How to Make a Ring Box With Concealed Hinge.

In this Instructable I will show you how i made a nice little ring box with a concealed hinge and magnets to secure the lid.

The dimensions shown are for the ring I was using for the purpose of this Instructable, you input the dimensions for your ring to suit.

I recently made a Solitaire game out of an Oak toilet seat lid I was given some time ago, I will be using the same wood for this ring box.

I will be using Vetric Cut2D for the sketch and creating the Toolpaths for this box.

The box will be cut out using a CNC machine.

Please ensure you wear the correct Personal Protective equipment for the task in hand:

Eye Protection

Ear protection

Dust mask

Wood stock, preferably a Hardwood(Depth approx19/20mm

Concealed Hinge( 10mm diameter on this occasion)

3/4mm Diameter Magnets 2mm deep

6mm flat 2 flute router bit

Fine sand paper

Oil to finish

On opening up Cut2D we create a new Set up, input Width/Height and thickness of the material here, also choose a starting point for our Zero on the CNC, I'm selecting centre of the workpiece as the starting point.

Create a rectangle, dimensions for this box are 52mm Width, 18mm Height and a 5mm radius fillet on the corners,

We create a 10.1mm circle as shown in the screen shot and centralize in a position approx as shown, this hole is for the Concealed Hinge.

Next create a rectangle 27mm width and 10mm height, radius the corners @ 4mm and centralize, this will be the pocket for the ring on the top and bottom half of the box, this is the design finished apart from making a mirrored copy in the space above the first sketch.

I will drill the holes for the magnets on the drill press.

We can now move onto the cutting section.

The first cuts will be the 2no holes for the concealed hinge, and we will be selecting pocket, these need to be at a depth of 11.5mm and we will be using a 6mm Flat 2 flute bit, we will be using the same bit throughout this cutting operation, using one G.code for 3 cutting operations.

We now need to highlight the bottom slot, again using the pocket function we make the depth 16mm same bit, the bulk of the ring will be in this pocket and a shallower slot for the top half of the box.

We can now select the next slot above and make this depth 10mm.

The next cut is a profile cut, highlight both outer rings, depth will be 19.3mm to cut right though the workpiece and select tabs to hold the cut piece in position during the final cuts.

Remove the pieces and sand as necessary.

We can now move onto finishing the ring:

The next step for me is to drill the 4mm holes for the magnets then oil both the top and bottom sections and let that soak in for a while, then we can install the concealed hinge and magnets, the concealed hinge should be a level fit and once happy with the position, the little grub screw can be tightened on each half.

Magnets are pressed in flush or very slightly below the surface.

The final thing to do is Laser a design onto the box, I opted for a Celtic knot.

There you have it, another cool project made from something as unusual as a Toilet seat lid which was going to be thrown out for trash anyway.

Thanks for looking and onto the next Project.
