Directions: Make a 21⁄2-in. circle in the centre of the 8-in. square plate. Drive this centre up about 1⁄2 in. above the level, tapering on the top to about 11⁄2 in. in diameter. To do this, place the centre over a hole in the wooden block 11⁄2 in. in diameter and drive the metal into the hole to the required depth. (See [design].)
Draw a line with the dividers 1⁄2 in. all around the edge. Be sure the line is an equal distance from the centre. Bend the sides down 1⁄2 in. all along this line at almost right angles to the surface. This bending is done in the vise. Measure off 1⁄2 in. in either direction from each corner for the feet, file out a section 1⁄4 in. deep and 7 ins. long, as was done in making the feet for the square box.
Base of lamp
Base
Centre post: Take the 10 × 5-in. piece and bend it around the piece of broom handle (or any other piece of round wood the size you wish). The two edges must meet. Scrape and solder, being careful that the solder runs into the joint. File it off flush with the top of the metal and make the column perfectly round. Place the column on the raised part of the base and mark around the column on the base with a pencil. Saw out a hole along the marked line. Push the end of the column in so that it is perpendicular to the base and perfectly true all around. Tie it in place for soldering, with the binding wire, by fastening the wire on the extreme top of the column, and carrying it to the four corners of the base. This centres the column ready for soldering. Wash the joint well, place pieces of silver around the base and column, and heat. The base should be crowned from the centre to the outer edge. To do this, place the centre on any round top wood block. Strike on the outer edges with the wooden mallet until the desired crown is formed. See that it stands plumb and does not rock. If it does rock, tap the base gently on the outer edges with the mallet until it stands firm. File and polish until the surface is perfectly smooth and free from marks of all kinds. The beautiful colours that form on the surface of copper depend much upon the finish. The body of the lamp is now ready for the cap and arms that hold the shade.
Cap: Take a 21⁄4-in. disc. Draw a circle in the centre of this disc, having a diameter equal to the diameter of the top of the column. Place this disc on the edge of an anvil stake and drive the edges of the metal over, forming a cap as described in the making of the lid of the rose jar. Divide this flange equally into three parts, drilling a 1⁄8-in. hole in each one of the three divisions. Take the three pieces of 1⁄4-in. round copper. File the ends of each one, making a shoulder on the end 1⁄8 in. and 1⁄8 in. in diameter to fit the holes in the flange. Put the end of these rods into the vise with the shoulder close to the top of the vise. Put the cap on the projecting pin, and rivet. Repeat this for all three rods. Wash the rivet joints with borax, and solder. File off any projecting parts so that the inside is flush, as this cap must fit over the column. Place the cap over the column and between the projecting arms drill a small hole through both the cap and the column, and rivet as before.
