Cowl Fitting 4

3 hours.

The fitting of the bottom cowl continues. There are lots of ways to fit this thing, apparently. Trim the bottom to the top, trim the top to the bottom, and the science-y way, which is to draw a line bisecting a 13 1/4″ circle, then extend that line all the way out and down the cowl. Well, that ain’t gonna work. For one thing, I don’t have the kind of equipment necessary to make a perfect 13 1/4″ disc to use for reference, so that’s out. The flange up front fits OK on the left side, but it’s total crap on the right. It’s not even the same shape, really. I tried hacking off the flange at the corner where the fit sucks the most, but I need to cut it down some more.

However, I was able to get the areas on the inlet marked for trimming, which will enable a better fit along the side. When I cut the top cowl, I may have goofed. The right side wraps around so it extends 4 1/8″ down past the line of the top skin. On the left side, it extends down 4 3/4″ which is a considerable difference. However, I don’t think it’s going to cause too many problems.

Everybody says you can’t really trust the edges of the fiberglass cowl pieces, and I don’t. But hopefully I can get a decent fit on the bottom cowl this week.
