Wanting to build a humidor...I have a few questions

What color wood do you like? Sometimes you can go to your local hardwood supplier and go through there stack of soft Maple and find curly maple. The figure in the wood starts to show when the log is being cut a certain way. It runs around 3.00 to 4.00 bucks a board foot. If you like dark woods, check out Walnut. Cherry is a nice wood too but it will darken considerably over time. If you want trays, I build them but the cost Spanish Cedar around here is around 7.00 to 8.00 bucks a BF alone. PM me if you like. I do build nice trays though. I do Mortise & tenon joints for longevity.

As far as a seal goes, I like making a groove in the frame before I miter the corners. Then after assembling the door, I use a foam tape that slightly raises out of the groove. This way its not too thick and has a clean look to it.
