Fig. 11.—Appearance of screen,
but not the correct size.
Ash-box, full size.
Our screen will now appear as shown at [Fig. 11], and is ready for fixing. To enable us to do this, as its position is at the back end of the boiler, we first remove entirely No. 4 ‘raiseup’ and this must be done very carefully. A good plan is to cut out the bottom of the ‘raiseup,’ insert your finger and gently pull it, when, with a little coaxing, it will probably come out easily. The ‘raiseup’ being removed, we fix the screen firmly in its place, using plenty of gum on the inner side of the ‘over-raiseup,’ ‘side-boxes,’ and inner boiler end. To hold it in position while drying, stick two or three pins at the bottom into the ‘foundation,’ and tie a piece of cotton through the screen holes round the dome. This cotton must not be so tight as to pull off the dome or bend the screen. Let it dry.
Fig. 12.—Tender-side.—Exact size.
The next process is to provide ‘tender-sides.’ The name indicates what they are, viz. sides to the tender. They are made of wood; two pieces, each four and a half inches long, one inch and a quarter wide, and one-eighth of an inch thick, are required. The upper corner at the front end should be cut out to correspond with the projection from side-boxes (see [Fig. 5], a). Paint chrome-green, edged with black, then divide into panels with black lines, as at [Fig. 12], which is full size, and gives the exact appearance. If found too difficult, omit all the inner lines. It is advisable to practise making these fine lines on a piece of paper before making them on your ‘sides.’
Fig. 13.—Half-size.
When they are quite ready they are placed in position (one on each side) at the rear of the ‘foundation,’ and firmly gummed. They must be in an exact line with the ‘side-boxes,’ and reach a little each way beyond the pair of tender-wheels (as shown in [Fig. 1], P to R). To connect these, take a piece of ‘thick’ card of the shape shown ([Fig. 13], a). The diagram is half size. At M O and N P, cut, as before explained, V-shaped grooves, and gum up the shape as at [Fig. 13], b.
