I'm having some trouble with this. Just started riveting my rear spar together with a pneumatic squeezer. I'm adding together the thickness of the material + half the diameter of the rivet head (470AD4's so 1/16 of an inch is what I'm adding) to determine the correct gap to set in the squeezer.
All of my rivets are coming out under-riveted, i.e. the shop head is not pancaked enough. I stuck a ruler to it and they are longer than 1 inch and narrower than the rivet gauge I have. The acceptable height listed in Section 5D is 0.50" to 0.70" for 1/8 rivets.
How do you determine gap length? If this is correct it could be that my way of measuring the gap is not precise enough. I'm putting a ruler next to it but because of the way the squeezer is designed I can't fit the ruler against the gap.
