The 6th Annual BLF / Old Lumens Scratch Made Light Contest

At the very least I have to post in here, right? So, perhaps I will make an attempt to find my brain and see if there’s still something rattling around in there by way of ideas for an entry…

… I’ll be back.

You have shown us all here that you have more than rattles in your brain Dale. Your one of the wiz’s with all things flashlights here? :+1: :beer:

Thank you Steve, but the past year has been difficult and the past month has been brutal. Rattles may soon well be all I have left…

That sounds bad. I hope everything works out okay for you. :cry:

Justin used to say… it is what it is, y’all know I ain’t got sense enough to leave modding alone, regardless of how I feel. :stuck_out_tongue:

Lanterns are popular this year, first three entries….

Well, if it makes you feel any better, I WON’T be building a lantern. :wink:

I’m thinking of making a thrower, using the 200mm condenser lens from Edmund Optics, maybe with the focusing aspheric I removed from a Canon ultra wide angle lens. Just have to figure out if I can make the 4-jaw chuck work on the lathe and what materials I need to get as compared to what I have on hand. Haven’t decided on emitter, thinking about the SBT-70 for it’s round die. That would, of course, reduce throw considerably but would give a fantastic pattern and possibly 2000 lumens from a 3V emitter. I can’t see much over a mile anyway…

Sounds amazing Dale. I hope I have internet access OS. :+1:

hope we see some realy nice builds again this year.
unsure at this stage if I will enter anything.
all the best to all

And another BUMP. :slight_smile:

Too many things going bump in the night around here! Dang near shot my monitor! :stuck_out_tongue:

Oh, and uh, a friend gave me some bits and pieces, absolutely gorgeous bits and pieces, that may have me going a different direction in this build. :wink:

See what my friend gave me….

Mokume Gane and Titanium Damascus, both about 30mm x 40 mm. So, a new challenge is born… what to make with these 2 gorgeous pieces of exotic bar stock?

Oh wow! :heart_eyes:

Well, those are pretty… What can you make out of two 30mm x 40mm pieces? They’re a bit short and wide for most flashlight shapes.

Could be a set of ten keychain-sized 10180 lights, or maybe combined for a 26350 thrower, or maybe split up for three 14500 lights.

Could make the Timascus into a head and tail, and the Mokume-gane the mid-section, adding a portion of pure copper for the pill. Quad-bore the Mokume-gane for 4x14500 in series and make the light a triple or quad XHP-35 mini-powerhouse!

Or just a 30000 lumens camping lantern …

:smiley: That would be something Dale’s style :sunglasses:
Those are some pretty nice pieces! I don’t know what you’ll do, but I’m sure it will be classy!

Good luck! Looking forward to see your thread as well :+1:

Y’all are killin me! :laughing:

Y’all’s math is horrible though. Side by side 14500’s take up almost 30mm of space, these are only 29.8mm wide. 4x 14500 would need a much fatter piece. Nice try though. But of course the 40mm length also isn’t compatible with 50mm long cells. Oh well.

BUT, David is onto something, which I’ve already been laying out. A Quad with a copper engine, 16340 cell powering an LED4Power 4A driver in constant current, with the copper/brass as the body and caps of the Titanium damascus top and bottom. :wink: I REALLY want it to be a side switch, that would solve some space problems, but don’t know if I can pull that off and sure don’t want to mess up this gorgeous piece of Mokume Gane trying… probably heat color the Titanium a rich blue to oppose the orange of the copper. Should be interesting…

Doesn’t have to be mega powerful, the 80 CRI Samsung LH351D’s at 5000K should suffice to make a nice beam profile and decent color, but I’ll look into that aspect more later as TK is telling me the Carclo optics don’t play all that nicely with her Samsungs.

Jewelry grade light, haven’t done that before! lol

(Hmmmm, 4x10440…… )
