Tonight Sam Beale came over to help me finally rivet the cooling ramp to the belly. We also riveted the aft end of the belly skin to the center section flange. Sam has started on his RV-7A project and is now working on the rudder. He brought over his rudder so that we could work on it. The new 7A rudders do not have a folded trailing edge skin like my rudder does. Instead, the rudder is composed of two skins that rivet together at the trailing edge. To get everything to fit right without a curve, you have to proseal the trailing edge together on top of an aluminum angle to hold everything straight. Tonight, I introduced Sam to the wonderful world of proseal, also known as "black death". We mixed up a batch of the noxious peanut butter and slathered it onto the inside of the trailing edge rudder skins. Then, we clecoed every hole. We will let it sit for a few days and then "double flush" rivet the trailing edge (after removing the aluminum angle used to keep it straight). The proseal experience did not turn out too awful. We were able to get things together with a minimum of mess.
