Spacing Between Box Top and Bottom
I wish to make a box of 5 sides (no top) out of 1/2" near furniture grade (i.e. sanded) plywood.
No attaching hardware to form the shape will be of issue. In other words I am gluing and nail gunning (sub-surface).
I will need two of these, one about 1/2" bigger/fatter/taller (i.e. the box top).
The box top, the larger of the two of course, may not be bigger than 36" L X 12" H X 24" D, but around that size.
How much space should I allow between the outer edge of the box bottom's sides, and the inner edge of the box top's sides, which of course lies on the outside portion of the overall pair of 5 sided objects.....
an 1/8"...a 1/16" ?????
In other words, how much "play" do you think is a good rule of thumb here, allowing for changes in humidity across seasons?
The contents of the box are light (clothes) such that the box's dimensions for all intents in purposes are not changed (i.e. the wood is not warped) by whether or not the box will have contents.
The box is out of sight; it's for storage, so appearance doesn't matter. Accordingly, is there anything I should treat the wood with to help keep it dimensionally stable?
The wood need not be cedar. Moths are not an issue.
