Wing Root Doublers
Posted: Tue Feb 21, 2023 11:33 am
Wonderful weather this morning ... projected into the mid-70s by this afternoon ... Much done on the wing spar root doublers.
Measured and drilled the AN5 bolt/Pin holes in the upper doublers and the 4 BSPQ-44 rivet holes in the upper and lower doublers. Once the lift and jury struts are installed and the wing is properly aligned I'll drill through the upper doubler, through the mounting lugs and the lower end of each spar then drill and cleco the upper doubler in place. Once this is done, I can drill and cleco the lower doubler in place finishing the installation by drilling through the spar and lower doubler for the AN5 bolt/pin.
Following this I can use my new Milwaukee 2" metal hole saw too complete the features needed to fold the wing. major progress ... once the lift strut inserts arrive.
