Okay, I triple checked the measurements for the Chesse 16 I am building, made my cut panels and sanded them down to the lines drawn, however, when I layed the bottom panels out, they did not seem to line up properly? Meaning, at the widest end they match up edge to edge, but in certain spots along the way there is a gap of up to 1/2 inch and then it comes back together, before spreading out again before the end? I cut them at the same time as recommended, so each panel is identical. Without seeing this, did I screw up somehow, or does this sound normal? When I stich the panels together will the close the gap and come together? If not, is there anyway to repair a half inch gap as I described? HELP.
