Brief Description:	Rivet Front Spar Assembly
Today was spent riveting the doubler plates, nutplates and rudder horn to the front spar. I was able to use my squeezer for most of the rivets. When I got to the rudder horn area it was better to use the gun and bucking bar. I haven't done any solo riveting since my EAA sheet metal workshop early last year, so I proceeded with caution. I've observed that the larger the rivet, the easier it is to drive. At work I had the opportunity to shoot and buck some 3/16 in. rivets and it seemed much easier to do than the 3/32 in. Fortunately these were 1/8 in. protruding head rivets so it wasn't that difficult to do solo. Having the work clamped in a vise to steady it made it that much easier. That said, I still managed to pretty badly smash up one head. Back on the VS I put a smiley on a rivet head and I ended up making it much worse trying to replace the rivet. I ended up buying new parts. I'll seek some guidance on whether I should remove it or leave it alone. There's a little gotcha in the plans where you rivet the two upper doublers (R-607PP and R608PP) to the front spar. The plans call for AN470AD4-5 rivets. However, four of the rivets go thru the K1000-6 nutplates required a 4-6 rivet. the 4-6 rivets are called out on the middle doubler but not the upper doubler. The correct callout should be AN470AD4-5 (8 PL) and AN470AD4-6 for the nutplates (4 PL).
