Again, I’ve done a poor job of updating in a timely manner. This post encompasses a couple of sessions from last weekend. During this time I have continued to prepare all of the wing skins for priming and riveting to the main skeleton.
I began by completing the deburring of the leading edge skins and ribs. I also prepared all the surfaces for priming with scotchbrite pads. When I scuff the skins, I use the grey scotchbrite pads, which are less abrasive than the maroon ones, and I use a very light and quick touch. The idea is to scuff, but not penetrate, the alclad. Leaving the alclad in place should increase corrosion protection.
Next up I set about removing the blue vinyl from all eight skins. I completely removed the vinyl from the interior surfaces that will be primed and using the soldering iron I removed the areas around the rivet holes on the exterior skins.
Finally, I began deburring the wing ribs. I deburred the outsides of all the ribs. I’m going to wait before I debur the insides. I lost my good deburring bit, and the countersink I’m using doesn’t work well if you are at an odd angle… and its a little bit slower.
I ordered a new countersink bit (2 actually) and I also put in an order to Aircraft Spruce for the Gertz Pitot tube bracket. I’m still considering whether or not I should install the landing light mounting brackets in the leading edge now or wait until I have the lights in hand and retrofit the leading edges. I made a post on Rivetbangers… so we’ll see what the guys think. I’ll post the thread here in a later post. Cheers -PLB
