Are you saying that the lenses are too big in diameter to fit in the bezel? That's a shame - evidently the latest batch are bigger than the ones I got. Mine just dropped straight in.

Anyway, no matter. The torch is 1000 times more useful with the stock lens.

How good is the throw with the stock lens?

Dioni · #63 10-07-2009, 09:10 PM

Can someone post A pic? please!!!

iflyjts · #64 10-07-2009, 09:12 PM

That's It EXACTLY! I'll try to work it out, but as U say, The Torch is a BRIGHT light! and the pricing is right...

Thanks for your help!

I saw it. I mean some beamshots with aspherical lenses

Beamshots? Please, anybody?

iflyjts · #69 10-13-2009, 06:06 AM

Anybody got their B3 up and running with the !MR13 yet? Im interested in the runtimes if you do. With the EO13, this is one of the brightest lights I have (as compared to Mag11, Mag85)

Sorry no Beamshots

Still can't work getting the aspheric lense in the bezel...
Anyway, a lot of BANG for the BUCK in this light with the EO13 setup. Thanks for the recipe Bruce!

I think the runtime on 3xIMR16340 will be around ~10 minutes as the chart on the LF's site.

Just a thought on lenses. As the topic name implies, they will only serve to put the fire. Long distances I don't believe these lenses will focus. Perhaps without the reflector it would 'cause because in sotck B3 that can be done, however the IMR-13 is uncompounded.

Am I correct?

Am I correct?

Yes, close enough.

The aspheric lens I specified, from the-dealer-we-dare-not-name, has a longer focal length than the distance from the filament to the back of the lens, and we cannot change that. We can't make it focus; there just isn't room. I think the EO-13 is a little better match in that respect, but the IMR-13 has more output, so it's swings-and roundabouts. And swapping for the B2 tube allows you to try the IMR-9L in the smaller form factor.

Either way, if you hold the torch at the focal length from a piece of paper, you will set it on fire.

But all this is academic. The stock B3 glass lens is far more useful for all 3 bulbs, and member iflyjts has reported that recent production aspherics don't fit the bezel anyway. I was just lucky, as my lenses are 43mm OD and thus undersize. Evidently, more recent production is up to the correct advertised 44mm size and won't fit. Be warned, or perhaps find an alternative at Surplus Shed or elsewhere.

Still, it's a fun project.

Dioni · #73 10-26-2009, 05:47 AM

I see it is more than a fun project, after all it's the cheaper way to use D36 drop-ins.

Thanks!

Well I finally got all my parts in from China.

The Aspheric Lens was too large, so I used a bench grinder to make the lenses fit in the head. Use safety precautions!

I fired the B3 up with 2 17500 and put an aspheric lens in. Using the stock bulb at 7.2v I could smolder newspaper but no flame, impressive amount of smoke.

Took out the parts as listed by Ictorana in post 1 (after I insta-flashed the stock bulb it didn't like 3 IMR16340)

Took the outer spring off the IMR-13 and set it in against the body, good contact.

Uh Oh it doesn't look like a good fit the head is not even all the way on the body, see the second o-ring?

Put the bezel on with aspheric and couldn't thread on at all
As far as I can tell the B3 is the same as in Ictorana's pictures must be the LF Lamp Assembly

The IMR-13 is too long to fit but I have a plan to extend the head and grind some material off the IMR-13

The head is in two pieces and needs a grippy wrench and maybe a torch to break the threadlock. If I extend this and grind the outer spring groove off the IMR-13 I think I will have enough room to get the head closed. I may need to grind 1 rib off the reflector of the IMR-13

So tomorrow I will do some extra fitting to see what this B3 Version is capable of but looks like Ictorana's version is better since it all just drops in.

lctorana · #75 11-03-2009, 02:49 AM

Yes, you do have to remove the O-ring in front of the glass.

Dioni · #76 11-03-2009, 02:21 PM

Thanks for pics nein166!

nein166 · #77 11-03-2009, 11:42 PM

Got it together and BURNING!
I'll try and get a video tomorrow

By the way wear sunglasses while burning!
The reflection is too bright

Oh and if you use a torch on the light it turns a real nice copper.
While heating the glue so I could make room in the head it turned this burnt sunset color. I was using an acetylene turbo tank, HOT.

Just wondering if this works with most TypeII and TypeIII anodize?
Because I really love this color.

lctorana · #78 11-04-2009, 03:30 AM

Very pretty.

ANDREAS FERRARI · #79 11-04-2009, 04:12 AM

nein166-are you a professional photographer???Because those are some of the most beautiful and clear shots I have seen on CPF!!!!! I can't wait until I see some beamshots!!!!

I was going to post a few shots of my own in another thread,but after seeing yours-

Thanks but no I'm no Pro. My Dad is and he helped me choose a great point-and-shoot camera.
I don't think I inherited any of his skills. A Tripod is a must.

White wall at 1 meter any one, HA HA HA thats the ugliest thing you'll see.
Burn shots at 1 inch is too bright to look at without shades.

So you are saying that that orange color was simply from heating the light with an acetylene torch? That is really strange. I have never heard of anything like that happen before... It seems like a very uniform color. Did you heat up the whole body with the torch?
Since the light was dyed black, there should be no orange dye present. The dye is also sealed into pores in the anodizing, so unless the anodizing is being un-sealed, then the dye shouldn't have much to do with any color change.
Does the color seem permanent? THe only thing that I can think of is some chemical reaction, but I'm not sure what elements present would react with aluminum oxide to create an orange color.
Am I missing something here?

nein166 · #82 11-04-2009, 10:30 PM

Mjolnir and everyone else I started a thread on the color change over here
So this thread can stay on topic which is burning paper not anodize

bigchelis · #83 11-04-2009, 10:53 PM

This is a super inexpensive hosts for a D36 drop-in...

Assuming you don't want to use the aspherical lens, has anyone got the theirs to simply accept the D36 Lumens Factory drop-in with no grinding needed?

Thank you for this great DIY firestarter build. Now it gives me an excuse to get the D36 Nailbender drop-ins too.

Yes, mine dropped straight in. That was my original point of starting this thread.

Do you mean the head has screw on screw and then it could be extended? Did you do it?

Yes it can be extended. If you take the head off the body and the bezel off the head you are left with a bell section and a ribbed section that are threaded and threadlocked together. The threadlock breaks after heating but if you heat it too much you wind up with an orange flashlight.

Beamshot!

!!!BURN Link!!!

Dioni · #88 11-06-2009, 04:22 AM

That was I thought about the beamshot with aspherical and reflector. The lens reflected the OP finish in the wall.

Thanks for pic and vids!

jahxman · #89 11-09-2009, 01:08 PM

nein166, thanks for bringing yours to PF13 and lighting things up with it! It was fun to see this in person, I'm very tempted to try and build one, even if I do have to try to grind down the aspheric lens. Unless I can find some 43mm ones somewhere.
