CH18 bottom problem

Posted by Ron C on Mar 14, 2005

I finally got around to stiching my CH 18 together and I'm having a problem. When I put the spreader stick in, and dry fit the bulkheads, the hull flattens out the hull between the bulkheads. As info, I cut the top panels down by 1 inch and made the same reduction on the bulkheads as well. I didn't change any of the dimensions on the bulkheads other than moving the notch down by 1 inch and cutting 1 inch off of the curved side as well. Using 24 inches at the spreader bar per info from an earlier post. any suggestions on how to get rid of the flatness in the bottom?
