Brief Description: Installed, marked and drill new pitot mast
New mast arrived. Installed and re measured / checked placement. Discovered that mast plate overlap, wing spar, allowed for more than I thought. Enlarged / re shaped hole in wing to get more overlap (more of pitot plate flange) on wing spar. Carefully marked and drilled skin / holes with skin / mast on workbench. Ended up with much better alignment and overlap. Test fitted on wing and all looks good. Not riveting bottom wing skin / mast in place until I'm done with everything inside of wing (lights, pitot tube lines, etc...)
