I’m planning to enter with a mod, just have to decide which one.
There would be a SP70 mod (3 or 4 XHP70.2) or a build with eight quad Carclo optics that I’m about to start in the new year.
I like the contest but the problem is that machine made is only for people with a lathe and the hand made category allows no parts like battery tubes.
I’m not skilled enough to build a flashlight without a threaded battery tube.

Agreed, I do not have a way to make threads that are good. I started a light that was going to be a large gauge copper wire battery tube and all parts were going to be silver soldered together including the wire wrap tube. But, I did not and do not have a good enough oxy torch to solder it all up… I may try again, as I have the torch and hoses, but do not have the gas cylinders and they are just to expensive to lease in the US for a hobby.

I would think a pre-threaded pipe would be allowed.

Yes absolutely. Didn’t DBSAR make a light using assorted pipe nipples and fittings a few years ago… contest 2 or 3 I think?

Another wee torch for you today
I built this copper & aluminium triple mule flashlight out of some 3/4” plumbers pipe, 1” aluminium tube and some other bits ’n pieces I had with the usual hacksaw and hand files.
It has an S6 brass pill filed down and soldered into the copper tube along with a filed down brass retaining ring holding the reverse clicky switch.
I’ve used a slightly different design with this light, incorporating a sliding inner core held in place by friction and …
Well I suppose I should make a start on this years, The 2018 Annual BLF/ Old Lumens Scratch Made Light Contest entry.
I am feeling the pain already from all the filing & sanding to be done, though I like it really... [image]

I received some parts from a giveaway by leroycp a few days ago and as I stated in that thread, I have made a light and dedicated it to Old Lumens.
I have used brass tubing, copper bar, hand tools and used a couple of his methods to make it, most notably the tail switch locking piece. He did seem to like my work with brass so I would hope this light might be to his liking too.

Hello and welcome to my build thread for the 2017 5th Annual BLF / Old Lumens Scratch Made Light Contest which is a competition where BLF members take part by making a flashlight or set thereof from scratch and was started by now deceased member Old Lumens who loved modding and making flashlights.
There are two categories, Machine made and Hand made.
Again I will be entering the hand made category and making the light(s) using only small hand held tools.
This years flashlight will be made fro…

I decided to make a lighted switch on my SGN3.
Opening the light up did not go exactly to plan :FACEPALM:
I may have become slightly annoyed with it during the process O:)
So how am I going to fix this...[image] Well, I have had an old piece of one inch aluminium box tube shower rail sitting around for years in the cupboard and had an idea so I got to work making a new case with that
There are five 10mm neo magnets epoxied inside the shell on the front & back and one in the tail. …

This one is powered by two 120mAh parallel lipo cells, has a side reverse clicky switch with a 1206 white SMD LED locator light in line with a 4000K resistor and a micro 200mAh USB charger unit with white LED charging indicator in the tail.

The outer copper casing is 12mm plumber…

Well, hell.
I happen to be in direct contact with Mr. Old Lumens himself and his opinion is excuses are like a55holes, everybody has one. Just do what your time allows and show it off. Wrong time of the year? Too busy? It is what it is so just do it!
Forget prizes, forget pride or perfection… the real reward is in accomplishment. Getting involved and creating with your own two hands. Doesn’t have to be epic, doesn’t have to rewrite the origins book, just get involved.
Make Justin proud and rebuild a Maglite…

Thanks for the handy links of awesome examples, CRX. They’ll surely come in handy.
Dale, you must either have some really supernatural connections or some really good pain meds… or both! I kid, but I fully agree with your statement. Don’t look at what others have done and feel that you’re not worthy. This contest is for fun, inspiration, and keeping the spirit of Justin alive and well around here!

I’m in a rather unique position in this as I not only have the lathe from Justin but also the majority of his gear, from two drill presses and a band saw to belt sanders and the dip sink he used to put flames on a Maglight… even his Mag parts and all the bits and pieces he modded with. I’m surrounded by Justin in all that I do concerning flashlights.

AND somebody put me up to using some carbon fiber tubes AND someone else gifted me some Timascus and Mokume Gane bar stock… it must be time to figure something out.
Now where do I get my hands on a Luminus 90.2?
Edit: What? Just because I’m thinking pretty and small doesn’t mean it has to be puny!

We prefer the terms Tinkerbell or Monster
For me it has always been a time thing. I was able to chime in the first few years, but the last few I just couldn’t do it. That said I do hope very much this tradition continues. I do sort of wonder if running this during the summer months might be better for some vs the holidays/tax season etc… For me time of year is not really the problem though.

I voted for: “I plan to enter but haven’t got around to it”.
I have some decent idea’s that are perfect for a competition like this.
Unfortunately I still have a lot to figure out en test before it can be build.
Also the majority would need to be 3d printed and I still have to finetune my printer.
Last 2 years I just didn’t had the time, luckily I have more free time from now on but still need to prioritize some other stuff first.

I don’t know if i could finish it or not. Still thinking which category to enter…

Personally yes, that’s a great idea. This is the time of year I have the least hobby money and the least free time.
This is flashlight using season, spring & summer is flashlight building season!

It’s always the wrong time for someone… Would it be “too much” to allow all builds from Jan 1st to Dec 31th?
