The RC Allen trim display finally lost enough LED segments that it needed to be replaced. I have a spare, but before starting to fuss with a bunch of thin wires, I wanted to see how much slack in the wires there was to work with, to see if this would be morning surgery or all day surgery.
The tiny screws (smaller than #4 screws, use a #0 Phillips) go into washers and nuts. Only one came loose, using a finger to keep the nut from turning. What to do? Didn't see any 3/16" wrenches on the web, and I wasn't at all sure that a 3/16" socket would fit. Besides, that socket was at home and I was at the hangar.
I thought of making a 3/16" open end wrench from aluminum -- we're not talking serious torque, here, folks -- but then I got a better idea.
Took some brass tubing and tapped successively larger Torx fitting into the end. Wound up with beautiful, six sided socket about 2" long, perfect fit, and very thin wall. The other end is flattened in the vise to provide some finger grip.
Hope it works...
At one point, I saw replacement LED segments on the web but didn't order them. If I can find same again, I'll order, install, and again have a spare unit.
