Marked 1 1/4" from the end of the threaded pitot tube and placed tape on there, then attached the pitot block (didn't see that there was a threaded portion of it but got it right anyway). Made a reference mark (which will be imposible to see), then drilled with a #37 after stacking washers, making sure the drill chuck was tight against the washers, and removing a washer. Brought the screw home to make a 118 degree point... not 110. Not 120. 118. Right. Like that's going to happen. I made a point. It's going to have to do.
Also bolted on the block to the propellor hub and safety wired them in place.
