The tube extends beyond the sides of the fuselage for about 50 mm. Two flared sleeves prevent it from sliding laterally, and, if possible, without any play. Put washers between the fuselage and the sleeves.
These sleeves carry the levers made from 10-mm. bar heated to a red heat, flattened at one end and riveted at the other so that they will not come out of the sleeve. This sleeve is fixed to the tube by a bolt of 6 mm., taking care that the lever, when looking at it from the end of the tube, is at right angles to the joystick.
This latter disposition is for the control of the wing, to which the eyes of the levers, one on each side, will be fixed by a control cable.
Fitting the Rudder and Wing Control
The control of the rudder and wheels can he placed in position. Two cables
5 metres long of 2.4-mm. section steel and extra flexible, will be passed through the 6 mm. diameter hole in the joystick, and prevented from moving at the middle point by the 5 mm. diameter bolt. Each double turn will cross with the other in the 5mm.diameter hole, in a similar manner, in the fork. Before this, the joystick will have been filled with hard wood, well greased with paraffin wax, level with the base of the stick.
The fork, partly of wood and partly of metal, should he filed round. The 4-mm.
rivet prevents the cables from escaping from the fork. It is flush with the outside of the joystick. A drop of oil win prevet wear on the cables.
Each double cable, of a longth of 2 metres 50 mm., passes over the pulley. (T
a cast pulley and has a very, wide groove: the diameter at the bottom of the groove being 40 mm. at least, which revolves on the axis of a diameter appropriate to the hole through the centre of the pulley.) A nut on the interior of the fuselage at one end, a 'bearing: at the other, and a screw 184 x 5 x 25 mm. fix this axis, which will be slightly inclined by means of a block under the bearing in order that it can be aligned with the bottom of the control stick.
Finally, the double leads join up with the turn-buckle where they are attached by the grip, adapted for cable of 4.5 rnm. Bind each free end and join the ends to the cable They will be about 50 mm. to 100 mm beyond the grip.
The little piece of strip steel of 2 mm., fixed by two screws close up to the pulley, will prevent the cables from jumping out of the groove and jammng if they become slack. This is a wise precaution, as jamming of the cable is much to be avoided.
The Wing Support
The support consists of a pylon made of tubes which sustain the tub wing and
positions it after it has been fitted with its bracing wires.
It is made of two tubes in 17 mm. x 20 mm., welded to two cheek pieces of 2 mm. separated by a block of hard wood and joined by two bolts of 6 mm. (see Fig. 18). Where welding is not possible it can be bolted together. This is the head of the pylon.
The feet of the pylon, lightly bent (at red heat), are blocked with hard wood, and are pivoted at the U-piece in 2 mm. material furnished with a 6-mm. bolt. This is joined to another piece of metalwork by two 6-mm. bolts which go right through the crosspiece, to which they give great rigidity. On the other hand, the metal piece is fixed by three 4-mm. bolts to the three laths of the landing gear.
It would be better if the feet of the cabane were finished off by a transverse tube welded on to them.
The head of the pylon is kept in position about 300 mm. long-the exact
decided at the moment when the vwing is adjusted-and which is pivoted at either end on the 30-mm. tubes made of a a 1.5mm. strip rolled.
The axis tube of the foot is fixed between two strips of metal bolted to the motor when that is in place in place.
