I'm not sure of the actual material thickness there.
I'd move on to the next section while you wait to hear from the mothership.
Thanks you your input... it is greatly appreciated.
There is no next section for me to go on with... I've completed the empennage kit, I even have the fiberglass work on the rudder and Vertical stabilizer done.
I was just rechecking my work after seeing some of the notices about cracks in the stabilator hinge brackets when I noticed some of the pictures in the RV-12 Builders Blog showed a picture of the section in question and I noticed my rivets were different. I have no idea how I missed something so obvious. Brain fade is my only excuse.
I'm hoping the fact that the counter balance tube goes thru both WD-1222 counter balance brackets and then the tube gets secured to the brackets with two 3/16ths AN bolts and nuts. In other words, the brackets that hold the counter balance tube can't go anyplace once the counter balance tube is inserted without first shearing off 24 blind rivets (12 on each bracket). I would think that's near impossible but I won't let it go unless the mother ship says it's OK or gives me a workaround. I'd really hate to have to drill out about 1000 rivets.
