Still drilling holes in the panel. First the center stack with the Garmin 496 support anf the EIS 4000.



Same picture with instruments installed.



I then dril the holes for the support rib and draw the ouline of the hole for the left side EFIS. But before drilling that I decide to drill the round holes for the instruments going beow the EFIS. I first drill 3/4" holes with the step drill bit.



I the use a punch to make perfect holes in less time that it takes to describe the process.



And here the result swith the standby airspeed indicator. The hole to the right od the center hole is normally the one for the left support rib. I will fill it before final paint.



And then I drill the EFIS hole. I'm not done yet as I still have to drill for the trim indicators, the compass, the intercomm, the park brake and various lights and switches.
