I originally posted about this in the "Magazine box... desktop cannon"
To recap, the idea was to build a small "ammo crate" type box from ¼" x 1½" poplar strips available at Lowe's. The box would have a 5mm cotton rope handle on each end (Hobby Lobby). Inside dimensions would be 4" x 7" x either 1½" for a single board height or 3" for two.
I decided to go with the deep box for now, I'll probably add a flat box eventually.
Got it all cut and laid out for scale along with a sample of the rope for the handles (except in the pic I have the short end braces for the flat box instead of the longer ones I ended up using). This was as far as I'd gotten in the other thread.
I started assembly with the top and bottom, glued up on a flat aluminum slab and weighted with lead ingots. I wasn't too concerned with a tight fit between the boards, this was supposed to look like a crate not fine joinery. After those could be moved off the plate, I moved on the the front, back, and sides.
(You can't see it but there is a piece of wood underneath the aluminum to keep it up off the table top.)
It's solidly glued and isn't coming apart, the tacks don't really do much other than give it the appearance of being nailed together. There are a bunch of them, all in tiny pre-drilled holes.
Front, back, and sides assembled onto the bottom.
End corner braces and ropes installed, and lots more tacks (bottom too). Not in love with the hardware (Lowe's), but it's what was available.
And finally this morning, a little stain to give it some "age" (assorted cannon/mortar projectiles included to keep this on topic) . . .
The hasp is a little too ornate, if/when I find a more appropriate one in the right size that will change, but otherwise I'm happy with the way it turned out.
