Riveting the F-00026-L instrument stack angle onto the F-1202B instrument panel base with the hand rivet puller. The F-00027-L&R com support brackets in front of the instrument stack angles have already been riveted in place.
Work continued by way of riveting the F-1202B instrument panel base to the upper firewall and longerons. Care must be taken when riveting the F-1201A upper firewall onto the F-1202B panel base in that the rivet’s factory heads should to be placed on the forward side of the firewall. Also, there are 8 rivet holes which are to remain un-riveted at this point in time as shown in one of the photos below.

On the right side of the F-1201A upper firewall are eight rivet holes that are not riveted at this time designated with blue tape on the Clecos … starting with the third rivet hole in from the right side of the aircraft.
After the forward flange of the F-1202B instrument base and upper motor mounts were riveted onto the F-1201A upper firewall, the panel base was riveted onto the F-1255-L&R longerons. This was done without the F-1202H-L&R canopy ribs in position … however, care must be taken not to rivet the two rivet holes for the F-1202Y strut attach angles yet.

After both sides of the instrument panel base were riveted onto the F-1255 longerons, the F-1202H-L&R canopy ribs were secured onto the panel base with Clecos. Of note, builders need to pay attention when riveting the F-1202Y strut attach angles because the rivets used here need to be much longer … they are LP4-5 pop rivets because of the combined thicknesses of the strut angle and the longeron.
Using the pneumatic rivet puller to rivet the F-1202H-L canopy rib onto the F-1202B instrument panel base. The two rivet holes in the F-1202Y strut angle with Clecos in them will require a much longer LP4-5 pop rivet.
