Today I finished mounting the pitot tube mount. I started by drilling and countersinking the lugs to the pitot mount mast. Then I drilled the holes in the mounting plate out to 3/16". I then dimpled them to accept a 10-32 flush screw. I then attached the lugs with flush rivets to the pitot mast. Lastly, I riveted the mounting plate to the nose ribs #8 and #9. Checking for fit came up successful!
This ends all major assembly items. The next step, when funds allow, will be to begin the skinning process.
