8/4 cases – Maple and fumed Eucalyptus with turquoise inlays

Previously I posted two in walnut/mahogany here are two in maple/eucalyptus with additional comments

Dimensions: 13” x 11” x 4 3/4”

Objectives and features:
  • Build medium sized strong cases
  • Find harmonious grain patterns and efficiency in a 2” x 8” plank
  • Home made veneer plywood panels
  • Wood hinges, latches, top supports and handle
  • Integrated lip for an air cushion during close and strength while closed
  • Through dovetails with a pattern to accommodate / hide kerf of lip
  • Inlayed turquoise bands
  • Flock both inside and outside of bottom panel

For the efficient use of the 2×8 planks I sectioned it lengthwise at the bandsaw for book matched sides and top/bottom frames:

Then, milled all pieces to 1/2” thickness. The top and bottom frames should unfold to book match and the show side of the box should get the frame piece adjacent to the box side.

For the top panels, this time I used some beautiful fumed eucalyptus over 1/4 plywood and a Roarockit. I did both sides of the panel from consecutive pieces from the flitch. It should look like a solid panel but be more stable for the large size.

For the top frames and handle I inlayed some crushed stone and posted: http://lumberjocks.com/MrLaughingbrook/blog/121457

An Incra positioner for machined dovetails (skip an 1/8” in the pattern to accommodate the kerf when I separate top from box), constructed the top and bottom as mitered frames and veneered panels, rabbited 1/8 to fit into the box, and glued it up:

To test the strength of the handle design mostly, but the whole box in general I filled a prototype box with bricks and went for a mile hike. All that mile I was frequently switching hands… The box, latches, hinges and handle held up.

I used the same claw pin latches described previously. They grab the hole in the box like a talon and the magnet is pretty strong. I don’t think anything could escape from the closed/latched box.

The hinges were installed barrel in mortise with CA glue then brass pins added. The hinges have a good 95 degree stop when mounted this way, but I later added folding stays to strengthen it.

The integrated lip presented some vacuum lock issue, so I loosened it. Then I needed to add alignment pins near the front of the lip to wedge the alignment when closed. In the side to side alignment of the top at the front of the box then even a 0.008” issue seemed obvious to me. This pic is from the walnut version, but same solution applied. Add the first pin on the short side to pull it back, then add the second to form a wedge for perfect alignment.

Comments welcome

Very beautiful, I really like the craftsmanship of both pieces and that the inlaid stone is conservatively used.

Besides being so great looking, they have quite a number of features. I appreciate the integrated lip for strength and you did a real good job with the dovetails for the kerf of the lip. Another favorite of mine are the latches.

Hopefully I can mimic some of the design into holiday gifts this year.

Steve.
