WingSet41Ann

This morning I finished preparing the spar support blocks. Scuff sanded the bottom of the blocks and the spar entry where the block was to be bonded. Mixed up a batch of Araldite 420 A/B and added milled glass fiber for strength and to keep the Araldite from running. Carried the Araldite/MILL and blocks out to the aircraft. Applied the Araldite/MILL to the bottom of the Port block, lifted the spar and slipped the block in place. Used the weight of the wing on the spar to hold it while the bond cures.
