This started out as a piece of wenge, about 4 mm thick, laminated to about 30mm of plywood.
Apparently an offcut of something quite big.
I wanted to show that it was solid, not just veneer, so expose the 4mm thickness. Thus came the idea that the next layers down should also be about 4mm thick,
and of contrasting colours.
Hoop pine and jarrah were on hand.
The jarrah as donated was tongue-and-groove, and i wanted to use as much of its width
as possible, so the present top-edge, 5mm wide, is a former groove-edge.
Drew the design multiple times in Sketchup, and found that what looked best with
the 5mm outside edge was next-layers 6,7, and 8 mm. Thus the size of the outside is size-of-wenge + 5 + 5 + 6 + 6 +7 +7 + 8 + 8, totalling about 270×165 mm.
The other part of the design stage was: with all those little 4mm layers,
how are you supposed to grip the lid ?
Well, that’s why I call it a gizmo box: in one end is a spring that lifts the lid (pic 3, slider moved across,
lid is lifted just enough to get fingers under).
I’d been wanting to do a spring-catch for a while, but had in mind one that kept a box Closed,
and instead, this Opens it. Probably a safer way to go, because if the gizmo fails,
you still can get this lid open. You just need smaller fingers than some of you jocks have !
If a closing-latch failed, you might have to wreck the box to get it open. Not Acceptable.
Finished the hoop pine exposed surfaces before gluing up, with water-based poly, to
retain the paleness. Finished the jarrah with oil-based poly, because I wanted More colour.
Finished the wenge many many many times, and sanded back a few, with oil-based poly.
That was during some of the driest weather we have had around here.
But, after about 2 months, and the box was almost all together, it rained a solid 2 days.
The formerly nearly-invisible crack in the wenge opened up. Blast !!
A bit more oil-based poly after assembly, to get the same satin on it all.
As you can see, I did remember to photo the gizmo parts .. in case anyone out there
wants to give this a try.
Definitely try it with old pine drawer-sides, before making it in your good wood.
