I'm almost done with my shearwater hybrid and I'm looking for advice on how to fix an issue that has come up with my rear hatch. I cut out my hatches and built up the hatch assemblies, including attaching the doubler to the rear hatch cover. When i completed everything I noticed that rear hatch cover flattened out a bit and does not conform to the deck. There is a gap on one side of where the hatch is supposed to sit on the sill. I think that when the double was attached the hatch flattened out.
Any ideas on how to fix this? I saw a an older post that had a recommendation to put kerfs along the hatch and fill with thickened glue. If I were to try this, do I cut the kerfs through the plywood doubler and into the stripped deck? Thanks in advance!
