Thanks all, you've given me the bug to build. Now I need to find materials. I've tried a dozen lumberyards, even 'Specialty Plywoods', and have not found any type of 3mm (1/8") waterproof mahogany. I've found some on the web, but $75 or so for shipping is prohibitive. Any suggestions on how to find it locally? I'm in St Pete, but Ft Myers or Orlando would be reasonable.
