Installed the inner cylinder baffles/ Installed the long bolts on the cylinder baffle flaps. Worked on fitting the filter airbox to the lower cowling by adjusting the forward most ribs with the fluting plyers. this required removing and reinstalling the airbox and cowling multiple times. Cut the fiberglass portion of the airbox and bent upward to fit the updraft of the top plate. Mixed up fiberglass and set rivets and glassed the lower half.
