We cut out the old blown out corner and made it a seperate panel. This adds the number of panels we need to  cutout and making the pattern more complex, but it lets us eliminate the corner seam.  More testing tomorrow&#8230;.<\/p>\n<figure id=\"attachment_700\" aria-describedby=\"caption-attachment-700\" style=\"width: 150px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/jpaerospace.com\/new_wordpress\/wp-content\/uploads\/2009\/08\/inserting_inner_tube.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-thumbnail wp-image-700\" title=\"inserting_inner_tube\" src=\"https:\/\/jpaerospace.com\/new_wordpress\/wp-content\/uploads\/2009\/08\/inserting_inner_tube-150x150.jpg\" alt=\"Inserting the airbeam inner liner.\" width=\"150\" height=\"150\" \/><\/a><figcaption id=\"caption-attachment-700\" class=\"wp-caption-text\">Inserting the airbeam inner liner.<\/figcaption><\/figure>\n<p><a href=\"https:\/\/jpaerospace.com\/new_wordpress\/wp-content\/uploads\/2009\/08\/pressure_test.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-thumbnail wp-image-701\" title=\"pressure_test\" src=\"https:\/\/jpaerospace.com\/new_wordpress\/wp-content\/uploads\/2009\/08\/pressure_test-150x150.jpg\" alt=\"Pressure Testing\" width=\"150\" height=\"150\" \/><\/a><\/p>\n<div class=\"mceTemp\">\n<dl id=\"attachment_701\" class=\"wp-caption alignleft\" style=\"width: 160px;\">\n<dd class=\"wp-caption-dd\">Pressure Testing<\/dd>\n<\/dl>\n<\/div>\n<figure id=\"attachment_702\" aria-describedby=\"caption-attachment-702\" style=\"width: 150px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/jpaerospace.com\/new_wordpress\/wp-content\/uploads\/2009\/08\/always_more_sewing.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-thumbnail wp-image-702\" title=\"always_more_sewing\" src=\"https:\/\/jpaerospace.com\/new_wordpress\/wp-content\/uploads\/2009\/08\/always_more_sewing-150x150.jpg\" alt=\"Always more sewing...\" width=\"150\" height=\"150\" \/><\/a><figcaption id=\"caption-attachment-702\" class=\"wp-caption-text\">Always more sewing...<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>We put everything we learned from the 5.5 psi test into the large Ascender rib airbeam.
