When glueing braces or the top/bottom/sides the wood should be dry. The current dryness of the top/bottom/sides will be "built in" the guitar by the glue. If the air and the wood is damp when glueing, later dry conditions on the glued guitar will make the wood shrink with all kinds of problems as a result.
I'm thinking of buying a drying cabinet like this one (Nimo ETS 1100, 1140 x 595 x 335 mm) big enough for most guitars.
Before gluing braces/top/bottom/fretboard my plan is to put the woods to be glued together into the cabinet and let it dry in 50-60 degrees Celsius for an hour or two. That will keep the moisture level low no matter what the moisture level is in the air that day and make the guitar more resistant to dry conditions when finished.
What do you think about that? Anyone doing this?

Makes sense.
When you think about it, all that matters is that the woods used in the bracing of the top, back and sides should be between 40% - 50% RH when they are being glued, with a similar RH when the box is closed.
What the humidity in the rest of the shop might be during sawing, and planing operations is irrelevant..
Keeping the parts in a cabinet such as the one shown above would certainly be one way to achieve this.
They are not cheap however. The one shown above retails in GB at almost £400 GBP
Yes, expensive. Had to order one and I just did. I HOPE this will be a great addition to the workshop.
