This build started a little differently in that I started with one element and worked from there.
I had two 24" long wane edge bubinga cut-offs from a recent table build and thought they would make an interesting base for a box.

The 45-degree angle of the edges was a bit much so I reduced that to 30 and established a back straight edge for a reference point. Then mitered the corners and glued up with epoxy. This gave me three corners with a perfect grain match.
There was some mismatch so I cleaned that up with a die grinder and used a wire brush to introduce some texture.

At this point I made a full-size drawing and a foam core model of the carcass and top. I was originally going to veneer the pyramid top and mocked up how I was going to orient the grain.

Basically that looked like too much work so I decided to use solids https://forum.canadianwoodworking.com/images/smilies/smile1.gif
By drawing the 1" rise I could measure the length of each triangle and create templates for the end and side pieces. The templates are visible on the left side of the image..
Resawed and glued up a board of birds eye maple. This is where my high school trigonometry failed me, I couldn't figure out what the angle should be to glue the parts back together, sigh....
The parts were too small to cut the angles on the table saw without a sled. So instead, I set up a ramp on my disc sander and through trial and error determined the correct angle.

With all four parts taped together there was still a slight mismatch so I did the glue up in two stages, one side and one end each. Trued those long edges and did a final glue up.

The parts are 3/8" thick so I didn't think they needed splines, etc.
To cut the angles on the carcass parts, I made a bed to attach to the SCMS and installed a horizontal hold down. I used that hold down to cut one angle and then flipped the parts and simply clamped them to the bed's back fence to cut the other angle.

Turned and installed an ebony handle....
Oil and post cat lacquer finish...
