switch has the advantage that no worn spots will appear on the carpet or linoleum because of wires running underneath, and the nail may be pushed through the carpet without materially damaging it.

MAX CHARLES PRICE
IN ASSEMBLING woodwork with screws, especially when the screw heads are to be set into holes and covered with wood plugs, it is a distinct advantage to modify the heads of the screws by using a tool like that shown. A few blows with a hammer on the tool will convert an ordinary flathead screw into a semi-roundhead screw that is more suitable for work of this kind.

ON ELABORATE model railway layouts, planned for the running of several locomotives at the same time, trouble is usually encountered with the rheostat control. The cure for this is to assemble a multiple rheostat such as that illustrated, and divide your layout into sections, each section being controlled by a separate one of the grouped rheostats.

STRONG and useful workshop clamps can be made as shown from a length of angle iron taken from an old bed frame. Cut this into four equal lengths to make two pairs. Also prepare two long threaded rods, each with an eye bent at one end. To assemble the clamps, drill a hole near one end of each of the pieces of angle iron, place the eye of one of the threaded rods between two of the angles, and fasten loosely with a bolt or rivet.

How to produce an accurate straightedge is well understood by machinists and tool-makers, but there are several points about the final lapping operation that are worth noting.
