Zank, are you building a humidor for the art and satisfaction of building one? If not why not just buy one that is already done. It doesn't have to be a Chinese made one. I had a custom cabinet and and small walk-in closet humidor both built and after it was all said and done - I have a ton of money tied into both of them. Not sure what your carpentry skills are but a lot goes into planning these properly. Don't go cheap on on the things that you shouldn't . In the end if your building one, you want to be proud of it and don't want to kick yourself in the butt for not spending the money on the things that you should've of. Just saying brother.
