It extends beyond the body towards the rear for 1.6 metres. In order to glue it, proceed as follows:
Spread the glue on 800 mm. of the lath in such a way that after a minute the face of the wood is covered uniformly without any blank spaces. One nail at each end will keep it steady, and then nail it in zigzag fashion approximately every 20 mm. (see Fig. 2). After nailing it, the glue will ooze out along the edge. You can smooth it off when it is dry.
Proceed in the same manner with the other laths, which, as you see, leave 30 mm. spare along edge No. 1. Fix the other laths in the positions shown, and then the stops. The rear lath, before it is put in place, should be pierced with two holes at a distance of 40 mm. These will receive, later on, the anchorages in the screwed rod of the harness. Take care that there is no empty space at the end of each lath.
Make the fillings (Fig. 2) with the ends of laths. With the point of a knife cut out the plywood sides opposite this empty space, where the pulley which takes the rudder cables is to be fitted. Cut out also the quadrilateral through which the axle will pass.
Cover all this assemblage with the panel (Fig. 7) in 3 mm. plywood. Prepare the other side exactly the same as the fist, but in the reverse order.
It must be understood that where wood touches wood there is gluing and, nailing.
From a piece of mild steel 1 mm. thick cut with shears two strips which, when folded, will clasp simply by gluing under the feet a skid (Fig. 12) in hard wood, such as oak, walnut or beech. The holes in these straps will he drilled beforehand on one side only. The other side will be drilled for receiving the bolts, after it is in place and solidly fixed by a binding or by a hand vice on the longeron. These bolts, in screwed rod, will fix as well the short strips which are inside the fuselage.
The skid and the straps are designed to reinforce the longeron when the axle strikes it after joits. A block in hard wood is glued and screwed on the skid at an equal distance from the straps, to prevent the elastic shook absorber of the axle from slipping.
Glue the blocks this last one made of hard wood for bolting the metalwork for the wing bracing wires. The lath which serves as the reinforcement gets progressively thinner towards its end.
