G0OSE's Old Lumens Competition 2020 entry

Ok, so bit of a late entry and I’m still waiting for 1 part (glass ar coated)
I will upload all the photo and write up when I’m finished.

Well I haven’t a lot of spare money so I decided to do a small light utilising a $3 broken pen light which to be fair is quite powerful, just badly made. This will be a real budget build.
It is going to be brass, 1 mode, 1aaa (maybe 2) Nichia 219BT Neutral White 5000K CRI80, there will be some glow bits and maybe some patina work.

Here is a sneak peek of the switch…. not finished yet.

Ok, so this is the first time I've entered this and it was a bit daunting. However, I am very pleased with what I ended up with, although it's not finished.

This year, like many of us money is tight, so I decided rather than buy more, I'd utilise one of the pen lights I'd bought and given away as presents. they are really powerful, but sadly have no pill, in fact noting, the led board sits on a ring, as such it did not cool well, in fact it barely did anything. In the end the led popped in mine so it was dead - I decided rather than buy a new driver, reflector and switch I'd re-use the ones I had.

I already had some brass tube, so all I needed to get was  an led, I could have re-used the lens but it was plastic so I bought a double AR coated one from Kaidomain with the other bits. I also needed a few gas plumbing bits with threads as sadly I can't do them and my old lathe doesn't have a particularly good feed, it was kinda botched on from another lathe by the previous owner and it's 1 speed lol.

The gas plumbing bits would provide the threads, which I will steal from them as you'll see later.

I will just say I intended this to be hand made, and at first I was managing with a step drill in my regular B&D drill, but the holes I was drilling were so close I just couldn't drill straight enough every time and lost parts going off-centre and cutting the thread i was trying to steal. So I had to do parts on the lathe. I could have done a lot more by hand (like polishing - could have used drill etc) but since I'd already moved into machine made now, I thought I may as well use the lathe more making my job easier....slightly.

I will just say NONE of this was really planned, or written down - I kinda had the idea in my head and just did it on the fly, jumping hurdles when i needed to!

 The donor light - they are not bad stock, but they will burn out eventually due to no cooling whatsoever. They are very powerful though with a good tight beam.

 Ok so here we have some pics of the brass barrel lock innards, I get these from my work when they break - little springs sit in those hole with the pins on top of them etc I started filling slices of them with gitd a while ago and they are useful too for bits. next you can see the newly attached Nichia 218BT 5000k CRI80 from KD. I quite like this colour, I have been liking sst20's in 4k but they are rather warm for some.

 

 

Pill V1!!

20201126-131123 20201126-132219 20201126-132232 20201126-132240 20201126-132250 20201126-133705 20201126-141524 20201126-141810 20201126-141816 20201126-150753 20201126-153220 20201126-153922 20201128-183447 20201128-183455 20201128-184452 20201128-190721 20201130-195849

 Here we have my first attempt at the pill. Those brass barrel locks as it happens are the exact size of the bore of the brass tube I already had, which was very lucky! This first one was made entirely by hand, no lathe involved. Soldered a copper piece on the end, shaped it with a file the wet and dry paper.

Sawed off the brass barrel (no holes in the bottom end) the step drilled it out to 12mm for the driver to fit. later it became apparent this pill was going to be too long..... this is what happens when you don't draw it first lol! but hey, it's part of the challenge!

 

 

The switch.

20201202-184736 20201202-194108 20201202-195833 20201202-195912 20201202-200917 20201202-201116 20201202-211839 20201202-211922 20201202-212031 20201202-212041 20201202-214356 20201202-214411 20201203-095112 20201203-095129 20201203-095142 20201205-201531 20201205-201536 20201205-202305 20201205-202523

 The switch is the part I was looking forward to the most making. I knew in my head what it was going to look like so it was easy to make. I already had the switch and luckily it fitted perfectly into the brass gas fitting I was using, like a glove. Sadly the switch was to cause me some hassle later, it was just too long really - if I was doing it again I'd get some other shorter switch unit. I constructed the inside with another of the brass 1/4" caps. Firstly I flattened it off with my parting tool, then I drilled it out to fit a little brass cap I'd found on another switch (theres a photo in a section further down) I drilled the cap out but not right through so the little cap would stay in, put a slice of pipe around it and a slice of the barrel lock with holes. Next i filled the holes with gitd powder and UV resin mixed. Lastly the whole thing was soldered together with 'Engineer' solder paste - where has this stuff been all my life!!!!!????

