Bend the other three legs in the same way, as nearly like the first one as you can. Be sure to make the four legs the same height when finished. Drill three holes for 3⁄8-in. bolts, as shown in the sketch. Seven inches below the top drill one hole in each leg for a rosette or some form of decorative treatment. These four legs are held in place by means of a tapered square plug 4 ins. long. The small end should fit the smallest width on the lamp legs and the taper 4 ins. below this width. Drill a hole through the centre of this plug for a 1⁄8-in. gas pipe, if to be used for gas. The same opening can be made for electric wires, etc., and a lamp well, placed at the end for a lamp.
To put the lamp together: Place one leg on the square plug and mark through the holes on the plug. Centre-punch these holes and drill for a 3⁄8-in. top. The hole should be drilled through the plug. Tap out the holes and bolt the two legs, one on either side. While drilling these holes be sure they are at right angles to the centre axis of the plug. This means a little blocking up on the tapered end. Bolt the two legs to the plug by using any short 3⁄8-in. bolts for this purpose. If all work so far has been carefully done these two legs will stand vertically to the plane of the table. If not they can be made to do so by taking out a little of the curve in the legs, thereby lengthening the side that might be a little short. Place one leg up on the third side and with a scratch awl mark the holes through on to the plug and drill these three holes through the plug. Tap out as you did before and put the other two feet on. Square up all the work done. Bolts are used for this purpose. Take 3⁄8-in. square bolts, 1⁄2 in. long. Reduce the thickness of the head to 1⁄8 in., flattening and rounding the top slightly. Put these in place of the temporary bolts. They will hold the sides of the lamp in place.
A decorative piece can be made out of a bolt head by placing it in the heading tool and forming a pyramid shaped head. This is pushed through the hole and riveted on the other side. Cut off a piece of gas pipe short enough to extend about 1 in. above the top of the lamp and to come within 2 ins. from the base. This is now forced through the hole in the plug. If any of the bolts should have screwed into this hole, preventing this pipe from going through, they should be filed off. To fill up the interval caused by the four scrolls bending outward on the top of the lamp, forge a round ball on the end of a square bar to fit this opening. Cut off the ball and drill a hole in through the ball to slip over the pipe. The thread on the end of the pipe should fall below the top of the ball. Make a tripod as explained in the description of the preceding lamp. Screw it in the end of this pipe tight against the ball. The end of the pipe is used for the fixtures needed.

LANTERNS
The lantern shown here is of a simple design and can be made out of material without putting in any bends or twists. The material for the making of the uprights is 1⁄2 × 1⁄8 in. steel.
The top and bottom should be made of No. 16 soft steel. The design shows that all pieces are riveted together on a framework.
