Thought I would post a couple pics of my progress with this awesome piece:

ss_emitter1.jpg


This is the result of many salt water baths, then light scrubbing, then heating the parts up over a gas stove flame, then cool off in salt water, lastly the parts sit outside overnight....repeat, etc, etc :)

I'm trying to capture the chronicles version which seems to be rusted a tiny bit (lighter areas under both the top emitter lip and under the next "step" down from the top of the emitter highlighted in RED) and it has a number of "bits" on the surface as well (highlighted in GREEN) that I believe are various deposits burned onto the piece:

Here are 2 pics of my piece next to the Chronicles piece:

What do you guys think?? love to hear your thoughts!! And let's see more emitters :)

Looks good! I don't think that's rust though. The bits are small scratches in the surface. The darker bands around it seem to be where the piece turned or rubbed inside the engine.

I have zero rust on mine but Serafino could give you a better answer.

Also from what I read, Inconel does not rust or corrode in any way under any circumstance.

Great pics FB! Thanks for the post! :):thumbsup

I'm wondering now how the original emitter got so dark and got so pitted, if it doesn't take any tarnishing? Keep the ideas/pics coming!! :)

-Ss
 
Scott- that's looking great!

It's going to be interesting now these parts are available to see members' versions of this saber - particularly, as you've done, matching the weathering details.
More!
 
Your emitter is looking great so far. Mine has already started to tarnish just by me handling it but im waiting for my steel grenade and then i will wether them together..

Are you planning on bashing the lip with a hammer or crimping it to match the screen used version?

I think I may scuff it up a bit more, to match the pitting as per the pics of FB's real found piece. I think the "crimping" that we see in the chronicles pics was found to be excess glue or epoxy though :confused....I'll defer to the Obi saber experts on that one. :)

Wow :eek

I am just in awe of the results you got here, absolutely amazing.

Franz B. is right about inconel, but that just means that it was weathered by other sorts of forces (i.e. EXTREME high heat). You've arrived at similar sort of pitting and discoloration by means which affect steel, and the results are fabulous.

From what I've seen, the only thing that seems to create a brownish color on original balance pipes is something that looks like streaks of burned resin, and it only showed up in 1 or 2 out of the 12 that I've seen. Small areas of darkness sometimes appear, and on some the small tube appears to have been black originally as on FBs. I've not seen one that was entirely blackened though. This is part of why seeing the Tunisia and Death Star corridor forms of the saber tends to make one think of paint.

As to the apparent 'crimping' of the small tube, that wall is pretty thick. I don't know what happened to that thing to make it look that way--now that I think about it maybe it was burned or melted.

Glue or solder--that was the theory about the 'globs' inside the small tube where the grenade stem attaches. There may be some solder among the 'crimp' effects on the small tube, but to me what stands out is the crescent-shaped gaps in the edge.

Maybe the Chronicles balance pipe is from an engine that was engulfed in flame, who knows.

I can confirm about the Inocel. The IG88 heads I found are also made of it. No sign of rust on them but in some light the thing has a very slight brown tint to it, almost like dark bronze. But they are covered in all sorts of dark patches.
 
FB, how'd you get the pitting on yours?

So, who's going to chip away the edges of their outer flange and risk irreversable damage? ;)

That is a real one so all I had to do was find it! :lol

I think all the crimping, bent and mangled areas are just glue. It's near impossible to bend one of these things.

Oops yeah I didn't mean flange, I was talking about the "chips" out of the edge of the larger "tube", the relatively sharp edge has some chips out of it or something.

Ah ok FB, I thought that was a pic of a replica...these replicas are too good. ;)

So I guess my question should be to Scott, how'd you get the pitting on yours or was that just a result of the rust?
 
Regarding the mangled/chipped areas:

The inner tube is darker in color (whether it be paint or soot). What you're seeing at the bootom of the chronicles inner tube are areas where the paint/soot is scratched off, revealing a much brighter appearing Inconel. It's an optical illusion essentially. There may be a chip or sliver missing on the thinnest part of the taper at the bottom, but the rest is smooth and round.

Take a match or candle flame, and blacken the metal. Then take a piece of crumpled tinfoil or a rough rock or something, and scrape away little areas of the blackened soot. It'll look just like the chronicles pic...so long as you're looking at it in black and white. That's what causes the optical illusion. If we had a clear color shot of that area, you'd be able to tell without a doubt that those aren't dents.

Inconel alloys are oxidation and corrosion resistant materials well suited for service in extreme environments. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally-induced crystal vacancies (see Arrhenius equation). Inconel's high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy. In age hardening or precipitation strengthening varieties, small amounts of niobium combine with nickel to form the intermetallic compound Ni3Nb or gamma prime (γ'). Gamma prime forms small cubic crystals that inhibit slip and creep effectively at elevated temperatures.

Not that I am arguing the durability of the inconel, but there is at least one spot, most likely two based on the photo, that show some form of damage to the thicker inner tube. The outer thinner tube looks to have about 4 damaged spots in my eye. Who knows what caused them, perhaps an engine blew up and the balance pipe took damage?
 
Yeah, like I said, there are definitely some chips/slivers missing on the very bottom of the tubes where they're at their thinnest. I was talking about the "mangled dents" above.

It's the same optical illusion that had so many people thinking there was an indented circle on the bottom of the Blade Runner Blaster grip, but it turned out just to be scrapes in black paint, that just happened to be shaped in a way that an illusion of depth was created.
 
I would add the three areas circled in violet. I’m not sure I’m exactly disagreeing with TCW though, since 2 of these 3 areas of distortion could possibly be limited to the area of the chamfer:

Left–the edge shape is distorted

Middle–a crescent-shaped bite is missing from an area of very strong highlight. Even black material would show lighter in this area if it was the same angle to the light as the material to either side.

Right–(my circle is a little low) it may look like the chamfer, but in fact it’s at the wrong angle, clearly there is material missing here.

Also, TCW, although it doesn't really affect the issue, can you say whether the information you posted reflects practices in place in the early 1950's?

HAH! Allow me to take this opportunity to brag that I was one of the very few on the side of the angels on that issue! Oooh those people who did not understand how light works were so irritating! :p

I'm not sure I understand the question. Which information (I've been spewing out a lot)?
