Since I’m installing the pitot tube, I also had to find a home for the regulator. I decided to mount it to the back side of the main spar, near an inspection cover.. just in case it needs to be replaced.
I designed the bracket in Fusion 360 (which has extremely useful sheet metal tools) then cut the shape out of a 0.032″ sheet of 6061-T6 that I had on hand. I used a Harbor Freight mini bending brake to turn the flanges.
I also finished riveting the ribs, using the extension nose to my rivet gun for easier access — this made it much easier to set the larger 4.8mm rivets used for the step ribs.
Next I can flip the wing back over and nail down the bottom skin… and then I guess it’s time to start the fuel tank.
