Found! Obi-Wan Kenobi ANH Lightsaber Emitter

[obee1]

here is an offer......if in some way i end up with one of these emitters......


i will offer replicas at COST to anyone here who wants one.. I do not want to make any money on this. Serafino and i have been working on making this thing right for a long time. Our last steel emitter was really good. I would just like to have them made perfect now..

 

[Gigatron]

This just keeps getting more and more exciting .

Unfortunately, I still haven't heard back from that NOS supplier I had contacted. Maybe if we get an actual part number, it would be more helpful to them.

Put me on the top of the list if there is going to be one soon

Don't know about you all, but I'd feel like a schmuck if I had a part of an engine taht could have been used to keep that sucker flying for a few more years.

I don't want to downplay your concerns, but if the parts were that rare, and really in demand, then the plane people could just machine one of the parts for themselves.

I'm sure this happens all the time with parts that can no longer be found.

If that happened we could get an even better machined part made from people in the avionics industry.

Plus if this engine has been sitting there for years and we found it, don't you think that the plane people would also know about this place to?

I also don't think that the interconnect would ever even break. This thing was made at a time when things were built with pride, built to last and with quality craftsmanship.

No bloody bevel. :lol

Since the ring IS a separate part after all my argument to the contrary, I should not be surprised... :rolleyes

Hurry up Chris, this is too cool. ...and way to go again.

 

[Aeon]

I've been reading and following this thread for some time now and I must say I'm VERY excited to see this emitter search put to rest. I would love to get a replica if the price is right.

Like Serafino said... HURRY UP AND SHOW US...

 

[Serafino]

Ok I'm back, are we there yet? :love

 

[kurtyboy]

Do we know which model(s) of Derwent have the correct inter-connector AND IG88 head yet? And how many correct emitters there are per inter-connector? :confused

[gavidoc]

Bevel? What bevel are you guys talking about? Who said the ring of holes wasn't a seperate part?

 

[Serafino]

The ring of holes looks beveled in screen caps from the new DVDs.

No seam is visible between the ring of holes and the flange, so I always argued against assumptions that the two were separate.

 

[kurtyboy]

Its a Mk 8 thats in that scrap yard. My questions have been passed to one of the directors (who's away at the moment) and I'm waiting for him to get back to me. I'm trying to negotiate a deal with them or find out if we can buy parts only, or sell back what we don't need.

So Chris, please try to verify if the Mk 8 has the correct IG88 and emitter/interconnectors.

The Mk seems to be the most common one so I'm hoping.

 

[OldKen]

always been one of my very favorite sabers, looks like im gonna finnally be like every one else here and break down and build one.

this is the most intrueging thread on the board.

any idea what cost might be in reproducin this thing?

im guessing not yet, but someone please let me know.

keep up the good work.

we need to start calling this emmiter the holy grail or something... cause if you guys were looking for the cup of ******, youd probably find it. :lol

 

[Serafino]

Marcus,

I think there's money enough to cover the price of that thing. I wouldn't worry too much about reselling the remaining parts.

If I get an emitter for $3-500 and we donate the rest to people who helped us I'll be VERY happy.

I'm sure IG88 people would say the same to getting a real one for $700 or whatever.

i will have no idea until i get one of these in my hands or a complete set of detailed specs. cost will depend somewhat on how we do it. i would love to look at casting this in metal if i get one... So it would be an EXACT replica..

yeah having an exact replica of the emmiter would rule, i cant wait to see these things... :thumbsup good stuff.

 

[amish]

I think I am going to freaking faint. Chris, nice work on scoring a good contact for information and possible parts.....

Everyone else who has had a hand in this discovery, I owe you each a debt of gratitude. While I have no need for the actual found part, I anxiously await the day that we can have 100% authentic replicas

So thanks to each and everyone of you, you made this Star Wars fan's dream come true...

Keep in mind that the interconnector is most likely an assembly of 2-3 parts that fit together, as I've previously modeled it here:

http://www.therpf.com/index.php?...pic=96585&st=74

In fact, based on my interpretation of the cutaway diagram, there's also some sort of solid or cured sealant keeping the ring tightly in contact with the inner wall of the thin-walled tube. It's that sealant that allows the ring to be pushed in from its original protruding position to just underflush with the flange, the way we've grown accustomed to seeing the front of the emitter.

So any machined parts would have to have the correct tolerance stackups to fit properly. That means measurements of the inner and outer diameters of the tubular walls will have to be done with calipers and micrometers. I have these tools and so does every machine shop, but they will charge considerably more upfront to reverse-engineer these parts as opposed to simply fabricating them from toleranced detail drawings, which I or another member (i.e., russep in the UK) could provide.

Whoever is the first to get their hands on an interconnector assembly in good condition is welcome to contact me to discuss reverse-engineering the parts. I'd of course do it for free just for the privilege.

If we can verify the correct parts are in the Mk 8 then that could be a realistic possiblity sooner rather than later.

As far as the stuff that appears to be between the ring and the flange, it could be a couple things.

It could be a high temp packing grease or, it could be (and this gets my vote) a crush ring.

It would be made of a softer metal, and designed to take up space and gaps as the two couplers are fit together. It probably gets inserted in the flange before before the "ring of holes" is inserted, just so the ring holds it in place instead of trying to get everything together before the crush ring fell out.

Now if we just get a replica of a super accurate knob....

I know, a different thread.

-Fred

 

[Prop Runner]

Good call on the crush ring, Fred - I was thinking it might be one, but was loath to think what it would mean if we decide to replicate the original construction... I'll get into the "yikes" aspect of that concern in a bit. If it is a crush ring, I wonder if the excess metal was cut or ground off the hero emitter or if the ring diameter is exactly the same as the flange (and is still attached on the screen-used emitter), so we can't even tell it's there. The cutaway diagram below bears out this possibility rather clearly:

The question remains then, do we duplicate EXACTLY the way the Ring of Holes is inserted into the flange, meaning having a crush ring stamped out of thin-gauge steel or aluminum or brass or copper (I can only speculate what it's made of right now) and no doubt using some sort of manual or hydraulic/pneumatic press and fixture (again - added cost of labor and machining, secondary cutting operation if the crush ring excess must be removed), or do we "cheat" and instead of the added cost of stamping and inserting a crush ring, we enlarge the Ring of Holes diameter by the thickness of the crush ring to enable a press-fit with the flange, and thicken the flange to duplicate the added thickness of the crush ring (assuming it's still there)?

Also, if I modeled the assembly correctly, I believe the inner tube is also press-fit into the Ring of Holes, probably before the RoH is pres-fit into the interconnector. Why am I certain of this? Look at the thin ring of "something" on the inside of the RoH:

To me it clearly represents the thin-walled inner tube that we see sticking out the back of the emitter.

Of course, this is all healthy speculation at this point, but details we should nevertheless discuss now in order to later avoid a fractious debate bewteeen proponents of "purist" vs. "idealized" replicas of the interconnector assembly. It could mean the difference between a $100 replica and a $250 replica.
