Just plugging away. Little by little. Working around the pitot mask is a bit tricky. Just more angles to work around with your hands. Progress is slow, but the rivets are nice. One thing is for certain, this installation makes for a very solid pitot mount.
Here is a look at the inside mounting of the pitot bracket to the stiffener. I used bolts so all that is need to do is drill out 5 rivets and remove two bolts that hold the mast to the stiffener, and the pitot mast slides out of the wing. Without the stiffener the pitot mast is not very solid.
