I was installing the elevator trim arms on a customers plane yesterday and ran into the same problem I did the last time I installed some. The pivot points on the elevator, the edge of the tab, rub on the trim arms. This caused the trim arms to work their rivets. One rivet was crowded out quite a lot. Both trim arms had marks on them where they were rubbing on the tab. Also, the trim arms come drilled for #30 (.128) rivets. The holes in the aileron trim tabs are around .150 in diameter. This is also what I've encountered on the last 3 sets of trim tabs I've replaced. At a minimum, the trim arms need to be drilled and larger rivets installed. I mentioned the misfit to Garner a while back, thinking it was the way the trim arm had been bent, but I think it's the tab the arm pivots on. Brake. Anyone seen this before? the brake mounting holes (bolt holes) have been drilled off axis. The lining rides on top of the disk. Nose gear torque tube. In Dayton, Garner had an overhauled nose gear torque tube assembly. It was all painted black. I asked him if he could powder coat the bearing supports silver on the torque tube. He laughed of course. I have one for the project plane. Out of curiosity, I thought I'd paint it two colors. Wow, what a pain-in-the-ass to paint. There are so many odd surfaces and places almost impossible to paint. After all the work masking and priming and painting, I think they look just fine in black. ------------------------------------------------------------------------------------- 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.
