One side makes another. After the curves on one side are completed, the first side is used as a template to make the second side.
After cutting the curves in the second side, 1 clamped the two together, and used a flush-cutting bit in the router to make the second side an exact match of the first.
A Trip to Through-Tenon Territory
The next step is where the dados in the case sides saved a tremendous amount of time and prevented the formation of even more grey hair. The layout for the tenons needs to match the mortise locations exactly.
At this point I looked at the three shelves, marked the best face and edge of each, and decided which one would be the top, mid
dle and bottom. I clamped the entire cabinet together and with a lumber crayon, marked the locations of the shelves in relation to the cabinet sides.
Some hand fitting would be needed, and putting a carefully fit bottom shelf upside down in the top shelf location wouldn't be a good thing. With the case together, I ran the point of my knife around the perimeter of each mortise, marking the location of the tenons in the ends of the shelves.
I set up a small plunge router with a fence set to leave the tenons slightly proud of the outside of the cabinet sides. 1 set the depth

1 cut the edge cheeks of the tenons with a dovetail saw, and used a jigsaw to remove the waste between the two tenons. With the end of each shelf housed in the dado these cuts didn't need to be pretty; I only needed to get material out of the way.
Before starting the fitting process, 1 took a chisel and chamfered the inside edge of each mortise, and with a piece of sandpaper I broke the sharp edge of each tenon to prevent damge to the outside of the mortises during fitting.
With a soft pencil, I made a series of hatch marks on the tenon cheeks and eased them into place. When I met resistance, I removed the shelf and examined the marks. The tight spots showed as smears in the pencil lines and I used a float to reduce the thickness until 1 had a good fit.
A Further Complication
Clearly in the grips of an obsessive-compul-sive exposed-joinery episode, 1 laid out each tenon end for a pair of wedges. Unable to leave well enough alone, I decided it would look nice to set the wedges on a slight angle, making dovetail-like shapes in the end of each tenon.
I marked the distance to the edge of each cut on the ends of the tenons with a combination square, then marked the angles with a bevel gauge and knife. The slots for the wedges are at a compound angle, but I only fussed