 

 

 

 

The Head.

20201205-225007 20201205-225016 20201205-225041 20201205-225044 20201205-225121 20201205-225227 20201205-232347 20201205-232354 20201205-232400 20201205-232409 20201205-234528 20201205-234535

 Here I am making the head, using 1.5 1/4" female sockets, turned down diameter to the 16mm same as my pipe and soldered together, then it needed to be drilled out to enable the pill to fit in (13mm). I had to leave about 5mm of the 1/4" thread at the bottom to enable the body to screw into it - the pill is loose inside eventually (not sloppy loose) and when you screw the body on the batteries will push through up into the spring and keep it all tight.

 

 

Switch porn...

 I really was happy the way the switch came out, so did some glamour shots lol!

 

 

 

 

Joints....not the smoking kind.

20201206-112055 20201206-130411 20201206-130803 20201206-130810 20201206-131603 20201206-132659 20201206-132730 20201206-132934 20201206-140244 20201206-141820 20201206-141826 20201206-141859

 Here we have one of the trickiest parts of the whole build. this is how I stole threads from the fittings to use in the pipe. Firstly the male threads, I drilled the nipples out to 10.5mm to enable the batteries to fit through, then turned the hex out. Then female threads turned down a female 1/4" socket to 14mm (the inside of the brass pipe) then parted off on the lathe. I will use these bits to put the joints in the light.

 

 

 

The back of the head.

20201206-142939 20201206-142944 20201206-143448 20201206-143722 20201206-143830 20201206-143940 20201206-144243 20201206-144323 20201206-144550

 This is the back part of my head, using another 1/4" cap. Turned the cap to 14mm to match my tube id and left the thread, this will screw into the body. I hold it in the lathe using another 1/4" female socket.

The head is made from 1.5 of the female sockets, soldered together then turned down to size. Once this was complete I had a rough  idea of lengths and it was obvious the pill was too long - I ended up making 3 in the end! I will use the others in next project though so not wasted.

Pill v3....

20201206-222808 20201206-223058 20201206-223144 20201206-224505 20201206-224949 20201206-230421 20201207-201035 20201207-201124 20201207-201204 20201207-201622 20201207-201712 20201207-201727 20201207-202035

 Here is the pill v3 which is so cute.......... made the same way as it's longer brothers but fitted lol! The shots below show me drilling out the head, which maybe should have gone further up this write up, but hey ho...

You can se the cutey pill fits right in now and the spring sticks out the bottom, held in bu the little bit of original thread I'd left when drilling out.

 I am internal turning out the slot for the glass lens here and below cutting the body /head thread joint to length - took a few go's to get it a perfect fit.

20201209-142225 20201209-142232 20201209-153957

 Here I am making the retaining ring that will hold the glass, and indeed the whole pill assembly in. I started with a 1/4" Brass Hex cap with a lip which was bigger than the body. I firstly used the parting off tool to cut the washer out, then drilled it out to 10mm with the step drill. Next I parted off the ring which was tricky as there was only just enough room for the parting tool as there wasn't much 1/4" thread to grip.

The ring was then sanded on wet and dry, varying grades, then I decided I would superglue this last piece on, for several reasons, the main one being I was worried about melting the reflector with the heat, which sadly is plastic and I only have 1.

Nearing the end and some beam shots. Here we have it all assembled and working - then eventually polished right up. This thing is damn powerful for what it is, really. The beam went all the way to the bottom of my rather scruffy garden and lit my entire kitchen!

In photo 7 check out the weird ar reflection/hologram! and in photo 11 on the floor it is glowing blue - look like a firework! weird.

Now for those who liked it shiney, it’s about to get very un shiney very fast…


After watching some videos on youtube for jewellery patinas, I came across this robot voiced, but very thorough set of video tests, there are several more but this one is definitely worth a watch.


