Finished Drilling Main Wing Skins to Skeleton
First today was grinding out some notches on the wing stand so the outboard leading edges would fit. This was a huge pain because I had to pull the wings out of the stands (with Jaime's help) and lay them carefully on the floor whilst I ground away on steel with the Dremel tool. What a pain, but necessary. Do youself a favor and go ahead and make sure your wing skins will fit. You need about a half-inch clearance outboard of the spar web.
Then I thought I would entertain myself by checking for twist in the wing before drilling...
Well, it was right on the money. People who think you can build a lot of twist into these wings are in my very humble opinion doing something wrong. This thing was dead on, within 1/100's easily. Just for kicks, I unclamped the inboard edge to see how much I could actually twist the wing. Well...you really can't. Maybe a 2 or 3/100s or so, but that's it (this is with all the main skins clecoed on).
Well, I guess it's good to know that it's dead on at least.
After checking for twist I proceeded to drill out all the holes. This took forever and a day since you drill out the holes, then you must move the clecos and drill the holes the clecos were previously in. Then, per the plans, I removed the bottom skins.
Tomorrow I'm hoping to build the leading edge cradle and get the leading edges clecoed together and clecoed/drilled to the rest of the wings. Should start really looking cool by then.
