Fig. 1 shows the table lamp complete. For it, cut two circles of sheet brass (No. 22 gauge), each 7 1/2in. in diameter. Hollow both together on a block until quite smooth, so that each resembles a bowl. Turn up a small edge on each with a jenny or bottom stake, so that one will fit inside the other. Procure a No. 2 Hinks's Duplex burner, or, better still, a complete central draught burner. Measure the bed, and cut a hole 1/4in. less in diameter in the centre of the larger bowl; turn up the edges for 1/8in. so that the bed will fit tightly over, and solder this on from the inside. Then fix the hollows together, the edge of one inside the other, and solder well round. This constitutes the oil vessel. To make the stand, cut a circle of sheet brass 7 in. diameter and hollow it not quite so deeply as the other vessel. Swage it round, leaving it plain for 1/2in. from the edge to produce a mould-like appearance and to increase the strength. Cut another circle 4 1/4in. diameter, hollow it deeply, and file it perfectly plane at the edges. Cut a hole 3./8in. less in diameter in the swaged circle, which, when edged 3/16 ia. all round, will allow the smaller circle to fit tightly over it. Solder this well from the inside.

Now make a taper tube 4in. long, 2 1/8 in. diameter at one end, and 13/8 in. diameter at the other. This must be cut according to the pattern, P'ig. 2. Bend it round over a mandrel, and braze the joint with soft brass spelter, using borax as a flux. File the joint smooth, and raise three small rings with a hand swage, starting 1/8in. from the widest end; see A (Fig. 1). Cat a hole, in diameter equal to the tube at its larger end, out of the small hollow, which is now fixed to the swaged hollow. Drop the tube in, beat over the protruding 1/8in. to the inside of the small hollow, and solder round from the inside. Then make a brass socket B (Fig. 1) and solder it to the bottom of the oil vessel. Now fix the stand on a flat surface, drop the oil vessel over it so that its socket fits tightly over the tube of the stand, square it, and then solder them together. Turn the lamp upside down and solder a disc over the larger end of the taper tube. Fill the bottom with sand, and then solder a disc on to prevent it escaping. The lamp will then not readily be overturned. .Remove solder from outside the joints with a smooth file, scrape with a steel scraper or sharp pocket-knife, and polish with emery and oil, finishing with bath brick and turps.
