I have been battling with a few of the rivets in step HS 8-10 where you rivet the ribs to the front spar. A couple of the top and bottom rivets I have had to drill out a few times. As a result of drilling out the small tabs on the ribs are bent up slightly. I have tried the "rubber tube" technique to press the tab against spar, however, I still can't get them to set correctly. I'm wondering if there is any reason why I can't reverse the direction of these few rivets so the manufactured head is on the inside if the spar. This will allow me to use my squeezer to pull on the manufactured head pulling the tab towards the inside of the spar and then, the ram squeezing the shop head on the front of the spar. I believe watching and controlling the ram will give a better result. I have checked clearances and the manufactured head on the inside of the spare is shorter than an ideal shop head. I can't see how this will effect the clearance riveting the skin on later.
