Brief Description: Deburr skins and C/S LH rear and trim tab spars
Recently I've been sidetracked with getting a porch cover rebuilt in my front, so I haven't had much time to spend on the airplane. I'm going to do it myself with help from a neighbor who has built these in the past. I'll be saving about $1500 this way and I'll use the savings for my wings.
Today I finished deburring the upper skin. I seem to be the slowest person in the world when it comes to building an airplane because I do a lot of checking while I work. While I was deburring the holes I found one with a nick in the bearing surface. It was a bit subtle and I had to look through my jewelers eyepiece to verify it. I'm not sure if it was delivered like that or I nicked it during handling. In any case, I'll fix it by drilling a #30 oversize hole and using an oops rivet (NAS1097 rivets). No one will ever know the difference when I'm done.
In a previous post I detailed my concerns about the countersinking of the rear spar at the trim tab hinge. Well, I did the countersinking operation for that and the trim tab spar and it did not result in a knife edge with the C/S going into the hinge itself. However, there is almost no bearing surface left. However, per section 5.5 of the plans, this is acceptable. Looks like I was concerned about nothing and I won't have to bond the hinge and the spar together as I had initially thought.
I'm ready to prime this batch of parts. I kept the batch small because it's my first time in a couple of years priming anything. I've got new Akzo ready. The spray booth is in need of some repairs but I think I can do that tomorow morning and still get in the priming session.
