<\/a><\/p>\nFirst measure and trim the lower cowl such that the height from center is 1\/2 the diameter, and that the inlets are equally spaced above the centerline.\u00a0 In retrospect I should have measured from the inner ring instead of the forward surface as shown.<\/p>\n

<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n This week started the fitting of cowls together.\u00a0 Supplemental elements were fabricated which will later provide rigidity when splitting the lower cowl into two sections.\u00a0 Two lower halves will greatly facilitate the cowl removal after a three bladed propeller is installed.
