I am a wood worker with a contract to build a large humidor for the cigar room in a restaurant. The piece will be 9' high and 12' wide. have a glass front display case with cigars for sale, and 48 locked drawers that will be rented to the restaurant's clients to keep their private stash. There will be many challenges in engineering this unit, including adequate humidification, air circulation, and sealing the many openings. I have some Ideas about the solutions to these issues, but not enough experience to feel confident that they will result in a successful piece. I would like to talk to someone who has had experience designing and or building a piece like this... anybody out there?
