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. ________________________________ Message 2 _____________________________________ Time: 04:32:57 PM PST US From: Gary Vogt Subject: TeamGrumman-List: Baffles How not to do baffles. ________________________________ Message 3 _____________________________________ Time: 04:37:07 PM PST US From: Gary Vogt Subject: TeamGrumman-List: Inboard aileron support bracket is there any reason why the #10 screws can't be #10 bolts? It would sure make tightening them a lot easier. ________________________________ Message 4 _____________________________________ Time: 04:44:22 PM PST US From: Gary Vogt Subject: TeamGrumman-List: dented wing Three pics. I set a straight edge along the rear spar. It isn't bent. Just looks weird. ________________________________ Message 5 _____________________________________ Time: 04:56:05 PM PST US From: Gary Vogt Subject: TeamGrumman-List: Goldman This is for you. You now have competition for your wall mural. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message teamgrumman-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/TeamGrumman-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/teamgrumman-list Browse Digests http://www.matronics.com/digest/teamgrumman-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
