Clecoed pitot in mast in place to try and figure out placement and how to match drill the mast support. Decided to use the right angle drill through the hole in the wing to try and access the rib to drill into. Cut a small piece of scrap to simulate the thickness of the pitot tube. Match drilled the support to the wing rib with the right angle drill (barely reached the rib) and used my new cogsdil deburring bits to deburr the rib holes.
