Has something changed recently with the laws of physics/chemistry, where heat no longer softens/melts plastic??
Iāll put that on my list comfy. Do you think I should torch the top end? As a last resort Iāll bring it into the maintenance shop at work.
Burnāem outta there! Just kidding. Heat sounds good, or freezing it. Or Freezing it and then applying heat to the outside maybe.
Or sitting it under the drillpress and pressing it out?
I would probably attack it with one of these: http://www.dremel.com/en-us/Accessories/Pages/ProductDetail.aspx?pid=9901
Cut two slots front-to-back so you can break it into two pieces.
I just hit the plastic/nylon part with a mini torch. It started bubbling and burning like a tire. I have it sitting on the cement, itās still burning away all by itself. Like a tire fire. Iāll just let it burn and see what happens.
Things are starting to heat up now. 
It's still burning!
Itās still bubbling like a witches cauldron. Itās been at it for over ten minutes now.
I guess HID donāt need heat sinking, because even though the thing is on fire, the tube only feels warm.
Video or it didnāt happen!
Video would take too long to upload to youtube.
It's been twentyfive minutes, and it's still boiling away. I realized I forgot to take the o-rings off. Surprisingly, the tube is only warm and the o-Rings come off okay with no damage.
Still bubbling. I wonder how toxic this is.
After the fire died I poked and yanked out crusty things and components with a pliers. There seems to be an integral lip. I think the plasticy front plate was installed from the rear, and the epoxy poured in behind it. Iāve pretty well cleared it out now.
Now whatās left is the epoxy plug. It looks about an inch thick. Itās free and rattling back and forth. I started another small fire to clear the rest of the plastic (what is this stuff).
After the fire dies and I clean things up Iāll figure out how to get that loose plug of epoxy out.
Thanks comfy. Having a bonfire would have never occurred to me.
So is there a pressed in retaining ring behind where the epoxy was? What is keeping it retained so that it rattles around behind that lip at the front?
It's free and clear. Once the charred remains of the plastic and components were cleared, the epoxy plug came out the front. There are two low profile lips in the front that I assume retained the plastic. The epoxy must have bonded it there. There is another wider shelf at the bottom where the contact plate threads in.
A BLF first?
Nice job! :)
I'll make you a drill-press-pill if you give me dimensions (and it's under 2" OD).
Talk about PERSISTENCEā¦ but I guess a lot of us have ābeen thereā. Good job, ouchy!
Nice result! This gives me hope for all my unfinished stuff. :bigsmile:
Thanks comfy. Iāll have to check what kind of measurements this thing has. I also have to ponder on how Iām going to approach this thing. From here, itās all logistics.
Clear the trace right up next to the emitter, then cut the remaining trace so the pads are not connected. Wire it inside the hole in the reflector, in other words, the wires will show in the reflector. I did this with an SBT-70 in a HD2010.
The MT-G2 might work better in that HID reflector, remember that it's a lot of little dies, not a point source at all. Parabolic reflectors are very floody with the MT-G2 so this one might actually let it have a hot spot and some throw.
