More work on the wood today, this is quite difficult when all you have is metal working tools. Hats off to you cabinet makers out there Thumbs Up

I marked out the rectangle shape to be removed with digital calipers fixed to 8.5mm for the long sides and 10mm for the top & bottoms as these still have work to be done on them. I drilled a series of holes inside the lines then used the drill bit(s) to go around connecting the 3mm holes. Snapped five bits doing this Tired

I tidied the holes up with a file, might sand down further later.

You have to love a good looking piece of wood. How big is the vice?

That one has 4” jaws and a maximum 4” opening, I have two small tabletop vices that I use, not fixed down to anything so that can be fun sometimes Smile

It’s even harder working metal when all you have are wood working tools. Wink

I like that wood. Looking nice.

That vice (with the orange button) looks like a twin to one of mine.

I can totally understand that Big Smile
I thought about the wood for a while going between american walnut, ebony, rosewood and a couple of others but being honest I chose this piece because it was the closest cut to the dimensions I required Wink
Yeah an ex got that vice for me at lidl about 7 years ago, best thing she ever bought me Smile

Thanks CRX. The reason I asked how big the vice was is to get an idea on how big your parts were.

More work on the rosewood, drilled 3mm holes for the red bottom LED's, charging indicator & top momentary switches and cut out a channel for the USB charging port with a junior hacksaw.

Had an idea to cover the back end of the auxiliary LED's with a mix of glow powder and resin.

The USB port I have taken from an old converter that I had.

Sanded down two momentary switches.

Marked out and drilled holes for wiring in the mid copper layer.

Bits n' pieces.

The project is coming along quite nicely.

I love watching this rapid prototyping take place.

Some great out of the “box” thinking.

Sorry I had to say that.

Anybody else still confused about what this is supposed to turn out like? I looked at the renders in the OP, and all these progress pics, and it still eludes me. I see it has a quad? And then the 5mm AUX LEDS go on the “bottom” along with a charging port?

All will be revealed Wink
Yeah, quad main light, some UV emitters around that and red LED’s on the bottom.
Two momentary switches, one for the quad driver, one for UV resistor driven and a mercury tilt switch for red LED’s on the bottom. Rechargeable via micro USB port, built in TP4056 or TP5000 charger board.
Are you saying my drawings are crap? Big Smile

Got the copper layers & wood marked up and drilled for the brass fixing screws today, very hard to get these lined up straight without using a drill press but I did ok.

Copper layers.

Copper & wood layers lined up.

I used a scrap piece of copper to test and show how I will be installing the slotted M2 screws into the front and back plates.

I think I will practice some more before working on the finals Big Smile

Reference drawing

Something else I have thought about is etching the copper with my username as shown in the mock up drawings, I did a small test on the scrap copper with some ferric chloride.

I cut out a disc of tape and applied then used correction fluid to mask, left to dry then removed the tape. I dabbed on some ferric chloride and left for an hour then brushed up the copper, just to see the effect. It leaves a shallow etch in the copper.

So battery one side and the rest on the other side?
RBD helped me a lot understanding things. He is on less and less these days.

I was just wondering how he was doing the other day.

Yeah, will have the lipo battery, one tritium momentary switch, a mercury tilt switch, the USB socket and two red LED's in the bottom section along with a copper heatsink bridging the mid to lower copper plates.

The top section will have the quad board, 10621 optic surrounded by maybe 8 UV LED's, 34mm glass on top, the driver, charger board & external indicator, one momentary switch, maybe one mercury switch and two red LED's.

So going from left to right = bottom to top layers sequence

Looking something like this when finished, about 84mm x 53mm x 20mm

Today I got the brass pillars made up which will hold the front & back cover plates in place.

These are made from sixteen 5mm M2 brass standoffs which I soldered together Tired 

Shown in the first picture is the back copper layer with the standoffs screwed in prepared for bonding the two bits of wood and copper mid layer together.

The second picture shows the copper heatsink bridge which connects the mid layer to the bottom for a thermal pathway.

The third picture shows the two rosewood pieces bonded to the copper mid layer with toothpicks in the screw holes to keep them clean.

Ready for filing into shape I used tightly wrapped tape for support to the temporary alignment screws so less pressure would be on them.

Roughly filed into shape, looking square on all sides Thumbs Up 

 

This gives you an indication of the size of the unit

Time to drill out the front hole for the quad emitters.

I used progressively larger drill bits then a rounded file to get most of the material out, still needs neatened up some but this is where the circles I scribed earlier were very useful.

Thanks mate, that wasn’t through choice and only half the story with the standoffs, I couldn’t find any longer versions that were thin enough.
I had originally planned to use thicker ones but soon realized the wood would not tolerate any larger sized holes through it given the close positions to the edges, real headache there, about two hours soldering these things together straight, building it up only to have them snap off at different places one at a time when I tightened up the faceplate screws LOL

So I had to then redo the whole lot with threaded 2.5mm2 solid copper wire soldered through inside.
Don’t ask how you thread 2.5mm copper wire Big Smile

Looking good CRX. You are gong to have to get a thicker wallet to hold this credit card sized light.
I must of missed the bit about threading 2.5mm copper. How did you do it? Silly
