This is just for the two people who ordered a cowling. {grin}
This weekend, Composite Dave and I fitted a cowling to my Tiger to verify the
scribe lines. For all practical purposes, we fitted the cowling (all but the
trim to fit on the upper cowlings) in two days; probably 10 hours total.
I wanted to fit a cowling to my plane because the 'trim-to-fit' scribe lines on
the four cowlings I installed early last year were close, but not close enough.
I probably spent WAAAAY too much time fitting the cowlings to those 4 planes
because I didn't trust the trim lines. For these next two cowlings, I wanted to
know where the trims lines were supposed to be. After installing one of the
cowlings last year, I asked the Team for dimensions and spacers particular to
different planes. I got a half-dozen responses; not really enough to make a
statistical judgement.
My concern was that if I sent out a bunch of cowlings to be installed by someone
not familiar with the installation, serious fitting mistakes might be made.
The final trimming, filing, sanding and fitting of a new Jaguar cowling to my
plane came out to be right on the original trim lines (with the exception of the
lower right hand corner). On the lower right hand corner, we had to sand/file
'into' the trim line by about .050 inches. So, if you drew a line between the
top of the right side of the lower cowling (where it fits adjacent to the
fuselage) and the bottom of the lower cowling, you'll see the new trim line
taper to make the bottom a little shorter. Less than 16th of an inch. As fit,
using 7/64 inch holes for #8 screws (so, there is a little play in the screw
holes) the trim lines were very close. I was very surprised.
So, if you want to install the cowling with the cowling as fitted to my plane,
installation is very straight forward. I'd trim to the outside of the trim
lines on the sides and to the trim lines on the bottom. The biggest trial and
error step is trying to work with something too big in two planes. (Geometric
planes) Your most difficult decision will be how many shims to add/subtract
from your engine mount to make your installation fit the Jaguar cowling.
If none of this makes any sense, don't worry. You're probably not alone.
By-the-way, Composite Dave was VERY surprised how difficult it was to decide
where to file/trim and by how much. We must have spent a combined two hours
discussing how much material to remove.

is there any reason why the #10 screws can't be #10 bolts? It would sure make
tightening them a lot easier.

Three pics. I set a straight edge along the rear spar. It isn't bent. Just
looks weird.
