34 - Baggage Door

Image
I started on the baggage door by carefully bending the frames as outlined in the plans. I then skipped over the final drilling as the holes were already final sized, and cut the hinge to the specified length. To make the baggage door removable, I decided to do what several other builders have documented, and split the hinge pin so that the two pieces can be inserted from the center of the hinge. This also requires the hinge halves to have a portion of a few eyelets removed to allow the hinge pins to be inserted. With the hinge pin inserted from the center of the hinge, the hinge itself can be attached so that it is almost flush to the fuselage skin. Hinge pin halves will be held in place via a 3D printed clip that is screwed to the F-1058 Hinge Frame. Hinge after match drilling to the F-1058 Hinge Frame and hinge pin modification After match drilling one side of the hinge, I clecoed the hinge to the baggage door frame, and the frame to the exterior baggage door cover, and then clamped...

SDS Fuel Pump Tunnel Mount

Image
While working on the forward fuselage a while back, I gave some thought to how the SDS EFII fuel pumps will be installed in the tunnel. The fuel pumps will rest on a shelf that is attached using the same pull rivets that hold the floor panels and tunnel access panel doublers in place. Rather than installing a shelf that extends fully along the bottom of the fuel pump mount, as some others have done, I decided to create two smaller shelves at each end of the pump mount. I started by cutting 4 pieces of 3/4"x3/4"x1/16" angle to a length that would span 3 rivets (with appropriate edge distances) along the floor panel rivet line in the tunnel sides. Angle shelf supports cut to length and deburred After marking a line down each support  5/16" from the edge, I marked and drilled a #30 hole to use as the initial rivet hole Initial rivet holes drilled in all angle supports Angles were then clecoed in the appropriate locations in the tunnel ensuring that the shelves would su...
