The biggest cue for CGI in these pictures are the textures on the bases. That and they are too perfetctly reflective. Mapping some scratches and scuffs and toning down the gloss would help imensely.
The Celestra is unchanged from the original show. The Bloackade Runner model didn't show up in the Classic BSG. The schematic design of the ship could be confused with a Corellian Corvette.
I just watched episode 10 and it is freakin' awesome. The show has upped the ante for sci-fi. I thought Farscape and Stargate were good. But this show is...Wow!
Any mechanical prototype machine produced part will need cleanup. Lots of it. And hand prototyping will take at least a couple hundred hours of work to do. So the short answer to your question is at least $3000. For a simple form. It really depends on the complexity of the original.
For hollow parts...get a slow setting resin and tumble the mold until the resin sets.
I made mine from sheet styrene rolled into a tube and glued the livinv p!$$ out of it. I glued the tube to a plate and made a lid out of 1/2" polycarbonate sheet. I waxed the lid with Johnsons Paste Wax and gooped silicone caulking onto the lip of the tube and pressed the lid onto it. (Let it dry for a couple of days or more. And don't lift it untill it's dry or you will make the seal not work.)
I Bored a hole into the lid to accept a hose connected to a venturi pump that I bought from Harbor Frieght for $14. A vaccuum guage would be nice if you can find one.
I can't recommend vaccum casting resins if you don't have a pressure chamber. The vaccuum makes the resin boil it's stinky components and they don't dissolve back unless you pressurize them. But for the rubber you just need to evacuate the chamber long enough for the bubbles to go away.
But to be even more clear; the treaded platform IS going to be available as a stand alone part to compliment the booster and base that I just ordered. Right?
If anyone is going to go through the trouble to cast a launch arm, they are likely to make the one as seen in the DYRL movie. The Hasegawa one is just an overworked display base. It doesn't really look like the on seen on screen.
My comment wasn't really directed to you in particular. The recast threads are all over the board right now. I'm just saying we need to be careful about the open discussions. This stuff thrives in the underground world of PM's and E-mail.
I really don't think Hasegawa is going to do the GPB kit. They have a pattern of completely exhausting the potential out of a tool before making a new one. They did every variant of the fighter before they did the Battroids. Once they did the Strike they went on to other things. They would have done it if they were going to.
