In the shot above you can see where I placed my bench dog holes; this is my comfort zone and its what works for me. Id suggest clamping a baton across your bench top and see wheres right for you. Maybe clamping a baton across the bench will alchoices be enough for you and youll never have to scar your work bench...in my world I dont mind a few holes in the work surface.
So with that I carefully draw a square line and mark with an awl the locations. I also mark off a hole in the block on my front shoulder vise; this is used sometimes to hold small pieces across the bench top. Ill probably add three more holes in line with the left hand side of the vise, but for today these three will suffice. (Make sure before you start boring youre not in line with the vice bolt or screw!!)
Im using a couple of Bench Pups from Veritas; theyre the round brass type 2 3/8" long. I also use a pair of the 4 3/8" ones but theyre still sitting all snug in the holes on my bench top back in the city. 
With the third hole drilled Im ready to get back to work and surfacing the four pieces of the project is next on the list. As mentioned Ill lay a thin baton of hardwood across the bench top and work the boards flat, checking as I go. 
My shop made winding sticks also made the journey home and theyre the perfect tool for the job of checking this Khaya for any humps, valleys or wind. 
In no time at all Im back on the shooting board taking incredible shavings in the end grain. The 5 1/2 is a wonderful shooting plane and this minimal shooting board is working out better than I anticipated. (Just to answer the inevitable now instead of later...no-I wont be getting rid of my fancy shooting board back in Toronto nor will I stop using my dedicated No. 9 Iron Miter plane! This is good and working well but that duo are the cats ass when shooting)
Four pieces, square and smooth Ill sit them on the bench top and take a few steps back. Im already thinking about adding to the design, perhaps a small frame to hold the carcass? Theres still some long skinny strips of Khaya and will think more of the piece while Im marking out the dovetails.
The Tite-Mark again finds its choice into my hand- this time the perfect application. Im laying out simple through dovetails, nothing too fancy, I am still on vacation over here! 
I like to clamp both pieces together when I lay out my tails as seen in the next photo below...This will obviously insure continuity between the top and the bottom and will speed up the process a little as well.
I walk the dividers across the tail board and draw in the lines with a pencil and my dovetail marker. Youll notice that I divide the board into seven even sections and then when I start sawing Ill skip the middle one. This is something Ive been doing lately, (perhaps a nod to my Krenov admiration?) I love the look the two trios of tails make. (my tool chest and small wall cabinet I made for my book projects also had this same treatment) With that its time to cut dovetails and my small rip saw seems to really like this hardwood. Khaya is a great wood for hand tool work except sometimes when hand planing. The ribbons in the wood grain can reverse and bend which in turn can result in tear-out. This is easily remedied by some sanding in the final stages but Im hoping to avoid it if I can.
The tails are cut first in my world but you can start with the pins if youre so inclined. From dovetail saw to fret saw I wander and in no time at all Im reaching for some chisels to clean out the waste. My detail chisels which I cant say enough about are alchoices close by.
With the tails cut and clean its a good time to break for the night; were having a campfire and I better get some kindling together. The beauty of the wood shop-alchoices lots of waste to get a good campfire going...
...Morning comes fast and first up is to transfer the tails over to my pin board; I use a thin Paul Bebee knife to reach deep into the corners. You may have noticed I didnt use the 140 trick when beginning these dovetails Im not sure why I didnt other than to say I may have been thinking this little project was destined for the wood shop. If this was a drawer for a client then I would have cut the shallow rabbets into the inside end of the tail board to make life easier when transferring the lines over. (if youve never heard of the 140 trick then you have some homework for tonight...look back through my older posts to find the method)
Again from the dovetail saw to fret saw dance Im back to the chiseling and ready for a dry fit.
At this point the box is ready for glue; Ive been thinking about the long strips of Khaya left in the off cut pile. Maybe a frame assembly to cradle the box? A trestle type affair dictated by the stock in question. In my work space Im able to create and design without any guidelines or rules save the lumber Ive chosen (perhaps foolishly) to work with. Sometimes the pencil and paper are better left on the shelf and we can meander through this creative process with only the wood to guide us. It can be quite liberating stumbling through a building process when time is our only real investment. Ive been enjoying myself over these past two days and really most of my time was given to setting up the work space. The hardwood owes me nothing but Im going to do my best to lure it into some form I can call my own. A cantilevered box over a thin double trestle?This evening Ill do some more measuring and continue a little further on, down the path.
For now though...theres an old crow waiting hungrily, from his perch in yonder tree...
