The kind of wood finish for the stand will depend upon the finish on the wooden shade, if shade is purchased.  Brown Flemish is obtained by first staining the wood with Flemish water stain diluted by the addition of two parts water to one part stain.  When this is dry, sandpaper the “whiskers” which were raised by the water and fill with a medium dark filler.  Directions will be found on the filler cans.  When the filler has hardened, apply two coats of wax.

The metal shade as shown in the sketch is a “layout” for a copper or brass shade of a size suitable for this particular lamp.  Such shades are frequently made from one piece of sheet metal and designs are pierced in them as suggested in the “layout.”  This piercing is done by driving the point of a nail through the metal from the under side before the parts are soldered or riveted together.  If the parts are to be riveted, enough additional metal must be left on the last panel to allow for a lap.  No lap is needed when joints are soldered.

A better way, and one which will permit the use of heavier metal, is to cut each side of the shade separately and fasten them together by riveting a piece of metal over each joint.  The shape of this piece can be made so as to accentuate the rivet heads and thus give a pleasing effect.

For art-glass the metal panels are

cut out, the glass is inserted from the under side and held in place by small clips soldered to the frame of the shade.  Pleasing effects are obtained by using one kind of metal, as brass, and reinforcing and riveting with another metal, such as copper.

** Illuminating a Watch Dial at Night [149]

This picture shows a watch holder, with a device to receive an ordinary electric pocket lamp and battery.  The battery is set in a bracket under which a reflector extends downward to throw the light on the dial of the watch and to protect the eyes from the direct light.  The entire stand and bracket are made from sheet metal.  The base is formed to make a tray to hold pins and collar buttons.  It is not necessary to seek in the darkness for a push button or switch, as in ordinary devices, but a light pressure with the palm of the hand will make the lamp glow.

** Home-Made Photographic Copying Stand [149]

The difficulties of bad lighting on small articles can be entirely avoided by the use of a suitable support for the camera, the object and the background.
