Wing tip ribs
Got home early after the yearly parent/teacher conference. I did another session with the labels and had one successful out of 3. Not bad. After thinking about it overnight, I decided that the fuser (a.k.a. laminating machine) is getting too hot. That’s why the first session worked well yesterday and the next two didn’t. The lettering is sticking too well to the mylar. I’m going to keep chipping away at the labels in short sessions every day. Hopefully after a week they’ll be done.
I worked on the wing tips some more. I sanded a couple spots down a bit more for a better fit and drilled out to #30. I cleaned up the notch of the cut out for the ailerons. I also fitted and drilled the ribs that reinforce and close off the trailing edge of the tips. The last task was to drill out the holes in the skins to #28, deburr, and dimple. Just a couple more things to do on the wings and I can move them down to the hangar.
And one of those last things is installing the pitot tube. Unfortunately, the Gretz pitot tube does not fit into the Gretz pitot mount. Not a big deal. The instructions suggest grinding it down with a Scotchbrite wheel. The pitot tube is such an odd shape that it’s difficult to get all surface in contact with the wheel. I had to remove the safety cover. Once I finally got them fitting together, I discovered the screw holes don’t line up. Come on. These two parts came from the same guy and they don’t even come close to fitting together. Time to haul out the Dremel.
I also took another look at the fuel flow sensor. I think using a 45 or 90 degree fitting on the outlet will solve the fit problems. I’d prefer the 45, so I’ll try that first. Almost time for another Spruce order.
