Primed the countersunk crossmembers on the fwd fuselage. Then cleco'd the F850 bottom skin in place. I used 3 blind rivets in the aft 3 holes and bucked the remaining. As I was preparing to rivet the remainder of the F850 I noticed that I wouldn't be able to install the gear tower to F822 floor rivets if I closed out the F850...not good. I must have confused the which rivets get left out and I riveted the fwd section of the tower and left cleco's in the back, reverse of what I should have done. So my options are to drill out the fronts and rivet the back or rivet the back and see if I can use blind rivets on the short section of the F850 that can't be bucked unless I drill out the front gear tower base rivets - confused yet? Needs less to say I'll be working on something else over the next severals days while I sort this out.
The red box shows cleco's where rivets should go and the area shows rivets where clecos should be - du
