I can buy a series of 4 inch thick rings and machine them flat, glue them together to create a sphere. The rings can be machined individually so when glued together I have a sphere. The beauty of this is I can have additional thickness where I need it, like the hatch land. The ring that makes up the hatch land can be thicker.</div><div id="yui_3_16_0_ym19_1_1499906747909_2507" dir="ltr">Any reason this is a bad idea.</div><div id="yui_3_16_0_ym19_1_1499906747909_2507" dir="ltr">Hank</div></div></body></html>