 


 


So I am using ammonia, white vinegar, soy sauce and salt.


First i found a suitable tall container with airtight bag and elastic band, scrunched up some kitchen paper in the bottom and liberally sprayed with ammonia and also put a little pot of it in the bottom. Next made a little hanging bar with some copper wire, then cleaned the glimmering light with isopropyl. Next with gloves and glasses on I cover the light with vinegar and push lots of pink Himalayan salt on thensealed on the bag. Within just 10 minutes things started to happen.


20201210-105432 20201210-105633 20201210-105823 20201210-110243


 Next I used soy sauce and more salt, because according to the video it does a nice green colour, whilst the vinegar gives darker blues though it all changes when dry anyway. left about another hour.


20201210-110335 20201210-111507 20201210-111808 20201210-114302 20201210-114430


 So I keep popping down the shed every 45 mins or so gently re applying in sequence and randomly dotting, vinegar and salt, then soy and salt. re sealed the airtight container and left again.


20201210-114951 20201210-115120 20201210-121619


 Now we are starting to get somewhere, about 4 hours of playing. this is starting to look beautiful, copper and gold. But i still want more blue so it’s being left again.


20201210-143224


 More photo’s to come, this is not finished yet!


Soooo……


It’s still not quite finished but here’s where we are this morning.


3 coats of lacquer, but I’m not happy with the surface – I left a couple of bits of salt in it.


I’m gonna 1200 grit it down then re apply lacquer and then it’ll be done – until then here’s what it looks like today!


I don’t wanna blow my own horn – but sometimes you have to lol (I deserve it, it took a LOT of time and effort to get that patina lol)  – but it looks AMAZING!


I’ll take some better photo’s for the end part .

 


20201211-092256 20201211-092137 20201211-092144 20201211-092156 20201211-092150 20201211-092214 20201211-092211

Well it’s all finished now… 10 layers of lacquer and rubbing down in between every 2 layers and it’s just about right I think. Funny, it appears a rough surface, but in fact is ultra smooth lol.
Don’t forget to click on all the photo’s to see full size, and to get max resolution you have to click the ‘load full resolution’ or is will appear blurry.

Thank you guys Thumbs Up Did quite a bit more last night (and a bit more lathe work). The tailcap is all soldered together now, I stole one of the threads from a nipple after drilling out and inserted it into my brass tube, soldered it in and now we have a tailcap and a body……. which screw together lol!
As soon as that glass lens comes I can start the front head assembly. Worst case scenario I have a plastic one which I’d rather not use. I also have an optic which may fit…
Made a 2nd pill slightly shorter than the other last night too.
I am tempted to make 2 heads and maybe split the body to allow 1 or 2 cell use, it will mean more careful nipple drilling Facepalm there is literally next to no wall thickness left after drilling those 1/4” nipples to 10.5mm, one tiny move off centre and you lose the bottom of some thread.

Thanks pp! I might just go and ruin it now in the ammonia tank Evil worst case scenario I rub it all off and repolish.
Those cheap ass lights really pack a punch for $2.50! It surprised me how powerful it is for a 2x aaa.

It’s not quite done yet, this is just where I am at the moment. Just to be clear- the one below isn’t mine lol, it’s what I’m trying to do.
I have some off cuts of bras in an ammonia tank with salt on sealed up overnight to see how it pans out.
I’m gonna o a few tests before I jump on the main event and do the main light. I am going for something like this maybe… and I may put some glow elements on before lacquering if I go that route.

Well been having some patina fun today, still not done, check out the progress so far Here above
It is still not finished yet but looking pretty sweet so far. Thumbs Up The copper is pulling ot the brass really well, more blue needed though. I think I will end it late tonight and just let it dry somewhere warm. Tomorrow I can lacquer it as it will need sealing.

Shocked Oh my Shocked G0OSE Big Smile You have been very busy ! I’m still looking thru your pictures and this is a very well planned build. The tail cap lights are beautiful and the lathe machining came out very nice. Small parts are harder to make, Good Job !! Thumbs Up The finish is a surprise I was not expecting, but you pulled off a Great Finish. We are looking forward to see it completed Beer
