The remaining skin to spar rivets near the hinge brackets were installed using the MK-319 rivets. It was a tight fit for all the rivets along the hinge brackets and there wasn't enough room for the squeezer to be perpendicular to the skin. In the past I made some wedges out of scraps of wood as recommended in Section 5 of the plans, but they would only last for 2-3 uses before they were crushed and unusable.
It dawned on me that a scrap piece of trailing edge wedge is perfect for the job. It has just enough angle to move the squeezer head away from the bracket and the #40 hole in the TE is perfectly positioned. I used this scrap for countersink testing and on one of the rivets I unknowingly put the TE on with a countersink laying against the rivet head. It resulted in a noticably rounded head, but I decided to leave it in place.
The upper inboard and outboard end rivets were mistakenly drilled with a #33 hole because I didn't read the plans closely enough. I opened these holes with a #30 drill and installed some NAS1097 rivets.
Blind rivets installed. NAS1097 "oops" rivets used for the upper IB/OB rivets.
I used a scrap piece of wedge TE to install the rivets next to the hinge bracket
The 2nd hole from the right was squeezed with a hole on the wedge with a CS and gave a rounded head
