Brazing Torch: a Pressure-Tank Gasoline or Kerosene Torch (Shop Notes, 1909)

Cap both ends of a 2 in pipe 20 in long. Drill three holes in the top cap: one for the rubber tube from a bicycle pump, one for a steam gauge, and one with a screw plug for filling with fuel oil.

Drill the bottom cap and connect a 1/8 in pipe D, any length, with a globe valve in it to set and shut off the oil. Fill the last 10 in of the pipe with lead, coil it round a 1 in pipe F 6 in long, and turn the end out to take two elbows and a short nipple; then melt the lead out. Drill a small hole in the centre of a 1/8 in cap and fit it on the end (E) so the hole lines up with the centre of pipe F.

Hang a little cup holding three or four teaspoonfuls of oil just below the coil and light it to heat the coil; then pump up the tank and open the globe valve. For more heat connect two burners on a tee so their blasts meet.
