The first packing box is complete! I do intend to add an oil finish to it, so it is "unfinished", yet its structure is complete. Its far from perfect, but it came out rather well.
Here's an image of the packing box from the book, followed by how mine came out:
Here you can see the clinched nails on the bottom's top, I tried to hammer them as smooth as possible but one may not want to put the most delicate of items in here without a liner. I'll do a post on clinching when I make box #2:
Here it is loaded up. It is actually quite ideal for books because it matches my golden moving tip: Don't put more books in a box than you actually want to carry. Its easy to pick a huge box and cram it so full that its ridiculous to lift.
Box closed. Its intended to be nailed shut, and true to the book, I drilled pilot holes for that. Modern folks would probably want hinges and a hasp added.
I have 2 more of these to make, plus a possible 3rd one which will be sized according to the scraps. I hope to add a little more detail with the different lessons learned and the basic operations involved with each iteration, so stay tuned and if you have questions about how/why, please leave them in the comments.
