Hello everyone, so I'm pretty new to woodworking, less than a year and really like to make dovetail boxes. My shop is not heated and I live in the north east. The supplier I buy hardwood from keeps it in an unheated building also. After I put the finish on I have to bring the project into my house to dry and almost without fail, the next day the cover will be cupped. Sometimes pretty severely.
I've tried single piece lids and laminated ones and seem to have the same problem either way. I'm wondering if this will always happen because of the temperature and humidity change or if there is something I can do to stop it? Any help would be much appreciated. Thank you
