Again progress is being made. The hinges were deburred, the holes in the fiberglass were countersunk and the hinges riveted to the cowing. The lower cowling was installed on the plane. There are two minor trouble spots needing attention: 1: the hinge pins are difficult to install and remove. I think a little polishing may allow for a better fit as well as some lubrication. 2: Of course the usual trimming continues. The fit between the upper and lower cowling pieces is excellent, but a slight paint gap is necessary. HINT: Trying to get the correct gap I'm still using a 'hotel room key card' thickness (.025") between them is a challenge. I found that taking a piece of 100 grit sandpiper and placing it on the card and going back and forth in between the cowlings halves works pretty good. A couple of minutes of doing that, then removing the sandpaper, then sliding the room key back and forth to check for the gap is a good way to get it correct. Your results may vary. Still some tweaking to do there. Of a lesser concern there is a slight excessive gap of about .050 on the right side upper cowling to forward skin. Some filler may have to be used to close that gap OR perhaps after final installation of the top cowl, that gap may sufficiently close. Either way, not a big deal.
