Two mounting shims under each forward HS spar attach pad were also match drilled and bolted on before VS install.<\/p>\n<\/a><\/a>The empennage gap cover under the HS was clecoed into place. The rear section overlaps the inspection port cover.\u00a0 Both are match drilled together through the longeron.<\/p>\n<\/a>The plans call for only three screws per side to hold the forward section of the empennage fairing.\u00a0 Many pilots have suggested additional fasteners to prevent fiberglass bulging due to air stream pressure over the fuselage. Here intermediate points were drilled midway between the default points. Nutplates for #6 screws will later be added to the upper aft skin.<\/p>\n<\/a><\/a>Front and rear photos of the match drill screw points on the empennage fairing. The aft points require special care when trimming to not interfere with either the elevator horn or the rudder motions.<\/p>\n<\/a><\/a>With the main empennage components staged in place, the whole fuselage begins to look like an airplane.<\/p>\n<\/a><\/a>Edges were measured against a scribe line formed into the part. Enough ‘meat’ needed to remain for the attachment screws to have sufficient structure to hold properly.<\/p>\n<\/a><\/a>Because of the extra holes added, smooth curves based on circular patterns were applied.\u00a0 Since fiberglass always seems to have numerous pinholes from the manufacturing process, a coat of Smooth Prime helps with initial underlayment.<\/p>\nThe forward and aft NACA air vents were fastened with ProSeal and #4 stainless screws into position.\u00a0 Later SuperFil will be applied to smooth out the backing plate rivets.<\/p>\n","protected":false},"excerpt":{"rendered":"
