Panel Photos

I elected to go with a two piece removable panel for easy avionics maintenance. The removable panel sections are attached to a sub frame with screws. 



First I created a detailed mockup on cardboard...



The subframe is created by removing most of the metal from the stock instrument panel, leaving a frame which will be riveted to the fuselage



Punching instrument holes in the panel section using hole punch rented from Averys ($15)



Subframe with initial wiring

Two panel sections (with instrument holes) in place on subframe

Most of the instruments in place, ops check OK!

There's a blank space under the transponder for an IFR GPS (when prices become reasonable and precision GPS approaches are routine)
