- Riveted Front HS Spar together (HS-702 to HS-710 & HS-714); hand squeezed rivets. Not completely pleased with all rivets. Some ended up being a bit slanted. The AN470AD4-6's seemed a bit long. If I squeezed them to where they were the right depth then they were too fat (the bottom diameter was too large). If I squeezed them to where the diameter was just right they were too long. I found I happy medium. - Riveted the center rib and nose rib to the front HS spar (HS-404 to HS-405 & HS-702). These are the first rivets I have shot with my new 3X gun. I hated the way they turned out. I will be drilling these out and doing them again... Uggg!!!
