Fabricate a Lexan nose bowl disk to replace the OSB disk. It's thinner and can be clecoed to the cowl. Raise the tail with a longer upright to get the longerons level. This leveled the rear longeron but upon further consideration I probably want to level the forward longeron. Added center lines to the upper and lower cowl. Modified a rubber plug inserted into the crankshaft to block moisture. The plug was initially slightly too small for a tight fit so I expanded it using a 2" socket as a mandrel and a heat gun. Then I trimmer the outer diameter to the same size as the crank OD. Attached the David Howe Ez Cowl Jig to the crank prop flange.
