** Gasoline Burner for Model Work [55]
When making a small model traction engine or a locomotive the
question arises, "What shall the fuel be?" If you have decided to
use gasoline, then a suitable burner is necessary. A piece of
brass tubing about 3 in. in diameter and 6 in. long with caps
screwed on both ends and fitted with a filling plug and a bicycle
valve makes a good gasoline supply tank, says the Model Engineer,
London. The bicycle valve is used to give the tank an air pressure
which forces the gasoline to the burner.
The burner is made from a piece of brass tube, A, as is shown in
the illustration, 1/2 in. in diameter and 2-1/2 in. long, which is
plugged up at both ends, one end being drilled and reamed out to
5/16 in. Three rows of holes 1/16 in. in diameter are drilled in
the brass tube. One row is drilled to come directly on top, and
the other two at about 45 degrees from the vertical. It is then
fitted to a sheet steel base, B, by means of the clips, C C, Fig.
1. A piece of 1/8-in. copper pipe, P, is then coiled around the
brass tube, A, which forms the vaporizing coil.
