Eric--That box is awesome looking. It screams ducking history to me. The thickness of the boards, fully 3/4", I suspect, makes me think it is quite rugged but heavier than I would want. I love the patina and the cradle. Man, if that thing could talk.
And Richard--your reproduction looks great, too. I especially like the boards across the bottom. The sliding tops tell me the owner of the original really put some thought into what he was doing. I would like to have shared a blind with that person, back in the day.
I just got the Porter-Cable dovetail jig, as well. It is supposed to make finger joints, too. I will try that out first chance I get.
I like to plane my wood down to a thickness of 5/8" - 1/2". I have an old Winchester shotgun shell crate I bought many years ago, and the wood is quite thin. I am inclined to think some of the old timers, not as concerned about the aesthetics, might have cobbed a gunning box out of something surplus like that. Who knows, maybe? I have toyed with the thought of using that old crate as a base for a box. All I need to do is add a top and some kind of cradle.
And looking at pictures from a previous thread about this, we notice how the boxes are so individualized. They must have reflected the thoughts and personalities of the men who built them way back then, some with angled sides, and some with drawers, other decorated with decoy head cutouts.
As for carrying handles, my preference would be for something mounted to the sides of the box, to avoid stressing the lid and associated hardware.
I received that new Gordon MacQuarrie book last week, and reading it there is a very brief mention of a shell box in one of the stories. No description was given, but my mind's eye immediately went to our gunning boxes we've discussed. I suppose that is the romantic lens I'm looking through when I think about this stuff.
Maybe one day, the grandson of one of my friends will pull a wooden box out of the closet and tell his friends that his granddad used to carry his gear in that box to go hunting, and I will rest knowing I had a hand in that memory.
