I also built one drawer divider and dovetailed it to the side as well as the vertical runner on the corner which encloses the 1 inch by 1 inch opening for the quarter columns.
The top has a cut away at a slope which allows light to show through the bottom row of the lattice.
I wanted to see if my guess was correct, it was not. I made the slope 1/2 inch back but it need to be more. That's why I built a prototype.
It also gave me a chance to see how the lattice will fit into the top. I also checked out the size of the front and side molding.
I now felt comfortable that I knew enough to build the upper case. I started with the sides which I wanted to be one piece. They are 16 1/8 wide by 41 1/2 tall. I have one board that will accommodate that size. It is too large to flatten with my machinery so I will have to do it by hand on one side anyway.
Unfortunately the board had a bit of twist in it, so I had to plane off quite a bit of get it flat. I needed to get the board for the side to 7/8 inch thick.
Once I got the one side flat I used my wide belt sander to flatten the other side.
I made a story stick with all of the measurements for the drawers and runners. I make a story stick for most projects, it makes it easier to transfer measurements.
The top and bottom are made from pine, I glued up two pieces to make the 36 3/8 x 17 1/8 inch top and bottom boards.
I laid out the dovetail pattern on the top and bottom. The tails are 2 inches and the pins are 1/2 inch at the top.
Then I sawed and chopped out the tails.
Then I matched the top and bottom to the sides and scribed the pins on to the sides. Sawed and chopped out the pins.
Everything fit together pretty good, I thought I would try it out in the the lower case. Now I know why they call it a highboy. The upper case is already pretty heavy.
Next I needed to make the drawer dividers (drawer blades). These have multiple joints on each end. A tenon for the vertical runners and a half dovetail to fit into the case side. Somewhat complex joinery. I used a dado to cut the tenons.
I positioned each of the drawer blades in the proper place and scribed the dovetail on the case side.
Then sawed and chopped out the dovetail socket.
This is a close up of the dovetail and tenon.
Close up of the dovetail fitted and the mortise and tenon on the vertical runner. This construction is solid and creates the 1 by 1 opening for the quarter columns.
Complete with a sample of the quarter column.
Next I worked on the drawer runners.
There in 1/8 shallow dados in the case side. They have a 1/4 inch tenon on the front which fits in a 1/4 in groove on the back of the drawer blades.
The runners are made from pine.
I also put a 1/4 inch groove in the back for the 1/2 inch pine back that I am going to make. Chapin made the back like a drawer bottom with a beveled edge on the back that slips into the 1/4 in groove.
The upper case I almost complete except for the runners for the three small drawers at the top and building lap siding for the back.
The build is coming along.
