Now, before I begin, I understand that Tupperdors, Coolidors and Winedors are the way to go. In fact, it's now how I store the majority of my cigars (Tupperdors, still lusting after a Winedor). BUT, I have a few cheap humidors that have sentimental value and that keep pretty decent RH (espcially with me living in FL). What I'm wondering is if anyone has tried anything to improve the seals or tried removing the felt bottoms and, I don't know, insulating them or sealing the seams from the underneath or adding extra cedar on the undersides so you don't lose space inside.

I realize the logical thing is to just make them storage for accessories but I thought I'd ask to see if anyone had ever tried tinkering with one to make it better.
