<\/a>Oops. Notice the small, but still visible blemish near the most forward rivet.\u00a0 This came from the tungsten bucking bar pounding the reverse side of what we were processing.\u00a0 The bar as I held it was wide enough to span from one skin side to another. Drats.\u00a0 For later rivets I rearranged holding the bar parallel to the rib, not perpendicular to it as in this case.\u00a0 Hopefully this can be smoothed away with filler before painting.\u00a0 The only saving grace is this appears on the underside of the horizontal stabilizer.\u00a0 People will have to bend over and look from beneath to see it.<\/p>\n<\/p>\n

The small cells between the stringers, inboard ribs and spar are quite tight for my big hands.\u00a0 It takes lots of repositioning of the bucking bar to see well into those cavities.<\/p>\n<\/a>Here’s what it looks like on the outside as of Sunday morning.\u00a0 All the upper skin rivets are set (actually the bottom on this photo), the lower skins have been riveted to the forward spar.\u00a0\u00a0 The inner rivets and placing the rear spar up for next week.<\/p>\n<\/a>Upon inspection I found a number of scratch marks where the bucking bar had rubbed against the spar during rivet setting. This happened despite putting duck tape on the forward spar and the bucking bar for protection. My plan is to get a small Preval brand sprayer to prime over this spots before closing off with the rear spar.<\/p>\n<\/a>Another trick employed was fitting a felt chair leg cushion to the end of the bucking bar. When used in conjunction with duck tape against the spar, this seemed to eliminate any scratching.\u00a0 Another prime example of live, innovate and learn.<\/p>\n
