Yeah, Tom. I cut the dovetails super-tight in ¼ inch material, then use a small rasp to loosen them up enough that they fit nicely. I almost always groove in the (usually floating) bottom too, which adds support and helps me get the box square. The lid will either be sliding or glued on and then cut and hinged, or piston fit. Even ¼ inch pine is pretty dang sturdy, though. I wouldn’t have trusted some of these boxes when I was starting out.

May you have the day you deserve!
