** Fitting the cowl has seemed pretty intimidating to me. I wanted to do the piano hinges instead of screws or quarter turn fasteners. It gives such a clean look. To get the cowl in the correct place a wooden spacer was made to represent the spinner and where the front of the cowl should be. My spinner has lots of extra material behind its bulkhead, so to get the cowl moved forward enough to clear, I'll trim it back to get the proper space. Putting the full cowl on for the first time I used self-tapping screws into the joggled flange. The tape on the fuselage is 2" wide painters' tape, which is not exactly 2 inches. It was used to measure back to the cut line on the cowl. I cut and fitted a lot and then decided I didn't like the oval shape of the air inlets. The lower cowl didn't line up with the spinner well. The pencil line in one of the pictures shows the wedge cut I made on both sides to get things moved up. More sanding and fitting to get a good straight and tight joint on both sides. It is hard to get all the front faces aligned , so I got them close and I'll fill them later. Now the inlets are round. To get the rivet holes in the hinges to line up they were folded over, drilled every 2 inches, and then taped to the outside of the mated cowl. The rivet holes were drilled, then the hinges flipped over and placed on the inside. The holes match.
** I came back the next day and riveted the hinges on the sides. The following day I located, drilled and clecoed the hinges onto the fuselage. Pretty good progress.
** I now have all the electronics for the plane. Can't get to that until I'm finished with the cowl.
