I got up early today and got a lot done. I had been putting off drilling the new panel for the Garmin Stack. I woke up with a good procedure, went to the shop at 6 AM and started drilling. The process only took a few minutes and I was able to mount the Garmin Stack. Alignment is dead on.
From there, I used the left avionics support as a template to create a center and right side support. These blanks are deburred and ready to mount.
