Ring Box part 2

In my last post, I showed the process of building a small wooden engagement/wedding ring box. Obviously it needs some lining to be fit for use.

The original sketch had a note next to it about an LED in the lid which I definitely wanted to do, but there's some space constraints to consider, namely where to fit batteries in the box while still keeping the traditional ring box appearance.

To create the padded sections, I used some leather offcuts, rolled up with the suede side exposed. The front "pad" is literally just that.

The rear pad has rolled from a 'L'-shape piece of leather, like in the illustration. When rolled, this creates a small hollow in the tube, where the batteries will reside.

Electronics
The circuit is very simple. A white LED in the lid of the box will be powered by two G3A batteries (v. small cell batteries), and triggered by a normally closed reed switch. (i.e. putting the switch near a magnet breaks the connection).

The reed switch is carefully placed in the hinge near a small magnet (hidden under the leather), so that when the lid is closed, the magnet holds the reed switch open.


G3A is not a common type of battery, I just happened to have a lot that I recovered from some recycled electronics. As a result I couldn't find a battery holder for them, so I adapted this CR2032 design from Thingiverse.

The battery holder. View on Thingiverse.

The LED itself is just mounted with hot glue, angled down toward where the ring will be situated. The wires run down the inside of the lid to the hinge, where the reed switch is positioned.


On the base side of the hinge, is the small magnet which triggers the reed switch.

All of this is covered by another strip of leather, which is glued - suede side up, to the inside of the lid, and runs down to the hinge, overhanging it into the base (see photo). This overhang is tucked behind the leather roll containing the batteries, hiding all the wiring, but meaning it is still accessible should the need arise (to change the batteries, for example).

A moving shot to try and illustrate the sparkling of the ring under the LED light.

Between the sign and the cake stand, and now this, my projects seem to be very wedding-focused of late.

Originally this ring box was going to be a project for the same wedding as the other two, but unfortunately due to various circumstances, it didn't materialise in time for the big day.

So when my brother got engaged recently, I gave him the designs I'd already sketched up and he picked this one for me to build for him.

The woodworking component of this is pretty straightforward.

The wood I used is oak for the main body, and a darker hardwood (of the well-known species 'offcuttus miscellanei') for the sides, to provide a nice aesthetic contrast.

I was referencing an existing ring box for scale,
and purely by coincidence, the wood sections
I was using were a spot-on size.

Because of the small scale of the box, it's difficult to do any advanced joinery, so the pieces are simply glued, but the wood is light enough and small enough that the joints are still sufficiently strong.

Once all the glue-up is complete, it's off for some sanding to ensure everything's cleaned and squared up, leaving us with a sealed hollow cube.

Some work in progress shots of the ring box. This was certainly one of those projects that at times seemed a mess and you had to keep faith it'd look good when it's done. #diy #maker #woodworking #handmade #wedding #ring

With that done, the cube needs to be cut. Typically, it seems, most ring boxes are about 50-50 (half the height in the lid, half in the base). However, I've opted for a 25-75 split, leaving a larger base, as the plan is to include a small LED light, and I'll need space for batteries and wiring.

I took the hinge from the existing ring box I was using for reference. To fit it, I drilled out a small cavity in the back of the box for it. As the wood is only about a quarter inch thick, this was the most nerve-wracking part of the whole project.
Once I got it fitted, I sanded off the top of the base-back and the lid, so that their edges didn't collide when opening.

When satisfied with the opening mechanism, I epoxied the hinge in place.

Then the rest of the exterior is just a case of shaping with the sander and a coat of danish oil to finish.

Then onto the interior...
