Tech details, dimentions

Sizes

When I planned my project I've looked for info about dimensions in the internet, but not found exact sizes.

I've loaded lot of photos of the Baron cockpit, then calculated all sizes in the graphic editor using all well known dimensions, such as cutouts for 3 1/8" instruments, sizes of the GPS, ADF etc.

So I got all sizes that, I believe very close to original (+/- 1cm at whole panel width, or 1%).

Knobs and buttons making


Knobs

For the smallest knobs (used as GPS, ADF, COM/NAV volume control) might be used any suitable cylindrical parts (caps from pens or casing from some electrical connectors as in my case)


Another method was used for making knobs for the transponder, altimeter and ADF Indicator. The knobs of suitable diameter from some old cassette player. They have smooth surface, so I've graved notches with simple "router", made (that took about an hour) from the monitor stand and drill.

 

And, for some knobs would perfectly fit the caps for tubes of glue, creams etc. If diameter is not fit, some of them could be cut and glued for needed size.

 


Buttons




Switches instead of encoder

Instead of encoders in some cases the couple of button swithes can be used ( or two-way switch).
For the transponder two-way springed micro switches was used:

    

These microswithches can be found in any old CDRom:



I have removed small lever and glued the knob to rotating disk.
