Horizontal Stab. Completed! Thanks for everyone for their support, it won't be completed without your help!
Some minor issues popped up on completion of the HS.
1) I have a pneumatic squeezer and sometime I am getting offset shop/manufacture head result (see photo), I wonder what am I doing wrong here. I am still getting various comments on these rivet, whether I should replace them or leave them...
2) Sometimes the shop head is crooked and expanded the hole into an oval shape. If I replace the rivet, the replacement rivet's shop head will be crooked as well since it will try to fill the oval shaped hole...what should I do?
3) One of the rib to spar attachment leaves a gap, is this acceptable, can I do anything to avoid it? also, if I am to fix this, how do I do it to avoid the gap when I squeeze those rivets?
4) When I buck the 4-5 rivet, sometimes it forms a "skirt" shape shop head. I found the size 4 or above rivet is very hard to buck, I often has to use all my strength and often hard to control the bucking bar. Am I doing something wrong here? Is my 3X rivet gun not producing enough 'power'?
5) On my VS, attachment between the front spar and ribs, I crack one of the hole when I drilled out the defective rivet. I then tried to enlarge it to a size 5 hole but it still doesn't cover the crack. I decided to drill a new hole next to it and leave it open. However, how do I repair the crack as I don't think I can leave a crack open.
Thanks!
