I've started building the cajon. The top and bottom are 3/4
prefinished birch ply; the sides and back are 1/2". The different
thicknesses were mostly chosen because that's what I had available in
scrap lumber, but it also allowed me to feel more comfortable about
rabbeting the top and bottom to accept the side pieces and the back.

The rod, by the way, will have snare wires attached to it and the
knob will allow me to engage the snares or disengage them.
The back also fits into rabbets. I decided to attach it with pocket
screws for now. . If it seems like there is air leakage around the
edges, I'll either glue it or caulk the joints.

As predicted by some of you here, it feels more than stout enough,
even without the front piece.
Looking good.
You may be aware of this but the thicker the wood, the higher the pitch.
That's one reason for having a thinner "batter" side. Also, think about
a port. Do some reading on it. A port with usually add some low end
and resonance.
The front piece (the "tapa") will be 1/8" birch ply, because that's what
they had at the crafts store near me.
Funny you should mention a "port", I was thinking about that, even
though I have not seen any cajons that have one. I found a floor drain
flange at HD that mates with 4" PVC pipe. I might give it a try,
depending on how the cajon sounds once it's complete. I see that someone
actually sells an add-on for cajons, but it's only about 5" long.
I also wondered about possibly adding piece of ply inside, parallel to
the tapa, extending from the top of the cajon almost to the bottom,
giving the air a longer path to the hole in the rear.
For me, this may be one of those "getting there is half the fun"
situations. It might sound great without any tweaking, but if not (which
seems likely), I'm up for some experimentation.
