Had my friend Jonah weld the corners of the governor RF box rather than using aluminum tape on the inside.
Drilled a 3/4" hole in some 1/16" aluminum angle for the rotor tach pickup then cut it to shape and smoothed the edges on the belt sander, some quick engine turning and it's ready to be fit into the hood bracket and aligned with the magnet ring that will be clamped onto the main shaft.
