In making a little box to hold a Christmas present for a friend, I took the opportunity to experiment on how best to offend all the woodworking purists at once. So I came up with half tails on the sides and a giant pin on the front and back.
The bottom is rabbeted into the sides only, and oriented so the long grain runs front back. I did this to avoid cutting stopped rabbets on the front and back. The mahogany in question is very old and very dry (read: prone to chipping). What looks like a gap on the bottom left shoulder above is actually just some cosmetic chipping.
I have a bunch more of this reclaimed mahogany. Most of it has cupped somewhat, and it comes to about 5/8 thickness when re-tried. It’s good practice on hardwood dovetails and will be the accent wood in my new tool chest.
Merry Christmas, and whatnot.
