The resolution was to remake them using thicker boards. Then after all the cutting was completed, I milled them to the correct thickness.<\/p>\n<p>This is one of those areas where it&#8217;s good to learn the lesson on a model.  It turns out that builders of the 1:1 version have reported similar problems making these bulkheads.<\/p>\n<p>The extra parts in the picture are for the hatches in the bulkheads. The bulkheads are intended to be watertight, providing a flotation chamber in each end of the boat. The plans define a hatch which uses a screw mechanism and gasket to close the opening. Or, one can buy a ready made closure from a boating supply outlet.  I chose to mimic the one in the plans.<\/p>\n<p><a href=\"https:\/\/www.bob-easton.com\/blog\/wp-content\/uploads\/2008\/05\/fm-knobs-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-thumbnail wp-image-37\"  src=\"https:\/\/www.bob-easton.com\/blog\/wp-content\/uploads\/2008\/05\/fm-knobs-1-150x150.jpg\" alt=\"turning tiny knobs\" width=\"150\" height=\"150\" \/><\/a>The screw is operated by a knob. Let&#8217;s make one. Of course it&#8217;s too small to operate like the 1:1 version, but can be made to look like it.<\/p>\n<p>This made a good excuse for doing some refurbishment of an ancient Unimat lathe. It will never be a good metal turning lathe again, but it&#8217;s good enough for this task.<\/p>\n<p><a href=\"https:\/\/www.bob-easton.com\/blog\/wp-content\/uploads\/2008\/05\/fm-watertight-bulkheads-assembled.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright size-thumbnail wp-image-61\" src=\"https:\/\/www.bob-easton.com\/blog\/wp-content\/uploads\/2008\/05\/fm-watertight-bulkheads-assembled-150x150.jpg\" alt=\"bulkheads and access ports\" width=\"150\" height=\"150\" \/><\/a>The port closures turned out very well.
