Title: Top Skin
11/25/2005 I plan on installing the hidden rudder belhorns, and a kind fellow builder was nice enough to send me a digital copy of the plans while I waited for mine to arrive in the mail. The only part I needed from those for now was the routing of the rudder cable conduit, which is pretty straightforward - you just run it straight from the entrance location in the wing root to 1.2" in from the trailing edge at WL169. It should come just to the corner of the aileron cutout without actually touching it. 11/23/2005 (4.5 hours): To prepare for glassing the top skin, I installed the rudder cable conduit and cleaned up the leading and trailing edges. I also cut the notch for the flox corner around the attach bolt access hole. Finally, I sanded the spar cap flush with the top of the wing. I definitely need to get a new belt sander - this took 3.5 hours to do with my piece of trash. The spar cap wasn't bad, just a little proud in spots. 11/25/2005 (5.5 hours): This step was fairly straightforward, just time-consuming. I took a little longer wetting out the glass than when I did the bottom, because I had to use the brush a lot more. "Dump and run" isn't well suited to steep curves or vertical surfaces, and the leading edge is much more curved on the top than the bottom (naturally). Anyway, no surprises - micro, fabric, epoxy, squeegee, peel ply, plastic, and squeegee with hair dryer. I clamped an aluminum straight-edge on the trailing edge. The extrusion John Slade and I bought when he was here didn't work out - it got covered with epoxy and I didn't have time to clean it off completely. I bought some replacements, just right-angle aluminum extrusion. I used spring clamps and clothespins to hold them onto the trailing edge and keep it perfectly straight. Should do the trick. 12/6/2005 (2 hours): I had neglected to install all of the reinforcing layups, so today I took care of those. These included the BID triangle at the outboard edge, the two UNI pieces near the outboard attach bolt, and the three UNI strips over the inboard attach bolt and onto the top of the wing. I also installed the two 2-ply UNI strips that make a "V" from the outboard attach bolt onto the top of the wing. These are actually from step 9, but since I was here it made sense to just do them all at the same time.
