I also made the fully functional control stick
I have also made the a dummy engine for my 1/3 scale Sopwith pup.
I made the cylinders separately and the engine is nearly finished.
I still have to fit the induction tubes
The instruments are made by:
1) Drawing the bezel and printing it on a 3D printer.
2) Printing on paper using a laser printer the dial which is drawn in coredraw.
3) The needle is made from white plastic and is connected to a piece of wire that goes through a hole in the dial face.
This hole in the dial face has a small eyelet glued to it , the wire goes through this eyelet and is bent down on the other side to form a pendulum, this can have a blob of solder added to it to increase the weight.
4) The face of the gauge is made from perspex.
The needle can have their pendulums at different angles so the gauges all read correctly and move when the instrument panel moves.
