Nieuport Build Part 2 - Cockpit Detail

The cockpit detail was made from balsa wood, bass wood, hardwood dowel, stiff card, K&S aluminium tube, aluminium sheet, cotton thread, nuts & bolts, dress making pins, veneer pins, clear plastic sheet, wire, stain and paint to finish.



These are all the items made, control column, throttle lever,
instrument panel, seat and rudder bar assembly.


Control column - complete.

cables and aluminium cross tube with aileron push-rod connections

Made from hardwood dowel (horizontal part shown unpainted) with a hand carved bass wood end attachment that was fixed to the dowel and holds the vertical joystick and the horizontal aileron tube. The joystick pivot is a section of aluminium tube with the ends flared out to retain it in the wooden housing. The elevator fixings are from aluminium tube, sheet aluminium, small brass nuts and bolts and brass veneer pins with heads filed flat to simulate fixings.


Elevator connection.


Aileron push-rod connection.

The horizontal aileron tube was made from aluminium and the ends were made from servo ball-joint fixings.The balls were filed flat on either side and the finished items were then glued into each end of the tubing. 




Joystick.

The joystick was made from hardwood dowel and the end detail was achieved by inserting the dowel into a rotating electric dill and using files to make the desired shape. The top of the joystick was then wrapped in cotton thread.




Throttle assembly - complete.

The wooden support was made from balsa wood with a plywood facing to each side to hold the 2 levers in place. The levers were from piano wire, aluminium sheet, litho plate, wood for the handle and the head from a map pin. The frame was held apart with brass wire and aluminium spacer tubes and 2 nuts and bolts hold the finished unit to the wooden support. It was painted prior to final assembly.



Instrument panel - complete


Clock detail.


Altimeter detail.

The 2 instruments were made from paper tubes glued together with super glue and sanded to shape. Details are from aluminium tube, brass watch screws and small brass BA nuts and bolts. The dials were originated on a computer then printed out.  The hands were from paper soaked in super glue to give them rigidity and painted.



Oil level indicator detail

 This was made from a miniature test tube with a section cut off. The remainder was made from various pieces of tubing, wood, wire, nuts, bolts, washers and brass strip.


 Seat - front view, showing 2 aluminium fixing straps to seat base.

Seat - rear view showing the array of lightening holes.

Seat - Underside view, showing rear mounting brace, brace made from card.

The seat was almost entirely made from paper and card. A seat base was cut from card then the seat back was cut from stiff paper. The holes were marked in position and cut out, the edges were then soaked in super glue to add strength. The brace was made from thick card and the front fixings traps made from aluminium strip and fix to the seat with small nuts and bolts. The finished set was sealed and given a coat of paint then weathered to give that 'used look'.
  


 Rudder bar assembly - front view.

Rudder bar - closeup.

The main structure consisting of foot rests and framework were made from balsa wood and plywood.  The rudder bar support was hand carved from bass wood using an electric drill with cutting burr fitted and plywood for the base. Brass veneer pins with the heads filed flat were then added to the plywood base detail to simulate fixings. The rudder bar was made from balsa wood, balsa dowel and styrene sheet. A bolt was used in the centre to allow it to rotate and the same servo ball joints as used for the aileron push-rod connections were used to allow for rudder cable fixings.


Part 3 of the Nieuport Built - I will be constructing the top wing, complete with additions...
