Empennage, Elevator (Part 25)

As I mentioned in yesterday's post, I attached the Front Spar to Ribs.  Today, the Top and Bottom Skins were riveted to the Front Spar with AN426AD3-3.5 flush rivets.  You can see the shop head side of the rivets on the Front Spar flanges circled below. 
 
Here you can see the 3M Adhesive Tape on the Trailing Edge Wedge.  It will be set in place after the Foam Ribs are installed.
 
I mixed up some Proseal Tank Sealant to install the Foam Ribs.  Here you can see one of the Foam Ribs installed between the Skins.  There is a 1/32 inch (approximately) layer of Proseal on the inside of the Top and Bottom Skins and Rear Spar. 
 
After all six of the Foam Ribs were installed, a weighted board was placed on top to hold everything tight to allow the Proseal to cure.  Now, I'll let the Proseal cure for a few days before I continue working.  As mentioned earlier, the Trailing Edge Wedge was also installed between the Skins and is being held in place with clecos.  The only two things left to do is roll the leading edges and attached the counterweights.
