Allrighty, hope these do the trick.
Here it is being glued (laminated) with wood glue, It was a blazing hot day and hard to get everything lined up & clamped tight before the glue set-up. I got a 6' piece of 2" x 1/2" birch, but oak would be better. they cut it for me at the lumber store....(note: 2" lumber is really about 1 3/4")
That little 1/4" slip of wood that makes the slot is sold pre-sanded in 2' & 4' strips at Home Depot (I imagine other hardware stores do as well), it's fairly inexpensive for a small strip, and was used in the making of my pochade box. Each strip is 3" long, and I hand cut them to 1/2" wide to mach the thickness of the birch...making both of them 1/4" x 1/2" x 3". I found it easiest cut the pieces from a longer piece of wood clamped to the workbench...seems logical now, but took me a while, and bruised fingers from trying to hold little pieces of wood still, to figure that one out.
Close-up of the clamped end:
A very blurred image of what the end looks like:
How the t-nut sets. It's very important that when it's put in, the pressure of the tripod mount pulls it deeper into the wood....instead of pulling it back out (ask me how I know
). These are available at the hardware store, "1/4"- 20" x 5/16 in. (link in next post.)
edit to add: for the t-nut installment, you will need a 3/4" drill bit as well as drill bit the size of the outer dimensions of the threads. The 3/4" drill bit is needed to create a seat, or little divot for the head of the t-nut to sit down in so that it lies flush with the wood surface. It is epoxied in as well as hammered in.
Back side of the t-nut installment, this is where the tripod mount screws into it. There was some extra bits of birch left over so I used that, it was thick enough, and it didn't matter if the threading went into the center slot. If you don't have any scrap, then you will need some tough wood, 3/4" thick. Some use plywood, but I tore a piece up in a t-nut misadventure.
