Deburred all of the holes and sprayed the trimmed edge of the nose ribs with rattle can primer. I then riveted them all in. Between the alligator squeezer and C yoke squeezer I was able to squeeze all but 1 rivet (where the strut attach bar sits). I prefer squeezing over trying to use the … Continue reading
All of the nose ribs are drilled. I tried the string method this time and while it seemed slower than using the tool (made off the tip rib), hopefully the results are better. I used some 20 lb. test fishing line I had laying around as well as some plastic beads from the tackle box to … Continue reading
Got all of the center ribs trimmed, drilled, deburred and clecoed in tonight. Everything fit perfect. I used small pieces of .032 clamped onto the rib at the rear spar to simulate the wing skins, this makes it simple to align the rear of the center rib. I checked spar web distances, level front to … Continue reading
The main spar was added to the jig along with the flap and aileron supports. Similar to the rear spar, the distance from the main spar web to the guide wire was made constant from root to tip as well as level across the spar. I set up my long level, shimming with blue paint … Continue reading
I decided to go ahead and rivet the aileron pocket ribs in before putting the rear spar in the jig. I spent hours on my back doing this on the left wing, it’s much easier to do on a table. The only adjustment I made was to trim the tip pocket rib about .04 since … Continue reading
Drilled all of the attach angles and match drilled the strut attach steel to the spar. Cut the spar web flange to allow the strut attach to clear. I placed a rivet on the lower capstrip too close to where the strut attach steel lays and had to add a slight chamfer to the steel … Continue reading
Marked the rib attach angles on the main and rear spar for drilling. I marked a line .19 from the edge of the angle to ensure proper edge distance for the 3/32 rivets then eyballed the other marks. I am trying to be more effcient with my time on this wing, ie. the rivet holes … Continue reading
Well, here we go again. I am hoping the right wing will go faster. The root end of the wing will be on the opposite side of the jig, so that the bottom faces towards the front of the garage. I began by resetting the guide wire. It’s simply a piece of .032 stainless wire … Continue reading
I finished riveting the inspection hole backing rings in. The only trouble I ran into was a single nutplate was interfering with the pully at the spar joint. I drilled out the rivets and replaced the K1100-6 with another non-dimpled nutplate…..that was shorter by just enough to clear. I’ll need to remember to use a … Continue reading
Started getting the bottom skin riveted on. Steve came over to help, it’s much easier to do with 2 people. There are a few places you need to be a contorsionist to get to. We tied up the bottom end of the bottom skin to the rafters, you’ve got to be careful not to kink … Continue reading
