Hi Ian,
Not sure if Grumpy is on TeamGrumman-list. I saw this in the parking lot of the
new Mel's Diner in Auburn, CA.

Subject: Elevator trim arms, brakes, nose gear torque tube.
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.
