Obi Conversion w/ custom heatsink

[xwingband]

These aren't the best pictures in the world, but enough to get you going. I'm not going to highlight the wiring it's the same as the Anakin and Vader. I used a Royal Blue K2 (positive from battery pack to let it suck the amperage it wants ).

To start:

The emitter unscrews. A strap wrench or something like a mouse pad to give grip will help you get it off. There is a pin in the threading, tap that out.

Pry under the edges of the gold activation box. Then unscrew the two shown screws.

Now the activation box will come off. You'll need to cut the switch wires off now. Push them inside the body.

Now the insides are ready to be pushed out... and I mean pushed! They have a sleeve in there that it's sole purpose is to make it hard to come out.

Punch the larger pin out all the way. The smaller one is really easy. It only goes in maybe 1/8", then flip it and get the other little pin on the backside.

Now it pops apart easily. You should see everything you need...

Now I removed the conical section of the guts to get access to the back. I dremeled the insides a bit to fit the custom heatsink. Then where the little pins were before I put 8-32 set screws to hold the heatsink. With the wires and screws it pretty danged solid.

I placed the optics in the upper sleeve. I used a bit of tape to space it. Now with everthing done with the Luxeon I rewelded it all with Weld-on 16. I even welded the upper sleeve which wasn't welded before.

From there it was a reversal. I slid it back in. Resoldered the switch and it was done!

The last thing was I tapped for a 10-32 1/2" socket head screw as my blade holding screw.

thank you! thank you! thank you!

i just got my obiwan this weekend and have been waiting for some pics.

thank you!!!!

[Ravage179]

just two short questions

1 - could you post a rough pic of how you wired the k2 to the battery
2 - is it any brighter than a 3 watt rb?

[xwingband]

It's simple...

I took the red wire from the three pins and snipped it. That is where I soldered the normal blue clash, purple and positive LED wire together. So that's five wires there...

Yes, I'd say it's brighter. Not "OMG" level of difference but it's noticable to me.

perfect, thanks!

hay X, what blade are you using?
looks kinda like the dual tube...

great work

[xwingband]

Nope, it's the stock MR. I can't really get any other blade in there right now. I didn't want to dremel the sleeve that thin. It looks much better with another blade, but the MR isn't too shabby.

Speaking of, I'm taking it easy before I come back here full-time. On my list as soon as Tim gets the new blade sizes is to make an improved dual-tube. The original one I have isn't too great construction wise.

Obi wan kits should be here this week and they use the heatsink2

[xwingband]

Cool!

I shouldn't have to do much to add it. I was just fiddling with it myself and figured a simple metal sleeve like the one for the 1.25" holder would work.

[Strydur]

Its close to that yes. But it has the notch in the side etc..
