If this accident occurs the piece is useless.
Place the wheel in position, the longer part of the spindle upwards, and
move the standard about until the spindle is vertical in all directions.
Scratch round the feet of the standard to mark their exact position, and
solder the standard to the boiler. The top of the standard must now be bent
slightly upwards or downwards until the spindle is held securely without
being pinched.
A 3/16-inch brass nut and screw, the first soldered to the boiler round a
hole of the same size as its internal diameter, make a convenient "filler;"
but a plain hole plugged with a tapered piece of wood, such as the end of a
penholder, will serve.
Half fill the boiler by immersion in hot water, the large hole being kept
lowermost, and one of the steam vents above water to allow the air to
escape.
A spirit lamp supplies the necessary heat. Or the boiler may be held in a
wire cradle over the fire, near enough to make the wheel hum. Be careful
not to over-drive the boiler. As a wooden plug will probably be driven out
before the pressure can become dangerous, this is a point in favour of
using one.
