Here is a shot of the instrument panel with the big holes rough cut. I've got to deburr them, and make cutouts at the corner for some instruments that have knobs coming out (altimeter, CDI, etc). That is going to be a bit finicky.

I'll wait until the get the wing nut fasteners I've ordered before I cut the big hole where the removable panel with the gyros will go.

If you look carefully you can see where the edge of the angle that attaches the right side of the avionics tray is just visible on the left side of the three left flight instruments. I intend to trim 1/4" off that angle to make clearance for those instruments.
