Now obtain a piece of deal about six inches long and rather more than an inch square; the corners are to be cut away at one end, so that the end is shaped something like a glass shade; then with sand-paper (coarse first and then fine) the rounded part is smoothed; cut it off square, about one inch and a quarter from the rounded end, as [shown] at A B.
This is the ‘DOME,’ and if it be gilded with a little of Judson’s or Bessemer’s gold paint, it adds much to the appearance; when gilded and dry, stick it on the ‘dome-box;’ it should exactly reach the centre of each side of the square; looked at from above, it appears as at [a]; looked at from one side, it appears as at [b].
STEAM FUNNEL
Next take a piece of rather stout note-paper, about six inches long and half an inch wide, roll it round a piece of slate-pencil several times, gum the outer end, and when dry slip it off; cut a circular piece of medium card to fit the end, which should be about half an inch in diameter; now roll another piece of paper about a quarter of an inch wide so as to make a roll about a third of the diameter of the preceding, gum the outer end as before, and fix it in the centre of the circular card; cut a second disc of card with the centre cut out just to fit on the top of the small roll; it will then appear thus: It is called the ‘[steam-funnel]’; it is to be painted ‘chrome-green’ and edged with black; its position is the centre of the back ‘over-raise-up.’
We must now make our screen. For this we require a piece of thick card three and a half inches long and two and five-eighths inches wide. It is to be of the shape [here] given, but the width must be such that it will fit tightly in between the side-boxes (see b, [Fig. 8]) at the rear end of the boiler; the top must reach about half an inch higher than the steam-funnel and be rounded at the corners. In this two circular holes of about three-quarters of an inch in diameter must be cut; their position is half an inch below the top and a quarter of an inch from the sides; paint it chrome-green and edge with black. If pieces of circular glass, such as are used for covering objects when mounted for the microscope, were placed over the circular holes, and gilded round the edges, they would improve the appearance; they are not essential. On this screen we now provide a circular piece of thin card of the same diameter as the large end of boiler—viz., two and a quarter inches; this must be painted black, and is then gummed on the screen so as to correspond with the boiler end when the screen is in position; a hole, horizontal at the top and circular below, of this shape and dimensions must now be cut through both cards for an ash-pan, the lower edge being about one-eighth of an inch from the edge of the circle; at the back, over the hole, gum a piece of paper painted vermilion, and dotted with black to represent fallen cinders.
On this boiler end must now be made furnace and furnace-door. For this take a piece of ‘medium’ card, and on it describe a semi-circle, with diameter one and three-quarter inches. In this make a door shaped as in the [diagram], cut quite through the part marked a, b, c, d, except where the dotted line comes. Where this dotted line is shown it should be cut on the reverse side of the card, half through the card. This is the door, and it will then stand partly open. Round the circular part gum a piece of thin card, one-eighth of an inch wide. Fasten down with pins as before to dry, as annexed. When dry, paint the part which is to show outside black, and stick a piece of paper painted vermilion on the inner side of door. The vermilion should show through the partly open door, in order to give the ruddy appearance of fire. This furnace end may now be gummed on the boiler end (see [Fig. 11]). When in position the bottom will be parallel with the top of the ‘ash-pan’ opening, and about one eighth of an inch above it. It will stand out from the boiler end. Now with a large pin make holes all round the edge of the boiler end. They should be close together, like this:
. In these holes insert pins, with the heads showing outside, and this will give the effect of bright rivets.
Next take a piece of medium card, and make it of this size and shape:
