The photographer who does his own developing and printing has frequent use for a pair of scales. Following is the description of how a very serviceable pair can easily be made at slight expense.

For the stand is required a piece of hard wood 10" long, 7" wide, and $7/8" thick. In the center of one side cut a socket 2" long and 1" deep, to which fit an upright piece 12" long, 2" wide and 1" thick. One inch from the top of the upright drive a stout wire nail, leaving about 1/2" protruding, upon which to hang the arms of the scales. With a file, sharpen the upper side of the nail to a knife-edge, to prevent friction and secure a finer adjustment.

About 36" of galvanized iron telegraph wire or steel wire will be needed for the arms. In the center make a 1/2" loop by bending around a bolt or large nail. Then bend the wire downward on each end at points 6" each side of the center of the loop. Again bend each end outward 9" from the first bends. On these projections, which will be a little over 2" long, solder the tops of tin spice boxes. These should be of the same size and weight. If soldering is not convenient, the wire may be a little longer, and two circles made at the ends, upon which the spice-box tops or porcelain plates can rest.

When the bending is completed, file a nick in loop where it rests on the nail, to keep the arms in the same relative position. Then place the arms on the nail and bend them until they hang evenly. It may be necessary to add a little solder on the under side of one of the pans to get a correct balance. For weights, cut a piece of solder or lead into different sized pieces, and with a file and the assistance of a set of correct weights adjust until they are correct. For the smallest weights pieces of tin will be handier to handle.
