Several people have made comments about wanting to build a humidor. Way back in 2012 I posted a fairly detailed account of what goes into building one of my humidors. There are several ways to go about it but this is how I do it. I've taken the liberty of reposting those old threads so you can get an idea of how it works. Hope this might help a little.
I'm pretty jealous, like I said, I do some wood working, but my set up is very limited in comparison. When my wife and I talk about our dream home, I always talk about having a shop... one of these days.
