Fig. 68.
The lantern shown in [Figure 66] consists of four sides which are fastened together with angles and rivets. The top is made from four pieces, with angles also riveted to them. The stock is cut with a pair of snip shears, No. 06½. (See [Figure 67].) The sides must be cut to the same size or there will be trouble in putting them together. After they are cut, the open work is marked with a slate pencil. Holes are drilled in the corners of each opening, and they are cut out with a sharp chisel. The edges are filed and all holes are drilled for No. 12 rivets. At [Figure 68] is a drawing, with dimensions of one of the sides as it should be in the flat. Notice the section of the sheet bent at the top for the roof and at the bottom to hold the glass. The glass is held in position at the top with a little strip of copper, with a rivet to hold it. The glass is set into the groove at the bottom, and the copper cleat is bent over the top of the glass. The copper cleat should be ⅞ by ⅜ in., made from No. 26 soft copper. The bottom of the sheet is first bent at right angles, then a flat piece ³⁄₁₆ in. thick is laid on the inside of the sheet, and the whole is placed on the anvil. The end of the sheet is now hammered over the ³⁄₁₆-in. piece with a mallet to make the pocket to hold the glass. All of the holes for rivets to fasten the angles should be countersunk a little on the inside. The angles are made from one inch wide No. 20 hoop iron. They are formed by placing them between two pieces of flat iron as shown in [Figure 69], and holding the whole in a vise while hammering with a wood mallet.

In fastening the angles to the sides, the heads of the rivets are on the outside, and the inside is smooth. In doing this, the heads of the rivets are held in a rivet set while hammering on the inside.
