As I said in the project post….
In 1969 a group call King Crimson recorded an album called Court of the Crimson King. This box is named after the title track. As well as the King himself there are several other characters in the song including; the Purple Piper, the Yellow Jester and the Black Queen. I have been struggling for many years to design a box which features all of these.
Michelletwo came up with the inspiration in her Color project post. The slots in this form are ideal to place the colours mentioned above, behind. After a few hours fiddling around in TurboCAD I came up with a 3D model giving views like this.
View from side.
Some decisions were easy. Padauk for the main body. Purpleheart, Pau Amarello and something Black for the three other colours. Box type and construction method, Shell and EZ mitre. Then things started to get tricky.
Initially I’d thought of two layers or shells. 3mm thick Padauk for the outside shell and the same thickness pieces of the other woods for the inside shell. Having two shells made from lots of separate pieces, some not immediately connected on all edges to others was going to be inherently weak.
Whilst deciding whether I had enough Ebony to make it this way it occurred to me that I had some black dyed Birch veneer left over from other projects. If I made it three layer instead of two I could use veneer for the two other colours. purple and yellow. These could be attached to a contiguous Sycamore inner layer. Giving the required strength to the design. In order of layers it would go like this
Layer 1, 2.5mm skin of Sycamore
Layer 2, with 0.5mm veneer added
Layer 3, 3mm Padauk added
Fine so far. As it was going to be an EZ Mitre box I could veneer straight on to the base, Sycamore layer. At first I thought thats where I would mitre it, giving me a shell like the second picture. I’d then make up a separate Padauk shell and machine the slots into it. Then glue the two together.
It didn’t take long thinking this one over to come up with two shortcomings of this approach.
1. The two shells might not fit together very tightly.
2. Horrendous mental images of pieces flying everywhere as I table sawed through the Padauk shell.
I was going to have to layer the Padauk on the veneer layer and mitre the whole board.
Hold on though. The central slots were easy as they were vertical throughout their whole length but the ones either side were vertical on the top but angled at 60° on the sides. I had trouble reconciling this in my mind but it had to be so. Reorganising the TurboCAD model into a single sheet showed me it must be so.
So, happy that I’d seen it in 3D (but still inwardly struggling with it) this was how it would be.
Stay tuned for part two when I finally get to make some sawdust.
Be seeing you.
