CNCman's entry to the 8th annual BLF/O-L contest [ Handmade - FINISHED - ]

Nice work. :beer:

So here we have the body of the tail cap cut off. The battery tube measured .970 to 1.0 diameter, so PI x diameter = circumference + .1 per inch added for shrinkage. 3.1415 x .985 = 3.094 + .31 = 3.404 long x 1.5 wide.
Of course these are ball park figures used to rough it in shape.
It has to be pretty hot to mold by hand, you have to prepare and plan everything before beginning, the doing is trial and error. LOL

.

.
Just a tad too long, so it needed a trim, about .050 inch.

.
Some filing to finish.

.
It is necessary to make things longer and trim to length afterwards, the plastic gets distorted on the edges.
Of course rough and finish filing is always a must.

.
The small gap will not exist when finished.

.
Rough cut pieces for the switch and cap.

.

.
Dremel tools are priceless :heart_eyes:

.

.

.
Two clearance pockets were needed for the electrical connections.

.

.

.

.
No parts are perfectly round, so tiny notches were made to orientate everything and the finish filing was done to match.

.

.
Here it is, but not fastened together just yet. I had some trouble with the 2 x .4 mm tap, that fix tomorrow. :wink:

.

.

.

.
So far so good, I was concerned it would be impossible to make, but just one piece at a time is working. :beer:
.

Great work! I’m really enjoying seeing this come together.

:+1: :beer: What more can I say?

Great work

This is shaping up really nicely!
Looking forward to seeing all the pieces come together.

That’s awesome work—i love to see it come together. How is the gap gonna be eliminated? Guess that big-ass hacksaw got carried away with the plastic…

.
Screws and some glue. I may need access to fix something later so its getting some 2 x .4 mm screws.
The gap is a result of not being able to close it while molding it. It will be pulled together with screws. :wink:
.
The fun stuff is yet to do. Getting the head made is going to make or break this project. :slight_smile:
.

Coming along nicely

Great work. :+1:

Very interesting to see how the plastic can be formed. With a transparent flashlight, everyone can see how the internals of a flashlight work. You will need some batteries with a good looking cover.

This is looking epic

Coming along nicely! :+1:

Thanks everyone :smiley: It’s fun to be here with you guys. :beer:
To O’l Lumens and many BLF members who started this forum, THANK YOU !!

awesome work! I love projects like these.

Here we finish the tail cap complete and mate it to the battery tube.
The gap had to be closed to maintain correct fit. Using JB Weld and closing it in a vice for 24 hrs worked.




Gluing the switch to it’s mounting plate.

Cutting the spring shorter for the 3rd time.

Gluing the switch inside the body.

Hand drilling 4 x .041 diameter holes unequally spaced for 4 x .040 diameter x .25 long pins.
I was concerned the glue would fail under the spring pressure after batteries were installed.



Glued and pined in place.


Mating the tail cap to the battery tube.
Drilling 3 holes with .063 diameter drill for tapping with a 2mm x .4mm tap.





Finished :+1: Learning as you go is a result doing projects like this.
You can only plan a path, doing it requires flexibility.



.

Superb! :+1:

Very creative CNCman. I see a name change in your future if you keep using hand tools. :slight_smile:

Great work!

Ain’t that the truth :smiley:

Thanks guys :smiley: I started out a manual machinist many moons ago, so maybe the name is not accurate LOL.
Making the Head and the cooling is up next. I just found the right size Hot sauce bottle today for a mold, if it doesn’t break under the heat. :wink:

I do have a question about a “MTN 12mm Momentary Switch (for momentary / e.switch drivers)”

.
The driver i’m using to hook it to is,

.
I have and understand the instructions where the 2 wires go for controlling the driver.
I have the non-led switches in hand and just ordered some with led.
.
:question: My question is, can a lighted switch be hooked up to this driver ? It will need power, I do not know where or the voltage to hook the leds too.
.
This is for the build, so any help is awesome :smiley:

.
Here are the options for the driver below.

FET Driver - 20mm model FET20-SS

  • Zener Mod?: Yes - ~6V LVP
  • Firmware: Electronic Switch CU…
  • Turbo Timer: 120 Seconds

Electronic Switch CUSTOM Firmware Options.

1. Number of light levels: 4

2. Approximate PWM levels of each mode: (1) 10% - (2) 30% - (3) 60% - (4) - 100%

Zener Mod: Yes - ~6V LVP
