I designed the instrument panel in a graphics program in full scale, then printed it out and transferred the design to the actual panel. I then took a deep breath and started cutting. Since I couldn't get the panel onto my drill press I clamped a piece of wood behind the panel and cut the holes using a fly cutter on a hand drill. I don't recommend this method. One slip and I could have really torn up the panel. Everything turned out ok, though.
Designing the electrical system and wiring the panel took a long time. It was nice to be able to wire the panel on the workbench.
I've got a fairly full VFR panel including:
Compass
Airspeed Indicator
Vertical Speed Indicator
Altimeter
Airband VHF Radio
CB Radio (everybody at our club uses a CB, so I had no choice but to include one)
Engine Information System
Various Switches, Fuses, and Indicator Lights
The Engine Information System is a wonderful little box made by Grand Rapids Technologies. It includes readouts for:
Dual CHTs
Dual EGTs
Water Temp
Tachometer
Elapsed Time
Total Time on Engine
Fuel Level
Gauge Temperature
Outside Air Temperature
And as an option I don't have, even an Altimeter
You can set high or low limits for all of these functions which will trigger an alarm if the limit is exceeded. All in that aluminum box you see right in the middle of the panel.
