I am continuing work on my EE-3 Carbine and am modeling the large discs that go behind the connecting rod on the breech. I have seen this made/modeled a number of different ways, and here is what I have so far. This is probably slightly more complex on the center post than you are used to seeing, but I built it this way so it snaps into the various rings on the connector rod for a more firm hold. I also have a recess in the back to hold a 20X3mm N52 rare earth magnet.
I'd like to get your thoughts/feedback. My two main concerns are the overall thickness and the outside edge (I have seen this modeled dozens of different ways.
Its definetly hard to say how it "should exactly" be, this seems like a really nice way to go about it though i like the idea of it snapping together as for the edge and the thickness i like the edge how it is and im not positive about the thickness but i think it should be just a bit thicker than a loonie which is almost 2 mm so maybe try like 2.2 or 2.4 mm?
sorry!! Lol i just woke up I meant to say 3.2 or 3.4 lol that .2 or 4 is a minnescule difference my bad haha , are you printing the pieces? Its not a very big piece maybe just print a tester just to actually have it in your hand and see if your happy with it.... i think youve got it pretty much spot on
I went a similar route as you've gone when I did my disk the first time (I'm actually redoing them again now too hahaha. Foundparts builds are never done!)
The thickness on mine is 3.5mm if I remember right
I think that you have the thin lip spot on, and from shadow inferences I think the rest of the shape is pretty correct too. I can't decide about the center, whether it is actually philips or some other more unusual shape.
I think it looks great, Art.
I know this thread is old, but just wanted to ask what the genersl consensus is on these amongst the Fett/SW community.
Speaking generally, are these discs:
1. Real Found Parts
2. Were fabricated by crew
3. There’s just no way of knowing
Seems to me since most other greebs on this blaster are real found parts, it would not make much sense for the propguys to fabricate a part that is for a blaster that no filmgoer would know the design to. What I mean is there wasn't a predetermined design they (the propguys) had to follow when greebing this thing out so it would have been just as easy (much easier, really) to simply go with a completely different part than the disc than it would be to fabricate something entirely new.
Has anyone come up with general dimensions of these discs (like diameter of the disc and inner rings)? I am in deep right now with vintage Video Decks and might be able to find some worthy candidates once dims are spec’d. Thanks for mocking up the discs and posting this thread, Art.
Do we know when the prop guys made this? Was it just before/during production of ESB, or had it been around since before PreProduction? It was post Supertrooper. What else were they working on at that time?
These are just the Futaba control wheels, the other RC manufacturers had there own versions. These wheels are something that would have been easy to come by in a SPFX house, every servo came with a selection of control horns. Years ago I use to have a box of them. Just a thought.
The inside is even more interesting, although I am sure the scale is way off:
I love that last photo, however it is way too wide. According to the site, the diameter of the center hole is 6mm. 1.5 inches puts the total estimated diameter of the breech disc at about 38mm based on Art’s estimated breech disc diameter. That would make the breech disc have a diameter about as wide as the inner lowered section with the three holes in it, thus this disc is very very large.
Obviously those upper photos show the real world disc being too thick. Perhaps they would have turned it down?
From scrutinizing those two screen grabs you posted up there Art Andrews I surmise that the circular breech greeblies are not just discs, but are pulley wheels.
This would be an unnatural phenomenon based on the curvature of the breech at that very location.
Also, the top most dark area looks dark enough to be a cutout for securing a line, as one would find on many pulley wheels like this one taken from a WWII RAF fighter plane:
TWO DISTINCT EDGES FOR PARALLELED QUARTER CIRCLES
I realize with my red lines in the picture, covering up the two edge lines, they can’t really be viewed, so you will need to enlarge the top photo and look there.
