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)
